HIV-1 PR inhibition percentages of different marine extracts. Samples were dissolved in DMSO and diluted with the assay buffer to a final concentration of 100 μg/ml. Significant differences between the extracts and the DMSO control was calculated using IBM SPPS version 19. **P < 0.00, *P < 0.05 and N indicates not significant. AP indicates the experimental positive control acetyl pepstatin.
