Dopamine receptor blockade and the neuroleptics, a crystallographic study
The Journal of Pharmacy and Pharmacology
|August 1, 1975
Summary
Tricyclic neuroleptic drugs block dopamine receptors due to their shape matching dopamine. This study examines 12 drug structures to explain their varying effects on dopamine receptor blockage.
Area of Science:
- Medicinal Chemistry
- Neuropharmacology
- Structural Biology
Background:
- Neuroleptic drugs are crucial for treating neurological disorders.
- Understanding the mechanism of dopamine receptor blockade is key to developing effective treatments.
- Tricyclic compounds represent a significant class of neuroleptic agents.
Purpose of the Study:
- To rationalize structure-activity relationships of tricyclic neuroleptic drugs.
- To investigate the molecular basis for dopamine receptor blockade by these drugs.
- To provide evidence supporting the conformational complementarity theory.
Main Methods:
- X-ray crystallography of 12 tricyclic drugs.
- Detailed structural analysis of drug molecules.
- Comparison of drug structures with dopamine.
Main Results:
- Examined the X-ray structures of 12 tricyclic neuroleptic drugs.
- Identified specific structural features relevant to dopamine receptor interaction.
- Observed conformational similarities between drug molecules and dopamine.
Conclusions:
- The ability of neuroleptics to block dopamine receptors is linked to their structural conformation.
- Conformational complementarity between tricyclic drugs and dopamine supports their receptor binding mechanism.
- Structural insights can guide the design of novel neuroleptic agents.

01:26Neurochemical Transmission: Sites of Drug Action
Neurochemical transmission, the conduction of electrical impulses between neurons mediated by neurotransmitters, plays a vital role in various physiological processes. Autonomic drugs exert their effects by modulating neurotransmission within the autonomic nervous system. For instance, drugs such as hemicholinium block the precursor uptake necessary for synthesizing acetylcholine, an essential autonomic neurotransmitter. Following synthesis, neurotransmitters are stored in vesicles. Metyrosine...
01:21Drugs Affecting Neurotransmitter Release or Uptake
Certain drugs can affect how neurotransmitters called catecholamines, are released or taken back up in the adrenergic neuron. They can have different effects on the body's sympathetic transmission. Reserpine, a natural compound found in the Rauwolfia shrub, blocks a transporter called vesicular monoamine transporter (VMAT), which leads to a buildup of catecholamines in the cell and reduces sympathetic transmission. Another drug called guanethidine works in multiple ways, including blocking...
01:29Drugs Affecting Neurotransmitter Synthesis
Drugs affecting neurotransmitter synthesis can impact the adrenergic neuron and the synthesis of neurotransmitters. For example, α-methyltyrosine and carbidopa target specific enzymes involved in catecholamine synthesis. α-methyltyrosine inhibits the enzyme tyrosine hydroxylase, which converts tyrosine into dopamine. By blocking this enzyme, α-methyltyrosine reduces dopamine production and other catecholamines. Carbidopa, on the other hand, inhibits the enzyme dopa decarboxylase, which converts...
01:21Antipsychotic Drugs: Typical and Atypical Agents
Antipsychotic drugs are classified into first-generation (typical) drugs including phenothiazines; and second-generation (atypical) drugs. Chlorpromazine hydrochloride (Thorazine), a phenothiazine derivative, broadly impacts the central, autonomic, and endocrine systems. This drug, along with typical agents like haloperidol (Haldol), primarily works by antagonizing D2 receptors, thus reducing dopaminergic neurotransmission. However, typical antipsychotics can cause side effects such as sedation...
01:24Parkinson's Disease: Treatment
Neurodegenerative disorders, such as Parkinson's Disease (PD), involve the gradual and irreversible destruction of neurons in particular brain areas. These disorders exhibit standard features like proteinopathies, selective vulnerability of some neurons, and an interaction of intrinsic properties, genetics, and environmental influences in neural injury.
Parkinson's Disease is primarily a result of the loss of dopaminergic neurons in the substantia nigra pars compacta. The cornerstone of its...

01:29Chemotherapy-Induced Nausea and Vomiting: Dopamine Receptor Antagonists
Dopamine receptor antagonists, also known as antipsychotic agents, are critical in managing chemotherapy-induced vomiting. These antiemetic agents block dopamine receptors in the chemoreceptor trigger zone (CTZ), inhibiting signal transmission to the vomiting center. Antipsychotic agents encompass phenothiazines (PTZ), butyrophenones, benzamides, and thienobenzodiazepines (Zyprexa), which are utilized for their antiemetic and sedative properties.
