Table 2. Inhibitory effects of HM in combination with Acyclovir.
Compound | EC50 | FICcompound + FICACV | Inhibitory effect |
---|---|---|---|
HSV-2 | HSV-2 | ||
Isolated HM alone | 1.5 ± 0.1 | - | - |
Acyclovir alone | 2.9 ± 0.1 | - | - |
Acyclovir + HM | 0.73 ± 0.1 | 0.92 | No interaction |
The interaction between HM and ACV was interpreted according to the combined FIC index [FICcompound + FICACV] as synergy (≤0.5), no interaction (0.5 - 4) or antagonism (>4) (32).
