Zerumbonoquinone 10 and zerumbonaminone 11 have been designed to release toxic moieties selectively and preferentially under reductive conditions. These compounds were synthesized by coupling the quinone delivery system with zerumbone alcohol 8 and amine 9. All compounds were evaluated for cytotoxicity against KB (non reductase overexpressing cells), NCI-H187 and MCF-7 (reductase overexpressing cells) and normal cells (Vero cells). Bioreductive compounds 10 and 11 were found to act as bioreductive anticancer agents exhibiting less cytotoxicity than the parents 8 and 9 in KB cells with good stability, and were partially bioreductively active against MCF-7 and NCI-H187 cells.
零姆伯诺醌10和零姆
伯胺醌11已被设计在还原条件下选择性和优先释放有毒基团。这些化合物是通过将醌传递系统与零姆酮醇8和胺9结合合成的。所有化合物都针对KB(非还原酶过表达细胞)、NCI-H187和MCF-7(还原酶过表达细胞)以及正常细胞(Vero细胞)进行了细胞毒性评估。生化还原化合物10和11被发现是生化还原抗癌剂,与它们的母体化合物8和9相比,在KB细胞中表现出较少的细胞毒性,并且稳定性良好,对MCF-7和NCI-H187细胞有一定的生化还原活性。
