Description

White solid

N-ethylmaleimide is a member of the class of maleimides that is the N-ethyl derivative of maleimide. It has a role as an EC 2.1.1.122 [(S)-tetrahydroprotoberberine N-methyltransferase] inhibitor, an EC 2.7.1.1 (hexokinase) inhibitor, an EC 1.3.1.8 [acyl-CoA dehydrogenase (NADP(+))] inhibitor and an anticoronaviral agent. It derives from a maleimide.|A sulfhydryl reagent that is widely used in experimental biochemical studies.
