A new generation of cyclic matrix metalloproteinase (MMP) inhibitors derived from dl-piperazinecarboxylic acid has been described. The design involves: incorporation of hydroxamic acid as the bidentate chelating agent for catalytic Zn(2+), placement of a sulfonamide group at the 1N-position of the piperazine ring to fill the S1' pocket of the enzyme, and finally attachment of diverse functional groups
已经描述了衍生自dl-哌嗪羧酸的新一代环状基质金属蛋白酶(MMP)抑制剂。设计包括:引入异羟肟酸作为催化性Zn(2+)的双齿螯合剂,在哌嗪环的1N位置放置一个磺酰胺基,以填充酶的S1'口袋,最后进行各种连接4N位置的官能团可优化效价和经口吸收。这三种元素的独特结合产生了对MMPs 1、3、9和13具有高亲和力的抑制剂20(分别为24、18、1.9和1.3 nM)。对于与20共结晶的MMP-3所获得的X射线晶体学数据,给出了有关键结合相互作用的详细信息,这些相互作用定义了基于哌嗪的MMP抑制剂的总体骨架几何形状。
