    Synthesis of new N,N′-bis [1-aryl-3-(piperidine-1-yl)propylidene] hydrazine dihydrochlorides and evaluation of their cytotoxicity against human hepatoma and breast cancer cells
    (Informa Healthcare, 2014) Kucukoglu, K.; Gul, H. I.; Cetin Atalay, R.; Baratli, Y.; Charles, A. L.; Sukuroglu, M.; Gul, M.; Geny, B.
    N,N0-Bis[1-aryl-3-(piperidine-1-yl)propylidene]hydrazine dihydrochlorides were synthesized by the reaction of 2 mols of 1-aryl-3-(piperidine-1-yl)-1- propanone hydrochlorides with 1 mol of hydrazine hydrate. Aryl part was C 6H5 (P1), 4-CH3C6H4 (P2), 4-CH3OC6H4 (P3), 4-HOC6H 4 (P4), 4-ClC6H4 (P5), 3-CH3OC 6H4 (P6), 4-FC6H4 (P7) and 4-BrC6H4 (P8). Except P1, all compounds were reported for the first time. The chemical structures were confirmed by UV, 1H NMR, 13C NMR and HRMS spectra. P1, P2, P7 and P8 against human hepatoma (Huh7) cells and P1, P2, P4, P5, P6, P7 and P8 against breast cancer (T47D) cells have shown cytotoxicity. P1, P2 and P7 had more potent cytotoxicity against Huh7 cells than the reference compound 5-FU, whereas only P2 was more potent than the 5-FU against T47D cells. Representative compound P7 inhibited the mitochondrial respiration at 144, 264 and 424 mM concentrations dose-dependantly in liver homogenates. The results suggest that P1, P2, P7 and P8 may serve as model compounds for further synthetic studies. © 2014 Informa UK Ltd.

    Synthesis, anticancer activities and molecular modeling studies of novel indole retinoid derivatives
    (Elsevier, 2012) Gurkan-Alp, A. S.; Mumcuoglu, M.; Andac, C. A.; Dayanc, E.; Cetin Atalay, R.; Buyukbingol, E.
    In this study, novel (E)-3-(5-substituted-1H-indol-3-yl)-1-(5,5,8,8- tetramethyl-5,6,7,8-tetrahydronaphthalen-2-yl)prop-2-en-1-one (5(a-e)) derivatives were synthesized and their anticancer effects were determined in vitro. Novel indole retinoid compounds except 5e have anti-proliferative capacity in liver, breast and colon cancer cell lines. This anti-proliferative effect was further analyzed in breast cancer cell line panel by using the most potent compound 5a. It was determined that 5a can inhibit proliferation at very low IC50 concentrations in all of the breast cancer cell lines. Here, we present some evidence on apoptotic termination of cancer cell proliferation which may be primarily driven by the inhibition of RXRα and, to a lesser extent, RXRγ. © 2012 Elsevier Masson SAS.
