[0130] A THF (2 mL) solution of compound I-0 (3-bromobenzenesulfonyl chloride) (610 mg, 2.39 mmol) was added dropwise into aqueous ammonia (6 mL), and reacted at room temperature for 5 h. The reaction solution was extracted with EtOAc (20mL), and the organic phase was washed with water (10mL) and saturated brine (10mL) successively, and anhydrous Na 2 SO 4 After drying, filtering, and evaporating the solvent under reduced pressure, the compound I-1 (534 mg, 95%) was obtained as a white solid.
[0131] Compound I-1 (238mg, 1.01mmol), p-methoxycarbonylphenylboronic acid (200mg, 1.11mmol), anhydrous K 2 CO 3 (279mg, 2.02mmol), Pd(PPh 3 ) 4 (58 mg, 0.05 mmol) was added to Toluene (Tol) (10 mL) and MeOH (2 mL), and reacted for 3 h under nitrogenatmosphere at 80°C. Cool at room temperature, filter and wash the filter cake with EtOAc...

Abstract
The invention discloses an amide compound and medical application thereof as an STING inhibitor, and particularly relates to a compound shown as a formula I or a formula II or pharmaceutically acceptable salt or ester or solvate thereof, which can be used for preparing the STING inhibitor or medicine for inhibiting STING signal path activation and preparing medicine for preventing or treating STING mediated diseases.
Description
technical field [0001] The invention belongs to the field of biomedicine, in particular to a class of novel amide compounds or pharmaceutically acceptable salts or solvates thereof, which can act on transmembrane protein 173 (TMEM173), also known as STING (stimulator of interferongene ), as well as preparation and medical use thereof, the present invention also relates to the use of such compounds in the preparation of medicines for preventing or treating STING-mediated diseases. Background technique [0002] The activation of the body's innate immune system is mediated by the recognition of non-self pathogen-associated molecular patterns (pathogen-associated molecular patterns, PAMPs) by pattern recognition receptors (PRRs) expressed on the cell membrane and in the cytoplasm. After recognizing PAMPs, PRRs activate the conduction of downstream immune signals, promote the release of inflammation and immune cytokines, and further activate the body's adaptive immune system to ...
