Description

D-Cycloserine is a broad-spectrum antibiotic and a potent, selective partial agonist of the NMDA receptor glycine site, making it a critical compound for both pharmaceutical research and therapeutic development. Its unique dual mechanism of action provides significant value in studying neurological pathways and combating resistant bacterial strains. This product is essential for researchers in neuroscience, microbiology, and for manufacturers developing advanced antibiotic and neuropsychiatric drug formulations.

Application

• Pharmaceutical Intermediate: Key starting material or active ingredient in the synthesis of antibiotic and neuroactive pharmaceutical products.
• Neurological Research: Widely used as a research chemical to study N-methyl-D-aspartate (NMDA) receptor function, synaptic plasticity, and cognitive processes.
• Antibiotic Agent: Employed as a second-line treatment for multidrug-resistant tuberculosis (MDR-TB) and other bacterial infections.
• Psychiatric Research: Investigated in preclinical and clinical studies for potential adjunctive therapy in conditions like anxiety, PTSD, and Alzheimer's disease.
• Microbiological Studies: Used in laboratory settings for selective pressure in bacterial culture and resistance studies.
• Biochemical Reagent: Serves as a standard or reference compound in analytical chemistry and quality control laboratories.
