Pirfenidone (S-7701) Chemical Structure

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.

Biological Activity

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.
TGF-β [2]
(Cell-free assay)
In vitro

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). [1] 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. [2]

Methods Test Index PMID

PubMed: 22132230     

Effects of 1.0 or 1.5 mg/ml pirfenidone on α-SMA expression and morphological changes of CFs (Cardiac fibroblasts) were determined by immunofluorescence staining with anti-α-SMA antibody. Scale bar = 50.0 µm. 

SMAD4 / SMAD2 / SMAD3 ; 

PubMed: 23437252     

After stimulated by 12.5 ng/ml TGF-β2 for 24 hours, the staining of nuclei SMAD4 (green) enhanced when that of SMAD4 in the cytoplasm were weakened, and SMAD2/3 proteins (red) were assembled on the nuclear membrane and some of them entered the nuclei. Expression of nuclei SMAD2/3 and SMAD4 were depressed after treatment with 0.5 mg/ml pirfenidone. The nuclei stained by DAPI (blue). Magnification, ×1000.

F-actin / β-catenin / Vimentin ; 

PubMed: 29325547     

Immunofluorescence staining showed that treatment with SB or PFD increased E-cadherin levels, decreased vimentin and nuclear β-catenin distribution in MCF-7 and MDA-MB-231 cells. CAFs promoted F-actin polymerization and stability in cancer cells, whereas treatment with SB or PFD impaired the formation of stress fibers. Scale bar: 15 μm

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. [1] 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. [3] 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. [4] 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.

Frequently Asked Questions

  • Question 1:

    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?

  • Answer:

    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.
