CAS No. 53179-13-8
Pirfenidone (S-7701, AMR-69) 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.

|Description||Pirfenidone (S-7701, AMR-69) 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.|
Pirfenidone (< 300 μg/mL) suppresses the proinflammatory cytokine tumor necrosis factor-α (TNF-α) by a translational mechanism in RAW264.7 cells, which is independent of activation of the mitogen-activated protain kinase (MAPK) 2, p38 MAP kinase, and c-Jun N-terminal kinase (JNK).  Pirfenidone (< 10 mM) leads to reduced glioma cell density in concentration-dependent manner in LN-18, T98G, LNT-229 and LN-308 cell lines. Pirfenidone (< 5 mM) reduces TGF-β bioactivity by affecting TGF-β2 mRNA expression and processing of pro-TGF-β in CCL-64 cells. Pirfenidone (< 8.3 mM) inhibits the activity of recombinant furin and downregulates the expression of MMP-11 in a dose-dependent manner in LN-308 cells. 
|In vivo||Pirfenidone (250 mg/kg) potently inhibits the production of the proinflammatory cytokines, TNF-alpha, interferon-gamma, and interleukin-6, but enhances the production of the anti-inflammatory cytokine, interleukin-10, in mice.  Pirfenidone (250 mg/kg/day) ameliorates cyclosporine-induced fibrosis by about 50% and decreases TGF-beta1 protein expression by 80% in Sprague-Dawley rats receiving a low-salt diet.  Pirfenidone (400 mg/kg/day) inhibits heat shock protein 47-positive cells and myofibroblasts, the principal cells responsible for the accumulation and deposition of extracellular matrix seen in pulmonary fibrosis in ICR mice intravenously injected with bleomycin.  Pirfenidone (0.5%, liquid diet) treatment reduces the degree of liver injury in rats, as determined by alanine aminotransferase values and necro-inflammatory score, which is associated with reduced hepatic stellate cells proliferation and collagen deposition. Pirfenidone (0.5%, liquid diet) administration downregulates dimethylnitrosamine induced transcripts levels of procollagen alpha1(I), TIMP-1 and MMP-2 by 50-60% in rats, and this is associated with a 70% reduction in collagen deposition. |

1.Please make sure the liquid is clear before adding the next solvent.
2.Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
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).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.

Frequently Asked Questions
I'd like to know how to use your 50mg dose pirfenidone to make a solution for intraperitoneal injection in a mouse. Could you give me some advice?
For I.P. injection, S2907 Pirfenidone can be dissolved in 2% DMSO+30% PEG 300+ddH2O at 10 mg/ml clearly. When preparing the solution, please dissolve the compound in DMSO clearly first. Then add PEG, after they mixed well, then dilute with water.
