  • Patent number: 5266561
    Abstract: Compounds and methods for blocking the effects of diabetes-associated peptide, or "amylin", a hormone found in the amyloid masses of Type 2 diabetics. This putative hormone has been discovered to function both to inhibit insulin secretion and to inhibit glycogen synthesis. Regulation is accomplished by blocking the binding of amylin or amylin agonists, including calcitonin gene related peptide (CGRP], or biologically active sub-peptides thereof. Inhibitors include substituted peptides or sub-peptides of amylin or CGRP, cross-linked amylin and amylin agonists, synthetic amylin, anti-amylin receptor antibodies and anti-idiotype antibodies, and antibodies directed to amylin and amylin agonist active sites. Other antagonists include organic compounds which can be screened and assayed for anti-amylin effects by disclosed methods.
