Synthesis and antifungal activities of some aryl(benzofuran-2-yl)ketoximes

In this study, some aryl(benzofuran-2-yl)ketoximes and their ethers and esters were synthesised. The structure elucidation of the compounds was performed by IR, 1H NMR and mass spectroscopic data and elemental analyses results. Antifungal activities of the compounds were examined and notable activity was obtained.

Synthesis and anti-cancer activity evaluation of new aurone derivatives.

Abstract In this study, we have synthesized 2-[3- or 4-(2-aryl-2-oxoethoxy)arylidene]benzofuran-3-one derivatives (D1–D38) and evaluated their anti-cancer activities. The final compounds were obtained in multistep synthesis reactions using benzofuranon-3-one derivatives (A1–A4, B) as starting materials which were gained in various synthetic ways. Aurone derivatives (C1–C10) were acquired with the condensation reaction of these starting materials and 3-/4-hydroxybenzaldehyde which were then reacted with α-bromoacetophenones to get final compounds. The anti-cancer activity of the selected compounds was performed by National Cancer Institute (NCI), USA against 60 human tumor cell lines derived from nine neoplastic diseases. Compounds exhibited anti-cancer activity in varying ratios.

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.
