Patent number: 9682079Abstract: The invention relates to compounds and pharmaceutical compositions useful in combination with tetracyclines in the treatment of bacterial infections caused by Gram-positive and Gram-negative pathogens, with particular efficacy in tetracycline resistant strains. These compounds specifically bind to TetR and therefore prevent the transcriptional activation of tet resistance genes. The compounds have a potentiating effect on the activity of members of the tetracycline family, in particular of tetracycline, minocycline, doxycycline and tigecycline, in the treatment of tetracycline susceptible, intermediate and tetracycline resistant pathogens.Type: GrantFiled: February 3, 2014Date of Patent: June 20, 2017Assignee: BIOVERSYS AGInventors: Peter Schneider, Rainer Riedl, Marcel Tigges, Marc Gitzinger, Michel Pieren, Assaf Levi, Mark Sephton, Birgit Schellhorn, Patrik Zueger, Michael Brand, Daniel Gygax, Peter Spies
