Discovery of 2-(4-Chloro-3-(trifluoromethyl)phenyl)- N-(4-((6,7-dimethoxyquinolin-4-yl)oxy)phenyl)acetamide (CHMFL-KIT-64) as a Novel Orally Available Potent Inhibitor against Broad-Spectrum Mutants of c-KIT Kinase for Gastrointestinal Stromal Tumors

Starting from our previously developed c-KIT kinase inhibitor CHMFL-KIT-8140, through a type II kinase inhibitor binding element hybrid design approach, we discovered a novel c-KIT kinase inhibitor compound 18 (CHMFL-KIT-64), which is potent against c-KIT wt and a broad spectrum of drug-resistant mutants with improved bioavailability. 18 exhibits single-digit nM potency against c-KIT kinase and c-KIT T670I mutants in the biochemical assay and displays great potencies against most of the gain-of-function mutations in the juxtamembrane domain, drug-resistant mutations in the ATP binding pocket (except V654A), and activation loops (except D816V). In addition, 18 exhibits a good in vivo pharmacokinetic (PK) profile in different species including mice, rats, and dogs. It also displays good in vivo antitumor efficacy in the c-KIT T670I, D820G, and Y823D mutant-mediated mice models as well as in the c-KIT wt patient primary cells which are known to be imatinib-resistant. The potent activity against a broad spectrum of clinically important c-KIT mutants combining the good in vivo PK/pharmacodynamic properties of 18 indicates that it might be a new potential therapeutic candidate for gastrointestinal stromal tumors.

The overexpression of AXL kinase has been described in many types of cancer. Due to its role in proliferation, survival, migration, and resistance, AXL represents a promising target in the treatment of the disease. In this study we present a novel compound family that successfully targets the AXL kinase. Through optimization and detailed SAR studies we developed low nanomolar inhibitors, and after further biological characterization we identified a potent AXL kinase inhibitor with favorable pharmacokinetic profile. The antitumor activity was determined in xenograft models, and the lead compounds reduced the tumor size by 40% with no observed toxicity as well as lung metastasis formation by 66% when compared to vehicle control.
