Abstract
A series of fatty acid amides anilides was prepared and a number of compounds in the series were found to be highly active against gram positive bacteria but ineffective against gram negative organisms. The N,N-dimethyl- and N,N-diethylamides of C12-C14 fatty acids had minimal inhibitory concentration (MIC) values of 100 ppm or less. Substituted anilides of C6-C11 fatty acids were active when the following groups were attached to the aromatic ring: 3,4-dichloro, 3-nitro, 4-nitro, 5-chloro-2-hydroxy, 4-chloro-3-nitro, and 2-hydroxy-5-nitro. Some of these compounds had a MIC value of 0.1 ppm. Significantly, the presence of soap did not reduce the activity of these bacteriostats, whereas polysorbate 80 at high concentrations deactivated the compounds.
