Synthesis of new triazole fused imidazo[2,1-b]thiazole hybrids with emphasis on Staphylococcus aureus virulence factors
2019
Abstract A series of new triazole fused imidazo[2,1-b]thiazole hybrids (9a–u) were designed, synthesized and evaluated as antimicrobial agents. Compounds 9c, 9d, 9e, 9j and 9l showed promising broad spectrum antimicrobial activity. Further, compound 9c exhibited significant anti-biofilm activity with single and mixed biofilm disruption demonstrated by Field Emission Scanning Electron Microscope (FE-SEM). Furthermore, molecular docking studies revealed that they interact with the virulence factor, Staphylococcus aureus dehydrosqualene synthase (CrtM) (PDB ID: 2ZCS). Overall, the findings suggest compound 9c as potential lead for further development of novel antibacterial and anti-biofilm agents.
