X-ray, NMR, and SAR data, the N,O-diMeTyr5 unit of didemnin B was believed to be important for biological activity. To determine the importance of aromaticity and the role of the methoxy group in this unit, two analogs were synthesized in which the N,O-diMeTyr5 moiety was replaced with N-MeLeu and N-MePhe. Preliminary testing showed that the analogs retained antitumor activity and the ability to inhibit
基于来自X射线,NMR和SAR数据的信息,认为二氢蝶呤B的N,O -diMeTyr 5单元对于生物活性很重要。为了确定芳香性的重要性和甲氧基在该单元中的作用,合成了两个类似物,其中N,O- diMeTyr 5部分被N- MeLeu和N- MePhe取代。初步测试表明,该类似物在体外具有抗肿瘤活性和抑制蛋白质生物合成的能力。
