Abstract
The present invention reveals the isolation, purification and characterization from the creosote bush Larrea tridentata of compounds of the structural formula: ##STR1## where R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are each selected from the group consisting of HO--, CH.sub.3 O-- and CH.sub.3 (C.dbd.O)O--, provided that R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are not each HO-- simultaneously. Each compound is a derivative of 1,4-bis-(3,4-dihydroxyphenyl)-2,3-dimethylbutane (nordihydroquaiaretic acid, NDGA). In addition, NDGA and each derivative can be used in a method to suppress Tat transactivation of a lentivirus, including the HIV virus, in a cell by administering NDGA or a derivative of NDGA to the cell.
