Embodiment 1

[0022] The synthesis of embodiment 1 compound I-1

[0023]

[0024] Step 1. Synthesis of compound IV-1

[0025] Compound II-1 (2.36g, 10mmol), Compound III (2.06g, 10mmol), Pd(OAc) 2 (0.22g, 1mmol), BINAP (2,2'-bisdiphenylphosphino-1,1'-binaphthyl, 0.62g, 1mmol) and t-BuOK (2.24g, 20mmol) were added to 50mL dry 1 , 2-dimethoxyethane (DME), the reaction mixture was stirred overnight under nitrogen atmosphere, TLC detection found that the reaction was complete.

[0026] The reaction mixture was carefully poured into 200mL ice water, stirred, and washed with 50mL×3CH 2 Cl 2 After extraction, the extract phases were combined, washed successively with 1% dilute hydrochloric acid and brine, and dried over anhydrous sodium sulfate. The desiccant was removed by suction filtration, the filtrate was evaporated to dryness on a rotary evaporator, and the residue was purified by silica gel column chromatography to obtain compound IV-I, 2.71 g (yield 75%). ESI-MS, m / z=362 ([M+H] +...

Embodiment 3

[0038] Example 3 Analysis of compounds inhibiting SSAO in vitro

[0039] All preliminary assays were performed at room temperature using purified recombinantly expressed human SSAO. Enzymes were prepared essentially as described in Ohman et al. (Protein Expression and Purification, 2006, 46, 321-331). In addition, secondary and selectivity assays were performed using SSAO prepared from various tissues or purified rat recombinant SSAO. Enzyme activity was determined by using hydrogen peroxide generation in a horseradish peroxidase (HRP) coupled reaction using benzylamine as a substrate. Briefly, test compounds were dissolved in dimethyl sulfoxide (DMSO) to a concentration of 10 mM. Dose-response measurements were determined by serial dilutions of 1:10 in DMSO to generate 7-point curves or by serial dilutions of 1:3 in DMSO to generate 11-point curves. The highest concentration was adjusted according to the potency of the compound and then diluted in reaction buffer to give...

Abstract

The present invention relates to the field of SSAO inhibitors. Specifically, the present invention relates to a triazole compound containing morpholine and piperazine, which can be used as an SSAO inhibitor, its preparation method and its application in the preparation and treatment of inflammatory diseases, immune diseases and tumors.

Description

technical field [0001] The present invention relates to the field of SSAO inhibitors. Specifically, the present invention relates to a triazole compound containing morpholine and piperazine which has a therapeutic effect on inhibiting SSAO, which can be used as an SSAO inhibitor, its preparation method, and its use in pharmacy Background technique [0002] Semicarbazide-sensitive amine oxidase (SSAO) activity is produced by vascular adhesion protein-1 (Vascular Adhesinon Protein-1, VAP-1) or copper-containing amine oxidase (AmoneOxidase, Copper Containing 3, AOC3 ), which belongs to the family of copper-containing amine oxidases (EC.1.4.3.6). Therefore, inhibitors of SSAO enzymes can also regulate the biological functions of VAP-1 protein. Members of this enzyme family are sensitive to inhibition by semicarbazides and use copper ions and the protein-derived hydroxydopaquinine (TPQ) cofactor for the oxidation of primary amines to aldehydes, hydrogen peroxide, and ammonia D...
