rhinovirus (HRV) 3C protease (3CP) inhibitors are described. These compounds are comprised of a peptidomimetic binding determinant and an ethyl propenoate Michael acceptor moiety which forms an irreversible covalent adduct with the active site cysteine residue of the 3C enzyme. The ketomethylene-containing inhibitors typically display slightly reduced 3CP inhibition activity relative to the corresponding
描述了各种含酮亚甲基的人鼻病毒(HRV)3C蛋白酶(3CP)抑制剂的基于结构的设计,化学合成和生物学评估。这些化合物由拟肽结合决定簇和丙酸乙酯迈克尔受体部分组成,其与3C酶的活性位点半胱氨酸残基形成不可逆的共价加合物。相对于相应的肽衍生的分子,含酮亚甲基的抑制剂通常显示出略微降低的3CP抑制活性,但它们也显示出显着改善的抗病毒特性。已显示对含酮亚甲基化合物的优化可提供几种高活性3C蛋白酶抑制剂,它们可作为有效的抗鼻病毒药物(EC90 = <1 microM),对抗细胞培养中的多种病毒血清型。
