upon selective conversion by purified DPPIV/CD26 and by soluble DPPIV/CD26 present in bovine, murine, and human serum. Vildagliptin, a specific inhibitor of DPPIV/CD26, was able to completely block the hydrolysis of the prodrugs in the presence of purified DPPIV/CD26 human, murine, and bovine serum. Several novel prodrugs showed remarkable increases in water solubility (up to more than 3 orders of magnitude)
我们提出基于二肽基肽酶IV(DPPIV / CD26)的前药方法在含羟基药物衍生物中的首次报道。特别是,我们将此策略应用于双环呋喃并嘧啶核苷类似物(BCNA)的高度亲脂性抗病毒药物家族,以改善其理化和药代动力学特性。我们的稳定性数据表明,通过纯化的DPPIV / CD26和存在于牛,鼠和人血清中的可溶性DPPIV / CD26的选择性转化,前药可有效释放母体BCNA药物。维达列汀,一种DPPIV / CD26的特异性抑制剂,在纯化的DPPIV / CD26人,鼠和牛血清的存在下能够完全阻断前药的水解。与难溶性母体药物相比,几种新颖的前药显示出水溶性的显着提高(最高超过3个数量级)。我们还证明了与小鼠母体药物相比,前药的口服生物利用度显着提高。
