Pirfenidone TGF-β inhibitor

Cat.No.S2907

Pirfenidone is an inhibitor for TGF-β production and TGF-β stimulated collagen production, reduces production of TNF-α and IL-1β, and also has anti-fibrotic and anti-inflammatory properties. Pirfenidone attenuates chemokine (CC motif) ligand-2 (CCL2) and CCL12 production with anti-fibrotic activity. Phase 3.

Mechanism of Action

Information	Pirfenidone is a potent anti-fibrotic TGF-β inhibitor. It affects TGF-β/Smad, NF-κB, and Wnt/β-catenin signaling pathways by blocking Smad2/3 phosphorylation and modulating MAPK activation, effectively inhibiting fibroblast-to-myofibroblast differentiation and extracellular matrix production to attenuate fibrosis.

Frequently Asked Questions

Question 1:
I'd like to know how to use your 50mg dose of it to make a solution for intraperitoneal injection in a mouse. Could you give me some advice?

Answer:
For I.P. injection, it can be dissolved in 2% DMSO+30% PEG 300+ddH2O at 10 mg/ml clearly. When preparing the solution, please dissolve this compound in DMSO clearly first. Then add PEG, after they mixed well, then dilute with water.

Dilution Calculator

Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:

Concentration _(start) x Volume _(start) = Concentration _(final) x Volume _(final)

This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )

*When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).
