Using a dengue replicon cell line-based screening, we identified 3-(dimethylamino)propyl(3-((4-(4-fluorophenyl)-1-oxophthalazin-2(1H)-yl)methyl)phenyl)carbamate (10a) as a potent DENV-2 inhibitor, with an IC50 value of 0.64 μM. A series of novel phthalazinone derivatives based on hit 10a were synthesized and evaluated for their in vitro anti-DENV activity and cytotoxicity. The subsequent SAR study
使用基于登革热复制子细胞系的筛选,我们确定了3-(二甲基氨基)丙基(3-(((4-(4-氟苯基)-1-氧酞嗪-2(1H)-基)甲基)苯基)氨基甲酸酯(10a)作为有效的DENV-2抑制剂,IC 50值为0.64μM。合成了一系列基于命中10a的新型酞嗪酮衍生物,并对其体外抗-DENV活性和细胞毒性进行了评估。随后的SAR研究和优化导致发现最有前途的化合物14l,该化合物显示出强大的抗-DENV-2活性,对DENV-2 RNA复制的IC 50值低,为0.13μM,选择性高(SI = 89.2)。可接受的药代动力学资料。
