Figure 1 Ginkgolic Acids (C13:0, C15:1, C17:1) inhibit HCMV in a dose-dependent manner and prevents plaque formation. (A) Monolayers of human foreskin fibroblasts (HFF) were inoculated with 50–100 cells infected with one of two cell-associated clinical isolates of HCMV (CH19 and BI-6) in a total of 4 wells per drug concentration followed by treatment with medium containing 0–10 µM GA.
