Black-mamba peptides that produce potent analgesia in animals by blocking acid-sensing ion channels.
Also known as: Mamb-1 · pi-Dp1
Part of the Foundational & therapeutic peptides cluster
Overview
Mambalgins are three-finger-toxin peptides isolated from black mamba venom that inhibit acid-sensing ion channels (ASICs) by trapping them in a closed conformation. In rodent studies they produced strong pain relief without the respiratory depression or tolerance associated with opioids, drawing interest as a route to novel, non-opioid analgesic research.

Source & context
Biological / chemical source: Venom of the black mamba (Dendroaspis polylepis)
Primary research or clinical context: Research tool studied for analgesia and ASIC physiology
ASIC-targeting toxins
Discovered in 2012, mambalgins belong to the three-finger-toxin fold common in snake venoms but are unusual in acting on acid-sensing ion channels rather than nicotinic receptors. By stabilizing ASICs in a closed state, they blunt the acidic pain signaling those channels carry in the nervous system.
Analgesia research
In mice, mambalgins produced analgesia comparable to morphine in some assays but without the classic opioid side-effect profile, prompting study of mambalgin-derived peptides and their receptor interactions. They remain experimental molecules used to probe pain pathways, not approved treatments. This page is educational only.
