Abstract | 231 Ethanol/aqueous extracts from New Zealand plants were screened for inhibitory activity against HIV-1 protease using fluorogenic and HPLC assays. Among the examined extracts, Pseudotsuga menziesii, Elaeocarpus hookerianus, Pernettya macrostigma and Cassinia leptophylla showed significant inhibition at a concentration of 50 μg/mL in the HPLC confirmation assay. The IC 50 values of these extracts to HIV-1 protease on its synthetic peptide substrate were 9.63, 9.74, 27.62 and 60.73 μg/mL, respectively. The derivatives of dihydroquercetin and [5'5']-bisdihydroquercetin from Pseudotsuga menziesii could be the causative compounds for the inhibition. |
