Invention field
The present invention relates to a heterocyclic class tertiary carbon amine (tertiary carbinamines), and relate to the treatment of the Ji Bingliruaercihaimoshi disease that wherein relates to beta-secretase with replacement as beta-secretase inhibitor.
Background of invention
Alzheimer is characterised in that the amyloid abnormal deposition that exists with neurofibrillary tangles form in outer speckle of born of the same parents and the born of the same parents in the brain.The speed that amyloid is accumulated is the combination that forms, assembles and overflow speed in brain.General acceptable be that the main component of amyloid speckle is 4kD amyloid (β A4 also is referred to as A β, beta-protein and β AP), the latter is the protein hydrolysate of the precursor protein of more volume.Amyloid precursor protein (APP or A β PP) has the receptor spline structure, and this structure has big extracellular domain, strides film district and short kytoplasm tail (short cytoplasmic tail).A beta structure territory comprises outer and two parts of membrane spaning domain of born of the same parents of APP, so its release means two different Proteolytic enzyme activities of existence, to generate its NH
2-and the COOH-end.At least there are two mechanism of secretion, the APP (APPs) that it discharges APP and generate the COOH-clipped form of solubility from film.Be referred to as " secretase " from film release APP and segmental protease thereof.Most of APPs discharge by the alpha-secretase enzyme of generally acknowledging, its cracking in a and stops and discharges complete A β discharging α-APPs.The APPs of fraction discharges by beta-secretase (" beta-secretase "), and it is at the NH of contiguous APP
2Terminal cracking and generation contain the COOH-terminal fragment (CTFs) in whole A beta structure territory.
Therefore, the activity of beta-secretase or β-site amyloid precursor protein lyases (" BACE ") causes unusual APP cracking, the A β in the brain to produce and the amyloid beta speckle is assembled, it is that the feature of Alzheimer is (referring to R.N.Rosenberg, Arch.Neurol., the 59th volume, in JIUYUE, 2002, the 1367-1368 page or leaf; H.Fukumoto etc., Arch.Neurol., the 59th volume, in JIUYUE, 2002,1381-1389 page or leaf; J.T.Huse etc., J.Biol.Chem., the 277th volume, the 18th phase, on May 3rd, 2002 published, the 16278-16284 page or leaf; K.C.Chen and W.J.Howe, Biochem.Biophys.Res.Comm, the 292nd volume, 702-708 page or leaf, 2002).Therefore, the medicine that can suppress beta-secretase or BACE can be used for the treatment of Alzheimer.
Chemical compound of the present invention passes through to suppress the activity of beta-secretase or BACE, thereby prevents insoluble A β to form and stop the generation of A β, can be used for treating Alzheimer.
The invention summary
