Research Overview

RgIA

Scientific studies show RgIA can strongly inhibit alpha9alpha10 nicotinic signaling with high selectivity compared with many other nAChR ligands. It is widely used to probe peripheral sensory pathways and inflammation-linked pain mechanisms.

Mambalgin-1

Pre-clinical work shows mambalgin-1 can reduce pain behaviors by modulating proton-gated ion channels in peripheral and central pathways. It has become an important template for developing ASIC-targeted analgesics.
