In Vitro |
For ERK1/2 phosphorylation with 1 μM Pamoic acid as the agonist, the CID 2745687 (CID2745687) Ki is 18 nM[1]. CID 2745687 (CID-2745687) is a potent antagonist in β-arrestin-2 interaction assays only at human GPR35[2]. Using the BRET-based GPR35-β-arrestin-2 interaction assay and an EC80 concentration of Zaprinast (20 μM) as agonist, CID 2745687 behaved as a moderately potent, concentration-dependent antagonist at human GPR35 with pIC50=6.70±0.09[2]. CID 2745687 (pIC50=6.27±0.08) fully reverses the agonist action of Cromolyn disodium [2].

In Vivo |
CID 2745687 (CID2745687; 1 mg/kg; administrated orally every day for the last 4 weeks), a specific GPR35 antagonist, reverses Lodoxamide-mediated anti-fibrotic effects[3]. Animal Model: Six-week-old male C57BL/6 mice[3] Dosage: 1 mg/kg Administration: Oral administration, every day for 4 weeks Result: Inhibited Lodoxamide-mediated protective effects.
