Abstract:
Evaluation of selected compounds from our Corporate Compound Library in a human 5-HT(2C) receptor binding assay led to the discovery of WAY-629, a cyclohexyl[b][1,4]benzodiazepinoindole (K(i) 56 nM, E(max) 90%), which is selective for the 5-HT(2C) receptor versus other serotonin receptor subtypes, and dopamine, histamine, adrenergic, and muscarinic receptors. In addition, WAY-629 was active in vivo in a rat model of feeding behavior. An SAR study based on WAY-629 led to compound 11 (K(i) 13 nM, E(max) 102%).

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.
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.
