A series of new bromophenols and chlorophenols were prepared by a practical route. The in vitro antioxidative activity of the halophenols was evaluated by the 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical-scavenging assay, and their cytoprotective activity was also tested on hydrogen peroxide (H2O2)-induced injury in human umbilical vein endothelial cells (HUVEC). All halophenols tested displayed moderate to good DPPH radical-scavenging activity, and two bromophenols, 2,3'-dibromo-4,5,6'-trihydroxydiphenyl-methanone (16c) and 2,3-dibromo-4,5-dihydroxydiphenylmethanone (17c) exhibited high protective activity against H2O2-induced injury in HUVEC with EC50 values of 0.4 and 0.8 mu M, respectively. The preliminary structure-activity relationships of these compounds were also investigated in order to determine the essential structures required for their bioactivities. (C) 2010 Elsevier Ltd.

Medical applications of 2,5′-dibromo-4,5,2′-trihydroxyldiphenylmethanone and 4,5,2′-tris(4-morpholinemethanoyl)-2,5′-dichlorobenzophenone are provided, particularly applications in preparation of drugs respectively for resisting type II diabetic nephropathy and for treating acute pyelonephritis and chronic nephritis. Moreover, two drugs respectively with the above two compounds as the active ingredient are provided, respectively for resisting the type II diabetic nephropathy and for treating the acute pyelonephritis and the chronic nephritis. Both of the two compounds are able to effectively improve renal functions of model rats suffered from the type II diabetic nephropathy, the acute pyelonephritis, and the chronic nephritis, showing an important application prospect in resisting the diabetic nephropathy and treating the acute pyelonephritis and the chronic nephritis.
