thiazolidine-4-carboxylic acid derivatives were synthesized and evaluated for their ability to inhibit neuraminidase (NA) of influenza A virus. All the compounds were synthesized in good yields starting from commercially available l-cysteine hydrochloride using a suitable synthetic strategy. These compounds showed moderate inhibitory activity against influenza A neuraminidase. The most potent compound of
合成了一系列噻唑烷-4-羧酸衍生物,并评估了它们抑制甲型流感病毒神经氨酸酶(NA)的能力。使用合适的合成策略,从市售的1-半胱氨酸盐酸盐开始以高收率合成所有化合物。这些化合物显示出对甲型流感神经氨酸酶的中等抑制活性。该系列中最有效的化合物是化合物4f(IC 50 = 0.14μM),其效力比奥司他韦低约七倍,可用于设计新颖的基于NA噻唑烷环显示出更高活性的NA流感抑制剂。
