our topical, clinical candidate (iii) were synthesized. Their antimicrobial activities and aqueous stabilities at pH 4 and pH 7 were determined, and has led us to identify quaternary ammonium N,N-dichloroamines as a new class of topical antimicrobial agents.

The polyamines which were obtained by the hydrogenation of N-substituted 2-methyl-2-nitropropylamines, were derived to the corresponding guanidine derivatives with S-methylisothiourea sulfate. Some polyamines were not derived to the guanidine compound, but to the sulfates of starting materials. The material 2-methyl-2-nitropropylamines were prepared by the condensation of 2-nitropropane, formaldehyde and amines.
1-piperidyl-2-methyl-2-nitropropane at different pH and temperatures. The proposed reaction mechanism involves unimolecular dissociation of an unprotonated base as the rate-determining step with formation of immonium ions and carbanions. The dissociation rates are greatly influenced by the size both of the alkyl substituents at the amine nitrogen and of the leaving group. An excellent correlation is observed
