Description_x000D_ Packaging_x000D_ 5, 25 mg in glass bottle_x000D_ Biochem/physiol Actions_x000D_ Alda-1 is an ALDH2 agonist; cell-permeable activator of both the wild-type ALDH2*1 and the asian E487K mutant ALDH2*2 forms of mitochondrial aldehyde dehydrogenase 2. ALDH2 is the oxidative enzyme, which removes the ethanol metabolite acetaldehyde and other aliphatic aldehydes. Also. ALDH2 is involved in bioconversion of vasodilator nitroglycerin to nitric oxide. Alda-1 increases acetaldehyde oxidation by ALDH2*1 (wild type) and ALDH2*2 9 Asian variant) approximately 1.5- and 6-fold, respectively. It appears that Alda-1 stimulates acetaldehyde oxidation by ALDH2 by improving NAD binding, but does not improve the nitroglycerin binding affinity of the Asian variant.
