The present invention relates to methods of delivering pharmaceutical agents across membranes, including the skin layer or mucosal membranes of a patient. A pharmaceutical agent is covalently bonded to a chemical modifier, via a physiologically cleavable bond, such that the membrane transport and delivery of the agent is enhanced.

inability to penetrate the bacterial cell wall. Temporarily masking the phosphonate moiety as a prodrug has the potential to solve both issues. We report on the expansion of the acyloxymethyl and alkoxycarbonyloxymethyl phosphonate ester prodrug series of a fosmidomycin surrogate. Prodrug promoieties were designed based on electronic, lipophilic and siderophoric properties. This investigation led to the discovery
Fosmidomycin 是一种天然抗生素,具有有效的 IspC(DXR,1-脱氧-d-木酮糖-5-磷酸还原异构酶)抑制活性。这种酶催化非甲羟戊酸类异戊二烯生物合成途径的第一个关键步骤,这在大多数细菌(包括鲍曼不动杆菌和结核分枝杆菌)和顶复门寄生虫(包括疟原虫寄生虫)中必不可少。主要由于其高极性,磷米霉素表现出次优的药代动力学特性。此外,fosmidomycin 对鲍曼不动杆菌和结核分枝杆菌无活性由于其无法穿透细菌细胞壁。暂时将膦酸酯部分作为前药进行掩蔽有可能解决这两个问题。我们报告了磷胺霉素替代物的酰氧基甲基和烷氧基羰基氧基甲基膦酸酯前药系列的扩展。前药前体是根据电子、亲脂性和铁载体特性设计的。该研究导致发现了分别具有两位数纳摩尔和亚微摩尔 IC 50值的衍生物,用于对抗恶性疟原虫和鲍曼不动杆菌。
