Abstract

Herpes simplex virus type 2 (HSV-2) is a highly contagious sexually transmitted virus. The increasing emergence of drug-resistant viral strains has highlighted the crucial need for the development of new anti-HSV-2 drugs with different mechanisms. Ion channels that govern a wide range of cellular functions represent attractive targets for viral manipulation. Here, we tried to identify novel compounds to suppress HSV-2 Infection in vitro by screening a small library with ion channels modulators. We found that several T-type calcium channel blockers including benidipine, lercanidipine, lomerizine and mibefradil inhibited HSV-2 Infection, while L-type calcium channel blockers nifedipine and nitrendipine showed no significant effect on HSV-2 Infection. Furthermore, we found that benidipine exerted the Antiviral effect by suppressing the expression of viral genes in the late stage of viral Infection. In conclusion, our study suggested that T-type calcium channel blockers, which are clinically wide used, could effectively inhibit HSV-2 Infection. These findings could shed light on the mechanism and pharmacological study for HSV-2 Infection in the future.
