Discovery of 2-(4-Methylfuran-2(5H)-ylidene)malononitrile and Thieno[3,2-b]thiophene-2-carboxylic Acid Derivatives as G Protein-Coupled Receptor 35 (GPR35) Agonists
摘要:
Screening with dynamic mass redistribution (DMR) assays in a native cell line HT-29 led to identification of two novel series of 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) and 6-bromo-3-methylthieno[3,2-b]thiophene-2-carboxylic acid (YE210) were found to be the two most potent GPR35 agonists with an EC50 of 32.5 +/- 1.7 nM and 63.7 +/- 4.1 nM, respectively. Both agonists exhibited better potency than that of zaprinast, a known GPR35 agonist. DMR antagonist assays, knockdown of GPR35 with interference RNA, receptor internalization assays, and Tango beta-arrestin translocation assays confirmed that the agonist activity of these ligands is specific to GPR35. The present study provides novel chemical series as a starting point for further investigations of GPR35 biology and pharmacology.
The invention relates to novel polymers containing one or more units derived from fused bis(thienothiophene) moieties, methods for their preparation and monomers used therein, blends, mixtures and formulations containing them, the use of the polymers, blends, mixtures and formulations as semiconductor in organic electronic (OE) devices, especially in organic photovoltaic (OPV) devices, and to OE and OPV devices comprising these polymers, blends, mixtures or formulations.
