A series of [5-substituted-4-phenyl-1,3-thiazol-2-yl] benzamide and furamide analogues were investigated in radioligand binding studies at adenosine receptor subtypes with an aim to obtain potent and selective adenosine receptor ligands. Benzamide and furamide linked to thiazole was found to be crucial for high adenosine receptor affinity. The most potent(More)
We have investigated the hypolipidemic effects of swertiamarin an active lead isolated from a perennial herb Enicostemma littorale Blume. in high cholesterol fed rats. Swertiamarin (50 and 75 mg/kg) and atorvastatin (50 mg/kg) was given orally daily for seven consecutive day to the high cholesterol feed rats. Serum total cholesterol, triglycerides, low(More)
Dyslipidaemia is one of the major risk factors for cardiovascular disease in diabetes mellitus. Lipid changes associated with diabetes mellitus are attributed to increases in free fatty acid flux, secondary to insulin resistance. In the present study, we have investigated the beneficial effects of swertiamarin on dyslipidaemic conditions associated with(More)
Substituted thiazoles with different structural features were synthesized and screened for their anti-inflammatory activity in acute carrageenin induced rat paw edema model and chronic formalin induced rat paw edema model. The compounds 1-5 showed 83, 30, 63, 69 and 73% protection, respectively, in acute carrageenin induced rat paw edema model. In 5-day(More)
Sets of tetrasubstituted thiophene esters 4a-4g, 5a-5f and 6a-6e were synthesized by reaction of 1-(alpha-Carbomethoxy-beta-aminothiocrotonoyl)-aryl/aroyl amines (3) with 3-(bromoacetyl)coumarin, 1,4-dibromodiacetyl and chloroacetone respectively. The compound 3 were synthesized by nucleophilic addition of aryl/aroylisothiocyanate and enamine (2). The(More)
We have investigated antihyperlipidaemic effect of swertiamarin (50 mg/kg, oral once) isolated from the perennial herb Enicostemma littorale Blume in poloxamer 407 (P-407)-induced hyperlipidaemic rats. Rats were made hyperlipidaemic by intraperitoneal administration of P-407 (400 mg/kg). Serum lipid levels such as total cholesterol, triglycerides and(More)
Small molecule heterocycle is an integral part of new drug discovery in anti-inflammatory research. In our previous papers we reported the synthesis of thiophene analogs substituted at the fifth position with alpha-oximino propionic ester moiety and the fact that such new chemical entities exhibit anti-inflammatory activity in male/female Sprague-Dawley(More)
Compounds incorporating thiophene moiety, a pi excess five membered heterocycle, have attracted a great deal of research interest, owing to the therapeutic utility of the template as useful drug molecular scaffolding. We report the synthesis and pharmacological evaluation of thiophenes substituted with 4-methanesulfonyl benzoyl moiety at the fifth position(More)
A series of 2-amino-5-benzoyl-4-phenylthiazole derivatives was investigated in radioligand binding studies at adenosine receptor (AdoR) subtypes with the goal to obtain potent and A(1)-selective antagonists. Acylation of the 2-amino group was found to be crucial for high A(1) affinity. The best compound of the present series was(More)
Compounds incorporating a thiophene moiety, a pi excess five membered heterocycle, have attracted a great deal of research interest owing to the therapeutic utility of the template as useful drug molecular scaffolding. Recently we reported the anti-inflammatory activity profile exhibited by two thiophene analogs, AP84 and AP82 in acute and chronic models of(More)
