pale yellow to yellow powder | [Uses]
Pamoic acid disodium salt, a supposedly inactive component in many formulations of drugs used to modulate release, is a potent agonist of the orphan receptor GPR35. GPR35 is a class A, rhodopsin-like G protein-coupled receptor (GPCR), strongly expressed in the lower intestine and colon, dorsal root ganglia, as well as a variety of immune cells including monocytes and dendritic cells. Targeting GPR35 provides potential therapeutic opportunities in a range of conditions, such as inflammation, pain and cancer. | [Flammability and Explosibility]
Notclassified | [Biological Activity]
Pamoic acid disodium salt is a GPR35 agonist. Induces GPR35 internalization and activates ERK1/2 (EC50 values are 22 and 65 nM respectively). Mediates recruitment of β-arrestin2 to GPR35. Also exhibits antinociceptive effects in a mouse model of visceral pain. | [in vivo]
Pamoic acid disodium (0-100 mg/kg; s.c.; once) induces a dose-related antinociception in the abdominal constriction test[1]. | Animal Model: | Swiss-Webster mice (30–35 g)[1] | | Dosage: | 25, 50, and 100 mg/kg | | Administration: | Subcutaneous injection, once | | Result: | Elicited dose-related antinociception, the dose causing 50% antinociception being 40.5 mg/kg. |
