Fluorofenidone

Fluorofenidone (AKF-PD) is an orally active compound with anti-fibrotic, antioxidant, and anti-inflammatory pharmacological effects. Fluorofenidone downregulates the expression of ACSL4, upregulates GPX4 expression and inhibits the NF-κB signaling pathway to alleviate inflammation and fibrosis. Fluorofenidone ameliorates cholestasis and fibrosis by inhibiting hepatic Erk/-Egr-1 signaling and Tgfβ1/Smad pathway in mice. Fluorofenidone demonstrates protective effects against chronic lung injury in mice. Fluorofenidone can be used for the study of chronic obstructive pulmonary disease (COPD), pulmonary interstitial fibrosis (PIF) and non-small cell lung cancer (NSCLC)^[1][2][3]. In Vitro:Fluorofenidone (24 h) partially reverses the inhibition of cell viability and reduces the levels of inflammatory factors IL-1β, IL-6, and TNF-α in the culture supernatant induced by cigarette smoke extract (CSE) in BEAS-2B cells^[1].
Fluorofenidone (24 h) partially reverses the increase in MDA level and decrease in GSH level in BEAS-2B cell supernatant caused by CSE^[1].
Fluorofenidone (24 h) improves CSE-induced mitochondrial damage, downregulates the expression of ACSL4 and upregulates the expression of GPX4 in BEAS-2B cells^[1].
Fluorofenidone (200-800 μg/mL, 24 h) inhibits proliferation of A549 and H1299 cells in a dose-dependent manner, with EC₅₀ of 1030 μg/mL (A549) and 1118 μg/mL (H1299)^[3].
Fluorofenidone (400-800 μg/mL, 3 h) significantly reduces the percentage of EdU-positive proliferating cells^[3].
Fluorofenidone (200-800 μg/mL, 12-24 h) dose- and time-dependently inhibits cell migration and reduces the number of invasive cells in A549 and H1299 cells^[3].
Fluorofenidone (200-800 μg/mL) upregulates the expression of epithelial marker E-cadherin and downregulates mesenchymal markers MMP9, vimentin, and SNAIL in A549 and H1299 cells^[3].
Fluorofenidone (200-800 μg/mL) suppresses phosphorylation of JNK, ERK, P38 (MAPK pathway) and p-PI3K, p-AKT, p-mTOR (PI3K/AKT/mTOR pathway) in A549 and H1299 cells^[3].
In Vivo:Fluorofenidone (5 mg/kg, i.p., once daily, 7 weeks) alleviates cigarette smoke (CS)/LPS (HY-D1056)-induced lung tissue morphological damage in mice^[1].
Fluorofenidone (0.45% in diet, p.o., 14 days) markedly alleviates hepatic inflammation in 3,5-diethoxycarbonyl-1,4-dihydroxychollidine (DDC)-induced cholestasis model of mice^[2].
Fluorofenidone (400 mg/kg, p.o., daily, 3 weeks) combined with Cisplatin (HY-17394) significantly reduces the size, weight and volume of subcutaneous tumors in C57 mice bearing Lewis lung cancer cells^[3].
