Evaluation of Antimicrobial Effect against Some Microorganisms and Apoptotic Activity against Candida Species of New Vanillin Derivatives

Abstract

Eleven vanillin derivatives was synthesized, characterized successfully and their antibacterial andanticandidal properties were investigated on seven bacterial species and four candida species. Thesebacterial species are Staphylococcus aureus, Enterococcus faecalis, Listeria monocytogenes, Klebsiellapneumoniae, Pseudomonas aeruginosa, Escherichia coli, and Bacillus subtilis and candidal species areCandida albicans, Candida glabrata, Candida krusei and Candida parapsilosis. Most of the synthesizedcompounds were showed good activity against studied microorganisms compared with Chloramphenicol.Compounds 2c, 2d and 2k were exhibited remarkable antibacterial activities especially on Escherichia coli.In addition, Klebsiella pneumoniae, Pseudomonas aeruginosa and Bacillus subtilis were found to be themost susceptible species amongst the investigated microorganisms.
