Research on antibacterial and antifungal agents. XI. Synthesis and antimicrobial activity of N-heteroaryl benzylamines and their Schiff bases
摘要:
The synthesis and antimicrobial activity of new N-heteroaryl benzylamines and their Schiff bases are reported. Antifungal data were compared with those obtained with miconazole ketoconazole, enilconazole and imazalil sulfate; which showed that some of the tested compounds possessed moderate activity against strains of Candida albicans, Candida sp and good activity against isolates of plant pathogenic fungi, In contrast the synthesized compounds showed poor antibacterial activity, except for 3j which exhibited a better activity than nalidixic acid used as positive control. The results obtained are discussed on the basis of structure-activity relationships.

The 70 eV electron impact mass spectra of some para-substituted N-heteroaryl benzylamines, synthesized through the corresponding Schiff bases, are reported. Typical fragmentation patterns are discussed with the aid of mass analyzed ion kinetic energy spectra and exact mass measurements. The compounds are relatively stable under electron impact, the molecular ion being the base peak or the second most intense ion in the spectra. The dominating breakdown process is the benzylic cleavage, that gives rise to the base peak in some of the investigated compounds and to the second intense peak in others.
