Synthesis and evaluation of antibacterial and antibiofilm activities of pyridin-2-yl hexanoate

Abstract Synthesized Pyridin-2-yl hexanoate was screened for its antibacterial and antibiofilm activities using the broth microdilution method and XTT assay respectively. The obtained results revealed that synthesized molecule inhibited the growth of pathogenic bacteria (MICs value ranged from 80 to 640 μg ml −1 ). Moreover, it induced a strong antibiofilm effect against Gram positive cocci (BIC 50 was 366, 378 and 412 μg ml −1 for Streptococcus mutans ATCC 25175 , Streptococcus salivarius ATCC 13419 and Streptococcus oralis ATCC 6249 respectively). Basis on these results, pyridin-2-yl hexanoate may be considered as effective compound with antibacterial and antibiofilm activities.
