FTI-277 is a farnesyltransferase (FTase) inhibitor. FTI-277 inhibits Ras farnesylation, blocks the phosphorylation of downstream ERK1/2 and mTOR, and reduces membrane-bound active N-ras protein. FTI-277 activates caspase 3, upregulates Bim expression, induces cell apoptosis, suppresses regulatory T cell expansion, enhances macrophage phagocytosis, and improves bacterial clearance. FTI-277 activates the PI3K/Akt signaling pathway, inhibits osteoblast differentiation, and reduces the proliferation ability of neuroblastoma cells. FTI-277 can be used in research related to head and neck squamous cell carcinoma, neuroblastoma, sepsis, and vascular calcification.

    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
