In this study, a series of novel hydroxyamidine derivatives were identified as potent and selective IDO1 inhibitors by structure-based drug design. Among them, compounds 13–15 and 18 exhibited favorable enzymatic and cellular activities. Compound 18 showed improved bioavailability in mouse, rat, and dog (F% = 44%, 58.8%, 102.1%, respectively). With reasonable in vivo pharmacokinetic properties, compound
在这项研究中,通过基于结构的药物设计,一系列新型羟基脒衍生物被鉴定为有效和选择性的 IDO1 抑制剂。其中,化合物13-15和18表现出良好的酶和细胞活性。化合物18在小鼠、大鼠和狗中显示出改善的生物利用度(分别为 F% = 44%、58.8%、102.1%)。化合物18具有合理的体内药代动力学特性,在转基因 MC38 异种移植小鼠模型中进行了进一步评估。化合物18与PD-1单克隆抗体的组合显示出协同抗肿瘤作用。这些数据表明化合物18作为一种潜在的癌症免疫治疗剂,应该值得进一步研究。
