Nitrile-type inhibitors are known to interact with cysteine proteases in a covalent-reversible manner. The chemotype of 3-cyano-3-aza-β-amino acid derivatives was designed in which the N-cyano group is centrally arranged in the molecule to allow for interactions with the nonprimed and primed binding regions of the target enzymes. These compounds were evaluated as inhibitors of the human cysteine cathepsins K, S, B, and L. They exhibited slow-binding behavior and were found to be exceptionally potent, in particular toward cathepsin K, with second-order rate constants up to 52 900 × 10(3) M(-1) s(-1).
已知腈类抑制剂以共价可逆的方式与半胱氨酸蛋白酶相互作用。设计了3-氰基-3-氮杂-β-氨基酸衍生物的化学类型,其中N-氰基位于分子中心,以便与靶酶的非引发和引发结合区域相互作用。评估了这些化合物作为人半胱氨酸组织蛋白酶K、S、B和L的抑制剂。它们表现出慢结合行为,并且发现具有异常高的活性,特别是对组织蛋白酶K,二级速率常数高达52 900 × 10(3) M(-1) s(-1)。
