A series of 3(R)-aminopyrrolidine derivatives were designed and synthesized for JAK1-selective inhibitors through the modification of tofacitinib’s core structure, (3R,4R)-3-amino-4-methylpiperidine. From the new core structures, we selected (R)-N-methyl-N-(pyrrolidin-3-yl)-7H-pyrrolo[2,3-d]pyrimidin-4-amine as a scaffold for further SAR studies. From biochemical enzyme assays and liver microsomal
通过修饰托法替尼的核心结构(3 R,4 R)-3-氨基-4-甲基哌啶,设计并合成了一系列3(R)-氨基吡咯烷衍生物用于JAK1选择性抑制剂。从新的芯结构,我们选择([R )- ñ甲基ñ - (吡咯烷-3-基)-7- ħ吡咯并[2,3- d ]嘧啶-4-胺作为进一步的SAR研究的支架。通过生化酶测定和肝微粒体稳定性测试,(R)-3-(3-(甲基(7 H-吡咯并[2,3- d ]嘧啶-4-基)氨基)吡咯烷-1-基)-3-氧丙烷丙烷(6选择通过口服给药进行进一步的体内测试。化合物6显示相比,托法替尼的用于JAK1改善的选择性(IC 50 11,2.4×10 2,2.8×10 3和1.1×10 2 纳米的JAK1,JAK2,JAK3和TYK2,分别地)。在CIA和AIA模型测试中,化合物6的功效与托法替尼柠檬酸盐相似。
