Synthesis, preliminary structure–activity relationships, and in vitro biological evaluation of 6-aryl-3-amino-thieno[2,3-b]pyridine derivatives as potential anti-inflammatory agents
摘要:
In our previous study, a series of 6-aryl-3-amino-thieno[2,3-b]pyridine derivatives exhibited potent anti-proliferative activities and an unique hepatocellular carcinoma (HCC)-specific anticancer activity was also observed. In further anti-inflammatory research, thienopyridine derivative 1a showed potent inhibition of nitric oxide (NO) production. So a series of thienopyridine analogues of 1a were synthesized and evaluated for anti-inflammatory activities. The structure-activity relationships (SARs) revealed that the most potent analogues 1f and 1o were identified as potent inhibitors of NO production with IC50 values of 3.30 and 3.24 mu M, respectively. These results suggest that these 6-aryl-3-amino-thieno[2,3-b]pyridine derivatives might potentially constitute a novel class of anti-inflammatory agents, which require further studies.

cyanoacetamide, cyanothioacetamide and 3-aminopyrazols with sodium salt of 3-hydroxy-1-(2-naphthyl)prop-2-en-1-one gives pyridin-2-one, pyridin-2(1H)-thione, and pyrazolo[1,5-a]pyrimidine derivatives. These derivatives showed potent anti-tumor cytotoxic activity in vitro using different human cancer cell lines.
氰基乙酰胺,氰基硫代乙酰胺和3-氨基吡唑与3-羟基-1-(2-萘基)丙-2-烯-1-酮的钠盐进行环缩合可得到吡啶-2-酮,吡啶-2(1 H)-硫酮,和吡唑并[1,5- a ]嘧啶衍生物。这些衍生物在体外使用不同的人类癌细胞系显示出有效的抗肿瘤细胞毒活性。
