Description

14-aryl ethers Herba Andrographis Inner ester derivative and its production and application
Technical field
The invention belongs to the pharmaceutical chemistry field, be specifically related to a kind of 14-aryl ethers andrographolidume derivative, steric isomer, cis-trans-isomer or the preparation of its pharmacy acceptable salt and application pharmaceutically.These compounds by regulating nuclear receptor FXR function or be used for treatment and prophylaxis of tumours, diabetes and obesity and other metabolic disease, cardiovascular pathological changes, reproductive system disease by other identical, the similar or different action target or the mechanism of action, immunological disease, inflammation, comprise senile dementia and Parkinson disease and other neurological disorder class disease, be used for reducing cholesterol and blood fat, and the AIDS that causes of the disease that causes of treatment and prevention yellow fever virus caused singapore hemorrhagic fever, hepatitis C, West Nile Virus infection and HIV.
Background technology
Nuclear receptor (Nuclear receptor or title Nuclear hormone receptor, abbreviation NHR) being that a class is present in tenuigenin or nucleus is interior also can spread and the interior signal protein of ligands specific (ligand) bonded cell, thereby regulate important vital process (the Handschin C of endocellular sugar metabolism, lipid metabolism, energy transformation and immunne response with the transcriptional regulator that is subjected to physical efficiency to combine the formation ligand-dependent with the DNA response element after part combines

S, Roth A, Looser R, Oscarson M, Kaufmann MR, Podvinec M, Gnerre C, Meyer UA Nucl Recept2004,2,7.), therefore they are bringing into play keying action (Evans RM Mol Endocrinol2005 in cell proliferation, cytodifferentiation and cell internal and external equilibrium, 19,1429-1438.), in vital processes such as reproduction, growth and metabolism, play important regulation (Robinson-Rechavi M, Escriva GH, Laudet V J Cell Sci2003,116,585-586.).
(Farnesoid X Receptor is one of nuclear hormone receptor superfamily member FXR) to method Buddhist nun's ester derivative X acceptor, has typical NHR family structure.The present FXR that discovers plays the part of vital role in processes such as regulation and control bile acide, lipoprotein and glucose metabolism, liver regeneration, intestinal bacteria growth and hepatotoxin responsing reaction.In liver, cholesterol is formed bile acide by metabolism, and bile acide not only can be used as the physiology solvent to help absorption, transhipment and the distribution of liposoluble vitamin and fat, can also regulate bile acide and cholesterol metabolic to activate FXR as signaling molecule.Therefore, synthetic and screening can be regulated and control the new drug that the active compound of FXR will help developing the treatment metabolic disease.
Nuclear receptor plays a role jointly with action target COX (cyclooxygenase) enzyme family of non-steroidal anti-inflammatory drugs (NSAID is nonsteroidal anti-inflammatory drug) sometimes, as nuclear receptors PPAR's δ, RAR, RXR and COX-2 the variation of expression (Delage B is arranged all in colorectal carcinoma, Rullier A, Capdepont M, Rullier E, Cassand P Nutrition Journal2007,6,20); Cholic acid in stomach cancer cell (bile acid) can induce COX-2 expression (Park MJ, Kim KH, Kim HY, Kim K, Cheong J Carcinogenesis2008,29 (1), 2385-2393); Nuclear receptor Nur77 suppresses to depend on the inflammatory reaction (Shao Q, Shen LH, Hu LH, Pu J, Qi MY, Li WQ, Tian FJ, Jing Q, He B J.Molecular Cellular Cardiology2010,49 (2), 304) of COX-2; RXRa mediation Ibuprofen BP/EP class NSAID medicine to the beta amyloid material of Alzheimer disease (effect of β-amyloid) (and You X, Zhang YW J Neurochemistry2009,111,142-149.); Nuclear receptors PPAR's g is activated (Bernardo A, Ajmone-Cat MA, Gasparini L by flurbiprofen class NSAID medicine HCT1026 in the rat microgliacyte, Ongini E, Minghetti L J Neurochem.2005,92 (4), 895-903.).
The reductase enzyme reduction reaction of HMG-CoA reductase enzyme (hydroxymethylglutaryl-coenzyme A reductase, HMG-CoA reductase) is that cholesterol synthetic rate determining step is rapid.On the one hand, consider that from chemical structure rographolide and HMG-CoA reductase inhibitor-fungal metabolite lovastatin (Lovastatin) or its semi-synthetic derivative Simvastatin (Simvastatin), Pravastatin (Pravastatin) have certain space structure similarity, so rographolide and derivative thereof may have the function of inhibition HMG-CoA reductase enzyme; On the other hand, many nuclear receptors and endogenic ligand thereof are participated in the cholesterol biosynthetic process, so rographolide and derivative thereof also may suppress the biosynthesizing of cholesterol by other mechanism.
