15-Acetoxyscirpenol, a member of the acetoxyscirpenol moiety mycotoxins (ASMs), potently induces apoptosis and inhibits the growth of Jurkat T cells in a dose-dependent manner. This effect is mediated through the activation of caspases independent of caspase-3[1].
UNBS-1450 is a sodium channel antagonist. UNBS-1450 is a hemi-synthetic cardenolide derived from 2″-oxovorusharin, it is effective against various cancer cell types with an excellent differential toxicity. At low nanomolar concentrations, UNBS-1450 induce
CAY10406 is a trifluoromethyl analog of an isatin sulfonamide compound that selectively inhibits caspases 3 and 7. The non-trifluoromethyl compound exhibits Ki values of 1.2 nM and 6 nM for caspases 3 and 7, respectively. For all of the other caspases tested, it is 100 to 1,000 times less potent. Caspases 3 and 7 are 'effector caspases' that are downstream from the initiating steps of apoptosis, and are implicated in the main proteolytic processing of the apoptotic signal. No data is currently available for caspase inhibition by CAY10406.
