identification of an imidazopyridine class of potent and selective TYK2 inhibitors, exemplified by prototype 6, through constraint of the rotatable amide bond connecting the pyridine and aryl rings of compound 1. Further optimization led to generation of compound 30 that potently inhibits the TYK2 enzyme and the IL-23 pathway in cells, exhibits selectivity against cellular JAK2 activity, and has good pharmacokinetic
本文我们报道咪唑并吡啶类的有效和选择性抑制剂TYK2的,由原型例举的识别6,通过可旋转的酰胺键连接的化合物的吡啶和芳基环的约束1。进一步的优化导致了化合物30的产生,该化合物有效抑制细胞中的TYK2酶和IL-23途径,表现出对细胞JAK2活性的选择性,并具有良好的药代动力学特性。在小鼠体内,化合物30PK / PD模型以及咪喹莫特诱发的牛皮癣模型中,IL-17产生的剂量依赖性降低。在这种功效模型中,IL-17的降低伴随着耳厚度的降低,表明TYK2抑制作为牛皮癣患者的治疗方法的潜力。
