strategies are urgently needed. During a project aiming at discovery of anticancer agents, we performed a structure modification on polycyclic polyprenylated acylphloroglucinols (PPAPs) skeleton, and discovered that PPAP rearranged to a tetrahydroquinolin-2(1H)-one feature. Here, series of tetrahydroquinolin-2(1H)-one derivatives were designed, synthesized and evaluated against a highly metastatic human

A structure-based virtual screening of commercial compounds was carried out on the HCV NS3 helicase structure, with the aim to identify novel inhibitors of HCV replication. Among a selection of 13 commercial structures, one compound was found to inhibit the subgenomic HCV replicon in the low micromolar range. Different series of new piperazine-based analogues were designed and synthesised, and among them, several novel structures exhibited antiviral activity in the HCV replicon assay. Some of the new compounds were also found to inhibit HCV NS3 helicase function in vitro, and one directly bound NS3 with a dissociation constant of 570 +/- 270 nM. (C) 2016 Elsevier Masson SAS.

specific biomolecular target of CADA compounds is unknown, but previous studies led to an unsymmetrical binding model. To test this model, methods were developed for effective synthesis of diverse, unsymmetrical CADA compounds. A total of 13 new, unsymmetrical target compounds were synthesized, as well as one symmetricalanalogue. The new compounds display a wide range of potency for CD4 down-modulation
