Replacement of pyrazol-3-yl amine hinge binder with thiazol-2-yl amine: Discovery of potent and selective JAK2 inhibitors.
Thiazol-2-yl amine was identified as an isosteric replacement for pyrazol-3-yl amine during our efforts to identify potent and selective JAK2 inhibitors. The rationale, synthesis and biological evaluation of several analogs is reported, along with the in vivo evaluation of the lead compounds.
