Research Overview
Kahalalide F
Kahalalide F was investigated in multiple preclinical and early clinical cancer studies because of its unusual membrane-disrupting and anti-tumor effects. Development highlighted the promise and limits of marine depsipeptides as oncology leads.
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.
