Colony-stimulating factor-1 receptor (CSF1R) is implicated in tumor-associated macrophage (TAM) repolarization and has emerged as a promising target for cancer immunotherapy. Herein, we describe the discovery of orally active and selective CSF1R inhibitors by property-driven optimization of BPR1K871 (9), our clinical multitargeting kinase inhibitor. Molecular docking revealed an additional nonclassical hydrogen-bonding (NCHB) interaction between the unique 7-aminoquinazoline scaffold and the CSF1R hinge region, contributing to CSF1R potency enhancement. Structural studies of CSF1R and Aurora kinase B (AURB) demonstrated the differences in their back pockets, which inspired the use of a chain extension strategy to diminish the AURA/B activities. A lead compound BPR1R024 (12) exhibited potent CSF1R activity (IC50 = 0.53 nM) and specifically inhibited protumor M2-like macrophage survival with a minimal effect on antitumor M1-like macrophage growth. In vivo, oral administration of 12 mesylate delayed the MC38 murine colon tumor growth and reversed the immunosuppressive tumor microenvironment with the increased M1/M2 ratio.

RAF kinase plays a critical role in the RAF-MEK-ERK signaling pathway and inhibitors of RAF could be of use for the treatment of various cancer types. We have designed potent RAF-1 inhibitors bearing novel bicyclic heterocycles as key structural elements for the interaction with the hinge region. In both series exploration of the SAR was focussed on the substitution of the phenyl ring, which binds to the induced fit pocket. Overall, it was confirmed that incorporation of lipophilic substituents was needed for potent Raf inhibition and a number of potent analogues were obtained.
