A southern Australian marine sponge, Trachycladus laevispirulifer, yielded the cytotoxic agents trachycladindoles AâG (1â7) as a selection of novel indole-2-carboxylic acids bearing a 2-amino-4,5-dihydroimidazole moiety. The trachycladindoles displayed promising selective cytotoxicity against a panel of human cancer cell lines and their structures were assigned on the basis of detailed spectroscopic analysis. Preliminary structure activity relationship (SAR) investigations by co-metabolite defined structural features key to the trachycladindole pharmacophore, highlighting an unusual bioactive molecular motif deserving of future investigation.
一种产自澳大利亚南部的海洋海绵Trachycladus laevispirulifer产生了细胞毒性物质trachycladindoles A-G(1-7),它们是带有2-氨基-4,5-二氢咪唑部分的新型吲哚-2-羧酸。trachycladindoles对一组人类癌细胞系显示出有前景的选择性细胞毒性,其结构是根据详细的光谱分析确定的。通过共代谢物进行的初步结构活性关系(SAR)研究确定了trachycladindole药效团的关键结构特征,突出了一个不寻常的生物活性分子基序,值得进一步研究。
