Research Overview
Plitidepsin
Plitidepsin has been studied for its ability to disrupt eEF1A-dependent pathways, induce oxidative stress, and suppress tumor cell growth. It has reached clinical oncology development and was also evaluated as a candidate against SARS-CoV-2 in the literature.
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.
