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.

Apratoxin A

Apratoxin A is a well-studied lead compound for targeting secretory and membrane protein biogenesis in cancer cells. Medicinal chemistry programs around apratoxins focus on improving selectivity and reducing hepatotoxicity while preserving potency.
