series of novel isoflavonoids were synthesized based on structural modifications of daidzein, an active ingredient of traditional Chinese medicine (TCM) and evaluated for their anti‐influenza activity, in vitro, against H1N1 Tamiflu‐resistant (H1N1 TR) virus in the MDCK cell line. Among them, 4‐oxo‐4H‐1‐benzopyran‐8‐carbaldehydes 11a–11g were most promising, and they demonstrated better activities and selectivities
基于中药(TCM)活性成分黄豆苷元的结构修饰合成了一系列新型异黄酮,并在体外评估了它们在MDCK细胞中对抗H1N1达菲耐药(H1N1 TR)病毒的抗流感活性线。其中,4-oxo-4H-1-benzopyran-8-carbaldehydes 11a-11g 是最有前途的,它们表现出与核苷类抗病毒剂利巴利文相比更好的活性和选择性。3-(4-Bromophenyl)-7-hydroxy-4-oxo-4H-1-benzopyran-8-carboxaldehyde (11c) 显示出最好的抑制活性 (EC50, 29.0 μM) 和选择性指数 (SI>10.3)。
