Item Advances in Magnetofection & − Magnetically Guided Nucleic Acid Delievery:a Review(Chitkara University Publications, 2013-05) Sandeep Arora; Girish Gupta; Sukhbir Singh; Neelam SinghThe aim of this work was to investigate the effects of the nature and concentration of cellulose derivatives on the release kinetics of ibuprofen from hydrogel matrices using a response surface method (RSM). A series of cellulose derivatives, as methyl, hydroxyethyl, hydroxypropyl and hydroxypropyl methyl celluloses (MC, HEC, HPC and HPMC) were used as polymer platforms and their impacts on drug release were studied and compared to those obtained with a reference formulation prepared with HEC. It was shown that the use of HPMC in the gel formulation contributes to the improvement of drug release and consequently its biodisponibility. Indeed, the increase in HPMC concentration forms a controlled system release because polymer chains relaxation. The drug is released under the effects of two phenomena: diffusion and relaxation of polymeric chains. Thus, the kinetic release passes from the kinetics of case II towards Fickian diffusion.Item In Vitro Anti-Staphylococcal Activity of Alkaloids from the Leaves of Callestimone Rigidus R.Br(Chitkara University Publications, 2013-05) Charu Gomber; Sanjai SaxenaMultidrug resistant Staphylococcus aureus poses a severe global threat worldwide due to their prevalence, genomic plasticity and limited therapeutic options being refractory to most antibiotic classes. This necessitates the discovery of new anti-staphylococcal interventions. Callistemon rigidus R.Br. (Myrtaceae) has been found to possess antibacterial potential against clinical isolates. Thied me study was a isolate and evaluate the antibacterial alkaloids from the leaves of Callistemon rigidus and assess their in vitro anti-staphylococcal potential. Alkaloid isolation was carried out by modiied method for plant alkaloid extraction. The in vitro anti-staphylococcal potential of the alkaloid bioactive fraction was assessed by using micro broth dilution and plate count assay methods. Pus and wound isolates had MIC of 80 µg/mL and 50 IC of 27.22 µg/mL respectively. Burn isolates showed MIC of 320 µg/mL and 50 50 13.57 µg/mL respectively. Urine and vaginal isolates exhibited a MIC of 80 µg/mL 50 and IC of 13.15 µg/mL respectively. Ceixime had MIC values was 320 µg/mL, 160 50 50 µg/mL and 160 µg/mL for pus and wound, burn, urine and vaginal isolates indicating the refractory behaviour when compared to alkaloid bioactive fraction from the leaves of Callistemon. The alkaloid bioactive fraction exhibits immense activity compared to standard antibiotic Ceixime. This work is the irst report of alkaloids and their antimicrobial activity from Callistemon rigidus leaves. The results suggest further isolation of individual alkaloids from alkaloid bioactive fraction and assessment their anti-staphylococcal activity as leads for development of anti-staphylococcal drugs.Item Surfactants: Pharmaceutical and Medicinal Aspects(Chitkara University Publications, 2013-05) Bhupinder Singh SekhonSurfactants are amphipathic substances with lyophobic and lyophilic groups and are critical components in pharmaceutical products. Surfactants have several uses in pharmaceuticals, i) for solubilisation of hydrophobic drugs in aqueous media, ii) as components of emulsions ,iii) surfactant self-assembly vehicles for oral and transdermal drug delivery, iv) as plasticizers in semisolid delivery systems, and v) as agents to improve drug absorption and penetration. Non-ionic surfactants such as ethers of fatty alcohols are most commonly used in pharmaceuticals. Cationic surfactants are capable of exerting antibacterial properties by disrupting bacterial cell membranes. In pharmaceutical processing, phospholipid lecithin, bile salts, certain fatty acids and their derivatives have become indispensable since they afford a uniquely effective and eficient mechanism of drug carriage by solubilising the drugs of fatty origin. The antibacterial, antifungal and antiviral activities make biosurfactants relevant molecules for applications in combating many diseases and as therapeutic agents. Biosurfactants have the potential for use as major immunomodulatory molecules, as anti-adhesive biological coating for biomaterials, in vaccines and gene therapy, and they may be incorporated into probiotic preparations to combat urogenetical tract infections and pulmonary immunotherapy. Gemini surfactants are effective potential transfection agents for non-viral