Analogues of the tetrahydroisoquinoline family of antitumor antibiotics, 3-epi-jorumycin (3) and 3-epi-renieramycin G (4), in addition to their respective parent natural products (-)-jorumycin (1) and (-)-renieramycin G (2) were evaluated against both human colon (HCT-116) and human lung (A549) cancer cell lines. (-)-Jorumycin (1) displayed potent growth inhibition with GI50 values in the low nanomolar range (1.9-24.3 nM), while compounds 2-4 were found to be substantially less cytotoxic (GI50 0.6-14.0 microM).
对四氢异喹啉类抗肿瘤抗生素的类似物3-表-约鲁霉素(3)和3-表-雷尼霉素G(4),以及它们各自的母体天然产物(-)-约鲁霉素(1)和(-)-雷尼霉素G(2),针对人结肠(HCT-116)和人肺(A549)癌细胞系进行了评估。(-)-约鲁霉素(1)表现出强效的生长抑制作用,其GI50值在低纳摩尔范围内(1.9 - 24.3 nM),而化合物2 - 4的细胞毒性则显著较低(GI50为0.6 - 14.0 microM)。
