Dopamine is well recognized as a neurotransmitter in the brain, and regulates critical functions in a variety of peripheral systems. Growing research has also shown that dopamine acts as an important regulator of immune function. Many immune cells express dopamine receptors and other dopamine related ...

Fundamental processes in living cells are largely controlled by protein-protein interactions. The deregulation of these interactions plays a critical role in the pathogenesis of numerous diseases. Thus, PPIs represent attractive targets even though targeting them with LMW compounds still represents a major...
