The most of potent neuraminidase inhibitors as zwitterions with poor lipophilicity suffered from the poor oral bioavailability. Herein, we describe a rational journey to discover a non-zwitterionic neuraminidase inhibitor 24a containing urea. It showed potent inhibitions against neuraminidases from group 1(H5N1 and H1N1) and group 2 (H3N2) subtypes and exhibited more strong inhibitory activities against
最有效的神经氨酸酶抑制剂,如两性离子,亲脂性差,口服生物利用度差。在本文中,我们描述了发现包含尿素的非两性离子神经氨酸酶抑制剂24a的合理旅程。它显示出对第1组(H5N1和H1N1)和第2组(H3N2)亚型的神经氨酸酶的有效抑制作用,并且比oseltamivir羧酸盐对H274Y突变体的神经氨酸酶表现出更强的抑制活性。与口服奥司他韦羧酸盐相比,无论是通过口服还是静脉注射,化合物24a在SD大鼠体内的药代动力学特性均得到改善。
