SPD304 is a selective TNF-α inhibitor, which promotes dissociation of TNF trimers and therefore blocks the interaction of TNF and its receptor. SPD304 has an IC50 of 22 µM for inhibiting in vitro TNF receptor 1 (TNFR1) binding to TNF-α.

How to use

In Vitro:

SPD304 (2 μM) significantly rescues the survivability of aHSCs, reduces the production of lipid hydroxides, and increased intracellular GSH. The co-treatment of GA (75 μM) and SPD304 (2 μM), down-regulate TRADD almost 2-fold (w/o inhibitor vs. w/ inhibitor) and p−RIP3 1.4−fold compared to GA alone, and promotes caspase 8 activation.

In Vivo:

SPD304 cannot be used in vivo due to its high toxicity.
