  Synthesis, antioxidant and anticholinesterase activities of novel coumarylthiazole derivatives

  摘要：

  A newly series of coumarylthiazole derivatives containing aryl urea/thiourea groups were synthesized and their inhibitory effects on acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE) were evaluated. The result showed that all the synthesized compounds exhibited inhibitory activity to both cholinesterases. Among them, 1-(4-(8-methoxy-2-oxo-2H-chromen-3-yl)thiazol-2-yl)-3-(4-chlorophenyl)thiourea (f8, IC50 = 4.58 mu M) was found to be the most active compound against AChE, and 1-(4-fluorophenyl)-3-(4-(6-nitro-2-oxo-2H-chromen-3-yl)thiazol-2-yl)urea (e31) exhibited the strongest inhibition against BuChE with IC50 value of 4.93 mu M, which was 3.5-fold more potent than that of galantamine. The selectivity of f8 and e31 were 2.64 and 0.04, respectively. In addition, the cupric reducing antioxidant capacities (CUPRAC) and ABTS cation radical scavenging abilities of the synthesized compounds were investigated for antioxidant activity. Among them, f8, f4 and f6 (IC50 = 1.64, 1.82 and 2.69 mu M, respectively) showed significantly better ABTS cation radical scavenging ability than standard quercetin (IC50 = 15.49 mu M).

• Synthesis and biological evaluation of some new coumarinyl thiazolopyrimidinones

  Two new series of coumarin linked, linear and angularly fused thiazolo-[3,2-a]-pyrimidinones have been synthesized from 3-bromoacetyl coumarins by azole and azine approaches. Regioisomeric 5H and 7H thiazolo-[3,2-a]-pyrimidinones have been clearly distinguished by their IR and UV fluorescence spectral data. All the compounds have been characterized by analytical and spectroscopic methods. Rate and yield enhancements have been achieved using microwave irradiation. The results of in vivo diuretic activity indicate that substituents on coumarin do not enhance the activity. In vitro antimicrobial activities have shown that the compounds are specifically active against Gram-positive but are inactive against Gram-negative bacterial strains. Moderate fungal activity was observed against Candida albicans and Penicillium chrysogenum and all the compounds were found to be inactive against Aspergillus niger.
