  Antineoplastic Agents. 443. Synthesis of the Cancer Cell Growth Inhibitor Hydroxyphenstatin and Its Sodium Diphosphate Prodrug

  摘要：

  A structure-activity relationship (SAR) study of the South African willow tree (Combretum caffrum) antineoplastic constituent combretastatin A-4 (3b) led to the discovery of a potent cancer cell growth inhibitor designated phenstatin (5a). This benzophenone derivative of combretastatin A-4 showed remarkable antineoplastic activity, and the benzophenone derivative of combretastatin A-1 was therefore synthesized. The benzophenone, designated hydroxyphenstatin (6a), was synthesized by coupling of a protected bromobenzene and a benzaldehyde to give the benzhydrol with subsequent oxidation to the ketone. Hydroxyphenstatin was converted to the sodium phosphate prodrug (6e) by a dibenzyl phosphite phosphorylation and subsequent benzyl cleavage (6a --> 6d --> 6e). While hydroxyphenstatin (6a) was a potent inhibitor of tubulin polymerization with activity comparable to that of combretastatin A-1 (3a), the phosphorylated derivative (6e) was inactive.

  The benzophenone derivative of combretastatin A-1, designated “hydroxyphenstatin”, was synthesized by compiling a protected bromobenzene and a benzaldehyde to form a benzhydrol which was subsequently oxidized to the ketone. Hydroxyphenstatin was converted to a sodium phosphate prodrug by dibenzyl phosphite phosphorylation and subsequent benzyl cleavage: Hydroxyphenstatin and the prodrugs thereof were found to be a potent inhibitor of tubulin polymerization and to demonstrate surprisingly effective anti neoplastic activity against a series of human cancer cells and murine P388 lymphocytic leukemia cells.

  将康柏乙烯A-1的苯甲酮衍生物命名为“羟基苯基苯甲酮”，通过组合保护溴苯和苯甲醛合成苯并醇，随后氧化为酮。通过二苯基磷酸酯磷酸化和随后的苄基裂解，将羟基苯基苯甲酮转化为磷酸钠前药。发现羟基苯基苯甲酮及其前药是强效的微管聚合抑制剂，并对一系列人类癌细胞和小鼠P388淋巴细胞白血病细胞表现出惊人的有效抗肿瘤活性。
