Pirfenidone (formerly AMR69; S7701, AMR-69; S-7701; trade name: Pirespa; Pirfenex; Deskar, Esbriet) is a potent inhibitor for TGF-β production and TGF-β stimulated collagen production with anti-fibrotic and anti-inflammatory properties. It has been used as a medication for the treatment of idiopathic pulmonary fibrosis. It reduces production of TNF-α and IL-1β, and also has anti-fibrotic and anti-inflammatory properties. Pirfenidone is an anti-fibrotic drug for the treatment of idiopathic pulmonary fibrosis (IPF). It works by reducing lung fibrosis through downregulation of the production of growth factors and procollagens I and II.
ln Vitro |
The furin substrate matrix metalloproteinase (MMP)-11, a TGF-β target gene implicated in carcinogenesis, had its protein levels decreased by pirfenidone (PFD). According to these findings, PFD or PFD-related medicines are prospective treatments for human malignancies linked to increased TGF-β activity[1]. Through a translational mechanism, pirfenidone inhibits the proinflammatory cytokine TNF-α in RAW264.7 cells, a murine macrophage-like cell line, without requiring activation of MAPK2, p38 MAPK, or JNK. Pirfenidone significantly reduces the synthesis of proinflammatory cytokines such as TNF-α, interferon-γ, and interleukin-6 in the murine endotoxin shock model, while increasing the synthesis of interleukin-10, an anti-inflammatory cytokine[2]. PFD (pirfenidone) exhibits its inhibitory effects on HLEC growth. After 24 hours, there is a reduction in cell growth in the 0.3 mg/mL group compared to the control group (P=0.044). At 24, 48, and 72 hours, the impact is more noticeable in the 0.5 mg/mL group (P<0.05). At all time points, 1 mg/mL PFD virtually entirely inhibits growth (P<0.01)[3].

ln Vivo |
Pirfenidone (300 mg/kg/day) was administered for four weeks. When pirfenidone is given to mice treated with Bleomycin (BLM), the score is dramatically reduced (P<0.0001). In addition, lung collagen content is measured in order to assess Pirfenidone's anti-fibrotic properties. When compared to mice treated with saline or pirfenidone, the lungs of BLM-treated mice have a significantly higher collagen content, and this rise is dramatically reduced when pirfenidone is administered on day 28 following BLM treatment (P=0.0012)[4].

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
