AB A large body of evidence indicates that AIDS may be the consequence of a
virus-induced antioxidant deficiency and implicates reactive oxygen
species (ROS) in the pathogenesis of HIV infection. The high level of
antigenic acid and cytokines activities in AIDS results in the
production of superoxides (O2-), hydrogen peroxide (H202) and hydroxyl
radicals (OH). HIV-infected T cells display low levels of SOD, catalase,
thioredoxin and glutatione peroxidase rendering them susceptible to
undergo apoptosis. Induction of NF kappa B and HIV replication are at
least in part dependent on reactive oxygen intermediates. We examined
the protective effects of two antioxidants. Ferulic Acid (FA) and Ethyl
Ferulate (EF) at 1, 5, 10, 10 microM on the TNF induced HIV activation
in the chronically infected promonocytic U1 cell line. FA and EF at 5
microM elicit a marked decrease of HIV p24 release. HIV inhibition was
greater after pretreatment with EF than with FA. At these
concentrations, no cytotoxicity was observed. When SOD (100 UI) was
combined with EF and FA no more inhibition was observed. But when SOD
was added alone, it induced a marked inhibition (30%). This class of
drugs may present potential interest as antiviral agents or as adjuvant
therapy in AIDS.
