    Analgesic Activity of some 1-Phenyl-3-aryl-5- (4-(butanoloxy) phenyl) 1H-pyrazoles
    (Chitkara University Publications, 2016-11-02) Anju Goyal; Sandeep Jain
    A series of analgesic activity of synthesised 1 -Phenyl-3-aryl- 5-(4-(butanoloxy) phenyl) 1H-pyrazoles were synthesized from chalcones and screened for their in vitro analgesic activity. Chalcones i.e.,1-aryl-3- (4-hydroxyphenyl) prop-2-en-1-ones, 1 on reaction with phenyl hydrazine in presence of acetic acid and few drops of hydrochloric acid furnished the corresponding 1-phenyl-3-aryl-5-(4-hydroxyphenyl)-1H-pyrazoles 2 which on further reaction with 4-chloroalkanol yielded the title compounds 3. These compounds were characterized by CHN analyses, IR, mass and 1H NMR spectral data. All the novel synthesised 1-Phenyl-3-aryl-5-(4-(butanoloxy) phenyl) 1H-pyrazoles were evaluated pharmacologically for their analgesic activity and the title synthesised compounds exhibited significant results as compared to standard drug.

    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 Goyal
    A 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. The proposed RP-HPLC method was developed on phenome-nex LunaR C-18 5μm,250 mm × 4.6 mm id. 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.

    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 Pathak
    Benzimidazole, 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.
