IIT Roorkee researchers have made a major stride in the global fight against antibiotic resistance. The team has developed Compound 3b, a novel drug candidate that restores the potency of a key antibiotic against deadly, drug-resistant bacteria.
Collaboration with Norwegian Scientists
As reported by pib.gov.in, the research was led by Prof. Ranjana Pathania from the Department of Biosciences and Bioengineering, with team members Dr. Mangal Singh and Perwez Bakht. They worked in collaboration with Prof. Annette Bayer and her team from UiT Tromsø, Norway. Together, they designed a molecule that works alongside the antibiotic Meropenem to treat infections caused by KPC-2-producing Klebsiella pneumoniae, a superbug listed by the World Health Organization as a top-priority threat.
Restoring Antibiotic Effectiveness
According to Prof. Pathania, this discovery offers a promising solution to one of the most urgent health challenges—antimicrobial resistance. Compound 3b neutralizes the resistance mechanism, enabling Meropenem to effectively kill the bacteria. Preclinical studies in both lab and animal models demonstrated significant reduction of bacterial lung infections.
How the Drug Works
The new molecule belongs to the β-lactamase inhibitor class of drugs, which block bacterial enzymes from breaking down life-saving antibiotics. Compound 3b is highly specific, safe for human cells, and works synergistically with Meropenem, making it an effective combination therapy against resistant strains.
Global Impact and Future Potential
Prof. K. K. Pant, Director of IIT Roorkee, emphasized that this innovation reflects the Institute’s commitment to developing impactful scientific solutions for global challenges. With antibiotic resistance on the rise, this research provides renewed hope for effective and accessible treatments.
Published in Prestigious Journal
The findings have been published in the Journal of Medicinal Chemistry. They are expected to guide future drug development efforts targeting superbugs. This marks a significant advancement in the battle against antimicrobial resistance.
