Novel insulin to treat diabetes

Grant number: 1023321 | Funding period: 2012 - 2015

Completed

Abstract

The glucose regulatory hormone, insulin, remains the only treatment for type I diabetes and up to 30% of type II diabetes, both of which are among the world’s fastest growing chronic diseases today. Because insulin, if taken orally, would be broken down quickly, it has usually been given by injection. This project will develop novel chemical methods for the efficient preparation of novel insulin therapeutics with improved stability and oral bioavailability for prolonged treatment of patients.
