title: Cytotoxicities and anti-herpes simplex virus activities of diterpenes isolated from Euphorbia species.
abstract: The cytotoxicities of nine diterpene polyesters obtained from Euphorbia species were assayed by measuring their effects on the growth of Vero cells. Their antiviral effects on the multiplication of Herpes simplex virus type 2 (HSV-2) were studied by using the virus yield reduction method in cell cultures. With the exception of the strongly cytotoxic 2alpha,5alpha,14beta-triacetoxy-3beta-benzoyloxy-8alpha,15beta-dihydroxy-7beta-isobutanoyloxy-9alpha-nicotinoyloxyjatropha-6(17),11E-diene (CC(50) 3.5 microg/ml), all the tested diterpenes exhibited a pronounced or moderate anti-herpes virus effect (IC(50) values between 2.5 and 8.3 microg/ml). The observed HSV-2 inhibitory activities were not associated with virucidal effects.
