A series of novel 9-substituted beta-carboline derivatives was synthesized from harmine and l-tryptophan, respectively. Cytotoxic activities of these compounds in vitro were investigated. The results showed that most compounds of 9-substituted beta-carboline derivatives had more remarkable cytotoxic activities in vitro than their corresponding parent compounds. Acute toxicities and antitumor effects
分别从甜蜜素和色氨酸合成了一系列新颖的9-取代的β-咔啉衍生物。研究了这些化合物在体外的细胞毒活性。结果表明,大多数9-取代的β-咔啉衍生物的化合物在体外具有比其相应母体化合物更显着的细胞毒活性。还检查了选定的β-咔啉衍生物在小鼠中的急性毒性和抗肿瘤作用。结果表明,位置9处的短烷基或苄基取代基显着提高了抗肿瘤活性,位置3处的乙氧羰基或羧基取代基显着降低了这些β-咔啉衍生物的急性毒性和神经毒性。而且,与其他化合物相比,在第3位具有烷氧基羰基或羧基取代基且在第9位具有短烷基或苄基取代基的化合物均表现出更显着的抗肿瘤活性以及较低的急性毒性和神经毒性。发现分别在第9位和第3位具有正丁基和羧基取代基的化合物8c具有最高的抗肿瘤作用和最低的急性毒性和神经毒性。这些数据表明:(1)β-咔啉衍生物第9位和第3位的适当取代基可能在确定其增强的抗肿瘤活性以及降低的急性毒性和神经毒性作用方面起着至关重要的作用;
