Small molecule activator of ALDH2 (EC50 value ca 6 μM for ALDH2 mediated acetaldehyde metabolism) with the ability to activate wild-type ALDH2 and restore near-wild-type activity to ALDH2*2. When administered to rats before an ischemic event, Alda 1 reduced infarct size by 60%, most likely through its inhibitory effect on the formation of cytotoxic aldehydes. Alda-1 was effective in protecting against rotenone-induced apoptotic cell death in both SH-SY5Y cells and primary cultured substantia nigra (SN) dopaminergic neurons, and significantly reduced rotenone- or MPTP-induced death of SN tyrosine hydroxylase (TH)-positive dopaminergic neurons.
