title: Anti-HIV effect of gramicidin in vitro: potential for spermicide use.
abstract: Gramicidin, cation channel forming ionophore with antibacterial properties, was studied in vitro for inhibition of human immunodeficiency virus (HIV) infection of MT-4 lymphocytes. Effective antiviral concentrations required for complete HIV inactivation were three orders of magnitude lower than 10 micrograms/ml cytotoxic dose. Gramicidin, routinely used as a contraceptive agent, should be considered for clinical application as a spermicide with antiviral activity.
