Famitinib (SHR1020) is a potent orally active multi-targeted kinaseinhibitor that effectively inhibits the activity of c-kit, VEGFR-2, and PDGFRβ with IC50 values of 2.3 nM, 4.7 nM, and 6.6 nM, respectively [1]. It demonstrates remarkable antitumor properties in human gastric cancer cells and xenografts, inducing apoptosis [2].
Amuvatinib hydrochloride (MP470 hydrochloride) is an orally bioavailable multi-targeted tyrosine kinaseinhibitor with potent activity against mutant c-Kit, PDGFRα, Flt3, c-Met and c-Ret and is also a DNA repair suppressor through suppression of DNA repai
Antitumor agent-70 (compound 8b) is a highly potent multi-targeted kinaseinhibitor, particularly targeting c-Kit. It demonstrates remarkable anti-tumor activity and the ability to induce cell apoptosis. This compound also exhibits strong inhibition of multiple myeloma, with an IC 50 value of 0.12 μM. Therefore, Antitumor agent-70 holds great potential as an effective therapy for combating cancer, especially in cases involving c-Kit. [1]
EGFR HER2 DHFR-IN-1 is a highly selective and potent anticancer compound specifically targeting MCF-7 breast cancer cells. It acts as a multi-inhibitor, targeting the EGFR HER2 kinase and DHFR enzymes, with IC50 values of 0.153 μM, 0.108 μM, and 0.291 μM, respectively. Its mechanism of action involves cell cycle arrest at the G1 S phase and induction of apoptosis in cells [1].
N-Desmethyl Regorafenib N-oxide, an active metabolite of the multi-kinaseinhibitor regorafenib, originates through the action of the cytochrome P450 (CYP) isoform CYP3A4. This compound demonstrates efficacy in vitro by inhibiting key enzymes such as VEGFR2, Tie2, c-Kit, and B-RAF, and it exhibits tumor growth inhibition in HT-29 and MDA-MB-231 mouse xenograft models at a dosage of 1 mg/kg.
