PRODUCT INTRODUCTION
description
PYR-41 is an ethyl ester resulting from the formal condensation of the carboxy group of 4-{4-[(5-nitrofuran-2-yl)methylidene]-3,5-dioxopyrazolidin-1-yl}benzoic acid with ethanol. It is an irreversible and cell-permeable inhibitor of ubiquitin-activating enzyme E1. It has a role as an EC 6.2.1.45 (E1 ubiquitin-activating enzyme) inhibitor and an antineoplastic agent. It is an ethyl ester, a member of furans, a C-nitro compound, a member of pyrazolidines and a benzoate ester.
