Described here are synthesis and biological evaluations of diversified groups of over 57 ertapenem prodrugs which include alkyl, methylenedioxy, carbonate, cyclic carbonate, carbamate esters, and esters containing active transport groups (e.g., carboxyl, amino acid, fatty acids, cholesterol) and macrocyclic lactones linking the two carboxyl groups. Many of the prodrugs were rapidly hydrolyzed in rat
这里描述的是超过57种厄他培南前药的多样化基团的合成和生物学评估,这些药物包括烷基,亚甲二氧基,碳酸酯,环状碳酸酯,氨基甲酸酯以及含有活性转运基团(例如羧基,氨基酸,脂肪酸,胆固醇)和大环酯的酯连接两个羧基的内酯。许多前药在大鼠血浆中迅速水解,但在人血浆中不迅速水解,并且在模拟胃肠道液中稳定。通过犬内注射给药,二乙酯前药显示出最佳的总吸收(> 30%),这可能会通过制剂开发而得到改善。然而,其缓慢水解为厄他培南的速率也导致大量循环单酯代谢物的存在,这构成了显着的开发挑战。
