Inhibition of herpes virus plaquing capacity in human diploid fibroblasts treated with gilvocarcin V plus near UV radiation

Photochem Photobiol. 1990 Apr;51(4):477-9. doi: 10.1111/j.1751-1097.1990.tb01740.x.


The capacity of human fibroblasts to support plaque formation by Herpes simplex virus following treatment of the cells with gilvocarcin V, a polyaromatic C-glycoside, plus near ultraviolet radiation (UVA, 320-400 nm) was examined. Gilvocarcin V, plus UVA radiation, effectively inhibited host cell capacity at concentrations five orders of magnitude lower than that of 8-methyoxypsoralen required for capacity inhibition at similar levels of UVA radiation. This result extends the observation of unusual biological potency of UVA-activated gilvocarcins from bacterial cells to human cells.
