RP-182 acetate is a synthetic immunomodulatory peptide that exerts anti-tumor effects by targeting the mannose receptor CD206 (Kd = 8 μM) on the surface of tumor-associated macrophages (TAMs). RP-182 acetate induces a conformational switch of the CD206 receptor, which activates NF-κB signaling and phagocytosis in CD206high TAMs. RP-182 acetate has dual function: activation of canonical NF-κB signaling, triggering TNFα secretion and autocrine activation of the TNF receptor 1 (TNFR1), leading to activation of caspase 8, apoptosis, and cell death. RP-182 acetate is used in pancreatic cancer and melanoma research.

Description

RP-182 acetate is a synthetic immunomodulatory peptide that exerts anti-tumor effects by targeting the mannose receptor CD206 (Kd = 8 μM) on the surface of tumor-associated macrophages (TAMs). RP-182 acetate induces a conformational switch of the CD206 receptor, which activates NF-κB signaling and phagocytosis in CD206high TAMs. RP-182 acetate has dual function: activation of canonical NF-κB signaling, triggering TNFα secretion and autocrine activation of the TNF receptor 1 (TNFR1), leading to activation of caspase 8, apoptosis, and cell death. RP-182 acetate is used in pancreatic cancer and melanoma research[1][2].

In Vitro

RP-182 acetate (1 nM-1 mM, 48 h) increases cell killing of CD206high M2-like macrophages with an IC50 of 17.6 μM through the MyD88/NF-κB pathway[1][2].
RP-182 acetate (0.1 μM, 2-24 h) internalizes CD206, activated NF-κB, and increased IRF7 phosphorylation in IL-4-polarized M2 bone marrow-derived macrophages[1][2].
RP-182 acetate (3-30 μM, 24 h) increases levels of inflammatory factors secreted by macrophages, indicating immune reprogramming[1][2].

Help & FAQs
  • 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.
