Ruthenium (Ru) (II) complexes with flavonols show strong antioxidant and anti-inflammatory effects. Compound 12 demonstrated significant anti-cancer activity against lung cancer cells, highlighting potential therapeutic applications.
Area of Science:
- Medicinal Chemistry
- Inorganic Chemistry
- Pharmacology
Background:
- Flavonols possess inherent biological activities.
- Metal complexes can modulate and enhance the bioactivity of organic ligands.
- Ruthenium complexes are explored for pharmaceutical applications due to their diverse activities.
Purpose of the Study:
- To synthesize novel flavonol-ruthenium (II) complexes.
- To evaluate the biological activities, including antioxidant, anti-inflammatory, and anti-cancer properties, of these complexes.
- To investigate the potential of these complexes as therapeutic agents.
Main Methods:
- Synthesis of seven distinct flavonol-Ru (II) complexes.
- Assessment of free radical scavenging abilities and antioxidant activity.
- Evaluation of anti-inflammatory effects using quercetin as a positive control.
- In vitro testing against human non-small-cell lung cancer cells (A549), comparing with 5-fluorouracil (5-FU).
Main Results:
- Compounds 8, 11, and 12 exhibited potent antioxidant activities.
- Compound 12 displayed superior anti-inflammatory activity compared to quercetin.
- Compound 12 showed efficacy comparable to 5-FU against A549 lung cancer cells.
- This study is the first to report the antioxidant and free radical scavenging activities of flavonol-Ru (II) complexes.
Conclusions:
- Flavonol-Ru (II) complexes possess significant biological activities.
- Compound 12 is a promising candidate for further development as an anti-inflammatory and anti-cancer agent.
- The findings support the potential of flavonol-ruthenium complexes in pharmaceutical applications.
