AC253 is an antagonist of Amylin, one of the peptides in the Calcitonin-gene related peptide (CGRP) family. In recent studies. AC253 restored memories in brain cells taken from animals used as models of Alzheimer′s disease. Application of AC253 significantly enhanced long-term potentiation (LTP) when given to 6- to 12-month-old TgCRND8 mice that normally show blunted LTP. In other studies, AC25 neutralized the depressant effects of Aβ(1-42) on hippocampal LTP without affecting baseline transmission or LTP on its own.
