Abstract
Certain peptide molecules can be used as the basic structures (template molecules) for inhibiting and analysing amyloid formation and cytotoxicity in amyloid illnesses. These peptides have an effect on the molecules which are responsible for the amyloid illnesses (for their part amyloid-forming peptides and proteins). The peptides are thus either inhibitors themselves or agonists of amyloid formation and cytotoxicity or can serve as a template for identifying and producing further inhibitors and agonists and can be used as molecular tools during analysis. The peptide molecules have generally 3-15 amino acids, and preferably a maximum of 10 amino acids, and at least an active peptide sequence GA, preferably GAI, and even more preferably one selected from the group consisting of GAIL, SEQ ID NO: 1; FGAIL, SEQ ID NO: 2; NFGAIL, SEQ ID NO: 3; NNFGAIL, SEQ ID NO: 4; SNNFGAIL, SEQ ID NO: 5; NFGAILSS, SEQ ID NO: 6; SNNFGAILSS, SEQ NO: 7; or the group consisting of GAII, SEQ ID NO: 8; KGAII, SEQ ID NO: 9; NKGAII, SEQ ID NO: 10; SNKGAII, SEQ ID NO: 11; GSNKGAII, SEQ ID NO: 12; NKGAIIGL, SEQ ID NO: 13; GSNKGAIIGL, SEQ ID NO: 14; or the group consisting of GAVV, SEQ ID NO: 15; AGAVV, SEQ ID NO: 16; VAAGAVV, SEQ ID NO: 17; HVAAGAVV, SEQ ID NO: 18; AAGAVVGG, SEQ ID NO: 19; HVAAGAVVGG, SEQ ID NO: 20; AAGAVV, SEQ ID NO: 21. The peptide sequence generally has at least one hydrogen molecule, and preferably every second hydrogen molecule, of an amide bond replaced by a methyl group.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
