Abstract
The invention discloses 4', 5-dyhydroxyl-7-(4-(N, N-diethylamino group) butoxy) isoflavone of dye lignin derivative, a preparation method and an application of the 4', 5-dyhydroxyl-7-(4-(N, N-diethylamino group) butoxy) isoflavone. The 4', 5-dyhydroxyl-7-(4-(N, N-diethylamino group) butoxy) isoflavone obtained by chemically modifying the dye lignin derivative has the acetylcholinesterase inhibition activity, the estrogen activity and the nerve cell protective action; and the 4', 5-dyhydroxyl-7-(4-(N, N-diethylamino group) butoxy) isoflavone which is taken as a multi-function target spot can be used for preparing the alzheimer disease-resistant medicament.
Description
Technical field
The present invention relates to a kind of genistein verivate, specifically, relate to 4 ', 5-dihydroxyl-7-[4-(N, N-diethylin) butoxy] NOVASOY 400.
Background technology
Alzheimer's disease is a kind of common senile cranial nerve degeneration, and sickness rate is higher, has become one of disease of modern society serious threat the elderly life and health.The typical pathological change of this disease comprises
βAmyloid beta deposition forms senile plaque; Neurofibrillary tangles; The change of neuron loss and cynapse form widely of basal forebrain cholinergic function obstacle and cortex, hippocampus (referring to: Roberson ED, Mucke L. 100 years and counting:prospects for defeating Alzheimer's disease. Science 2006; 314 (5800): 781-4).
The pathology of discovering patients with Alzheimer disease brain endodermis and hippocampus is apparent in view, and former basal ganglia cholinergic neuron destroys at most.Therefore, through the content of increase vagusstoff, or act on cholinocepter; The function of central cholinergic system be can strengthen and improve, thereby purpose (Baskin DS, Browning JL that short intelligence is cured the disease reached; Pirozzolo FJ; Korporaal S, Baskin JA, Appel SH. Brain choline acetyltransferase and mental function in Alzheimer disease. Archives of Neurology 1999; 56 (9): 1121-3).Acetylcholinesterase depressant is exactly to be based upon the most sophisticated the earliest one type of medicine that is used for treatment of alzheimer clinically (the Taylor P. Development of acetylcholinesterase inhibitors in the therapy of Alzheimer's disease. Neurology 1998 that develops on this theoretical basis; 51 (Supplement 1), S30 – S35), such medicine can make its cognitive function and other symptom obtain part and improve light, moderate Alzheimer's disease patient's determined curative effect.Present multiple acetylcholinesterase depressant has been used for the treatment of alzheimer's disease.
But E.C. 3.1.1.7 suppresses the integrated degree that the curative effect of type medicine depends on cholinergic neuron, is inappropriate for the severe patient.Simultaneously; Such medicine can only improve the content of vagusstoff, and what can not stop cholinergic nerve of centrum unit carries out sexual involution death, along with the development of the state of an illness; Cholinergic nerve of centrum unit carries out sexual involution death, and the drug effect of acetylcholinesterase depressant also can reduce gradually.Therefore, searching can stop the dead novel acetylcholinesterase depressant of cholinergic nerve of centrum unit degeneration to become the key of seeking therapeutic agent for alzheimer's disease again by acetylcholine esterase inhibition activity.
βAmyloid is piled up the formation that has caused senile plaque; The neurotoxicity approach that promoted the inflammatory reaction activation has caused the dysfunction and the death of neurocyte, is to form senile plaque; Cause one of the main reasons (the Riviere C of neurocyte degeneration; Richard T, Vitrac X, Merillon JM; Valls J, Monti JP. New polyphenols active on beta-amyloid aggregation. Bioorganic and Medicinal Chemistry Letters 2008; 18 (2): 828-31).Research shows that oestrogenic hormon can suppress
βAmyloid inductive nerve cell death has good neurocyte protection effect.But oestrogenic hormon causes the non-neurocyte that oestrogenic hormon is relevant such as the hyperplasia and the canceration of mammary gland cell and endometrial cell during alzheimer's disease in treatment; Therefore in clinical application, be restricted (Bang OY, Hong HS, Kim DH; Kim H; Boo JH, Huh K, et al. Neuroprotective effect of genistein against beta amyloid-induced neurotoxicity. Neurobiology of Disease 2004; 16 (1): 21-8).
Genistein (4 ', 5, the 7-trihydroxy-isoflavone) is the main biologically active substance of soybean isoflavones, and this compound has stronger estrogen activity.Research shows that genistein can either suppress
βAmyloid inductive nerve cell death can not cause Normocellular canceration again as oestrogenic hormon, in the treatment of alzheimer's disease, have good application prospects.But this compound does not have inhibiting activity of acetylcholinesterase,, and its application receives certain restriction.
The incidence and development of considering alzheimer's disease is caused by a plurality of factors; " multi-target-directed drug design strategy " (i.e. design concept that compound molecule can act on a plurality of targets in the development of Alzheimer's disease mutually) is introduced into (Bolognesi ML in the research and development of therapeutic agent for alzheimer's disease; Cavalli A; Valgimigli L; Bartolini M; Rosini M, Andrisano V, et al. Multi-target-directed drug design strategy:from a dual binding site acetylcholinesterase inhibitor to a trifunctional compound against Alzheimer's disease. Journal of Medicinal Chemistry 2007; 50 (26): 6446-9).The therapeutic agent for alzheimer's disease that can act on a plurality of target spots has simultaneously become the trend of alzheimer's disease medicament research and development.Genistein is carried out chemically modified, and the multiple acting target spot compound that is had estrogen activity and inhibiting activity of acetylcholinesterase, simultaneously will have good application prospects in treatment of alzheimer.
Summary of the invention
