Researchers at Tohoku University in Japan have recently invented a simple method for chemical synthesis of insulin, and it is expected to develop new methods for producing insulin preparations to provide insulin for patients with diabetes.
Insulin is a substance secreted by islet beta cells in the pancreas that controls blood sugar. Many people with diabetes now need insulin. These insulins are usually produced bioengineered rather than chemically. This is because the insulin molecule consists of two polypeptide chains called the A chain and the B chain, and it is difficult to assemble them chemically.
Researchers from Northeastern University, Tokai University, and Osaka University have collaborated with German counterparts to find that A and B chains can be assembled together in low temperature, alkaline solutions that meet specific conditions. The researchers first synthesized bovine insulin using this technique and then synthesized human insulin.
The researchers say that the advantage of this synthesis is that it is simple to operate, does not require the use of genetic technology like bioengineering methods, and does not require large-scale equipment. It is hoped that this technology will be moved from the laboratory to the actual application and further research and development. A new method of producing insulin preparations.
