Abstract

Because of the increased use of alkaloids in general medical practice in recent years, it is of interest to determine genotoxic, mutagenic and recombinogenic response to different groups of alkaloids in prokaryotic and eucaryotic organisms. Reserpine, boldine and chelerythrine did not show genotoxicity response in the SOS-Chromotest whereas skimmianine showed genotoxicity in the presence of a metabolic activation mixture. Voacristine isolated from the leaves of Ervatamia coronaria shows in vivo cytostatic and mutagenic effects in Saccharomyces cerevisiae hapioids cells. The Rauwolfia alkaloid (reserpine) was not able to induce reverse mutation and recombinational mitotic events (crossing-over and gene conversion) in yeast diploid strain XS2316.

摘要

由于近年来生物碱在一般医学实践中的使用增加,因此确定原核生物和真核生物对不同组生物碱的遗传毒性、诱变和重组反应很有意义。利血平、波丹宁和白屈菜红碱在SOS-色测试中未显示遗传毒性反应,而士的宁宁在存在代谢活化混合物时显示出遗传毒性。从狗牙花叶子中分离出的沃克长春碱在酿酒酵母单倍体细胞中显示出体内细胞抑制和诱变作用。萝芙木生物碱(利血平)不能在酵母二倍体菌株XS2316中诱导回复突变和重组有丝分裂事件(交换和基因转换)。
