A newly discovered antineoplastic compound denominated “phenstatin” is herein described as are synthetic methods for producing phenstatin and the active prodrug thereof. Phenstatin was converted to the sodium phosphate prodrug (3d) by a dibenzylphosphite phosphorylation and subsequent hydrogenolysis sequence 3b→3c→3d. Phenstatin (3b) was found to be a potent inhibitor of tubulin polymerization and the binding of colchicine to tubulin comparable to combretastatin A-4 (1b).
一种新发现的抗肿瘤化合物被命名为“苯基史达汀”,本文描述了生产苯基史达汀及其活性前药的合成方法。苯基史达汀通过
二苯基磷酸酯
磷酸化和随后的氢解序列3b→3c→3d 转化为
磷酸钠前药(3d)。发现苯基史达汀(3b)是一种有效的微管聚合
抑制剂,与考尔地西汀结合到微管上的能力与康伯雷司汀 A-4(1b)相当。