gene therapy. Ionic liquids act as secondary surfactants and the use of surfactant/ionic liquid systems should be explored to build speciic properties in the organized medium, and to explore pharmaceutical applications of traditional, biosurfactant and Gemini surfactants.Item Synthesis and Pharmacological Evaluation of Some Novel Imidazole Derivatives for Their Potential Anti-hypertensive Activity(Chitkara University Publications, 2013-05) Anju Goyal; Jitender Singh; Dharam Pal PathakBenzimidazole, which is a heterocyclic nucleus, plays an important role in various medicines. A number of therapeutic agents such as H1 antihistaminic agent clemizole, a potent opioid analgesic etonitazene, nonnucleoside antiviral compound enviroxime, for promotion of excretion of uric acid irtemazole, non sedating antihistaminic agent astemizole, anti ulcer drugs omeprazole and pentoprazole, antihelmintic thiabendazole, antinematodal nocodazole etc. are based on benzimidazole heterocyclic nucleus. The synthesis of various benzimidazole derivatives by the reaction of ortho phenylene diamine I with various organic acids to yield 2-substituted benzimidazole derivatives II which on further treatment with nitric acid and sulphuric acid yielded 5-nitro-2-substituted benzimdazoles III. Coupling of this compound with halogenated beta picoline V yielded the title compounds. The structures of synthesized compounds were elucidated mainly by spectral evidence. All the compounds were screened for their anti-hypertensive activity. The compounds exhibited moderate to signiicant activities.Item Modified Excipients in Novel Drug Delivery: Need of the Day(Chitkara University Publications, 2013-05) Neha Kanojia; Loveleen Kaur; Manju Nagpal; Rajni BalaDrug products not only contain “actives” that confer the intended therapeutic benefits such as pain relief or act on particular part of the body, but contain other materials that are also “functional” with respect to the drug product. These are known as excipients and specific functionality which they confer to a particular product is independent upon the process used to add the excipient to the formulation and its exact location within the final dosage form. Introduction of novel drug delivery systems and new drug moieties lead to the need for new excipients with varied characteristics. Development of new excipient entities and their evaluation is a costly procedure; modification of existing excipients is very easy, more economical and less time consuming. The development of excipients that are capable of fulfilling multifunctional roles such as enhancing drug bioavailability and drug stability as well as controlling the release of the drug according to the therapeutic needs is one of the most important prerequisites for further progress in the design of novel drug delivery systems. The main focus of this article is on synthetic novel excipients that perform multiple functions in pharmaceutical formulations.Item Cytoprotective Activity of Adhatoda Vasica Extract and Vasicine Against Tobacco Smoke Induced Cytoxicity(Chitkara University Publications, 2013-05) Rachana; Mamta Pant; Sujata BasuThe present study was undertaken to investigate the protection against cytotoxicity due to tobacco smoke by Adhatoda vasica and Vasicine. The antioxidant potential of AVE was analyzed through in vitro assays. The protective effect of Adhatoda vasica extract (AVE) and vasicine were analyzed in TSE treated group through MTT assay and microscopic analysis.A dose dependent increase in reducing power of AVE was observed. Treatment of A549 & THP-1 cell lines with 1-2 µg/ml (AVE) & 0.01-0.02 µg/ml (Vasicine) respectively for 3 hrs maintained the cell viability. Approximately 50% cell death was observed at 2% & 5% TSE on 24 hrs exposure. Pre-treatment of cell lines with AVE & Vasicine (2µg/ml & 0.02 µg/ml) respectively could overcome the toxic effect of TSE. This study showed that AVE has a great potential in reducing the toxic effects of A549 &THP-1 cell lines.Item Investigation of the Effects of Cellulose Derivatives on the Kinetics of Drug Release from Cellulose-Based Hydrogel Using a Response Surface Method(Chitkara University Publications, 2013-05) S.

