Profile and eliminate! Plasmepsins (PMs), aspartic proteases required for malaria‐parasite growth, are promising antimalarial targets. The in situ screening of PMs with probes formed from β‐hydroxyazides 1 and alkynes with a photo‐cross‐linking unit and a tetraethylrhodamine reporter led to the identification of the small‐molecule inhibitor 2, which inhibits all four food‐vacuole PMs and showed potent
剖析并消除!疟原虫生长所需的天冬氨酸蛋白酶-胃蛋白酶(PMs)是有希望的抗疟目标。用由β-羟基叠氮化物1和带有光交联单元的炔烃和四乙基罗丹明报告剂组成的探针对PMs进行原位筛选,从而鉴定出了小分子抑制剂2,该抑制剂可抑制所有四种食品-真空中的PMs,并显示出红细胞培养物中的有效抗疟疾活性。
