title: Structure activity correlation for diuretic furosemide congeners.
abstract: The structure activity correlation of several groups of anthranilic acid derivatives was studied. 59 compounds, most of them possessing the anthranilic acid moiety, were synthesized and tested for diuretic and saluretic activities. Equations correlating the biological activities of these compounds with their physicochemical constants suggest positive dependence of the diuretic activity on log P (octanol:water partition coefficient). It is concluded that, within limits, the variation in biological activity is primarily governed by the lipophilicity of the molecule, and further increase in log P value will not enhance this activity.
