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.
Mambalgin-1
Pre-clinical work shows mambalgin-1 can reduce pain behaviors by modulating proton-gated ion channels in peripheral and central pathways. It has become an important template for developing ASIC-targeted analgesics.
