Abstract

The optimization of compounds from the 3-amido-4-anilinoquinolines series of CSF-1R kinase inhibitors is described. The series has excellent activity and kinase selectivity. Excellent physical properties and rodent PK profiles were achieved through the introduction of cyclic amines at the quinoline 6-position. Compounds with good activity in a mouse PD model measuring inhibition of pCSF-1R were identified.

    However, this compound is derived from a rather non-selective compound [17] and in addition, shows high non-specific binding in the brain. Among the multiple CSF-1R small molecule inhibitors currently in clinical development [17–22] is BLZ945, a highly potent and selective CSF-1R inhibitor (Ki = 1 nM, > 3200 fold selectivity over other kinases) [9]. This CSF-1R inhibitor demonstrated great efficacy in GBM mice, implicating good brain uptake.

    Compounds from the dimethoxy scaffold (166) have at best moderate aqueous solubility. Scott et al. [171] later found that the introduction of cyclic amines such as N-methylpiperazine at the 6-position (167) gives compounds with attractive physical properties and PK profiles, while retaining its potency. The transforming growth factor-β (TGF-β) type I receptor is a member of a large family of growth factors involved in the regulation of a diverse array of angiogenetic processes.

    The most potent NCI hit (25) illustrated IC50 value of 0.83 μM, while the drug hit isoxsuprine (33) yielded IC50 value of 2.9 μM and the herbicide hit foramsulfuran (34) gave anti-CDK1 IC50 of 3.6 μM. The aminoquinolines 25 and 31 are close to known kinase inhibitors (i.e., Pim-1 kinase [65] and CSF-1R kinase [66]). In fact, other aminoquinolines were also reported to possess potent anti-CDK1 activities [67].
