IIT Mandi discovers molecule for Type 1 & 2 diabetes treatment

02 May 2022 | News

The molecule PK2 increases insulin release, prevents and reverses beta cell loss, making it effective for both Type 1 and Type 2 diabetes

Researchers at the Indian Institute of Technology (IIT) Mandi have identified a drug molecule that can be used to treat diabetes. The molecule PK2 can trigger the release of insulin by the pancreas and can potentially be used as an orally administered medicine for diabetes.


The findings of the research have been published in the Journal of Biological Chemistry. The paper has been authored by Dr Prosenjit Mondal, Associate Professor, School of Basic Sciences, and co-authored by Prof Subrata Ghosh, School of Basic Sciences, IIT Mandi, along with Dr Sunil Kumar, ICAR- IASRI, PUSA, New Delhi, Dr Budheswar Dehury, ICMR RMRC, Bhubaneswar, Dr Khyati Girdhar, Shilpa Thakur, Dr Abhinav Choubey, Dr Pankaj Gaur, Surbhi Dogra, Bidisha Biswas from IIT Mandi, and Dr Durgesh Kumar Dwivedi (Regional Ayurvedic Research Institute (RARI) Gwalior).


The multi-institutional team first used computer simulation methods to screen various small molecules that can bind with GLP1R. While PK2, PK3, and PK4 had good binding abilities with GLP1R, they subsequently chose PK2 because of its better solubility in solvents. The researchers then synthesised PK2 in the lab for further testing. 

In order to test the biological effects of PK2, the researchers administered it orally to experimental mice developing diabetes and measured glucose levels and insulin secretion. There was a six-fold increase in serum insulin levels in PK2-treated mice over the control group.  These findings provide hope for inexpensive oral drugs for diabetic patients.
