Evaluation of In Vivo Biological Activity Profiles of Isoindole-1,3-dione Derivatives: Cytotoxicity, Toxicology, and Histopathology Studies.

The anticancer activity of -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.

Evaluation of isoindole derivatives: Antioxidant potential and cytotoxicity in the HT-29 colon cancer cells.

Norcantharimides have an isoindole skeleton structure, and some isoindoline derivatives have positive effects on inflammatory pathologies, including cancers. The present study aims to evaluate the antioxidant and cytotoxic potential of four synthesized isoindoline derivatives (NCTD1-4). HT-29 cells exposed to 10, 50, 100, and 200 µM doses of each derivative were incubated for 24 and 48 h, respectively.

Synthesis and biological evaluation of new chloro/acetoxy substituted isoindole analogues as new tyrosine kinase inhibitors.

We have developed a versatile synthetic approach for the synthesis of new isoindole derivatives via the cleavage of ethers from tricyclic imide skeleton compounds. An exo-cycloadduct prepared from the Diels-Alder reaction of furan and maleic anhydride furnished imide derivatives. The epoxide ring was opened with AcO or AcO/AcCl in the presence of a catalytic amount of HSO in order to yield new isoindole derivatives 8a-d and 9a-d.

Evaluation of Cytotoxic Potentials of Some Isoindole-1, 3-Dione Derivatives on HeLa, C6 and A549 Cancer Cell Lines.

Background: Norcantharimides are known as norcantharidine derivatives and contain an isoindole skeleton structure. Isoindole derivatives have positive effect on inflammatory pathologies including cancers.

Objective: Considering this information, firstly, isoindole derivatives containing different functional groups 4-13 have been synthesized from 2-alkyl/aryl-3a, 4,7,7a-tetrahydro-1H-isoindole-1, 3(2H)-dione.

rac-3,4-trans-Dichloro-1,2,3,4-tetra-hydro-2-naphthyl acetate.

The title compound, C(12)H(12)Cl(2)O(2), has a bicyclic skeleton containing cyclo-hexene and benzene fragments. The cyclo-hexene ring adopts a half-chair conformation with displacements of two atoms out of the least-squares plane of 0.311 (2) and -0.

An intramolecular substitution of hydroperoxy-endoperoxide to a bis-endoperoxide.

[reaction: see text] A new and stereospecific synthesis for bis-endoperoxide has been developed starting from tetrahydronaphthalene. Photooxygenation of tetrahydronaphthalene resulted in the formation of hydroperoxy-endoperoxide. The bromination reaction of hydroperoxy-endoperoxide gave bis-endoperoxide, whose exact configuration has been determined by X-ray analysis.
