[0064] The preparation of embodiment 1 compound HYH1
[0065]
[0066] Step a: o-hydroxyacetophenone (compound 1, 10g, 73.5mmol, 1eq) was dissolved in N,N-dimethylformamide dimethyl acetal (DMF-DMA) 15ml, 113.9mmol, 1.55eq), The mixture was reacted at 100°C for 2 hours, and the reaction was completed. Cooling, precipitated solid, filtered, and washed with 30ml ethyl acetate to obtain intermediate product (E)-3-(dimethylamino)-1-(2-hydroxyphenyl)-propenone (compound 2), 1 H NMR (300MHz, CDCl 3 )δ9.20(s, 1H), 8.08(s, 1H), 7.51(m, 2H), 7.03(s, 1H), 4.60(s, 1H), 2.91(s, 6H).
[0067] Step b: (E)-3-(dimethylamino)-1-(2-hydroxyphenyl)-propenone (13g, 68mmol, 1eq) and elemental iodine (34.5g, 136mmol, 2eq) and pyridine (5.5ml , 68mmol, 1eq) was dissolved in 150ml chloroform and reacted for 6 hours, and the reaction was completed. Cool, add 150ml sodium sulfite saturated solution to remove excess iodine, extract three times with 150ml ethyl acetate respectively, combine organic...

Description
technical field [0001] The invention belongs to the field of pharmacy, and in particular relates to a new type of xanonechromone compound or a pharmaceutically acceptable salt thereof, a pharmaceutical composition containing the compound, a preparation method and an application thereof. Background technique [0002] The bile acid receptor TGR5 (Takeda G-protein coupled Receptor5) is one of the hot targets reported in recent years for the treatment of diabetes. It belongs to the G protein-coupled receptor family (GPCRs) rhodopsin-like protein family. Also known as M-BAR, GPR131, BG37, etc., it is a lipid receptor expressed on the cell membrane [Maruyama, T. etal. Biochem. Biophys. Res. Commun. 2002, 298 (5), 714-719.; Kawamata, Y.etal.J.Biol.Chem.2003,278(11),9435-9440], widely distributed in the body. The expression level of TGR5 in different tissues is different, and the expression level is higher in the gallbladder, followed by the placenta, spleen, and intestine; the exp...