Amarus and its Tablet Formulation(Chitkara University Publications, 2013-05-15) Arora, Sandeep; Sharma, Arvind; Kaur, ParneetPresent investigation was aimed at formulation, characterization and evaluation of phytosomal complex tablets for sustained delivery of Phyllanthus amarus complex. Phyllanthin, one of the active lignin present in this plant species was isolated from the aerial parts, by silica gel column chromatography employing gradient elution with hexane −ethyl acetate solvent mixture. It was obtained in high yields (1.23%), compared to reported procedures and the purity was ascertained by HPTLC analysis. Phyllanthin was characterized for M.P, UV −Visible spectrophotometry, FT-IR, 1H NMR, 13C and NMR analysis. Release kinetics was evaluated by using United States Pharmacopeia (USP)-22 type I dissolution apparatus. Scanning electron microscopy was used to visualize the effect of dissolution medium on matrix tablet surface. HPTLC was carried out for quantitative and qualitative estimation of Phyllanthin in Phyllanthus amarus and Rf of phyllanthin was found to be about 0.25. The content was found to be maximum for phytosomal complex of phyllanthus formed by vaccum drying of 1:1 drug excipient ratio. The in-vitro drug release study revealed that optimized formulation sustained the drug release for 12 hr (88.1% ± 4.1% release). Fitting the in vitro drug release data to Korsmeyer equation indicated that diffusion along with erosion could be the mechanism of drug release.Item Assessment of Suspending Properties of Katira Gum: Formulation and Evaluation of Nimesulide Suspension(Chitkara University Publications, 2013-11) Inderbir Singh; Amrinder Singh; Garima Thakur; Oluwatoyin A. OdekuThere are several hydrophilic polymers that have been employed as suspending agents in pharmaceutical suspensions due to their ability to form colloidal gel in aqueous medium. In the present study, katira gum obtained from the bark of Cochlospermum religiosum has been evaluated as suspending agent in nimesulide suspension and compared with acacia gum at concentration of 1-5%. Sedimentation volume, rheology, particle size, degree of flocculation and in-vitro drug release were employed as assessment parameters. The result showed that at all concentrations, katira gum higher suspending capability compared acacia gum. The sedimentation volume was found to increase from 0.36 to 1 (A1-A3) and 0.26 to 0.56 (B1-B3). The viscosity of suspensions (A1 and A2) containing gum katira as suspending agent was found to be 1.35 and 2.4 centipoise and 0.63- 1.05 centipoise (B1- B3). Plots between shear stress and rate of shear were plotted using different concentrations indicates the obedience to newtonian behaviour. Degree of flocculation of gum katira and gum acacia suspension was established to be 1.69 and 1.05 respectively.Item Analytical Method Development and Validation for Assay of Rufinamide Drug(Chitkara University Publications, 2013-11) Jitender Singh; Sonia Sangwan; Parul Grover; Lovekesh Mehta; Deepika Kiran; Anju GoyalA simple, rapid, sensitive, cost effective, and reproducible reverse phase high performance liquid chromatographic (RP-HPLC) method was developed and validated for the stability testing of rufinamide.

Column (at ambient temperature) and a mobile phase consisting of phosphate buffer: acetonitrile (60:40) was delivered at a flow rate of 1.0ml/ min. The analyte was detected by using a UV detector at the wavelength of 293 nm. The method was found to be linear over the concentration range of 50- 150 μgml-1 (r2=0.999). 30. The retention time of rufinamide was 4.717 min.Item Development and Optimization of Fast Dissolving Tablets of Losartan Potassium Using Natural Gum Mucilage(Chitkara University Publications, 2013-11) Rohit Goyal; Manju Nagpal; Sandeep Arora; Gitika Arora DhingraCurrent research work involves preparation of fast dissolving tablets of Losartan Potassium by direct compression method using different concentrations of Plantago ovata and Lepidium sativum mucilage as natural superdisintegrants. A two factor three level (32) factorial design is being used to optimize the formulation. Nine formulation batches (A1-A9) were prepared by taking two factors as independent variables (X1- amount of Plantago ovata mucilage and X2- amount of Lepidium sativum mucilage) were taken with three levels (+1, 0, -1). All the active blends were evaluated for precompression parameters (angle of repose, bulk density, carr’s index, hausner’s ratio) and formulated tablets were evaluated for post compression parameters (hardness, friability, weight variation, wetting time, disintegration time, water absorption ratio). In vitro drug release studies were carried out using USP II dissolution apparatus for 30 min. The software Design Expert (8.0.7.1) was used for generating experimental design, modeling the response surface and