Research Overview
Didemnin B
Didemnin B showed strong cytotoxic and antiviral activity in early literature and became an important scaffold for later marine drug development. Its clinical progress was limited by toxicity, but it remains highly cited as a foundational marine depsipeptide.
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.
