以二乙烯基砜和丙烯腈为原料,通过1,3-偶极环加成反应合成了吡咯烷环4位带有亲电取代基的顺式-5-苯基脯氨酸酯。4-乙烯基磺酰基5-苯基脯氨酸抑制S。金黄色葡萄球菌分选酶SrtA通过酶Cys 184的修饰不可逆地被转化,并且可以用作开发抗菌剂和抗毒力剂的命中物。
cis-5-Phenyl prolinates with electrophilic substituents at the fourth position of a pyrrolidine ring were synthesized by 1,3-dipolar cycloaddition of arylimino esters with divinyl sulfone and acrylonitrile. 4-Vinylsulfonyl 5-phenyl prolinates inhibit S. aureus sortase SrtA irreversibly by modification of the enzyme Cys184 and could be used as hits for the development of antibacterials and antivirulence agents.
