The metabolites of (+/-)-5(-)[p(-)[2-(5-ethyl-2- pyridyl)ethoxy]benzyl]-2,4-thiazolidinedione (1, pioglitazone), which is a representative insulin-sensitizing agent, were synthesized to confirm their structures and for studies of their pharmacological properties. Of the metabolites identified, a compound hydroxylated at the 2-position of the ethoxy chain (3) and compounds oxygenated at the ethyl side
(+/-)-5(-)[p(-)[2-(5-乙基-2-吡啶基)乙氧基]苄基] -2,4-噻唑烷二酮(1,吡格列酮)的代谢物合成胰岛素增敏剂以确认其结构并研究其药理性质。在鉴定出的代谢物中,虽然效价略低,但发现在乙氧基链的2位羟基化的化合物(3)和在与吡啶环相连的乙基侧链的羟基化的化合物(4,5)上具有活性。比母体化合物
