our effort to develop a prodrug approach that overcomes the solubility problem. The prodrug of BW-AQ-238, a potent anthraquinone analog, was made by esterification of the hydroxyl group with various natural amino acids. Cytotoxicity of these compounds toward Hela and EU-1 cells, their aqueous solubility, and the release kinetics of these prodrugs in buffer and in the presence of hydrolytic enzymes were
以前,我们报道了一类MDM2-MDM4二聚化抑制剂,它们在动物模型中上调p53并显示有效的抗癌活性。但是,水溶性阻碍了它们的进一步发展。在这里,我们描述了我们为克服溶解性问题而开发的前药方法的努力。BW-AQ-238(一种有效的蒽醌类似物)的前药是通过将羟基与各种天然氨基酸酯化而制得的。研究了这些化合物对Hela和EU-1细胞的细胞毒性,它们的水溶性以及在缓冲液中和存在水解酶的情况下这些前药的释放动力学。结果表明,氨基酸前药方法显着改善了水溶性,同时保持了母体药物的效力。
