  Synthesis of chromone carboxamide derivatives with antioxidative and calpain inhibitory properties

  摘要：

  The overactivation of mu-calpain can cause serious cell damage in several diseases. Furthermore, cell death in a number of neurodegenerative disorders is linked to the overproduction of reactive oxygen species. Therefore, antioxidants and mu-calpain inhibitors could have the therapeutic potentials to treat cell death related diseases. New chromone carboxamide derivatives 3 were synthesized to provide alternative mu-calpain inhibitors to compound 2, a conformationally constrained structural variant of MDL 28,170. Compounds 3h and 3l exhibited the most potent p-calpain inhibitory activities (IC50 = 0.09-0.10 mu M), and were comparable to 2 in this respect (IC50 = 0.07 mu M). Compound 31 showed both potent p-calpain inhibitory activity (IC50 = 0.28 mu M) and antioxidant activities in DPPH scavenging and lipid peroxidation inhibition assays. (C) 2011 Elsevier Masson SAS.
