Targets for Drug Action: Overview

9.2K
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...

Pharmacogenomics: Identification of New Drug Targets

121
Advances in genomics have profoundly influenced drug discovery by increasing both the speed and accuracy of pharmaceutical development. Pharmacogenomics, which examines how genetic variation influences drug response, facilitates the identification of novel therapeutic targets and enables patient stratification for personalized treatment. These strategies contribute to improved drug efficacy, minimized adverse effects, and more efficient clinical trial design.Mapping genetic differences...

Summary
This summary is machine-generated.

New migraine treatments focus on brain targets rather than blood vessels. Research is advancing compounds for acute and preventive care, offering hope for those unresponsive to current therapies like triptans.

Area of Science:

  • Neurology
  • Pharmacology

Background:

  • Migraine is a common, disabling neurological disorder with complex pathophysiology.
  • Serotonin 5-HT(1B/1D) receptor agonists (triptans) improved acute migraine treatment but have limitations.
  • Many patients are unresponsive to triptans, and cardiovascular issues restrict their use.

Purpose of the Study:

  • To review emerging pharmacological targets and compounds for migraine treatment.
  • To highlight treatments focusing on neural mechanisms rather than vasodilation.
  • To discuss compounds in clinical trials for acute and preventive migraine therapy.

Main Methods:

  • Review of preclinical and clinical data on novel migraine drug targets.
  • Focus on compounds acting on calcitonin gene-related peptide (CGRP) pathway.
  • Evaluation of agents targeting 5-HT(1F) receptors, nitric oxide synthase, and acid-sensing ion channels.

Main Results:

  • Significant advances in understanding migraine pathophysiology over 20 years.
  • Development of neurally acting compounds lacking vasoconstrictor properties.
  • Identification of promising targets like CGRP, 5-HT(1F) receptors, and others for clinical trials.

Conclusions:

  • Migraine is increasingly viewed as a brain disorder, with vasodilation as an epiphenomenon.
  • Novel pharmacological targets offer potential for improved acute and preventive migraine treatments.
  • Compounds targeting CGRP, 5-HT(1F) receptors, and other neural pathways show promise.
