- To identify specific chalcone compounds with high efficacy against cancer cells and tumors.
Main Methods:
- Synthesis of various chalcone derivatives.
- In vitro evaluation of antimitotic activity using HeLa cells at a concentration of 4 nM.
- In vivo assessment of antitumor activity in experimental models, including L1210 leukemia and B16 melanoma.
Main Results:
- Compound 73, (E)-1-(2,5-dimethoxyphenyl)-3-[4-(dimethylamino)phenyl]-2-methyl-2-propen-1-one, exhibited potent antimitotic effects at 4 nM in vitro.
- This compound demonstrated significant antitumor activity against L1210 leukemia and B16 melanoma in vivo.
Conclusions:
- Chalcone derivative 73 is a highly effective antimitotic agent with promising in vivo antitumor activity.
