Erbulozole (R 55104) is a potent synthetic microtubule inhibitor with anti-invasive, anti-tumor, and radiosensitizing activities that induces Wernicke's encephalopathy-like neurotoxicity.

Ac-Ile-Glu-Thr-Asp-pNA is a substrate for caspase-8.Caspase-8 binds to and cleaves the Ile-Glu-Thr-Asp (IETD) peptide sequence to release p-nitroalinide, which can be quantified by colorimetric detection at 405 nm as a measure of enzyme activity.

AB-680 is a highly potent, reversible, and selective inhibitor of CD73 (an ectonucleotidase, Ki: 4.9 pM for hCD73) with anti-tumor activity.
