Comment: PF-956980 is an ATP-competitive, reversible pan-JAK inhibitor [1]. It is a useful commercially available JAK inhibitor tool. In addition to being an inhibitor of kinase activity, it is also reported to dose- and time-dependently reduce levels of JAK2/3 proteins (but not JAK1, as determined by Western blot) in human PBMCs, perhaps via modulating JAK2/3 synthesis [2]. This latter activity seems to be unique to PF-956980, as there are no published reports of depletion of JAK isozymes by any of the other JAK inhibitors (such as tofacitinib).
