Neuraminidase inhibitors can deter nascent viruses from infecting intact cells by preventing their release from host cells. Herein, a neuraminidase inhibitor 11b absent of basic moieties was discovered in the process of searching for inhibitors targeting 150 cavity. It exhibited potent inhibitions against wild-type neuraminidases from group 1 (H5N1 and H1N1) and group 2 (H7N9) subtypes with IC50 values
神经氨酸酶抑制剂可以阻止新生病毒从宿主细胞中释放,从而阻止新生病毒感染完整细胞。在此,在寻找靶向150腔的抑制剂的过程中发现了缺乏碱性部分的神经氨酸酶抑制剂11b。它显示出对第1组(H5N1和H1N1)和第2组(H7N9)亚型野生型神经氨酸酶的有效抑制作用,其IC 50值类似于奥司他韦羧酸盐。而且,11b显示对H5N1-H274Y和H1N1-H274Y突变神经氨酸酶的中等抑制,IC 50值分别为2075 nM和1382 nM,低于奥司他韦羧酸盐的值(6095 nM和4071 nM)。结果与公认的SAR不一致,SAR的基本部分是有效抑制剂必不可少的部分。
