Organic amide compounds of the formula ##STR1## wherein R 1 --CO is a residue of a carboxylic acid with the proviso that the carboxylic acid is not a natural fatty acid normally bound to nitrogen of nitrogenous lipids, R 2 is a hydrogen atom, a C 1-7 alkyl group, or a C 4-7 cycloalkyl group, and R 3-N is a residue of a nitrogenous lipid. The compounds are useful in increasing or stimulating the in vivo biological activity of in vitro biologically active carboxylic acids. |
