A series of novel combretastatin A-4 (CA-4) thio derivatives containing different molecular cores, namely α-phenylcinnamic acids (core 1), (Z)-stilbenes (core 2), 4,5-disubstituted oxazoles (core 3), and 4,5-disubstituted N-methylimidazoles (core 4), as cis-restricted analogues were designed and synthesized. They were selected with the use of a parallel virtual screening protocol including the generation
一系列含有不同分子核心的新型康布雷他汀A-4(CA-4)硫代衍生物,分别为α-苯基肉桂酸(核心1),(Z)-对苯甲酸酯(核心2),4,5-二取代的恶唑(核心3)和4,5-二取代的N-甲基咪唑(核心4),如顺式-限制性类似物的设计和合成。通过使用并行虚拟筛选方案选择它们,包括基于精心设计的CA-4类似物合成方案生成虚拟组合库。评估所选化合物对一组六种人类癌细胞系(A431,HeLa,MCF7,MDA-MB-231,A549和SKOV)和两种人类非癌细胞系(HaCaT和CCD39Lu)的抗增殖活性。此外,估计了测试化合物对体外抑制微管蛋白聚合的作用。在本文研究的系列中,恶唑桥联的类似物表现出最有效的抗增殖活性。化合物23a,23e和23i与IC有效地抑制微管蛋白聚合50倍0.86,1.05,和0.85的值 μ分别男,。与其氧类似物23j相比,硫代衍生物23i对微管蛋白聚合反应的抑制作用提高了5
