Description: UNBS-1450, also known as UBS-1450, is a sodium channel antagonist potentially for the treatment of cancer. UNBS-1450 is a hemi-synthetic cardenolide derived from 2″-oxovorusharin extracted from the plant Calotropis procera, which is effective against various cancer cell types with an excellent differential toxicity. At low nanomolar concentrations, UNBS-1450 induces apoptotic cell death. UNBS-1450 inhibits NF-κB transactivation and triggers apoptosis by cleavage of pro-caspases 8, 9 and 3/7, by decreasing expression of anti-apoptotic Mcl-1 and by recruitment of pro-apoptotic Bak and Bax protein eventually resulting in cell death.
