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

381
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...

Area of Science:

  • Neuroscience
  • Pharmacology
  • Biochemistry

Background:

  • Voltage-gated sodium channels (Nav1.7) are crucial for pain signal transmission in the nervous system.
  • Nav1.7 gain-of-function mutations cause pain, while loss-of-function mutations lead to pain insensitivity.
  • Nav1.7 is a key target for developing new pain relief medications, but selective drugs are still lacking.

Purpose of the Study:

  • To summarize research efforts in developing Nav1.7 selective antagonists.
  • To explore the potential of engineering spider venom peptides as analgesics.

Main Methods:

  • Reviewing studies on spider venom peptide scaffolds targeting Nav1.7.
  • Analyzing progress and challenges in developing venom-based Nav1.7 inhibitors.

Main Results:

  • Spider venom peptides offer promising scaffolds for Nav1.7 antagonist development.
  • Progress has been made using various venom families.

Conclusions:

  • Engineering spider venom peptides is a viable strategy for creating Nav1.7 selective analgesics.
  • Further research is needed to overcome challenges in developing these venom-based therapeutics.
