Some novel valerolactam derivatives of 5(6)-substituted-(1H-benzimidazol-2-yl-amine) were constructed based on the union of two structural domains with anthelmintic activity. The tested hybrid compounds 7-9 exhibited greater activity using the Nippostrongylus brasiliensis physiology-based in vitro bioassay in comparison to commercial anthelmintic benzimidazoles. Moreover, the improved physicochemical properties of hybrid compounds compared with valerolactam domain allowed the penetration of parasite barriers, concurrently with an increased intraparasitary bioavailability.
基于具有驱虫活性的两个结构域的结合,构建了一些新颖的5(6)-取代-(1H-苯并咪唑-2-氨基)戊内酰胺衍生物。与市售的苯并咪唑类驱虫药相比,通过采用基于巴西钩口线虫生理学的体外生物测定试验,测试的杂化化合物7-9表现出更高的活性。此外,与戊内酰胺结构域相比,杂化化合物改善的物理化学性质使得它们能穿透寄生虫屏障,同时增加了寄生虫体内的生物利用度。
