Biological Activity

Alda-1 is a potent and selective Aldehyde Dehydrogenase-2 Agonist. Alda-1 increases activity of wild-type ALDH2*1 and variant ALDH2*2 (by ~2-fold and 11-fold respectively). Alda-1 reverses alcohol-induced hepatic steatosis and cell death in mice. Alda-1 inhibits atherosclerosis and attenuates hepatic steatosis in apolipoprotein E-knockout mice. Alda-1 reduces cerebral ischemia/reperfusion injury in rat through clearance of reactive aldehydes.

Alda-1 (8.5 mg/kg, i.p.) with glucose significantly lowers 4-HNE and FJB-positive cells in the cerebral cortex of Alda-1-treated rats than in DMSO-treated rats 24 h after glucose administration. Alda-1 (10 mg/kg per day) treatment prevents aldehydic overload, mitochondrial dysfunction and improves ventricular function in post-MI cardiomyopathy rats.

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
