A novel series of 3-alkyl-substituted 7-phenyl-3H-pyrrolo[3,2-jlquinolin-9-ones (7-PPyQs) was synthesized with the aim to optimize the cytotoxic activity of recently identified PPyQs, promising inhibitors of tubulin polymerization. All compounds inhibited the growth of 11 human tumor cell lines at submicromolar concentrations as well as two human resistant cancer sublines, A549-T12 and A549-T24. FACS analysis indicated that all compounds caused significant arrest of the A549 cell cycle in G(2)/M phase at 0.1 and 1 mu M and a good correlation between the cytotoxicity IC50 and their ability to block the cell cycle was observed.

Synthesis and Antioxidant Activity of New Tetrahydro-Naphthalene-Indole Derivatives as Retinoid and Melatonin Analogs
proapoptotic agents with promising potential in the treatment of neoplastic diseases. Indeed, the synthetic retinoid amide fenretinide [N‐(4‐hydroxyphenyl)retinamide] induces apoptosis of cancer cells and acts as a chemotherapeutic drug in cancer therapy. In the present work, and as a continuation of our studies on retinoid‐type compounds, the synthesis of melatonin retinamide derivatives was studied
properties of conjugates based on indole and lipoic acid moieties. The design and syntheses of novel indole α‐lipoic acid derivatives were performed. The antioxidant properties of target compounds were investigated using rat liver microsomal, NADPH‐dependent lipid peroxidation inhibition. Some of the target compounds, especially those containing amide linker at position 5 of indole ring, proved to be highly
