The present disclosure relates to amyloid beta (Aβ) channels and the diseases and disorders caused by abnormal activity in these channels, such as Alzheimer's disease, Lewy body dementia, inclusion body myositis, or cerebral amyloid angiopathy. The disclosure provides compositions and methods that block Aβ channel activity and/or reduce Aβ-induced toxicity in a cell. Compositions comprised of compounds having histidine coordinating capacity are used in methods to prevent, reduce, or eliminate damage caused by Aβ ion channels.

Novel thiazolidine derivatives which are useful as drugs. These thiazolidine derivatives are compounds represented by general formula (I) and salts thereof wherein R1 represents alkyl, hydroxy, alkoxy, alkoxyalkyl, phenyl, phenylalkyl, phenylalkoxy, phenoxy, phenoxyalkyl, amino, alkylamino or a non-aromatic heterocycle; R2 represents H or alkyl; R3 represents H, alkyl or phenyl; R4 represents H or alkyl; R5 represents alkyl, halogenoalkyl, hydroxy, alkoxy, phenyl, phenylalkoxy, phenoxy, carboxy, alkoxy, carbonyl, phenylalkoxycarbonyl or heteroaryl; A1 represents alkylene; and A2 represents alkylene.
摘要:
The invention is directed to methods and compositions for chemical ligation of components comprising a first component having a carboxythioester, and preferable an alpha -carboxythioester, moiety and a second component having an N-substituted, and preferably an N alpha -substituted, 2 or 3 carbon chain alkyl or aryl thiol to give a ligation product having an N-substituted amide bond at the ligation site. The reactants of the invention are chemoselective, and the alkyl or aryl thiol moiety is removable from the ligation product. Removal of the alkyl or aryl thiol gives a native amide bond at the ligation site. The methods and compositions of the invention are particularly useful for ligation of peptides and polypeptides. The ligation system of the invention is applicable to a wide variety of molecules, and thus can be exploited to generate peptides, polypeptides and other amino acid containing polymers having a native amide bond at the ligation site.
摘要:
The present invention relates to a novel enzyme that allows peptide to be produced easily, inexpensively and at high yield without going through a complex synthesis method. More particularly, the present invention provides a novel enzyme that catalyzes a peptide-producing reaction from a carboxy component and an amine component, a microbe that produces the enzyme, and a method for inexpensive production of peptides using this enzyme or microbe. The novel enzyme that efficiently produces peptide was discovered from a newly discovered microbe belonging to the genus Empedobacter, and a method was found that allows peptides to be produced inexpensively and easily.
