RP-832c
Based on 1 Customer Validation
RP-832c is a synthetic analogue of host defense peptides (HDP), targeting the mannose receptor CD206 on the surface of M2 polarized macrophages (Kd = 3.5 μM). RP-832c binding to CD206 induces a significant conformational change in the receptor, activating signaling pathways that lead to rapid apoptosis and repolarization of CD206-positive M2 macrophages to an M1 phenotype. RP-832c treatment significantly reduces CD206 gene expression in M2 macrophages while transiently increasing expression of TNF-α, a marker for M1 macrophages. RP-832c is used for the studies of T-cell lymphoma (CTCL) and idiopathic pulmonary fibrosis (IPF).

Biological Activity
RP-832c (0-100 μM) shows dose-dependent inhibition on M2 polarized bone marrow-derived macrophages (BMDM), with an IC50 value of 6.184 μM, producing minimal cytotoxicity on M1 polarized macrophages and has no cytotoxicity towards two different human fetal lung fibroblast cell lines, MRC5 and IMR9[2].
RP-832c (10 μM, 24 h) significantly reduces the expression of CD206 in M2 macrophages, and briefly increases the expression of TNF-α[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
-
Cell Line:M2 macrophages
-
Concentration:10 μM
-
Incubation Time:0, 2, 8 and 24 h
-
Result:Decreased CD206 gene expression.
Resulted in an initial increase in TNF-α gene expression.
RP-832c (5-10 mg/kg, s.c., once daily for 21 days) demonstrates significant preventive and therapeutic effects in the mouse model of pulmonary fibrosis[2].

-
Animal Model:Bleomycin (HY-108345) induced lung fibrosis model models established in 6-8-week-old C57BL/6 mice[2]
-
Dosage:5 and 10 mg/kg for prevention group and 10 mg/kg for treatment group
-
Administration:Subcutaneous injection (s.c.), once daily for 21 days
-
Result:significantly reduced collagen deposition in a dose-dependent manner with the alveolar structure well-preserved and the degree of fibrosis mild in prevention group.
Significantly reduces the degree of already formed fibrosis , reduced TNF-α, IL-6, IL-10, IFN-γ, CXCL1/2, etc and the expression of TGF-β1 and MMP-13 in treatment group.
Observed no significant toxicity at a dose of up to 50 mg/kg.

Solvent & Solubility
DMSO : 25 mg/mL (18.28 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month (sealed storage, away from moisture). When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (1.83 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
