ConclusionsĬurcuminoids with diferuloyl(4-hydroxy-3-methoxycinnamoyl) moiety with mono carbonyl exhibiting potential cytotoxic properties. Structure–activity relationships revealed that the mono-carbonyl with 2,5-dimethoxy substituted curcuminoids could be an essential for the future drugs against cancer diseases. Additionally, we are going to report the first time spectral data of (2 E,6 E)-2,6-bis(2-methoxybenzylidene)cyclohexanone ( 1). The structure of compound 4 was confirmed by using the single X-ray crystallography. All the curcucminoids were characterized with the detailed 1H NMR, IR, UV–Vis, and mass spectroscopic techniques. Among the cyclohexanone series, the compound 4 exhibited (IC 50 = 11.04 ± 2.80, 6.50 ± 01.80, 8.70 ± 3.10 and 2.30 ± 1.60 µg/mL) potential cytotoxicity against four proposed cancer cell lines, respectively.

Among them, acetone series 11– 17 were found to be more selective and potential cytotoxic agents. These curcuminoids 1– 24 were screened against HeLa, K562, MCF-7 (an estrogen-dependent) and MDA-MB-231 (an estrogen-independent) cancer cell lines. All the curcuminoids were synthesized by the acid or base catalyzed Claisen Schmidt condenstion reactions, in which β-diketone moiety of curcumin was modified with mono-ketone. Twenty-four curcumin derivatives have synthesized, which comprises cyclohexanone 1– 10, acetone 11– 17 and cyclopentanone 18– 24 series. However, in vivo administration exhibited limited applications in cancer therapies.
