Two new alkaloids from artabotrys uncinatus

Area of Science:

• Natural Product Chemistry
• Phytochemistry
• Organic Chemistry

Background:

• Artabotrys uncinatus is a plant species known for its potential medicinal properties.
• Aporphine alkaloids are a class of natural products with diverse biological activities.
• Previous research has identified various compounds from the Artabotrys genus.

Purpose of the Study:

• To isolate and characterize novel compounds from the fresh unripe fruits of Artabotrys uncinatus.
• To elucidate the chemical structures of the newly discovered compounds.
• To contribute to the understanding of the phytochemical profile of Artabotrys uncinatus.

Main Methods:

• Extraction and isolation of compounds from plant material.
• Structure elucidation using spectroscopic techniques including UV, IR, NMR, and MS.
• Comparison with known compounds for identification.

Main Results:

• Isolation and characterization of a novel oxazoloaporphine, artabonatine A (1).
• Isolation and characterization of a new 7-hydroxyaporphine, artabonatine B (2).
• Identification of five known compounds from the same plant source.

Conclusions:

• Artabotrys uncinatus fruits are a source of novel aporphine alkaloids.
• The identified compounds, artabonatine A and B, represent new chemical entities.
• The structural characterization provides valuable data for further pharmacological investigations.
