Virucidal, attachment and penetration inhibitory effects of samples obtained from Petromica citrina on HSV-1 (KOS strain) replication.

Samples VC50 a AC50 b PC50 c
TSH fraction 0.38 ± 0.12 6.41 ± 0.63 2.45 ± 1.33
Compound 1 0.48 ± 0.04 7.84 ± 1.03 5.67 ± 0.47
Compound 2 1.08 ± 0.36 12.26 ± 3.58 8.90 ± 1.86
Dextran sulfate NA <15.62 <15.62

Values represent the mean ± standard deviations of three independent experiments. NA = no activity; a 50% virucidal concentration (µg/mL); b 50% attachment inhibitory concentrations (µg/mL); c 50% penetration inhibitory concentrations (µg/mL).
