Antiepileptic Drugs: Glutamate Antagonists

1.2K
Glutamate is a fundamental neurotransmitter in the central nervous system, playing a vital role in neuronal communication and various cognitive processes. Glutamate stands as the principal excitatory neurotransmitter in the brain. Its presence is crucial for the communication between neurons, underpinning essential processes such as synaptic transmission, neuronal excitability, and plasticity. These functions are vital for higher-order cognitive processes, including learning and memory. The...

Ligand-Gated Ion Channel Receptor: Gating Mechanism

4.6K
Ligand-gated ion channels are transmembrane proteins that play a vital role in intercellular communication and functions of the nervous system. They allow the influx of ions across the membrane once the neurotransmitter binds, allowing the subsequent transmission of electrical excitation across the neurons. Other ligand-gated ion channels, like the γ-aminobutyric acid (GABA) receptor, permit anions like chloride into the cells on the binding of the GABA molecule. Their entry into the cell...

Alzheimer's Disease: Treatment

1.2K
Alzheimer's Disease (AD), a neurodegenerative disorder, is pathologically identified by amyloid plaques and neurofibrillary tangles composed of tau protein. AD pharmacotherapy aims to manage cognitive symptoms, delay disease progression, and treat behavioral symptoms. The treatment is primarily symptomatic and palliative, with no definitive disease-modifying therapy available. Cholinesterase inhibitors, including donepezil (Aricept), rivastigmine (Exelon), and galantamine (Razadyne), are...

Neurochemical Transmission: Sites of Drug Action

3.9K
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...

Drugs Affecting Neurotransmitter Synthesis01:29

Drugs Affecting Neurotransmitter Synthesis

2.4K
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,...

Chemotherapy-Induced Nausea and Vomiting: Neurokinin-1 Receptor Antagonists

723
Neurokinin 1 (NK1) receptors are distributed across the GI tract, vagal afferents, and key CNS regions including the central vomiting center and chemoreceptor trigger zone (CTZ) Chemotherapy agents stimulate enterochromaffin cells in the gastrointestinal (GI) tract to release large amounts of substance P (SP). SP is a neuropeptide released by specific sensory nerves in response to many different stressors, including those in the GI mucosa affected by chemotherapy.  SP binds and activates...

Background:

  • N-Methyl-d-aspartate receptors (NMDARs) are key mediators of excitatory signaling in the central nervous system (CNS).

Purpose of the Study:

  • To review the critical role of NMDARMN in CNS function and disorders.
  • To identify and discuss potential therapeutic targets for modulating NMDARMN in CNS diseases.
  • To highlight the emerging promise of NMDAR-targeting agents as next-generation CNS therapeutics.

Main Methods:

  • Literature review of NMDAR function, involvement in CNS disorders, and therapeutic targets.
  • Analysis of established and potential molecular targets for NMDAR modulation.
  • Synthesis of current understanding regarding NMDAR-based therapeutic strategies.

  • NMDARMN is implicated in schizophrenia, depression, PTSD, aging, cognitive impairment, Alzheimer's disease, ALS, and anti-NMDAR encephalitis.
  • Identified targets for correcting NMDARMN include the glycine/d-serine co-agonist site, channel ionophore, glycine transporter-1, and d-amino acid oxidase.
  • Modulating NMDARMN presents a promising avenue for novel CNS therapeutics.

Conclusions:

  • NMDARMN plays a vital role in normal brain function and its dysfunction contributes to significant CNS disorders.
