Structure Guided Optimization, in Vitro Activity, and in Vivo Activity of Pan-PIM Kinase Inhibitors
摘要:
Proviral insertion of Moloney virus (PIM) 1, 2, and 3 kinases are serine/threonine kinases that normally function in survival and proliferation of hematopoietic cells. As high expression of PIM1, 2, and 3 is frequently observed in many human malignancies, including multiple myeloma, non Hodgkins lymphoma, and myeloid leukemias, there is interest in determining whether selective PIM1 inhibition can improve outcomes of these human cancers. Herein, we describe our efforts toward this goal. The structure guided optimization of a singleton high throughput screening hit in which the potency against all three PIM isoforms was increased >10,000 fold to yield compounds with pan PIM K(i)s < 10 pM, nanomolar cellular potency, and in vivo activity in an acute myeloid leukemia Pun dependent tumor model is described.
