The invention relates to the medical field, particularly, relates to a fluroallylamine derivative and use thereof as an inhibitor of vascular adhesion protein-1 (VAP-1)/semicarbazide-sensitive amine oxidase (SSAO).
Vascular adhesion protein-1 (VAP-1) is a glycoprotein dimmer having a relative molecular weight (Mw) ranging from 170,000 to 180,000, and a multifunctional protein that is widely present in mammal animals. The vascular adhesion protein-1 is an endothelial adhesion molecule and also has an activity of semicarbazide-sensitive amine oxidase (SSAO). The protein is widely distributed in tissues, primarily derived from endothelia cells, plain muscle cells and adipose cells, and it is present in vivo in the following two most common forms: a tissue bonding form and a soluble form. And the form that circulates in human and animal blood plasma is the soluble form, which is a cleavage product of the membrane-bound vascular adhesion protein-1/semicarbazide-sensitive amine oxidase.
It is found that vascular adhesion protein-1/semicarbazide-sensitive amine oxidase is induced to express during the formation of fats (Fontana, E., et. al., Biochem. J., 2001, 356, 769; Moldes, M., et. al., J. Biol. Chem., 1999, 274, 9515); vascular adhesion protein-1/semicarbazide-sensitive amine oxidase also play an important role in leukocyte exudation, adhesion cascade reactions, glycometabolism regulation, vascular injuries, etc.; in inflammatory diseases, tissue injury fibrosis, glycometabolism-related diseases, tumors, strokes and many other clinical diseases, both the expressions and the functions of the vascular adhesion protein-1/semicarbamide-sensitive amine oxidase play important roles; in skins of patients suffering from atopic eczema or psoriasis, positive cells having a high level of vascular adhesion protein-1/semicarbazide-sensitive amine oxidase are found.
Generally, vascular adhesion protein-1/semicarbazide-sensitive amine oxidase is an effective biological target for diabetes, pneumonia, hepatitis, pulmonary fibrosis, liver fibrosis, fatty liver, stroke and other inflammatory or fibrosis-related diseases.
Some small organic molecules are found to have inhibitory activity against vascular adhesion protein-1/semicarbazide-sensitive amine oxidase, for example, hydrazines, phenyl-substituted methylhydrazines, hydrazinol, hydrazine-substituted dihydroindenes, aromatic cycloalkylamine, allylamine, propynylamine, oxazolidone, haloalkylamines, 1,3,4-oxazolidone, oxadiazine, sulfamide, thiazole derivatives, and other organic compounds (Dunkel, P. et. al., Curr. Med. Chem., 2008, 15, 1827; Tetra. Letters, 1977, 36, 3155). Also, it was reported that compounds of the propynylamine family can be used to inhibit vascular adhesion protein-1/semicarbazide-sensitive amine oxidase (O'Connell, K. M., et. al., Biochemistry, 2004, 43, 10965). These compounds, for example semicarbazides, exhibit the inhibiting function depending on the hydrazine functional group to form a covalent imine bond with TPQ cofactors.
Through intensive research, the inventor unexpectedly developed a compound having effective inhibitory activity against vascular adhesion protein-1/semicarbazide-sensitive amine oxidase, which can be used in preventing or treating a disease associated with the overactivity of vascular adhesion protein-1/semicarbazide-sensitive amine oxidase. In particular, the invention provides a fluoroallylamine derivative represented by Formula I, which shows outstanding inhibitory activity against vascular adhesion protein-1/semicarbazide-sensitive amine oxidase, good selectivity over monoamine oxidase and diamine oxidase, and improved metabolic stability in vivo.

After being incubated for a certain period of time, an equivalent volume of cooled acetonitrile (4° C.) was added to terminate the reaction, and LC-MS/MS was used to determine the concentrations of the compound after being incubated in various liver microsomes for different time periods. With the incubation time as the horizontal ordinate and the natural logarithm of the percentages of the remained compound at each time point as the longitudinal coordinate, a diagram was plotted, wherein the slope was the velocity constant (Ke), and the half-life (T1/2) and clearance rate (CLliver) of the compound were calculated according to the following equation to evaluate the staiblity of the compound in the liver microsomes.
T1/2=In(2)/Ke
Liver clearance rate (CLliver)=Ke/protein quantity of microsomes contained in per milter of reaction solution (mg)xprotein quantity of microsomes contained in per gram of liver (mg)×liver weight correspondent to body weight per kilogram (g).

Reagents:
Culture medium: 10%FBS+1% unnecessary amino acid+90%DMEM (high glucose)
Permeation solution (pH 7.4): HBSS (Ca+, Mg+)+10 mM Hepes
Compound reservation solution: an amount of the test compound was weighted and added with a certain amount of DMSO to formulate a 10 mM reservation solution.
Experimental Method:
Cells were inoculated to Transwell cells in a quantity of 6*104/cm2, and at the A side (top side), were added with 200 μL of the culture medium, and at the B side (base side), were added with 1000 μL of the culture medium.

Fluorescein: after 2-hours incubation, 100 μL of the permeation solution were taken from each side of side A and side B, and the fluorescent value at Ex=485nm, Em=530nm were measured by an enzyme marker, and the permeation quantity was calculated (less than 1%).
Sample treatment: after 2-hours incubation, 50 μL of the permeation solution were sucked up from each side of side A and side B, and equivalent volume of cold acetonitrile was added to terminate the reaction, and the concentrations of the compound at the A and B sides were measured by LC-MS/MS. The apparent permeation (Papp) and the Efflux Ratio were calculated according to the following equations:
Papp=(dCr/dt)×Vr/(A×C0)
Efflux Ratio=Papp(BA)/Papp (AB)
wherein, dCr/dt is the integration of the concentration of the compound at the base side realted to time, Vr is the reaction volume at the base side, A is the area of a single layer of cells, being 0.33 cm2, and C0 is the concentration of the compound at the top side.
