    Evaluation of in Vivo Biological Activity Profiles of Isoindole-1,3 Derivatives: Cytotoxicity, Toxicology, and Histopathology Studies
    (Amer Chemical Soc, 2023) Köse, Aytekin; Kaya, Meltem; Tomruk, Canberk; Uyanıkgil, Yiğit; Kıshalı, Nurhan; Kara, Yunus; Şanlı Mohamed, Gülşah
    The anticancer activity of N-benzylisoindole-1,3-dione derivatives was evaluated against adenocarcinoma (A549 Luc). First, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide activity assay studies of two isoindole-1,3-dione derivatives were performed against A549 cell lines. Both compounds showed inhibitory effects on the viability of A549 cells. Then, we explored the potential of these compounds as active ingredients by in vivo studies. Nude mice were given A549-luc lung cancer cells, and tumor growth was induced with a xenograft model. Then, nude mice were divided into three groups: the control group, compound 3 group, and compound 4 group. After application of each compound to the mice, tumor sizes, their survival, and weight were determined for 60 days. Furthermore, toxicological studies were performed to examine the effects of the drugs in mice. In addition to toxicological studies, histopathological analyses of organs taken from mice were performed, and the results were evaluated. The obtained results showed that both N-benzylisoindole derivatives are potential anticancer agents.

    Regio- and Stereo-Chemical Ring-Opening Reactions of the 2,3-Epoxy Alcohol Derivative With Nucleophiles: Explanation of the Structures and C-2 Selectivity Supported by Theoretical Computations
    (Elsevier, 2022) Gündoğdu, Özlem; Atalay, Abdurrahman; Çelebioğlu, Neslihan; Anıl, Barış; Şahin, Ertan; Şanlı Mohamed, Gülşah; Bozkaya, Uğur; Kara, Yunus
    The ring-opening reactions of (1aS,2S,6bR)-5-ethyl-2-hydroxyhexahydro-4H-oxireno[2,3-e]isoindole-4,6(5H)-dione were investigated under very mild and nonchelated conditions. C-2 selective ring-opening products were obtained with nucleophilic additions such as Cl−, Br− and N3−. The exact configuration of (3aS,4R,5R,6S,7aS)-5-chloro-2-ethyl-4,6-dihydroxyhexahydro-1H-isoindole-1,3(2H)-dione was determined by X-Ray diffraction analysis which was obtained from the reaction of epoxy alcohol with HCl. On the other hand, theoretical computations were carried out to explain the regioselectivity in the ring opening reaction of epoxy alcohols. The results showed that the ring-opening reaction of both epoxy alcohols proceeds in a kinetically controlled manner and regioselectivity occurs depending on the transition state.
