摘要: Screening with dynamic mass redistribution (DMR) assays in a native cell line HT-29 led to identification of two novel series chemical compounds, 2-(4-methylfuran-2(5H)-ylidene)malononitrile and thieno[3,2-b]thiophene-2-carboxylic acid derivatives, as GPR35 agonists. Of these, 2-(3-cyano-5-(3,4-dichlorophenyl)-4,5-dimethylfuran-2(5H)-ylidene)malononitrile (YE120) 6-bromo-3-methylthieno[3,2-b]thiophene-2-carboxylic (YE210) were found be the most potent agonists an EC50 32.5 ± 1.7 nM 63.7 4.1 nM, respectively. Both exhibited better potency than that zaprinast, known agonist. DMR antagonist assays, knockdown interference RNA, receptor internalization Tango β-arrestin translocation confirmed agonist activity these ligands is specific GPR35. The present study provides starting point for further investigations biology pharmacology.
