A group of cyclic imides (1–13) was designed for evaluation as selective COX-2 inhibitors and investigated in vivo for their anti-inflammatory activities using carrageenan-induced rat paw edema model. Compounds 5b, 6b, 11b, 11c, 12b and 12c were proved to be potent COX-2 inhibitors with IC50 range of 0.1–1.0 μM. In vitro COX-1/COX-2 inhibition structure–activity studies identified compound 5b as a

Carboxylic acid imides 1-26 have been synthesized and screened for their antibacterial against gram-positive and gram-negative organisms and their antitumor activity against 60 tumor cell lines taken from nine different organs. Compounds 12, 14, and 16 were the most active and broad-spectrum antibacterial member in this study. Compound 9 showed the most cytotoxicity with a significant inhibition for renal cancer cells. 2D-QSAR study provides details on the fine relationship linking structure and activity and offers clues for structural modifications that can improve the activity. Docking study of the compounds 12, 14, and 16 into the active site of the topoisomerase II DNA gyrase enzymes revealed a similar binding mode to bound inhibitor Clorobiocin.

As well as deoxygenations, olefinations are reported which are E-selective and can be made Z-selective in a tandem reduction/photosensitization process where both steps are photoelectrochemically promoted. Spectroscopy, computation, and catalyst structural variations reveal that our new naphthalene monoimide-type catalyst allows for an intimate dispersive precomplexation of its radical anion form with
