KAT II is responsible for as much as 75% of KYNA synthesis in most brain areas [61,199] and its downregulation has been related to numerous brain diseases involving KYNA depletion [200]

A greater understanding of the regulation of the enzyme under physiological conditions and in the presence of DCA will lead to safer and more effective use of the drug in the future

Future studies can address this issue through liquid chromatography/mass spectrometry (LC/MS) technique, both for the analysis of the active compounds of SJZD, and for the study of metabolomics and pharmacokinetic

This blends stability, molecular precision, and complementary biochemical activity make it a uniquely powerful tool for research targeting integrated tissue healing, immune modulation, and regenerative signaling networks.
