Back to previous list
Bioassay-guided fractionation of the leaves of Perovskia atriplicifolia (Russian sage) resulted in the isolation of four previously known flavonoid derivatives, 5-hydroxy-6,7,3',4'-tetramethoxyflavone (1), 5,7-dihydroxy-6,3',4'-trimethoxyflavone (2), 5-hydroxy-6,7,4'-trimethoxyflavone (3), and 5,7-dihydroxy-6,4'-dimethoxyflavone (4). Compounds 1, 3, and 4 showed displacement of the radioligand for the cloned human delta opioid receptor with Ki values ranging from 3.1 to 26.0 muM. In addition, the binding mode of the compounds in the active site of the delta opioid receptor was investigated through molecular modeling algorithms. This study may have implications in better understanding non-nitrogenous delta opioid receptor ligands.
