Biological Activities
Compounds
Conditions
Picrasma chinensis contains bioactive compounds that effectively treat H2O2-damaged SH-SY5Y cells. These extracts demonstrate a significant neuroprotective effect against H2O2-induced damage on human neuroblastoma SH-SY5Y cells. Furthermore, the plant provides therapeutic benefits for the MPTP-damaged mouse brain by protecting dopaminergic neurons. Its derivatives specifically work to treat 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced Parkinson's disease by restoring tyrosine hydroxylase expression. Ultimately, the medicinal properties of Picrasma chinensis allow it to treat MPTP-induced Parkinson's disease in animal models by improving motor behavioral performance.
Preparations
Picrasma chinensis is prepared as an EtOH extract to facilitate the isolation of its chemical constituents. From the ethanol extract of the plant's stems and leaves, researchers successfully isolated six novel cyclopeptide alkaloid-type burpitides known as picrachinentins A-F. This specific extraction method allowed for the full structural elucidation of these unique 14-membered paracyclophane ring systems. By using an EtOH extract, the study was able to identify these compounds as the first reported CPABs from the Simaroubaceae family. Consequently, this preparation method proved essential for uncovering the neuroprotective properties inherent in the plant's bioactive molecules.
Parts used
Picrasma chinensis serves as a significant source of bioactive compounds for pharmacological research. Scientific studies have successfully isolated various chemical constituents, such as sesquiterpenoids and cyclopeptide alkaloid-type burpitides, directly from the plant. These valuable metabolites are specifically extracted from both the leaves and the stems of the species. The compounds found in these plant parts have demonstrated remarkable neuroprotective effects in both in vitro and in vivo models. Consequently, the chemical diversity present in the stems and leaves of Picrasma chinensis holds great promise for developing treatments for neurodegenerative conditions.
