A new series of polysubstituted 1‐aryl‐2‐oxo‐1,2‐dihydropyridine‐3‐carbonitriles and pyrazolo[3,4‐b]pyridine‐5‐carbonitriles and pyrido[2,3‐d]pyrimidine‐6‐carbonitriles have been synthesized and tested for their antifibrotic activity. Among the tested compounds, compounds IIc and IVb exhibited higher antifibrotic activity than the standard pirfenidone PD with a reduction of the hydroxyproline level
新系列多取代的 1-aryl-2-oxo-1,2-dihydropyridine-3-carbonitriles 和 pyrazolo [3,4-b] pyridine-5-carbonitriles 和pyrido [2,3-d] pyrimidine-6-carbonitriles已经合成并测试了它们的抗纤维化活性。在测试的化合物中,化合物 IIc 和 IVb 表现出比标准吡非尼酮 PD 更高的抗纤维化活性,羟脯氨酸水平分别降低至 50 和 140 μmol/肺。然而,双环吡啶酮 VIIIb 显示出高死亡率。报告了详细的合成、光谱和生物学数据。
