New Chalcone Ester Derivatives as Potential Cytotoxic Agents

Area of Science:

• Medicinal Chemistry
• Organic Synthesis
• Cancer Research

Background:

• Chalcones possess significant biological potential, especially in anticancer applications.
• Optimizing chalcone structures is a key strategy for enhancing their therapeutic efficacy.
• Esterification is a viable synthetic route for developing novel chalcone derivatives.

Purpose of the Study:

• To synthesize novel chalcone derivatives via esterification.
• To evaluate the cytotoxic potential of these derivatives against various cancer cell lines.
• To identify lead compounds with enhanced anticancer activity and selectivity.

Main Methods:

• Synthesis of eight chalcone derivatives (1a-b, 2a-f) from 3'-hydroxychalcone (1) using esterification.
• Structural characterization using Nuclear Magnetic Resonance (NMR) and Fourier-Transform Infrared (FT-IR) spectroscopy.
• Cytotoxicity assays on HCT 116 (colon cancer), MCF-7 (breast cancer), and CCD-18Co (normal colon fibroblast) cell lines.

Main Results:

• Chalcone derivatives exhibited greater activity against the colon cancer cell line (HCT 116).
• Compounds 1a and 2b showed IC50 values around 10 μM in HCT 116 cells, with moderate selectivity over MCF-7 and CCD-18Co cells.
• Compounds 1a and 2d were identified as having the best cytotoxic results among the synthesized esterified chalcones.

Conclusions:

• Esterification of chalcones yields derivatives with notable cytotoxic potential against cancer cells.
• Compounds 1a and 2d represent promising candidates for further investigation in colon cancer therapy.
• The tested derivatives did not show synergistic effects when combined with doxorubicin.