calculating the statistical evaluation. Tablet parametric tests of formulation batches (A1-A9) of FDT were found within prescribed limits. DT was observed in the range from 12±2 to 58.7±2.52 sec and WT from 10.3±1.52 to 49.7±5.13 sec for formulation batches (A1-A9). More than 87% drug release was observed in all formulation batches (A1-A9) within 15 minutes. Polynomial mathematical models, generated for various response variables using multiple linear regression analysis, were found to be statistically significant (P < 0.05). Formulation A7 was selected by the design expert software which exhibited DT (22.15sec), WT (17.31sec) and in vitro drug release (100%) within 15 minutes.Item An Ethanol-Based Proliposome Technology for Enhanced Delivery and Improved “Respirability” of Antiasthma Aerosols Generated Using a Micropump Vibrating-Mesh Nebulizer(Chitkara University Publications, 2013-11) Abdelbary M.A. Elhissi; Jasmeet Brar; Mohammad Najlah; Simon A. Roberts; Ahmed Faheem; Kevin M.G. TaylorSalbutamol sulphate liposomes were generated using ethanolbased proliposomes followed by nebulization using an Aeroneb Pro vibrating-mesh nebulizer. The droplet size, output and fine particle fraction (FPF) of the drug incorporated in liposome formulation were compared to those of a conventional drug solution. Aerosol output was determined gravimetrically and drug output was analyzed by using high performance liquid chromatography. The potential of aerosol deposition in deep lung was evaluated using inertial impaction and laser diffraction. The effect of formulation surface tension on the aerosol performance was studied. Output and FPF were improved using liposomes compared to the conventional solution, for instance, FPF values were 57.85% and 45.81% respectively. The volume median diameter as measured by laser diffraction was respectively 3.44 μm and 3.22 μm; however, the higher FPF of the liposome formulation is justified by the lower polydispersity of its aerosol. The improved aerosol performance using liposomes was attributed to the reduction of surface tension caused by the presence of phospholipid. This is the first study that demons trates the ability of liposomes to improve the nebulized drug output and FPF.Item Association of ABO Blood Groups with Cardiovascular Diseases in Adult Indian Population(Chitkara University Publications, 2013-11) Pooja Sahita; Indermeet Singh Anand; Manisha ShahThis study was designed to investigate whether there was an association between ABO blood groups and major cardiovascular diseases (ischemic heart diseases) in adult Indian population. The present retrospective study analyzed ABO blood groups among 1527 patients with documented IHD, who were treated at CIMS Hospital in Ahmedabad city from January to December, 2011 comparing with a control group of 860 subjects. Data were analyzed with GraphPad Prism 6.0 and by using chi square test. A p-value less than 0.05 were considered as +statistically significant. No significant difference in distribution of ABO blood groups was seen in patients with IHD (A, 21.95%; B, 35.41%; AB, 8.61%; O, 34.01%) and also after adjustment for common cardiovascular risk factors such as age, gender, addiction history, obesity, hypertension, diabetes in these patients (A, 25.47%; B, 37.53%; AB, 9.04%; O, 27.94%) as compared to the controls (A, 22.32%; B, 35.58%; AB, 8.83%; O, 33.25%), p-value = 0.9916 and 0.2778 respectively. The findings of the study suggest that there seems to be no correlation between various ABO blood groups and development of cardiovascular diseases. Moreover, the prevalence of major risk factors was equal in patients with different blood groups and blood groups had no impact on development of cardiovascular pathogenesis in individual subjects.Item Development and Validation of Static HS-GC Method for the Determination and Quantification of Residual Solvents of Bromhexine Hydrochloride (BHX)(Chitkara University Publications, 2013-11) Prafull Mathur; Suvigya Mathur; Anand Kumar Mishra; Tanaji KunjirThe determination of residual solvents in drug substances is the mandatory requirement by various health authorities in the world. There are no analytical methods available in the literature that can simultaneously separate and quantitate residual solvents in bromhexine hydrochloride (BHX) active pharmaceutical ingredient (API). This paper describes the development and validation of a simple, efficient, accurate, and robust static headspace gas chromatography method for the determination of residual solvents, namely