(3Z)-1,3-butadiene-1,1,2,4-tetrol
competitive inhibitor identified by rational design, calculated to be no substrate and not inhibitory to CYP450 and nontoxic in AMES test
(Z)-3-[4-hydroxy-1-(hydroxymethyl)cyclohexyl]-2-propene-1,2-diol
competitive inhibitor identified by rational design, calculated to be no substrate and not inhibitory to CYP450 and nontoxic in AMES test
Dichloroacetate
-
the sensitivity to the inhibitor varies between enzyme haplotypes. Three nonsynonymous single-nucleotide polymorphisms of GSTz1/MAAI show different activity toward dichloroacetate and certain other xenobiotic haloacids
Dichloroacetic acid
-
DCA
GSSG
-
-
iodoacetate
-
-
maleylacetone
-
inhibits isomerization of 6-oxo-2(E),4(Z)-heptanedienoic acid into 6-oxo-2(Z),4(E)-heptanedienoic acid, and the reverse reaction
N-Hexylmaleamic acid
-
noncompetitive towards GSH and maleylacetone
NaBH4
-
inhibition in absence of substrate, increases activity in presence of substrate and GSH
S-Glutathioyl-N-hexylmaleamate
-
competitive towards GSH, uncompetitive towards maleylacetone
S-Methylglutathione
