cytotoxicity against B16 melanoma cells. Amide, carbamate, urea, and thiourea congeners were prepared. The most potent derivatives found in this study are the docetaxel analog 13, the N-[(tert-amyloxy)carbonyl] analog 17, and the 3'-phenylurea and 3'-tert-butylurea derivatives 20 and 23. Six of these analogs were shown to be ca. 90 times more soluble in water than paclitaxel and ca. 4-5 times more water-soluble
由10-去乙酰基浆果赤霉素III和恶唑烷羧酸7合成酰紫杉醇的3'-(叔丁基)3'-去苯基类似物,然后酰化中间胺10和11。恶唑烷羧酸7分五个步骤制备,并从中总产率良好L-叔亮氨酸。合成了十二个类似物,并评估了它们刺激微管形成的体外能力以及针对B16黑色素瘤细胞的细胞毒性。制备了酰胺,氨基甲酸酯,尿素和硫脲同类物。在这项研究中发现的最有效的衍生物是多西他赛类似物13,N-[(叔戊氧基)羰基]类似物17、3'-苯基脲和3'-叔丁基脲衍生物20和23。其中六个类似物被证明是大约。在水中的溶解度比紫杉醇高约90倍。
