Abstract:
Structure-activity relationship (SAR) studies are a key feature of peptide and peptidomimetic research to improve the biological properties of native peptides and convert them into more drug-like compounds. Peptide SAR studies involve the systematic modification of a lead peptide to provide insight into the molecular determinants of the ligand-receptor interactions that result in either receptor stimulation or inhibition. This chapter will discuss structure-activity relationships of the endogenous and synthetic agonists and the antagonists of the melanocortin system.

Adrenergic Agonists: Chemistry and Structure-Activity Relationship
Aromatic ring substitutions: Substituting the aromatic ring with –OH groups at positions 3 and 4 yields catecholamines (e.g., epinephrine), which have a high affinity for adrenoceptors. Hydrogen bonding between –OH groups and receptors enhances adrenergic activity.

Drug-Receptor Interaction: Agonist
Agonists can bind to receptors in different ways. Some agonists bind directly to the receptor's active site, mimicking the endogenous ligand's action.

α-adrenoceptors are further divided into α1 and α2-adrenoceptors.
α1-Adrenoceptors: These receptors are located postsynaptically on the effector organs and cause constriction of smooth muscle mediated by activation of phospholipase C—inositol-1,4,5-trisphosphate...
