A series of twenty-six carbamates derived from aminocombretastatin A-4 (AmCA-4) were synthesized and evaluated for their capacity to affect cell proliferation, tubulin polymerization, mitotic cell arrest, microtubule network organization, apoptosis and endothelial tubular structures in vitro. The anti-proliferative activity of the synthetic carbamates was measured on several human tumor cell lines
合成了一系列来自氨基combretastatin A-4(AmCA-4)的26种氨基甲酸酯,并评估了它们在体外影响细胞增殖,微管蛋白聚合,有丝分裂细胞停滞,微管网络组织,凋亡和内皮小管结构的能力。在几种人类肿瘤细胞系(即HT-29,MCF-7,HeLa,A-549,MDA-MB-231,HL-60)以及内皮细胞上测量了合成氨基甲酸酯的抗增殖活性HMEC-1细胞系和非肿瘤细胞HEK-293细胞。这些化合物在纳摩尔范围内显示出抗增殖活性,从而远远超过了康普他汀A-4(CA-4)的活性,在某些情况下还超过了AmCA-4的活性。活性最高的化合物被证明是在苯环的间位带有氯,溴或甲氧基的氨基甲酸酯。此外,所有氨基甲酸酯通过与微管蛋白中的秋水仙碱结合位点相互作用,以类似于CA-4和AmCA-4的方式抑制体外微管蛋白聚合。如在A549人肺癌细胞中评估的,合成的氨基甲酸酯被证明与AmCA-4一样具有活性,可
