Synthesis of some novel pyrano[2,3-f]chromenone derivatives

Synthesis and Anticancer Activity of Some 1H-inden-1-one Substituted (Heteroaryl)Acetamide Derivatives

Background:

The synthesis of 2-[3/4-((6-substituted-1-oxo-2,3-dihydro-1H-inden-2- ylidene)methyl)phenoxy]-N-(heteroaryl)acetamide derivatives and the investigation of their anticancer activity were studied.

Methods:

2-(3/4-Hydroxybenzylidene)-6-substituted-2,3-dihydro-1H-inden-1-ones were reacted with suitable 2-chloroacetamides to give 2-[3/4-((6-substituted-1-oxo-2,3-dihydro-1H-inden-2-ylidene) methyl)phenoxy]-N-(heteroaryl)acetamide derivatives.

Results:

The structure elucidation of the newly synthesised 16 compounds was performed by IR, 1H-NMR, mass spectroscopic data and elemental analyses. The anticancer screening was carried out in National Cancer Institute (NCI), USA.

Conclusion:

Compound 3e (2-(3-((6-chloro-1-oxo-2,3-dihydro-1H-inden-2-ylidene)methyl)phenoxy)- N-(thiazol-2-yl)acetamide), exhibited highest growth inhibition against the leukaemia (61.47%), non-small cell lung cancer (79.31%) and breast cancer (62.82%) cell lines.

New chroman-4-one/thiochroman-4-one derivatives as potential anticancer agents

The synthesis of 3-[3/4-(2-aryl-2-oxoethoxy)arylidene]chroman/thiochroman-4-one derivatives (1-34) and evaluation of their anticancer activities were aimed in this work. Final compounds were obtained in multistep synthesis reactions using phenol/thiophenol derivatives as starting materials. For anticancer activity evaluation, all compounds were offered to National Cancer Institute (NCI), USA and selected ones were tested against sixty human tumor cell lines derived from nine neoplastic diseases. The activity results were evaluated according to the drug screening protocol of the institute. Compounds containing thiochromanone skeleton exhibited higher anticancer activity.
