The invention provides novel antibacterial compounds of formulae IA, IB and IC as defined herein. Optionally, the antibacterial compounds can be bonded to a delivery agent that is capable of bonding to one or more structures on a bacterial cell membrane. The invention also provides the use of such compounds in treating or preventing bacterial infections, and processes for their synthesis.

experimental part, p. 236 - 246 (2012/07/02)
Aminomethylation of thiourea with aqueous formaldehyde and simple amino acids (glycine, β-alanine, γ-aminobutyric acid) have resulted in the formation of (4-thioxo-1,3,5-triazinan-1-yl)-substituted acetic, propionic, and butyric acids, respectively. By alkylation of these compounds corresponding S-methyl and S-ethyl iodides were obtained, and by the action of tert-butylamine, the corresponding salts. The same salts were obtained by the reaction of amine exchange between 5-tert-butyl-1,3,5-triazinan-2-thione and these amino acids in water. As a result of neutralization of S-methyl iodides with tert-butylamine in 2-propanol or aqueous 2-propanol zwitterionic [4-(methyl-sulfanyl)-3,6-dihydro-1,3,5-triazin-1(2H)-yl] derivatives of these acids were isolated. From aqueous solutions of S-methyl iodides and tert-butylamine ion associates of the corresponding zwitter-ions and tert-butylammonium iodide have crystallized. The same associates have formed at treating S-methyl iodides with tert-butylamine or diethylamine in the absence of a solvent. Pleiades Publishing, Ltd., 2012.
