CID 2745687 is a competitive, reversible antagonist of the orphan receptor GPR35. It blocks the GPR35-mediated increase in ERK1/2 phosphorylation and beta-arrestin recruitment induced by pamoic acid (sc-212523). It less potently blocks activation of GPR35 by zaprinast (IC50 = 160 nM) and shows about 57-fold selectivity for GPR35 over the related receptor GPR55 (IC50 = 9.08 µM). CID 2745687 is expressed predominantly in immune cells and in the gastrointestinal tract. In addition, it is overexpressed in gastric cancer cells.
