| 4[4-(5-nitro-furan-2-ylmethylene)-3,5-dioxo-pyrazolidin-1-yl]-benzoic acid ethyl ester | i.e. Pyr-41. Inhibitor blocks loading of immobilized His6-tagged E1 with ubiquitin. PYR-41 does not affect the transfer of ubiquitin to E2 from E1 that is preloaded with ubiquitin, it directly inhibits E1, but not E2 enzymes. In addition to blocking ubiquitylation, PYR-41 increases total sumoylation in cells. PYR-41 attenuates cytokine-mediated nuclear factor-kappaB activation. This correlates with inhibition of nonproteasomal Lys63 ubiquitylation of TRAF6, which is essential to IkappaB kinase activation | Homo sapiens | |
| 4[4-(5-nitro-furan-2-ylmethylene)-3,5-dioxo-pyrazolidin-1-yl]-benzoic acid ethyl ester | i.e. PYR-41, potential of the inhibitor as therapeutic in cancer | Mus musculus |
