Design, synthesis, and pharmacological evaluation of N-(3-carbamoyl-1H-pyrazol-4-yl)-1,3-oxazole-4-carboxamide derivatives as interleukin-1 receptor-associated kinase 4 inhibitors with reduced potential for cytochrome P450 1A2 induction

molecule in Toll-like receptor/interleukin-1 receptor signaling and an attractive therapeutic target for a wide range of inflammatory and autoimmune diseases as well as cancers. In our search for novel IRAK4 inhibitors, we conducted structural modification of a thiazolecarboxamide derivative 1, a lead compound derived from high-throughput screening hits, to elucidate structure–activity relationship and improve
白细胞介素 1 受体相关激酶 4 (IRAK4) 是 Toll 样受体/白细胞介素 1 受体信号转导中的关键分子,也是多种炎症和自身免疫性疾病以及癌症的有吸引力的治疗靶点。在寻找新型 IRAK4 抑制剂的过程中,我们对噻唑甲酰胺衍生物1 (一种源自高通量筛选命中的先导化合物)进行了结构修饰,以阐明结构-活性关系并改善药物代谢和药代动力学 (DMPK) 特性。首先,将1的噻唑环转化为恶唑环,并在吡啶环的2位引入甲基,以减少细胞色素P450(CYP)抑制,得到16 。接下来,为了改善CYP1A2诱导特性而对16的吡唑环1位上的烷基取代基进行了修饰,结果表明支链烷基和类似的取代基如异丁基( 18 )和(氧杂环戊烷-3-基)甲基( 21 ),以及六元饱和杂环基团,例如oxan-4-基( 2 )、哌啶-4-基( 24、25 )和二氧噻吩-4-y( 26 ),可有效降低诱导电位。代表性化合物 AS2444697
