Insights

Targeting specific reactive oxygen species (ROS) sources, like NADPH oxidase (NOX) enzymes, offers a promising therapeutic strategy for central nervous system (CNS) diseases, unlike general antioxidant treatments.

Area of Science:

  • Neuroscience
  • Biochemistry
  • Pharmacology

Background:

  • Oxidative stress is a key pathogenic mechanism in central nervous system (CNS) diseases.
  • Previous antioxidant therapies targeting reactive oxygen species (ROS) have failed in clinical trials for CNS disorders.
  • NADPH oxidase (NOX) enzymes are significant generators of ROS in the CNS.

Purpose of the Study:

  • To review the potential of targeting NOX enzymes for treating CNS pathologies.
  • To explore NOX enzymes as a therapeutic target for various neurological and psychiatric disorders.
  • To discuss the dual role of NOX-generated ROS in CNS diseases and autoimmune conditions.

Main Methods:

  • Literature review of studies on oxidative stress, NOX enzymes, and CNS diseases.
  • Analysis of the role of NOX enzymes in the pathogenesis of neurodegenerative and psychiatric disorders.
  • Examination of the protective effects of NOX-derived ROS in autoimmune demyelinating diseases.

Main Results:

  • NOX enzymes contribute to the progression of diverse CNS disorders including neurodegenerative diseases and stroke.
  • ROS generated by NOX enzymes can be protective in autoimmune demyelinating diseases by modulating immune responses.
  • Targeting specific NOX isoforms may offer a more effective therapeutic approach than broad antioxidant administration.

Conclusions:

  • Targeting NOX enzymes represents a promising therapeutic avenue for currently incurable CNS pathologies.
  • Development of specific NOX inhibitors or modulators could lead to novel disease-modifying drugs.
  • Understanding the specific roles of NOX enzymes is crucial for developing effective CNS disease treatments.

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against specific...
Targets for Drug Action: Overview01:26

Targets for Drug Action: Overview

Drugs target macromolecules to modify ongoing cellular processes. Primary drug targets include receptors, ion channels, transporters, and enzymes.
Receptors are either membrane-spanning or intracellular proteins, which upon binding a ligand, get activated and transmit the signal downstream to elicit a response. Drugs bind receptors, either mimicking the action of endogenous ligands or blocking the receptor activity to bring about a modified response. Nearly 35% of approved drugs target the G...

Cognitive Enhancers: Cholinesterase Inhibitors and NMDA Receptor Antagonists

Cognitive enhancers, also known as "smart drugs," are substances used to enhance memory, mental alertness, and concentration. These can be natural or synthetic and improve cognition in conditions like Alzheimer's disease (AD) and other neurodegenerative diseases. Some common examples include caffeine, amphetamines, methylphenidate, modafinil, arecoline, donepezil, vortioxetine, and piracetam. These enhancers work on the principle of synaptic plasticity and altered circuit function. They...
Drugs Affecting Neurotransmitter Synthesis01:29

Drugs 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...

Neurochemical 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...
