We previously reported the design and discovery of three series of 5-carbon linker-containing mono-carbonyl analogs of curcumin (MCACs) as excellent anti-inflammatory agents. In continuation of our ongoing research, we designed and synthesized the fourth series of MCACs, whose central linker is a piperid-4-one. Their inhibitory effects against IL-6 production were evaluated in lipopolysaccharide (LPS)-stimulated macrophages. Among them, compounds F8, F29, F33, F35, and F36 exhibited the IC50 values under 5 mu M. The structure-activity relationship was discussed. Mechanistically, F35 and F36 dose-dependently prevented LPS-induced NF-kappa B and ERK activation. Finally, pretreatment with F35 and F36 significantly protected the C57B/L6 mice from LPS-induced septic death. Together, these data present a series of new analogs of curcumin as promising anti-inflammatory agents. (C) 2013 Elsevier Ltd. All rights reserved.

Design, synthesis, and evaluation of NDGA analogues as potential anti-ischemic stroke agents
supplementation of antioxidants with ROS scavenging activity would be a potential therapy to cerebral ischemia-reperfusion injury in stroke. In the present study, a series of NDGA analogues with attenuation oxidative stress by directly scavenging ROS and indirectly through keap1/Nrf2/ARE pathway activation were designed and synthesized. All analogues were found to effectively remove ROS directly by DPPH radical
