Synthesis of flavonoids nitrogen mustard derivatives and study on their antitumor activity in vitro

Area of Science:

• Medicinal Chemistry
• Pharmacology
• Oncology

Background:

• Flavonoids are natural compounds with potential anticancer properties.
• Nitrogen mustards are a class of chemotherapy drugs.
• Developing novel anticancer agents with improved efficacy is crucial.

Purpose of the Study:

• To synthesize novel flavonoid nitrogen mustard derivatives.
• To evaluate their in vitro antiproliferative activity against various human cancer cell lines.
• To identify promising candidates for further anticancer drug development.

Main Methods:

• Synthesis of novel flavonoid nitrogen mustard derivatives.
• In vitro antiproliferative assay using MTT method.
• Determination of half-maximal inhibitory concentration (IC50) values.
• Cell cycle analysis and apoptosis assays.
• Mitochondrial membrane potential assessment.

Main Results:

• Most synthesized compounds exhibited significant antiproliferative activity against seven human cancer cell lines.
• Several derivatives showed superior activity compared to the established drug melphalan.
• Compound 8b was particularly effective, with a low IC50 value against HeLa cells.
• Compound 8b induced G2/M phase cell cycle arrest and apoptosis in HeLa cells.
• Loss of mitochondrial membrane potential was identified as a potential mechanism of apoptosis induction.

Conclusions:

• Novel flavonoid nitrogen mustard derivatives possess potent in vitro anticancer properties.
• Compound 8b is a highly promising candidate for further investigation as an anticancer agent.
• The mechanism of action involves cell cycle arrest, apoptosis induction, and disruption of mitochondrial function.
