Dopamine receptors (DRs) have been implicated in numerous disorders and diseases (e.g., Alzheimer's disease, Parkinson's disease, schizophrenia, and substance use disorders) and have served as attractive drug targets for these ailments. Despite their potential clinical utility, the development of selective DR ligands has been challenging due to difficulties in selectivity among the DR subtypes as well as other biogenic amine receptors and poor pharmacokinetic properties. The realization of their full potential necessitates continued advancements in DR ligands as investigative tools. This review aims to highlight the recent developments made in the chemical biology of DR ligands (e.g., bivalent ligands, photoactivatable ligands, photoswitchable probes, and fluorescent probes).

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.
Drug Discovery: Overview
Structure-Activity Relationships and Drug Design
SAR studies the intricate relationship between a drug's chemical structure and biological activity. It focuses on understanding how modifications to a drug's structure can influence its...
Principles of Drug Action
Drugs can be agonists or antagonists. Like the endogenous ligands, agonists always bind and activate the target to produce a cellular response. Agonist binding induces a conformational change which in turn...
Ligand Binding Sites
Protein-ligand interactions are quite specific; even though numerous potential ligands surround a cellular protein at any given time, only a particular ligand can bind to that protein. Moreover, a ligand binds only to a dedicated area on the surface of the protein, known as the...
