Abstract
In this study, we aimed to synthesize some new quinoxaline derivatives bearing amide
moiety and to evaluate their antimicrobial activity. A set of 16 novel compounds of
N-[2,3-bis(4-methoxy/methylphenyl)quinoxalin-6-yl]-substituted benzamide derivatives
were synthesized by reacting 2,3-bis(4-methoxyphenyl)-6-aminoquinoxaline or 2,3-bis(4-methylphenyl)-6-aminoquinoxaline
with benzoyl chloride derivatives in tetrahydrofuran and investigated for their antimicrobial
activity. The structures of the obtained final compounds were confirmed by spectral
data (IR, 1H-NMR, 13C-NMR and MS). The antimicrobial activity of the compounds were determined by using
the microbroth dilution method. Antimicrobial activity results revealed that synthesized
compounds exhibited remarkable activity against Candida krusei (ATCC 6258) and Candida parapsilosis (ATCC 22019).
