PIM1 and plasma cell myeloma: Compound 22 m, a sub‐nanomolar inhibitor of the pim‐1 and pim‐2 isoforms (IC50 values of 0.024 nM and 0.095 nM, respectively), effectively inhibited the phosphorylation of BAD in KMS‐12‐BM, a cell line that expresses high levels of all pim isoforms, to regulate myeloma cell proliferation and apoptosis.83
