AC 187 TFA is a potent and orally active amylin receptor antagonist with an IC₅₀ of 0.48 nM and a K_i of 0.275 nM. AC 187 TFA shows more selective for amylin receptor than calcitonin and CGRP receptors. AC 187 TFA has neuroprotective effects^[1][2].

IC50: 0.48 nM (amylin receptor)

AC 187 blocks amyloidβ protein (Aβ)-induced neurotoxicity. Treatment of cultures with AC 187 before exposure to Aβ results in significantly improved neuronal survival^[1].
AC187 attenuates the activation of initiator and effector caspases that mediate Aβ-induced apoptotic cell death^[1].

AC 187 (30 mg/mL) increases glucagon concentration, accelerates gastric emptying of liquids, and results in an exaggerated post-challenge glycemia in hyperinsulinemic clamps in Sprague-Dawley (HSD) rats^[2].
