Cat.No. 6550 - AC 253 | Ac-Leu-Gly-Arg-Leu-Ser-Gln-Glu-Leu-His-Arg-Leu-Gln-Thr-Tyr-Pro-Arg-Thr-Asn-Thr-Gly-Ser-Asn-Thr-Tyr-NH2 | CAS No. 151804-79-4
Description: Amylin (AMY3) antagonist
Literature (3)

Biological Activity

Amylin (AMY3) receptor antagonist. Inhibits andrenomedulin-stimulated cAMP production in vitro. Protects against oligomeric Aβ-induced increase in intracellular Ca2+, activation of PKA, MAPK, Akt and cFOS and cell death in neuronal cell culture. Blocks electrophysiological effects of Aβ in vitro. Cyclic AC 253 (Cat.No. 6550) also available.
