Inhibitors

EC Number Inhibitors Comment Organism Structure
2.4.1.80 ethyl-2-amino-6-bromo-4-(1-cyano-2-ethoxy-2-oxoethyl)-4H-chromene-3-carboxylate i.e. HA14-1, a reversible small molecule Bcl-2 inhibitor that also inhibits GlcT-1 enzyme activity. HA14-1 is a competitive and mixed-type inhibitor with respect to C6-NBD-ceramide and UDP-glucose, respectively. HA-14 does not possess structural homology with the substrates UDP-glucose and ceramide. Possible binding of GlcT-1 to Bcl-2 Homo sapiens

General Information

EC Number General Information Comment Organism
2.4.1.80 additional information the use of ethyl-2-amino-6-bromo-(1-cyano-2-ethoxy-2-oxoethyl)-4H-chromene-3-carboxylate, i.e. HA14-1, as a Bcl-2 inhibitor in studies of apoptosis might produce misleading results, because HA14-1 can also affect a ceramide-mediated cell death pathway by inhibiting GlcT-1. Bcl-2 is a protein factor known to suppress apoptosis by binding and inactivating pro-apoptotic proteins such as Bax and BH3-only family proteins Homo sapiens
