synthesized and evaluated for their antitumor activity against eight human cancer cell lines. The β-carboline N-(substituted-benzylidene)carbohydrazides showed, in general, a greater antitumor activity than their N-(alkylidene)carbohydrazide analogues. The N9-methylation of β-carboline N-(substituted-benzylidene) carbohydrazides resulted in a decrease of antitumor activity. Among compounds tested, the b
合成了一系列在C-3处带有取代的碳酰肼部分的β-咔啉衍生物,并评估了其对八种人类癌细胞系的抗肿瘤活性。通常,β-咔啉N-(取代的亚苄基)碳酰肼显示出比其N-(亚烷基)碳酰肼类似物更大的抗肿瘤活性。β-咔啉N-(取代的亚苄基)碳酰肼的N 9甲基化导致抗肿瘤活性降低。在所测试的化合物中,苄基碳酰肼3,4,11,13,16,21和22是最活跃的,具有IC对于八种肿瘤细胞系中的六种,有50种小于10μM。衍生物4对所有测试的细胞系表现出最显着的活性,对肾脏(786-0)细胞系具有显着的细胞毒性(IC 50 = 0.04μM)。在Ehrlich实体癌测定中测定化合物4的体内抗肿瘤活性。
