Abstract
The present invention relates to SSAO inhibitor fields.Specifically, the present invention relates to a kind of SSAO inhibitor containing methyl adamantane and dimethylaminopyridine class formation, preparation method and the applications in treatment diseases associated with inflammation, immunity disease and tumour etc. is prepared.
Description
Technical field
The present invention relates to the fields of SSAO inhibitor.In particular it relates to inhibiting SSAO that there is therapeutic effect
A kind of noval chemical compound containing methyl adamantane and dimethylaminopyridine structure, preparation method and the purposes in pharmacy.
Background technology
Semicarbazide-sensitive amine oxidizing ferment (semicarbazide-sensitive amine oxidase, SSAO) activity
It is by Vascular AdhesionProtein -1 (Vascular Adhesinon Protein-1, VAP-1) or copper-containing amine oxidases (Amone
Oxidase, Copper Containing 3, AOC3) enzymatic activity that is showed, the enzyme belongs to copper-containing amine oxidases family
(EC.1.4.3.6).Therefore, the biological function of VAP-1 albumen is also adjusted in the inhibitor of SSAO enzymes.The member of the enzyme family
It is sensitive to the inhibition of semicarbazides, and by bivalent cupric ion and from protein hydroxydopa quinone (topa quinine,
TPQ) co-factor is for from primary amine to aldehyde, the oxidative deamination of hydrogen peroxide and ammonia.
The known substrate of people SSAO includes endogenous methylamine and aminoacetone and some exogenous amine such as benzylamines
(Lyles, Int.J.Biochem.Cell Biol., 1996,28,259-274).It is similar with other copper-containing amine oxidases, DNA sequences
Row analysis and structure determination show and the people SSAO that organizes to combine is homodimeric glycoprotein, by two 90-100kDa's
Subunit forms, by single N-terminal transmembrane domain be anchored to plasma membrane (Morris, et al.J.Biol.Chem., 1997,272,
9388-9392)。
It has been found that SSAO activity in Various Tissues (including blood vessel and non-vascular smooth muscle tissue, endothelium and adipose tissue)
(Lewinsohn,Braz.J.Med.Biol.Res.,1984,17,223-256).In addition, SSAO albumen also found in blood plasma
And this soluble form seem with tissue combining form have similar performance (Kurkijarvi, et al.J.Immunol.,
1998,161,1549-1557).Recently it has been shown that SSAO derives from tissue combining form in the cycle of people and rodent
(Stolen,et al.Circ.Res.,2004,95(1),50-57)。
The precise physiological effect of this abundant enzyme is not yet fully defined, but seems SSAO and its reaction product thin
There may be several functionalities in born of the same parents' signal transduction and adjusting.For example, nearest discovery shows the glucose that SSAO is mediated in GLUT4
Absorb (Morin, et al.J.Pharmacol.Exp.Ther., 2001,297,563-572) and Adipocyte Differentiation
It all plays a role in (Fontana, Biochem.J., 2001,356,769-777).In addition, SSAO also shows to participate in inflammation mistake
Journey, wherein SSAO serve as leucocyte adhesion protein (Salmi＆Jalkanen, Trends Immunol., 2001,22,211-
216) and be also possible to connective tissue matrix generate and maintain in play a role (Goktiirk, et al.Am.J.Pathol.,
2003,163(5),1921-1928).Moreover, recently it has been found that contacting (Noda, et between SSAO and angiogenesis
Al.FASEBJ., 2008,22 (8), 2928-2935), and based on the contact, it is contemplated that SSAO inhibitor has anti-angiogenic generation
Effect.
Many researchs to the mankind are it has proven convenient that in such as congestive heart failure, diabetes, alzheimer disease and inflammation
Illness in, the raising of SSAO activity in blood plasma (del MarHernandez, et al.Neurosci.Lett., 2005,384
(1-2),183-187).The mechanism of these enzyme activity change behinds is not known.It has been proposed that it is generated by endogenous amine oxidases
Active aldehydes and hydrogen peroxide promote angiocardiopathy, diabetic complication and alzheimer disease development (Jiang, et
al.Neuropathol.Appl.Neurobiol.,2008,34(2),194-204).In addition, the enzymatic activity of SSAO is related to inflammation
The Leukocyte extravasation process at position, wherein SSAO have shown high expression on skin in the blood vessels.Therefore, it has been suggested that the inhibition of SSAO
Agent has therapeutic value (Salter-Cid, et in prevention diabetic complication and inflammatory disease
al.J.Pharmacol.Exp.Ther.,2005,315(2),553-562)。
SSAO is raised in gastric cancer and in the tumor vascular system of human melanoma, hepatoma and H/N tumors
In be accredited (Forster-Horvath C, et al.Melanoma Res., 2004,14,135-140).One report
(Marttila-Ichihara F, et al.J.Immunol., 2010,184,3164-3173) has shown inactivating with enzyme
Melanoma growth is more slow in the mouse of SSAO, and its tumor vessel number and diameter are reduced.The growth of these tumours subtracts
It is also manifested in the reduction that marrow sample inhibits cellular infiltration less.It is encouraging that SSAO defect normal tissue medium vessels or lymph
Formation do not influence.
