COMPOUNDS FOR INHIBITING DISEASES AND PREPARING CELLS FOR TRANSPLANTATION

摘要

Methods and compositions are provided for inhibiting, preventing and treating amyloid depositions, e.g. in pancreatic islets, wherein the amyloidotic deposits are islet amyloid polypeptide (IAPP)-associated amyloid deposition or deposits. Accordingly, the compositions and method of the invention are useful for inhibiting diabetes. The invention also provides a process for the preparation of cells suitable for transplantation into a mammal, which cells are capable of forming fibrils, said process comprising contacting the cells with an inhibitor of fibril formation. In particular the process prepares cells for use in a method of treating diabetes. Also provided are a culture medium comprising the inhibitor more particularly selected from the group consisting of 3-(3-hydroxy-1-propy)amino-1-propanesulfonic acid; DL-2-amino-5-phosphovaleric acid; 4-Phenyl-1-(3'-sulfopropyl)-1,2,3,6-tetrahydropyridine, cyclohexylsulfamic acid, O-phospho-L-serine, hexafluoroglutaric acid, 8-methoxyquinoline-5-sulfonic acid, 3-amino-2hydroxy-1-propanesulfonic acid, and 3-dimethylamino-1-propanesulfonic acid and 1,2,3,4-tetrahydroisoquinoleine.
