As a new type of mecillinam prodrug, mecillinam (5-substituted 2-oxo-1, 3-dioxol-4-yl) methyl esters were prepared. These esters were found to produce at least 4-fold higher mecillinam levels in blood than mecillinam itself after oral administration to mice. Mecillinam (5-methyl-2-oxo-1, 3-dioxol-4-yl) methyl ester hydrochloride was hygroscopic, but its L-tartrate was not.
作为一种新型甲氧西林原药,我们制备了甲氧西林(5-取代的 2-氧代-1,3-二氧戊环-4-基)甲酯。研究发现,小鼠口服这些酯类药物后,血液中的美西林含量至少是美西林本身的 4 倍。美西林(5-甲基-2-氧代-1, 3-二氧戊环-4-基)甲酯盐酸盐具有吸湿性,但其 L-酒石酸盐不具有吸湿性。
