derivatives, rac-35, rac-36, rac-37, rac-38, rac-39 and rac-40, and assessed their cytotoxic activity against NSCLC cells and diploid fibroblasts. SAR studies revealed that the alcohol moiety at position 3 and its absolute R configuration both were essential for the tumor cell line selective activity while for its cytotoxic magnitude the alkyl chain length and branching were of less significance.
从加勒比海海绵Cribrochalina vasculum中分离出一系列 23 种直链和支链单乙炔脂质。其中 17 种化合物1-17是新的,而 6 种18-23是以前从同一海绵中表征的。测试了一些新的乙炔-3-羟基烷烃1、6、7、8、10在非小细胞肺癌 (NSCLC) 细胞中对 WI-38 正常二倍体肺成纤维细胞的选择性细胞毒性。化合物7表现出明显的肿瘤选择性活性,而化合物1和8在较低剂量和如图6和10所示,对NSCLC细胞完全没有活性。早期报道的一些乙炔-3-羟基烷烃(scal -18和23)在 NSCLC 细胞和/或其他肿瘤细胞类型中的选择性细胞毒性也被证实为19、20和22。为了进一步研究这组化合物的构效关系(SAR),我们合成了乙炔-3-羟基烷烃的几种衍生物rac - 18、scal- S - 18、R - 18、rac - 27、rac-32、R - 32、S - 32、rac -
