the protein-ligand complex mechanisms may allow us for the treatment of some diseases such as type 2 diabetes. Glucagon receptor inhibitors are promising for the treatment of type 2 diabetes. Inhibitors of Glucagon receptors are either glucagon neutralizers or small molecular antagonists, and they all rely on the concept of protein-ligand complex interaction.
