Alzheimer's disease drug discovery targeted to the APP mRNA 5'untranslated region

J Mol Neurosci. 2002 Aug-Oct;19(1-2):77-82. doi: 10.1007/s12031-002-0014-6.

Abstract

We performed a screen for drugs that specifically interact with the 5' untranslated region of the mRNA coding for the Alzheimer's Amyloid Precursor Protein (APP). Using a transfection based assay, in which APP 5'UTR sequences drive the translation of a downstream luciferase reporter gene, we have been screening for new therapeutic compounds that already have FDA approval and are pharmacologically and clinically well-characterized. Several classes of FDA-pre-approved drugs (16 hits) reduced APP 5'UTR-directed luciferase expression (> 95% inhibition of translation). The classes of drugs include known blockers of receptor ligand interactions, bacterial antibiotics, drugs involved in lipid metabolism, and metal chelators. These APP 5'UTR directed drugs exemplify a new strategy to identify RNA-directed agents to lower APP translation and A beta peptide output for Alzheimer's disease therapeutics.
