The receptor tyrosine kinase Axl plays important roles in promoting cancer progression, metastasis, and drug resistance and has been identified as a promising target for anticancer therapeutics. We used mol. modeling-assisted structural optimization starting with the low micromolar potency compound I to discover compound II, a highly potent and orally bioavailable Axl inhibitor. Selectivity profiling showed that II could inhibit the well-known oncogenic kinase Met with equal potency to its inhibition of Axl superfamily kinases.

G-protein coupled receptor kinase 2 (GRK2), which is upregulated in the failing heart, appears to play a critical role in heart failure (HF) progression in part because enhanced GRK2 activity promotes dysfunction of β-adrenergic signaling and myocyte death. An orally bioavailable GRK2 inhibitor could offer unique therapeutic outcomes that cannot be attained by current heart failure treatments that directly target GPCRs or angiotensin-converting enzyme. Herein, we describe the discovery of a potent, selective, and orally bioavailable GRK2 inhibitor, 8h, through high-throughput screening, hit-to-lead optimization, structure-based design, mol. modeling, synthesis, and biol. evaluation. In the cellular target engagement assays, 8h enhances isoproterenol-mediated cyclic adenosine 3′,5′-monophosphate (cAMP) production in HEK293 cells overexpressing GRK2. Compound 8h was further evaluated in a human stem cell-derived cardiomyocyte (HSC-CM) contractility assay and potentiated isoproterenol-induced beating rate in HSC-CMs.