methanol, ethanol, ethyl acetate, monochlorobenzene, and benzene, in BHXAPI. This new method has been demonstrated to be accurate, linear, precise, reproducible, specific, and robust for its intended purpose. The method gives very good sensitivities viz. detection limits for benzene is 0.4 ppm, ethyl acetate 2 ppm and for others solvents 5 ppm and precision (below 9.0 % RSD) for all solvents. The results of this evaluation strongly indicate that this method can be readily used to determine residual solvents in BHX.Item Receptor Identification: Advances in Ligands and Transmitters Discovery(Chitkara University Publications, 2014-05) Sandeep Arora; Govindrajan Raghavan; Avaneesh KumarReceptor identification is an integral part of drug discovery and development. By the beginning of the next millennium, the search for the natural ligands of the orphan G-protein-coupled receptors will lead to the discovery of so many new peptides that it may well double their present number. It has recently become evident that all types of chemical messengers, hormones and transmitters act through membrane receptors which constitute our largest superfamily of proteins, i.e. the G protein-coupled receptors. The development of targeted therapies has revolutionized the treatment of various chronic diseases. Receptors have well-conserved regions that are recognized and activated by hormones and neurotransmitters. These ligands are peptides, lipids or biogenic amines, and act as transmitter molecules. Identification of orphan receptors include screening, binding and reverse engineering that help to find out cysteinyl leukotriene CysLT1 and Cys T2, hepatointestinal leukotriene B4, motilin, Ghrelin, Growth hormone-releasing peptide and growth hormone secretagogue receptor and many more. Techniques involved in screening of receptors include low stringency hybridization followed by PCR-derived approaches helps to discover various orphan g protein couple recptors (oGPCR). The discovery of the oGPCR represents a hallmark in neuroscience research, and the exploitation of its numerous physiological and pathophysiological functions is a promising avenue for therapeutic applications.Item Sustained Release Solid Dispersions of Pentoxyfylline: Formulation and Optimization(Chitkara University Publications, 2014-05) Sandeep Kumar; Manju Nagpal; Kalpana Nagpal; Gitika Arora DhingraObjective: The purpose of the study is to formulate and optimize sustained release solid dispersions of pentoxyfylline using a combination of eudragit polymers and ethyl cellulose. Methods: Solid dispersions were formulated by solvent evaporation method.Preliminary batches were formulated using various drug to polymer ratio; with eudragit S100 and L100 (1:1 to 1:5 ratio), and with ethyl cellulose(1:1 to 1:3 ratio) and evaluated for solubility analysis. Based on results of preliminary batches, Box Behnken design was further applied and three factors (X1- concentration of Eudragit S100, X2- concentration of Eudragit L100, X3- concentration of Ethyl Cellulose) were selected with three levels (+1, 0, -1). Multiple linear regression was applied to generate polynomial equations and statistical evaluation. Prepared solid dispersions were investigated for sustained release properties via in vitro dissolution studies. Fourier transform infrared spectroscopic analysis (FTIR), X-ray diffraction analysis (X-RD), Differential scanning calorimetry (DSC) studies were carried out to evaluate drug polymer interactions. Scanning Electron Microscopy (SEM) analysis of optimized solid dispersion was carried out to evaluate surface morphology of the particles. Results: Batch F5 showed maximum sustained release (65.46% in 24 h) characteristics out of all solid dispersions. DSC studies indicated drug integrity when mixed with the polymeric carriers. FTIR and X-RD studies also ruled out any drug polymer interaction. A change in crystalline habit was observed in solid dispersion particles (F5 batch) as seen in SEM micrographs. Polynomial mathematical model generated using multiple regression analysis was found to be statistically significant (p<0.05). Conclusion: Release retarding effect was found to be dependent on polymer concentration. Therefore, an optimized combination may lead to better sustaining effect.Item Estimation of Total Phenols and Flavonoids in Selected Indian Traditional Plants(Chitkara University Publications, 2014-05) Deepak Kumar; Anupam Jamwal; Reecha Madaan; Suresh KumarTraditionally, aerial parts of Abies pindrow Royle (Himalayan Fir; Pinaceae); Abies