4-Bromo-3-hydroxybenzoic acid
4-Bromo-3-hydroxybenzoic acid is a metabolite of Brocresine and a histidine decarboxylase (HDC) inhibitor with IC50s of 1 mM for both rat fetal and rat gastric HDC. 4-Bromo-3-hydroxybenzoic acid also inhibits aromatic-L-amino acid decarboxylase from hog kidney and rat gastric mucosa in vitro with IC50s of 1 mM for both enzymes.
