reported as inhibitor of the dengue protease with potency in the low-micromolar range. In the present study, this lead structure was modified with the intent to explore structure-activity relationships and obtain compounds with increased drug-likeness. Substitutions of the guanidine moieties, the aromatic rings, and the ester with other functionalities were evaluated. All changes were accompanied by
在登革热和西尼罗河病毒的复制中至关重要的黄病毒丝氨酸蛋白酶抑制剂在过去几年中引起了广泛关注。先前已经报道了二元4-胍基苯甲酸酯作为登革蛋白酶的抑制剂,其效力在低微摩尔范围内。在本研究中,对这种先导结构进行了修饰,目的是探索结构与活性之间的关系并获得具有增加的药物相似性的化合物。评价了胍基部分,芳环和具有其他官能团的酯的取代。所有变化都伴随着抑制作用的丧失,表明4-胍基苯甲酸酯支架是该化合物类别的必要元素。
