Isolation, Synthesis And Structure Determination Of Cannabidiol Derivatives And Their Cytotoxic Activities.

Area of Science:

• Natural Product Chemistry
• Medicinal Chemistry
• Pharmacology

Background:

• Exploring structural diversity and pharmacological activities of natural products is crucial.
• Cannabidiol (CBD) is a prominent natural product with therapeutic potential.

Purpose of the Study:

• To isolate, synthesize, and determine the structure of cannabidiol derivatives.
• To evaluate the cytotoxic activities of these compounds against various cancer cell lines.

Main Methods:

• Isolation and synthesis of cannabidiol derivatives.
• Structure elucidation using spectroscopic analyses (NMR, ECD) and DFT calculations.
• In vitro cytotoxic evaluation against eight cancer cell lines.

Main Results:

• A new cannabidiol derivative (6) was synthesized along with six known compounds (2-5, 7, 8).
• Compounds 4, 5, 7, and 8 exhibited notable in vitro cytotoxic activity (IC50: 5.6-60 μM).
• Compounds 4 and 7 demonstrated cytotoxic activity comparable to cannabidiol (1) against most tested cancer cell lines.

Conclusions:

• The study successfully generated and characterized novel cannabidiol derivatives.
• Several derivatives possess significant cytotoxic potential, warranting further investigation for anticancer drug development.
