Abstract A new canthin-5,6-dione and β-carboline dimericalkaloid, picrasidine-U was isolated from the root wood of Picrasmaquassioides. The structure was determined by spectral analysis and chemical evidence.
cerebral protective effect. Among these, compound 2 exhibited a cerebral protective effect through suppressing neuronal hyperexcitability due to an increase in the excitatory neurotransmitter glutamic acid. Furthermore, compound 2 did not affect heart rate and mean systolic blood pressure. This investigation suggests that compound 2 has potential for further development as a cerebral protective drug.
