New Therapeutic Concepts

In the research area “New Therapeutic Concepts”, the DZD is developing new approaches to therapy and treatment. Discoveries from basic research, such as innovative molecular targets or candidate molecules for new diabetes drugs are being developed further and transferred to clinical practice. The DZD experts are pursuing the following objectives: 

  • Discovery of new targets for drugs
  • Development of new type 2 diabetes drugs
  • Replacement and preservation of beta cells by means of stem cell therapies (Link)
  • Development of new therapies for type 1 diabetes (Link)

New Active Substances: Bi- and Trivalent Hormone Molecules


DZD scientists are developing different synthetic hormone molecules, each combining the effect of two or three natural gut or pancreatic hormones. Thus, the researchers have succeeded in mimicking a surgical method for weight loss by means of less risky methods. A gastric bypass can be imitated by combining several hormones into a new active ingredient - a multihormone molecule.

A new active substance that combines the effects of the three gastrointestinal hormones GLP-1, GIP, and glucagon lowers blood glucose levels and reduces the body fat to a previously unknown extent. In the animal model, the triple hormone not only drastically lowers blood glucose levels, reduces appetite and body fat, but also improves fatty liver, cholesterol and calorie burning more effectively than previously available mono-acting or dual-acting molecules. The tri-agonist reduced body weight by about 30 percent.

In order to better treat the fatty liver in the future, DZD researchers have engineered chemical conjugates of the thyroid hormone T3 and glucagon, enabling targeted delivery into liver cells in order to stimulate the metabolism there. The new active substance does not infiltrate tissues without glucagon receptors. Thus, adverse effects on cardiac function and bone integrity are avoided.
