potent and selective sulfone hydroxamate inhibitors SC‐76276, SC‐78080 (SD‐2590), and SC‐77964, potent MMP inhibitors have been designed and synthesized to append a boron‐rich carborane cluster by employing click chemistry to target tumor cells that are known to upregulate gelatinases. Docking against MMP‐2 suggests binding involving the hydroxamate zinc‐binding group, key H‐bonds by the sulfone moiety
基于先前报道的强效选择性砜异羟肟酸酯抑制剂 SC-76276、SC-78080 (SD-2590) 和 SC-77964,已经设计并合成了有效的 MMP 抑制剂,通过点击化学添加富硼碳硼烷簇靶向已知上调明胶酶的肿瘤细胞。与 MMP-2 对接表明结合涉及异羟肟酸锌结合基团、砜部分与肽骨架残基 Leu82 和 Leu83 的关键 H 键,以及与深 P1' 口袋的疏水相互作用。两种三唑区域异构体中更有效的一种的 IC 50与 MMP-2 相比为 3.7 nM,IC 50与 MMP-9 相比为 46 nM。
