c-Fms-IN-6 is a potent inhibitor of c-FMS (IC50 ≤10 nM for unphosphorylated c-FMS) and also weakly inhibits unphosphorylated c-KIT and PDGFR (IC50: > 1 μM).
NAMPT inhibitor-linker 1, a drug-linker conjugate for ADC, integrates an NAMPT inhibitor (as a payload) with a linker. In the formulation of ADC-3, it pairs with an anti-c-Kit monoclonal antibody, demonstrating strong efficacy against c-Kit expressing cell lines, specifically GIST-T1 and NCI-H526, where it exhibits IC50 values of <3 pM and 9 pM, respectively.
Antitumor agent-70 (compound 8b) is a highly potent multi-targeted kinase inhibitor, 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]
