A series of novel 2-(5-hydroxy-5-trifluoromethyl-4,5-dihydropyrazol-1-yl)-4-(coumarin-3-yl)thiazoles (6) were synthesized by condensing 3-(2-bromoacetyl)coumarins (4) with various 5-hydroxy-5-trifluoromethyl-4,5-dihydropyrazol-1-thiocarboxamides (5), obtained by the reaction of thiosemicarbazide with trifluoromethyl-β-diketones. All the tested compounds(More)
A recombinant plasmid pTargeT.rabgp containing the glycoprotein (G) gene of Rabies virus (RV) was constructed and produced for immunogenicity studies on mice and dogs. The mice immunized twice with 50 microg or 100 microg of pTargeT.rabgp intramuscularly (i.m.), showed a serum antibody titer of 256 or 64, respectively 14 days post immunization (p.i.). When(More)
Synthesis of total eighteen 2-amino-substituted 4-coumarinylthiazoles including sixteen new compounds (3a-o and 5b) bearing the benzenesulfonamide moiety is described in the present report. All the synthesized target compounds were examined for their in vivo anti-inflammatory (AI) activity and in vitro antimicrobial activity. Results revealed that six(More)
The Chir Pine, Pinus roxburghii, named after William Roxburgh, is a pine native to the Himalaya. Pinus roxburghii Sarg. (Pinaceae) is traditionally used for several medicinal purposes in India. As the oil of the plant is extensively used in number of herbal preparation for curing inflammatory disorders, the present study was undertaken to assess analgesic(More)
A new series of pyrazolylpyrazolines (5a-k) was synthesized by the reaction of appropriate chalcones (3a-k) with 4-hydrazinobenzenesulfonamide hydrochloride (4) in ethanol. All the newly synthesized target compounds (5a-k) were screened for their anti-inflammatory activity using carrageenan-induced rat paw edema assay. Compounds 5g and 5j showed pronounced(More)
A new series of 1-(4-aminosulfonylphenyl)-3,5-diaryl pyrazolines (5) was synthesized by the reaction of appropriate chalcones 3 with 4-hydrazinobenzenesulfonamide hydrochloride (4) in ethanol in the presence of catalytic amount of acetic acid. All newly synthesized compounds were in vivo evaluated for their antiinflammatory activity using(More)
OBJECTIVE To study the anticonvulsant activity of alcoholic extract of bark of Pinus roxburghii Sarg. (AEPR) used in Indian traditional medicine system in treating convulsion. METHODS Anticonvulsant activity was evaluated by maximal electroshock (MES) and pentylenetetrazole (PTZ)-induced seizures in Wistar albino rats. In the MES model, 150 mA current for(More)
The present article describes the synthesis of two novel series of thiosemicarbazones 3 and thiazolylhydrazinomethylidenepyrazoles 5. All the newly synthesized target compounds (3a–e and 5a–o) were screened for their in vivo anti-inflammatory (AI) activity using carrageenan-induced rat paw edema assay and in vitro antibacterial activity against two(More)
Traditional medicine systems consist of large numbers of plants with medicinal and pharmacological importance and hence represent an invaluable reservoir of new bioactive molecules. Alpinia galanga (family Zingiberaceae) is commonly known as galangal and has been used for its emmenagogue, aphrodisiac, abortifacient, carminative, antipyretic and(More)
A novel series of heteroaromatic analogues of known anti-inflammatory (AI) drug celecoxib replacing the benzenesulfonamide moiety with 6-sulfonamidobenzothiazol-2-yl moiety was synthesized. Regioselective synthesis of the target compounds 2a–i having 1,5-diaryl relationship was achieved by exploring reaction conditions. All the newly synthesized compounds(More)
