Resveratrol inhibits rhinovirus replication and expression of inflammatory mediators in nasal epithelia.

Human rhinoviruses (HRV), the cause of common colds, are the most frequent precipitants of acute exacerbation of asthma and chronic obstructive pulmonary disease, as well as causes of other serious respiratory diseases. No vaccine or antiviral agents are available for the prevention or treatment of HRV infection. Resveratrol exerts antiviral effect against different DNA and RNA viruses.

Resveratrol is a polyphenolic compound endowed with multiple health benefits. However, its limited bioavailability and poor stability in solution hamper its use in pharmaceutical applications. Due to its low solubility in water, solvents such as ethanol and dimethyl sulfoxide are often used to dissolve resveratrol.
