11

Aim and Scope:

The present research project include three major parts, as follows: 1. The syntheses and chemical characterization of various new compounds, expected to act as dopaminergic-serotonergic receptor ligands, or alternatively as the opioid receptor ligands, particularly NOP receptor antagonists. 2. Pharmacological characterization of the synthesized compounds as the potential ligands, such as the binding activity estimation, determination of the ligand properties including the agonist or the antagonist activity, possible neuroprotective action, as well as the behavioral studies of the laboratory animals. 3. Theoretical modeling, encompassing QSAR analysis, molecular dinamics, ab initio calculations, and docking simulations of ligand-receptor interactions.

Major Results:

• modeling second extracellular loop of dopamine D2 receptor
• optimizing the optimal selectivity and affinity towards specific class of receptors
• confirmed neuroprotective capacity of newly sinthesized ligands
• α1 receptor modelling and testing with previously sinthesized ligands and with literature ligands
