Improved derivatives of mycophenolic acid (MPA) are necessary to reduce the frequency of adverse effects, this drug exerts in treated patients. In this study, MPA was coupled with N-(ω-hydroxyalkyl)-9-acridone-4-carboxamides or N-(ω-hydroxyalkyl)acridine-4-carboxamides to give respective ester conjugates upon Yamaguchi protocol. This esterification required protection of phenol group in MPA. Designed
麦考酚酸(MPA)的改良衍生物对于减少这种药物在治疗患者中产生的不良反应的发生率是必不可少的。在这项研究中,MPA与N-(ω-羟烷基)-9-ac啶酮-4-羧酰胺或N-(ω-羟烷基)ac啶-4-羧酰胺偶联后,根据Yamaguchi方案生成相应的酯共轭物。这种酯化作用需要保护MPA中的酚基。设计的结合物显示出比母体MPA更高的体外效价。cr啶衍生物比a啶酮类似物更具活性,MPA和杂环单元之间的烷基接头长度会影响所观察到的细胞毒性。衍生物2b,2d,3a,3b显示出最有希望的免疫抑制活性。
