Indoleamine 2,3‐dioxygenase 1 (IDO1) has emerged as a key target for cancer therapy, as IDO1 plays a critical role in the capacity of tumor cells to evade the immune system. The pyrrolopiperazinone alkaloid longamide B and its derivatives were identified as novel IDO1 inhibitors based on docking studies and small library synthesis. The thioamide derivative showed higher IDO1 inhibitory activity than
吲哚胺2,3-二加氧酶1(IDO1)已成为癌症治疗的主要靶标,因为IDO1在肿瘤细胞逃避免疫系统的能力中起着至关重要的作用。根据对接研究和小文库合成,吡咯并哌嗪酮生物碱长酰胺B及其衍生物被鉴定为新型IDO1抑制剂。硫酰胺衍生物显示出比长酰胺B高的IDO1抑制活性,并显示出与代表性IDO1抑制剂1-甲基色氨酸相似的活性。这些结果表明,长酰胺B的吡咯并哌嗪酮支架可用于IDO1抑制剂的开发。
