AbstractA series of thiazolo[4,5-b]pyridin-2(3H)-one derivatives were obtained via [3 + 3]-cyclization of 4-amino-5H-thiazol-2-one and α,β-unsaturated ketones or α-ketoacids. The structures of newly synthesized compounds were established by spectral data and a single-crystal X-ray diffraction analysis. Target compounds were screened for their anticancer activity according to US NCI protocols and moderate
摘要通过4-氨基-5 H-噻唑-2-酮和α,β-不饱和的[3 + 3]-环化获得一系列噻唑并[4,5- b ]吡啶-2(3 H)-one衍生物酮或α-酮酸。通过光谱数据和单晶X射线衍射分析来建立新合成的化合物的结构。根据US NCI方案筛选目标化合物的抗癌活性,并确认了对测试细胞系的中等抑制活性。5-苯基-7-(吡啶-3-基)-3 H-噻唑并[4,5 - b ]吡啶-2-一(3)和2-氧代-7-噻吩-2-基-2,3-二氢噻唑并[4,5 - b ]吡啶-5-羧酸(12筛选了它们对HepG2和Balb / c 3T3细胞的细胞毒性作用,使用MTT,NRU和TPC分析显示了令人鼓舞的结果。 图形概要
