Kahalalide F (KF) and the regioisomer isoKF are novel anticancer drugs of marine origin and currently under clinical investigation. Here we report the synthesis of two new KF analogs with significant in vitro and in vivo antifungal and antitumor activities. The primary amine hydrogen of ornithine in KF has been replaced with 4-fluoro-3-methylbenzyl and morpholin-4-yl-benzyl via reductive N-alkylation. The TGI of these analogs using the NCI-60 cell line screening revealed promising results when compared to paclitaxel. The result of in vivo hollow fiber and animal toxicity assays are presented.
Kahalalide F (KF) 和其立体异构体 isoKF 是新型海洋来源抗癌药物,目前正在进行临床研究。本文报道了两种新型 KF 类似物的合成,它们具有显著的体外和体内抗真菌和抗肿瘤活性。通过还原 N-烷基化,KF 中鸟氨酸的仲胺氢被 4-氟-3-甲基苄基和吗啉-4-基苄基取代。与紫杉醇相比,这些类似物在 NCI-60 细胞系筛选中的 TGI 显示出有希望的结果。本文还介绍了体内中空纤维和动物毒性试验的结果。
