Potential of fat-soluble vitamins as a platform for antiviral drug development

Abstract

Fat-soluble vitamins, including vitamins A, D, E, and K, exhibit antioxidative, anti-inflammatory, and immunomodulatory effects, making them promising candidates for antiviral drug development. This review highlights their structural features, biological roles, and antiviral potential. Vitamin A derivatives modulate immunity and inhibit viral replication, including SARS-CoV-2. Vitamin D analogs enhance immune responses and target viral enzymes, while vitamin E derivatives reduce oxidative stress and may directly inhibit viral replication. Emerging research on vitamin K derivatives suggests potential antiviral applications. These findings underscore the potential of fat-soluble vitamins as innovative antiviral agents, warranting further investigation to optimize efficacy and clinical use.
