KANSAS CITY, Mo. – Researchers at the University of Missouri-Kansas City have discovered a way to make insulin administration easier and more effective. This breakthrough could affect tens of millions of Type 1 diabetics worldwide by replacing needle sticks with a beam of light.
           Although insulin can treat Type 1 diabetes, administering multiple daily injections is taxing, and inconsistently effective. Researchers with UMKC’s School of Pharmacy have developed a new method called a photoactivated depot. They wrote about the advance for an upcoming issue of Angewandte Chemie, the highest ranked weekly chemistry journal in the world.
           With a photoactivated depot (PAD), insulin is linked to an insoluble polymer by a connection that can be broken with light. The depot can be injected just under the patient’s skin. Insulin can then be released from the polymer by light irradiation through the skin, and then absorbed into the body. Since one injected depot can contain a large amount of insulin, the PAD has the potential to eliminate hundreds of injections. In addition, because light can be administered at any time interval, the release of insulin could be more finely controlled.
              Simon Friedman, associate professor of pharmacy and his student co-authors, Piyush Jain and Dipu Karunakaran, successfully made the first generation of PAD’s. The results have just been published in Angewandte Chemie.
“A project like this comes along once in a career if you’re lucky.  We’re aiming to improve the lives of diabetics all over the world,” Friedman said.
              The article, entitled “A Photoactivated Insulin Depot” was called “a paradigm shift” and “truly innovative” by the journal’s reviewer. This research has the potential to directly impact the health outcomes of tens of millions of type 1 diabetics worldwide.
