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.

Dolastatin 10

Dolastatin 10 became famous for extreme cytotoxic potency and its ability to block tubulin polymerization. Although the native compound itself did not become a standard therapy, it inspired a major class of clinically important auristatin-based payloads.
