Research Overview
Dolastatin 10
Dolastatin 10 became famous for extreme cytotoxic potency and its ability to block tubulin polymerization. Although the native compound itself did not become a standard therapy, it inspired a major class of clinically important auristatin-based payloads.
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.
