Two G-quadruplex ligands [Pt(La)(DMSO)Cl] (Pt1) and [Pt(Lb)(DMSO)Cl] (Pt2) have been synthesized and fully characterized. The two complexes are more selective for SK-OV-3/DDP tumor cells versus normal cells (HL-7702). It was found that both Pt1 and Pt2 could be a telomerase inhibitor targeting G-quadruplex DNA. This is the first report demonstrating that telomeric, c-myc, and bcl-2 G-quadruplexes and caspase-3/9 preferred to bind with Pt2 rather than Pt1, which also can induce senescence and apoptosis. The different biological behavior of Pt1 and Pt2 may correlate with the presence of a 6-hydroxyl group in Lb. Importantly, Pt1 and Pt2 exhibited higher safety in vivo and more effective inhibitory effects on tumor growth in the HCT-8 and NCI-H460 xenograft mouse model, compared with cisplatin. Taken together, these mechanistic insights indicate that both Pt1 and Pt2 display low toxicity and could be novel anticancer drug candidates.

N-substituted phthalimides showed peroxisome proliferator-activated receptors-γ activation in rat liver epithelial Ac2F cells in our previous study. In order to explore better peroxisome proliferator-activated receptors-γ agonists, new N-substituted phthalimide derivatives were designed and synthesized based on a pharmacophore study of natural peroxisome proliferator-activated receptors-γ agonist paecilocin A and synthetic leads. Peroxisome proliferator-activated receptors-γ activation by the new derivatives was evaluated using rat liver epithelial Ac2F cells at a concentration of 10 μM (same as previous study). All the new derivatives showed comparable or better activities than that of rosiglitazone, in which 3-hydroxy-N-(p-methoxy-phenethyl) phthalimide (compound 6) appeared as the best. Molecular docking suggested that the free hydroxyl group on the phthalimide head, a proper hydrophobic tail including a phenyl linker, were beneficial for peroxisome proliferator-activated receptors-γ activation. These N-substituted phthalimide derivatives are valuable as scaffolds for new peroxisome proliferator-activated receptors-γ agonists.
