compounds share a common 7H‐pyrrolo[2,3‐d]pyrimidine hinge binding motif, and little is known about modifications tolerated at this heterocyclic core. In the current study, a library of tofacitinibbioisosteres was prepared and tested against JAK3. The compounds possessed the tofacitinib piperidinyl side chain, whereas the hinge binding motif was replaced by a variety of heterocycles mimicking its pharmacophore
