What is Pamoic acid?

Chemical properties

Pamoic acid is yellow to yellow-green crystalline powder

The Uses of Pamoic acid

Pamoic acid is used in preparation of repository derivatives of medicinal agents, used in pharmacology to increase the solubility of a drug in water.

The Uses of Pamoic acid

Pamoic acid is a potent GPR35 agonist that has been found to exhibit antimicrobial activity against a variety of microorganisms. Pamoic acid is also used in the treatment of infectious diseases, such as leprosy, tuberculosis, and AIDS.

Definition

ChEBI: Pamoic acid is a dicarboxylic acid. It is functionally related to a 2-naphthoic acid. It is a conjugate acid of a pamoate(2-).

General Description

Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards.

Safety Profile

Poison by intraperitoneal route. An eye irritant. When heated to decomposition it emits acrid smoke and irritating fumes.

Mechanism of action

Pamoic acid is able to inhibit the synthesis of peptide hormones by binding to their receptors on the cell surface. This inhibition can lead to immunosuppression (e.g., autoimmune diseases) and mitochondrial membrane depolarization.

Preparation

Pamoic acid can be prepared by the reaction of 3-hydroxy-2-naphthoic acid with formaldehyde.
