series of phosphate and ester-based prodrugs of anilinopyrazinone 1 (BMS-665053) containing either a methylene or an (acyloxy)alkoxy linker was prepared and evaluated in rat pharmacokinetic studies with the goal of improving the oral bioavailability of the parent (1). The prodrugs, in general, had improved aqueous solubility and oral bioavailability compared to 1. Prodrug 12, which contains an (acyloxy)alkoxy
制备了一系列含有亚甲基或(酰氧基)烷氧基连接基的苯并吡嗪酮1(BMS-665053)磷酸盐和酯基前药,并在大鼠药代动力学研究中进行了评估,目的是提高母体的口服生物利用度(1) 。与1相比,前药通常具有改善的水溶性和口服生物利用度。含有(酰氧基)烷氧基连接基的前药12相对于母体(1)具有最大的口服生物利用度改善,是母体的7倍。在大鼠药代动力学研究中增加(从5%到36%)。
