5,7-Dichlorokynurenic acid

5,7-Dichlorokynurenic acid (5,7-DCKA) is a synthetic compound that acts as an antagonist at the glycine site of the N-methyl-D-aspartate receptor (NMDAR). It is used in scientific research to study the function of the NMDAR and its role in various neurological and psychiatric disorders.

Chemistry

5,7-DCKA is a derivative of kynurenic acid, a naturally occurring compound in the brain. The addition of two chlorine atoms at positions 5 and 7 on the kynurenic acid molecule enhances its antagonistic activity at the NMDAR.

Pharmacology

5,7-DCKA acts by binding to the glycine site of the NMDAR, thereby inhibiting the receptor's function. The NMDAR is a type of ionotropic glutamate receptor that plays a key role in synaptic plasticity, learning, and memory. Dysregulation of NMDAR function has been implicated in a variety of neurological and psychiatric disorders, including schizophrenia, depression, and Alzheimer's disease.

Research uses

5,7-DCKA is used in preclinical research to study the role of the NMDAR in various physiological and pathological processes. For example, it has been used to investigate the role of the NMDAR in neurotoxicity and neuroprotection, the mechanisms of synaptic plasticity, and the pathophysiology of various neurological and psychiatric disorders.

Safety

As a research chemical, 5,7-DCKA is not intended for human consumption. Its safety profile in humans is unknown.
