Pamoic acid (Embonic acid) is a potent GPR35 agonist that demonstrates neuroprotective and anti-inflammatory properties. Its GPR35 activation may increase the phosphorylation of ERK1/2, which helps to suppress NF-κB-dependent inflammatory genes.
- Potent GPR35 agonist with an EC50 of 79 nM.
- Shows agonist activity at human GPR35 in CHO cell lines.
- Demonstrates neuroprotective activity in a mouse stroke model.
- Reduces infarct size in a GPR35-dependent manner.
- Increases noninflammatory Ly-6CLo monocytes/macrophages in the ischemic brain.
- Reduces neutrophil counts.
