A lipid-peptide microbicide inactivates herpes simplex virus.

A microbicide combining the lipid-ether 1-0-octyl-sn-glycerol (OG; 3 mM) and peptide D2A21 (9 microM) reduced herpes simplex virus type 1 (HSV-1) and HSV-2 titers by at least 1,000-fold, more than the sum of the inactivations produced by OG and D2A21 alone. OG plus D2A21 reduced HSV-1 and HSV-2 titers by > or =1,000-fold in < or =10 and < or =20 min, respectively, whereas OG and D2A21 used alone produced almost no virus inactivation during these times.
