in the asexual erythrocytic stage of development. These enzymes have been suggested as potential antimalarial drug targets. Herein we describe the development of peptidomimetic hydroxamates as PfA-M1 and PfA-M17 dual inhibitors. Most of the compounds described in this study display inhibition at sub-micromolar range against the recombinant PfA-M1 and PfA-M17. More importantly, compound 26 not only exhibits
导致疟疾的疟原虫对大多数使用中的抗疟药产生了抗药性,包括基于青蒿素的组合,这是对抗疟疾的最后一道防线。这需要发现新的靶点和开发新型抗疟药。恶性疟原虫丙氨肽酶 ( Pf A-M1) 和亮氨酰氨肽酶 ( Pf A-M17) 分别属于金属蛋白酶 M1 和 M17 家族,在无性红细胞发育阶段发挥关键作用。这些酶被认为是潜在的抗疟药物靶点。在此,我们将拟肽异羟肟酸盐的开发描述为Pf A-M1 和PfA-M17双重抑制剂。本研究中描述的大多数化合物对重组Pf A-M1 和Pf A-M17的抑制作用在亚微摩尔范围内。更重要的是,化合物26不仅表现出有效的疟疾氨肽酶抑制活性(Pf A-M1 K i = 0.11 ± 0.0002 µmol/L,Pf A-M17 K i = 0.05 ± 0.005 µmol/L),而且对疟疾氨肽酶具有显着的选择性。哺乳动物对应物 ( p APN K i = 17.24
