CID 2745687 Chemical Properties,Usage,Production

Description

GPR35 is a G protein-coupled receptor that is activated by kynurenic acid and 2-acyl lysophosphatidic acids (e.g., 2-oleoyl lysophosphatidic acid). It is expressed predominantly on immune cells, the brain, and in the gastrointestinal tract. GPR35 is overexpressed in gastric cancer cells. CID-2745687 is a reversible, competitive antagonist of GPR35, blocking activation by the synthetic agonist pamoic acid with a K_i value of 12.8 nM. It less potently blocks activation of GPR35 by zaprinast (IC₅₀ = 160 nM). It shows ~57-fold selectivity for GPR35 over the related receptor GPR55 (IC₅₀ = 9.08 μM).

Uses

CID 2745687 is used as a GPR35 antagonist, with potential application towards immune or gastrointestinal system regulation.

Definition

ChEBI: 5-[[[(tert-butylamino)-sulfanylidenemethyl]hydrazinylidene]methyl]-1-(2,4-difluorophenyl)-4-pyrazolecarboxylic acid methyl ester is a ring assembly and a member of pyrazoles.

in vitro

previous study indicated that both cid-2745687 and ml-145 could competitively inhibit the effects of cromolyn disodium and zaprinast (two agonists sharing an overlapping binding site) on human gpr35. in contrast, though ml-145 antagonized the effects of pamoate competitively, cid-2745687 showed a noncompetitive fashion. additionally, neither ml-145 nor cid-2745687 was able to antagonize the agonist effects at rodent ortholog of gpr35 [1].

in vivo

to test whether gpr35 contributes to the metabolic effect of zaprinast, the retina from cngb1/ mice was preincubated with a gpr35 antagonist, cid-2745687, followed by an additional zaprinast treatment. results showed that cid-2745687 did not block the effect of zaprinast on glutamate and aspartate. moreover, pamoic acid, the gpr35 agonist, did not change aspartate or glutamate levels [1].
