Biochem/physiol Actions

Theanine is able to bind to AMPA, kainite, and NMDA glycine receptors in rat cortical neurons but with less affinity than glutamic acid. It has been studied as a glutamate transport inhibitor, preventing glutamate uptake by M5076 ovarian sarcoma-bearing mouse cells and increasing the effect of doxorubicin on tumor growth in M5076 mice.
