Newly synthesized indolizine derivatives – antimicrobial and antimutagenic properties

Abstract

AbstractA series of indolizine derivatives have been synthesized and subjected to antibacterial screening studies. Antibacterial activity of 21 derivatives was investigated against Staphylococcus aureus, Mycobacterium smegmatis, Salmonella typhimurium and Escherichia coli; also, the sensitivity of model yeast Candida parapsilosis and some model filamentous fungi Aspergillus fumigatus, Alternaria alternata, Botrytis cinerea and Microsporum gypseum was tested. Newly synthesized indolizine derivatives have shown selective toxicity to Gram-positive bacteria S. aureus and were also considered to be able to inhibit the acidoresistant rod M. smegmatis. Derivative XXI has shown the highest inhibition effect with the bacteriostatic effect on the cells at the concentration of 25 μg mL
