Abstract
Previously unknown sulfur-containing alcohol, 1-(benzylsulfanyl)octan-2-ol, was synthesized in 65% yield and involved in the Mannich condensation with formaldehyde and aliphatic (diethyl-, dibutyl-, dipropyl-, dipentyl-, dihexylamine) or cyclic (piperidine, morpholine, hexamethyleneimine) secondary amines, which afforded new [1-(benzylsulfanyl)octan-2-yloxy]methanamines in 68–75% yields. The products were characterized by physical constants, and their structure was confirmed by elemental analyses and IR, 1H NMR, and mass spectra. They were isolated as colorless liquids with a characteristic odor, which are insoluble in water and readily soluble in organic solvents. The synthesized compounds were screened for antimicrobial activity against pathogenic and conditionally pathogenic microorganisms by the serial dilution method. The tested compounds proved to be more potent than medically used ethanol, phenol, ethacridine lactate, nitrofungin, nitrofurazone, and chloramine. The synthesized compounds were also tested as antimicrobial oil additives and were found to effectively inhibit the growth of Aspergillus niger, Candida tropicalis, Mycobacterium lacticola, and Pseudomonas aeruginosa.
