Discovery of N-((1-(4-(3-(3-((6,7-Dimethoxyquinolin-3-yl)oxy)phenyl)ureido)-2-(trifluoromethyl)phenyl)piperidin-4-yl)methyl)propionamide (CHMFL-KIT-8140) as a Highly Potent Type II Inhibitor Capable of Inhibiting the T670I gatekeeper Mutant of cKIT Kinase

cKIT kinase inhibitors, e.g., imatinib, could induce drug-acquired mutations such as cKIT T670I that rendered drug resistance after chronic treatment. Through a type II kinase inhibitor design approach we discovered a highly potent type II cKIT kinase inhibitor compound 35 (CHMFL-KIT-8140), which potently inhibited both cKIT wt (IC50 = 33 nM) and cKIT gatekeeper T670I mutant (IC50 = 99 nM). Compound 35 displayed strong antiproliferative effect against GISTs cancer cell lines GIST-T1 (cKIT wt, GI50 = 4 nM) and GIST-5R (cKIT T670I, GI50 = 26 nM). In the cellular context it strongly inhibited c-KIT mediated signaling pathways and induced apoptosis. In the BaF3-TEL-cKIT-T670I isogenic cell inoculated xenograft mouse model, 35 exhibited dose dependent tumor growth suppression efficacy and 100 mg/kg dosage provided 47.7% tumor growth inhibition (TGI) without obvious toxicity. We believe compound 35 would be a good pharmacological tool for exploration of the cKIT-T670I mutant mediated pathology in GISTs.

Design, synthesis, and anticancer properties of isocorydine derivatives

Isocorydine (ICD), an aporphine alkaloid, is widely distributed in nature. Its ability to target side population (SP) cells found in human hepatocellular carcinoma (HCC) makes it and its derivative 8-amino-isocorydine (NICD) promising chemotherapeutic agents for the treatment of HCC. To improve the anticancer activity of isocorydine derivatives, twenty derivatives of NICD were designed and synthesized through chemical structure modifications of the aromatic amino group at C-8. The anti-proliferative activities of all synthesized compounds against human hepatocellular (HepG2), cervical (HeLa), and gastric (MGC-803) cancer cell lines were evaluated using an MTT assay. The results showed that all the synthetic compounds had some tumor cell growth inhibitory activity. The compound COM33 (24) was the most active with IC50 values under 10 μM (IC50 for HepG2 = 7.51 μM; IC50 for HeLa = 6.32 μM). FICD (12) and COM33 (24) were selected for further investigation of their in vitro and in vivo activities due to their relatively good antiproliferative properties. These two compounds significantly downregulated the expression of four key proteins (C-Myc, β-Catenin, CylinD1, and Ki67) in HepG2 cells. The tumor inhibition rate of COM33 (24) in vivo was 73.8% after a dose 100 mg/kg via intraperitoneal injection and the combined inhibition rate of COM33 (24) (50 mg/kg) with sorafenib (50 mg/kg) was 66.5%. The results indicated that these isocorydine derivatives could potentially be used as targeted chemotherapy agents or could be further developed in combination with conventional chemotherapy drugs to target cancer stem cells (CSCs) and epithelial-to-mesenchymal transition (EMT), the main therapeutic targets in HCC.
