In Vitro: CHMFL-ABL/KIT-155 (CHMFL-ABL-KIT-155) exhibits anti-proliferation activities in the BCR-ABL dependent CML cancer cell lines such as K562 (GI50: 0.027 µM), MEG-01 (GI50: 0.02 µM), and KU812 (GI50: 0.056 µM). It also potently inhibits the growth of c-KIT dependent GISTs cancer cell lines including GIST-T1 (GI50: 0.023 µM), GIST-882 (GI50: 0.095 µM) but not c-KIT independent GIST-48B (GI50: 3.96 µM) .
In Vivo: CHMFL-ABL/KIT-155 (CHMFL-ABL-KIT-155) (25-100 mg/kg; p.o.; once daily for 28 days) shows dose-dependent tumor progression suppression without apparent toxicity in female nu/nu mice bearing established K562 tumor xenografts.
