3,5‐Disubstituted tetrahydro‐2H‐1,3,5‐thiadiazine‐2‐thione (THTT) derivatives; 4a–g were prepared and found to be a promising prodrug approach for peptide drugs. The pH profile for their degradation in aqueous buffer solutions was determined using HPLC technique and accounted for, in terms of specific base‐catalyzed reactions. All of the compounds however, showed high acid‐stability. Enzymatic (human
3,5-二取代四氢-2H-1,3,5-噻二嗪-2-硫酮(THTT)衍生物;制备了 4a-g 并发现它是一种有前途的肽药物前药方法。它们在缓冲水溶液中降解的 pH 曲线是使用 HPLC 技术确定的,并根据特定的碱催化反应进行计算。然而,所有化合物都显示出高酸稳定性。不同衍生物的酶促(人血清)水解提供了有利的 t1/2 范围,该特性允许控制药物作用的起效和持续时间。
