Penciclovir
Penciclovir, a synthetic acyclic guanine derivative, containing
antiviral activity, functions as a Herpes Simplex Virus (HSV) DNA
inhibitor, is one of the drugs tested against 2019-nCoV. High nucleoside
analog concentrations of Penciclovir (EC50 = 95.96 μM, CC50
> 400 μM, SI > 4.17) [10] were needed to
reduce the viral infection and could further be examined as a COVID-19
drug [14] [15].
