D-Isoleucine

Synonyms: (R)-Isoleucine

D-Isoleucine is a selective competitive activator of the Asc-1 antiporter, exhibiting a Ki value of 0.98 mM. By binding to the Asc-1 protein on neuronal cell membranes, D-Isoleucine facilitates the release of D-serine and glycine, thereby enhancing NMDA receptor-dependent synaptic plasticity. This compound is relevant in the study of neurodegenerative diseases, including Alzheimer's disease and schizophrenia. Additionally, D-Isoleucine serves as a non-classical D-amino acid, disrupting bacterial peptidoglycan synthesis and inhibiting biofilm formation in Staphylococcus aureus, suggesting its potential utility in antibacterial research.
