Benzoquinones inhibit the expression of inducible nitric oxide synthase gene

Biochem Biophys Res Commun. 1997 Oct 20;239(2):367-71. doi: 10.1006/bbrc.1997.7437.


Benzoquinones inhibited the production of NO induced by LPS and gamma-IFN in C6 glia cells. The mechanistic studies showed that benzoquinones inhibited the expression of iNOS mRNA through inactivation of NF kappa B. Benzoquinones may be a useful candidate for the development of a drug to treat disease due to iNOS gene over-expression.
