Apocynin is a naturally occurring compound derived from the root of Picrorhiza kurroa and is primarily known as an inhibitor of NADPH oxidase, an enzyme complex involved in the production of reactive oxygen species (ROS). Its role in fibrosis has been explored in preclinical (animal and cell culture) models, where oxidative stress is a recognized contributor to fibrotic processes in organs such as the lung, liver, and kidney. Several studies have demonstrated that apocynin can attenuate markers of fibrosis, decrease inflammation, and reduce collagen deposition in models of pulmonary fibrosis, hepatic fibrosis, and renal fibrosis. The proposed mechanism is through the suppression of ROS production, leading to the modulation of pro-fibrotic signaling pathways, such as TGF-β/Smad signaling.
However, the evidence base remains limited to preclinical studies, with no high-quality human clinical trials available to date. While the mechanistic rationale is supported by experimental findings, the translation of these results into clinical practice has not yet occurred. Therefore, while there is some scientific support for apocynin’s anti-fibrotic effects in laboratory settings, evidence in humans is currently lacking. Apocynin is not a standard or widely accepted therapy for fibrosis in clinical medicine, and its safety and efficacy in this context remain to be established through rigorous clinical research.
