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

WOS: 000414346300017PubMed ID: 29158716The 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.Anadolu University, Turkey (BAP) [050301]This work was supported by Anadolu University, Turkey (BAP Project No: 050301).

Synthesis and antifungal activities of some aryl naphthofuran ketoximes

In this study, some aryl naphtho[2, 1-b]furan-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 tested against Candida albicans (two strains), Candida glabrata, Candida tropicalis and Candida parapsilosis using a microbroth dilution technique. The results showed that the compounds displayed minimum inhibitory concentrations, 7.8-625 µg/mL

Synthesis and antiproliferative activity of 2-arylidene 6-(2-aryl-2-oxoethoxy) benzofuran-3-one derivatives

WOS: 000389460600011The synthesis of 2-arylidene 6-(2-aryl-2-oxoethoxy) benzofuran-3-one derivatives was reported and selected compounds were determined for their anticancer activity evaluation in National Cancer Institute NCI, USA according to the drug screening protocol of the institute against approximately 60 tumor cell lines derived from nine cancer diseases. Compound 3r, namely 2-(4-chlorobenzylidene)- 6-[2-(4-methoxyphenyl)-2-oxoethoxy] benzofuran-3-one exhibited the highest antitumor activity against non-small lung cancer cell lines.Anadolu University, Turkey (BAP Project) [050301]The study was financially supported by Anadolu University, Turkey (BAP Project No: 050301).

Synthesis and anticancer activity of some 2-[3/4-(2-substituted phenyl-2-oxoethoxy)benzylidene]-6-substituted-2,3-dihydro-1H-inden-1-one derivatives

WOS: 000335394500005The synthesis of 2-[3/ 4-(2-substituted phenyl-2-oxoethoxy) benzylidene]-6-substituted-2,3-dihydro-1H-inden-1one derivatives and the investigation of their anticancer activity were studied. 2-(3- or 4-Hydroxybenzylidene)-6substituted- 2,3-dihydro-1H-inden-1-ones were reacted with suitable 2-bromoacetophenones to give 2-[3/ 4-(2-substituted phenyl-2-oxoethoxy) benzylidene]-6-substituted-2,3-dihydro-1H-inden-1-one derivatives. The structure elucidation of the synthesised 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. Notable activity was obtained for some compounds.Anadolu University, Turkey [050301]This work was supported by Anadolu University, Turkey (BAP Project No: 050301).

Synthesis and anti-cancer activity evaluation of new aurone derivatives

WOS: 000361328700014PubMed ID: 25716125In 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 a-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.Anadolu University, Turkey (BAP) [050301]This work was supported by Anadolu University, Turkey (BAP Project No: 050301).
