Embodiment 1

[0025] .

[0026] A. Compound IV-1 Synthesis

[0027] 3.46g (20mmol) compound II-1 and 2.64g (20mmol) of compound III Dissolve in 50mL of dry THF, stir under ice-water bath cooling, add 4.13g (20mmol) of dicyclohexylcarbodiimide (DCC) and 0.61g (5mmol) of 4-dimethylaminopyridine (DMAP), and then stir at room temperature , until the TLC detection reaction was complete (within 12h). The reaction mixture was poured into 300 mL of ice water, stirred, using 100 mL × 3 CH 2 Cl 2 Extract, combine the extract phases, successively wash with 100mL of 1% dilute hydrochloric acid and 100mL of 5% brine, and dry over anhydrous sodium sulfate. The desiccant was removed by suction filtration, the filtrate was evaporated to dryness on a rotary evaporator, and the obtained residue was purified by column chromatography to obtain compound IV-1 , white solid, ESI-MS, m / z =310([M+Na] + ).

Embodiment 10

[0038] The compounds of the present invention and related compounds inhibit IC of URAT1 50 The values ​​are determined in a similar manner as described in the literature (Example 12 in US2014 / 0005136). The results are listed below.

[0039] Construction of a cell line stably expressing the humanized URAT1 transporter: The humanized URAT1 gene (SLC22A112) was subcloned from the plasmid pCMV6-XL-5 (Origene) into the eukaryotic expression plasmid pCMV6 / neo (Origene). Gene sequencing confirmed that the humanized URAT1 was consistent with the information recorded in the gene bank (NM_144585.2). HEK293 human embryonic kidney cells (ATCC#CRL-1573) were cultured in EMEM tissue culture medium under 5% CO 2 and 95% air atmosphere. pCMV6 / Neo / URAT1 was transfected onto HEK293 cells using L2000 type transfection reagent (Invitrogene). After 24 hours, the transfected cells were divided into tissue culture dishes with a diameter of 10 cm, continued to grow for one day, and then the mediu...

Abstract

The invention relates to the field of drugs related to hyperuricemia and gout, particularly to urate transporter 1 inhibitors adopting succinimide structures containing methoxyl naphthalene rings, preparation methods of the urate transporter 1 inhibitors, drug composition containing the urate transporter 1 inhibitors and applications of the urate transporter 1 inhibitors to preparation of diabetes drugs. The structural formula is shown in the specification, wherein R<1> is selected from H and halogen substituents.

Description

technical field [0001] The invention relates to the field of drugs related to the treatment of hyperuricemia and gout. In particular, the present invention relates to a class of uric acid transporter 1 (uratetransporter1, URAT1) inhibitors containing succinic acid amide derivatives containing a naphthalene ring, which have a therapeutic effect on hyperuricemia and gout, a preparation method, and a method containing them. The pharmaceutical composition and its use in medicine. Background technique [0002] Gout is a chronic metabolic disease characterized by hyperuricemia and pain caused by deposition of monosodium uric acid (MSU) in joints and other parts. The main reason is purine metabolism disorder and / or uric acid excretion disorder. It is estimated that there are more than 20 million gout patients worldwide. Drugs currently used to treat gout include anti-inflammatory drugs for pain relief (such as colchicine, etc.), drugs that inhibit uric acid production (xanthine o...
