Abstract :Nitrogen heterocyclic compound play an important role in medicinal chemistry due to their
biological activities towards microorganisms. Differently substituted Naphthalene and Triazine
incorporated heterocyclic compounds were synthesized and screened for antibacterial activity
against Gram-positive and Gram-negative bacteria and anti-fungal activity. These aromatic
nitrogen heterocyclic derivatives displayed remarkable in vitro antimicrobial activities against E.
coli AT CC25922, S.aureus ATCC 25923, P. aeruginosa ATCC 27853, Streptococcus mutans (MTCC
890), K. pneumoniae and Bacillus subtili re-cultured bacterial strain and A. flavus, A. fumigatus, P.
marneffei, T. mentagrophytes, C. Albicans.
