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.

New compounds, compositions and methods of inhibition of kinase activity associated with tumorigenesis in a human or animal subject are provided. In certain embodiments, the compounds and compositions are effective to inhibit the activity of at least one serine/threonine kinase or receptor tyrosine kinase. The new compounds and compositions may be used either alone or in combination with at least one additional agent for the treatment of a serine/threonine kinase- or receptor tyrosine kinase-mediated disorder, such as cancer.
