    Pim kinases are promising targets for the development of cancer therapeutics. Among the three Pim isoforms, Pim-2 is particularly important in multiple myeloma, yet is the most difficult to inhibit due to its high affinity for ATP. We identified compound 1 via high throughput screening. Using property-based drug design and co-crystal structures with Pim-1 kinase to guide analog design, we were able to improve potency against all three Pim isoforms including a significant 10,000-fold gain against Pim-2. Compound 17 is a novel lead with low picomolar potency on all three Pim kinase isoforms.