webbiana Lindl. (Talispatra; Pinaceae); Cephalandra indica Naud. (Ivy Gourd; Cucurbitaceae) and roots of Calotropis gigantea (L.) Dryand (Giant Milkweed; Asclepiadaceae) have been used in the Indian systems of medicine for the treatment of various ailments. But no systematic phytochemical work has ever been carried out on these potential plants. Thus, it was planned to estimate total phenols and flavonoids content in methanol extract, ethyl acetate fraction (EAF) and remaining methanol extract (RME) of selected plants. Properly identified plants were defatted with petroleum ether, and then separately extracted in a Soxhlet apparatus with methanol. The methanol extract of each plant was partitioned by ethyl acetate solvent to obtain EAF of respective plant. The total phenols and flavonoids contents were estimated using standardized procedures. Quantitative determination of total phenols and total flavonoids was done using standard curve of gallic acid (linearity: 20 to 120 mg/ml; r2 = 0.995) and quercetin (linearity: 30 to 180 mg/ml; r2 = 0.997), respectively. EAF of selected plants contained higher content of phenols and flavonoids, where as lowest content was observed in RME of plants. The content of total phenols and flavonoids in selected plants were found to be in order of C. indica > A. webbiana > A. pindrow > C. gigantea. The available literature reveals that polyphenols have been reported to possess varied pharmacological activities. As selected Indian plants contain polyphenols as major class of phytoconstituents, it is suggested that these constituents may be responsible for their medicinal uses.Item Formulation, Optimization and Evaluation of Sustained Release Microspheres using Taguchi Design(Chitkara University Publications, 2014-05) Sukhbir Singh; Sandeep Arora; Neelam; Dharna AllawadiThe aim of present study is to prepare microspheres of eudragit RL 100 loaded with Nefopam Hydrochloride by single emulsion solvent evaporation technique. Taguchi L9 orthogonal array design has been used to optimize the composition and operating conditions for preparation of formulations. Nine batches (F1-F9) were prepared by taking three independent variables (X1- drug: polymer ratio, X2- stirring speed and X3- stirring time) at three levels (+1, 0, -1). Response variables studied for batches (F1-F9) were mean particle size (μm) (Y1), drug entrapment efficiency (% w/w) (Y2) and drug loading (% w/w) (Y3). Drug- polymer compatibility study was carried out by DSC and FTIR spectroscopy and indicates no physicochemical interaction. Microspheres were analyzed for morphological characteristics, mean particle size, drug entrapment efficiency, drug loading and in-vitro drug release. Percentage cumulative drug release for optimized batch F5 was found to be 85.421 ± 0.054 and followed higuchi model for release of drug.Item Synthesis, antimicrobial evaluation and QSAR studies of p-amino benzoic acid derivatives(Chitkara University Publications, 2014-05) Meeta; Pradeep Kumar; Balasubramanian NarasimhanA series of Schiff bases (1-16) and esters (17-27) of p-amino benzoic acid (PABA) was synthesized and its in vitro antimicrobial potential was evaluated by using tube dilution method. Compound 11 was found to be most promising antibacterial agent (pMICbs = 2.11 μM/ml) having antibacterial potential comparable to standard drug norfloxacin (pMICbs = 2.61 μM/ml) and may be taken as a lead compound for the development of novel antibacterial agents. QSAR analysis indicated that electronic parameters, total energy (Te) and energy of lowest unoccupied molecular orbital (LUMO) were found dominant in explaining the antimicrobial activity of synthesized compounds.Item Pharmacogenomics: Applications in Drug Discovery and Pharmacotherapy(Chitkara University Publications, 2014-05) Hitesh Chopra; Sandeep Kumar; Vandana; Sandeep AroraPharmacogenomics is the scientific study which explains individual variability of drug targets and to explore the genetic basis for such changes. With the completion of human genomic study, clear relation could now be established between the drug response in relation to a person’s genome. Pharmacogenomics, also known as personalized medicine, uses the person’s genome to determine the dose and dosage regimen, so that therapy could be optimized. As with the techniques like DNA microarray technologies person’s response to a therapy can be predicted and new therapies could be assigned. In the present review, the current technologies, and past significance has been discussed.
