Description
Curator's Comment: description was created based on several sources, including: https://clinicaltrials.gov/ct2/show/NCT00003241?term=Phenylacetic+acid&rank=3 https://en.wikipedia.org/wiki/Phenylacetic_acid

Phenylacetic acid (abr. PAA and synonyms are: α-toluic acid, benzeneacetic acid, alpha tolylic acid, 2-phenylacetic acid, β-phenylacetic acid) is an organic compound containing a phenyl functional group and acarboxylic acid functional group. Because it is used in the illicit production of phenylacetone (used in the manufacture of substituted amphetamines), it is subject to controls in countries including the United States and China Phenylacetic acid is used in some perfumes, possessing a honey-like odor in low concentrations, and is also used in penicillin G production. It is also employed to treat type II hyperammonemia to help reduce the amounts of ammonia in a patient's bloodstream by forming phenylacetyl-CoA, which then reacts with nitrogen-rich glutamine to form phenylacetylglutamine. This compound is then secreted by the patient's body. In Phase 2 of clinical research it investigated in the treatment of Brain and Central Nervous System Tumors.

CNS Activity

Curator's Comment: Known to be CNS penetrant in cat. Human data not available. Labeled phenylacetic acid (14C-PAA) penetrates blood-cerebrospinal fluid (CSF) barrier in cats only under a high gradient of concentration
