A novel series of 4-aryl-3-cyano-2-(3-hydroxyphenyl)-6-morpholino-pyridines have been designed as potential phosphatidylinositol-3-kinase (PI3K) inhibitors. The compounds have been synthesized using the Guareschi reaction to prepare the key 4-aryl-3-cyano-2,6-dihydroxypyridine intermediate. A different selectivity according to the nature of the aryl group has been observed. Compound 9b is a selective inhibitor against the PI3Kα isoform, maintaining a good inhibitory activity. Docking studies were also performed in order to rationalize its profile of selectivity.
设计了一系列新型的4-芳基-3-氰基-2-(3-羟基苯基)-6-吗啉代吡啶作为潜在的磷脂酰肌醇-3-激酶(PI3K)抑制剂。通过Guareschi反应合成了关键的4-芳基-3-氰基-2,6-二羟基吡啶中间体。根据芳基基团的性质,观察到了不同的选择性。化合物9b是针对PI3Kα同工酶的选择性抑制剂,并保持良好的抑制活性。为了合理化其选择性特征,还进行了对接研究。
