Rinki Kapoor along with her PhD advisor and professor Annelise Barron of Stanford University studied novel mimics of antimicrobial peptides or peptoids for their antibacterial activity against multi-drug resistant bacteria, also known as superbugs. In one of their studies, they showed that peptoids kill resistant Pseudomonas aeruginosa -- one of the leading bug causing hospital associated infections. The group synthesised seven different peptoids and compared their activity with three different antibiotics.
In a separate study, Kapoor and Barron also revealed that peptoids kill resistant Mycobacteria -- bacteria responsible for causing Tuberculosis, a leading cause of death worldwide. In this study, published in the journal of antimicrobial agents and chemotherapy (AAC), they evaluated the efficacy of six different peptoids against Mycobacteria. "These molecules are currently under research and development and merit further studies to investigate their potential as new class of drugs for treating resistant bacterial infections," Kapoor told IANS in a statement.
