PG - 550-4 LID - 10.1021/ml300076u [doi] AB - 5,6-Dihydroxyindole-2-carboxylic acid (DHICA), an intermediate of melanin synthesis and an eumelanin building block, was recently discovered to be a GPR35 agonist with moderate potency. Here, we report the synthesis and pharmacological characterization of a series of DHICA analogues against GPR35 using both label-free dynamic mass redistribution and Tango beta-arrestin translocation assays. This led to identification of novel GPR35 agonists with improved potency and/or having biased agonism.
