Research Overview
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.
Conantokin-G
Research has shown conantokin-G can suppress NMDA-mediated responses in a sequence- and modification-dependent manner. It remains a classic marine peptide tool for probing glutamatergic signaling and analgesia-related pathways.
