Based on (R)-N-methyl-N-(5-azaspiro?2.4]heptan-7-yl)-7H-pyrrolo?2, 3-d]pyrimidin-4-amine as a core scaffold, we identified (R)-3-(7-(methyl?7H-pyrrolo?2, 3-d]pyrimidin-4-yl)amino)-5-azaspiro?2.4]heptan-5- yl)-3-oxopropanenitrile [(R)-6c] as a JAK1 selective inhibitor. The structural design was based on the combination of tofacitinib's 7-deazapurine and 5-azaspiro?2.4]heptan-7-amine. Compound (R)-6c exhibited an IC50 value of 8.5 nM against JAK1 with a selectivity index of 48 over JAK2. To optimize (R)-6c as a lead compound, we performed in vitro ADME, hERG, kinase profiling, and pharmacokinetic tests. Mouse and rat in vivo studies verified that (R)-6c exhibited desired efficacies in CIA and AIA models.
