To develop non-prodrugs of taxoids with satisfactory stability in vivo, high water-solubility, and potent antitumor activity, we prepared several 10-O-sec-aminoethyl decetaxel analogs (3) and evaluated their cytotoxicity against mouse leukemia and human tumor cell lines, microtubule disassembly-inhibitory activity, and water-solubility. These analogs were synthesized from the 10-O-allyl baccatin derivatives (5a-c) using the β-lactam synthon method. Among these analogs, the 10-O-(2-morpholinoethyl) (18, 21) and 10-O-(2-thiomorpholinoethyl) (19, 24) analogs exhibited cytotoxicity comparable or superior to that of docetaxel (2). In addition, the methanesulfonic acid salt (18a) had a high water-solubility.
为了开发出具有令人满意的体内稳定性、高水溶性和强效抗肿瘤活性的类固醇非原药,我们制备了几种 10-O-sec-aminoethyl decetaxel 类似物(3),并评估了它们对小鼠白血病和人类肿瘤细胞系的细胞毒性、微管解体抑制活性和水溶性。这些类似物是用β-内酰胺合成法由 10-O- 烯丙基巴卡丁衍生物(5a-c)合成的。在这些类似物中,10-O-(2-吗啉基乙基)(18、21)和 10-O-(2-硫代吗啉基乙基)(19、24)类似物的细胞毒性与多西他赛(2)相当,甚至更强。此外,甲磺酸盐(18a)具有很高的水溶性。
