A series of aryl nitrile-based ligands were prepared to investigate the effect of their electrophilicity on the affinity against the cysteine proteases rhodesain and human cathepsin L. Density functional theory calculations provided relative reactivities of the nitriles, enabling prediction of their biological affinity and cytotoxicity and a clear structure–activity relationship.
制备了一系列芳基腈基配体,以研究它们的亲电性对与胱氨酸蛋白酶罗德西亚酶和人类组织蛋白酶L的亲和力的影响。密度泛函理论计算提供了这些腈的相对反应性,使得能够预测它们的生物亲和力和细胞毒性,并明确了结构-活性关系。
