Publication number: 20160039857Abstract: With the rise in resistance to antibiotics such as methicillin, there is a need for new drugs. The invention provides small molecules that inhibit cellular drug targets such as UPPS and FPPS by interacting with binding pockets, thereby preventing enzyme function. Compounds described herein are also active against Staphylococcus aureus (MIC90˜0.25 ?g/mL), can potently synergize with methicillin (fractional inhibitory concentration index=0.25), and are protective in a mouse infection model. The invention therefore provides numerous compounds for anti-bacterial treatments and for restoring sensitivity to drugs such as methicillin, using combination therapies.Type: ApplicationFiled: December 4, 2013Publication date: February 11, 2016Applicants: THE BOARD OF TRUSTEES OF THE UNIVERSITY OF ILLINOIS, THE REGENTS OF THE UNIVERSITY OF CALIFORNIAInventors: Wei Zhu, Steffen Lindert, Yonghui Zhang, William Sinko, Kai Li, James Andrew McCammon, Eric Oldfield

Patent number: 7687482Abstract: The invention provides, inter alia, novel bisphosphonate compounds and methods of making and using. In embodiments, the invention provides compounds and methods in connection with research and therapeutic applications, e.g., for tumor cell growth inhibition, activation of gammadelta T cells, inhibition of farnesyldiphosphate (FPPS) and/or undecaprenyldiphosphate synthase enzymes, bone resorption diseases, cancer, immune disorders, immunotherapy, and infectious diseases. In regards to certain embodiments, a surprising advance has been the recognition that certain structural features can significantly enhance the activity of the compounds. For example, the presence of particular cationic species e.g., phosphonium, sulfonium, and arsonium moieties can contribute to desirable functional activity when positioned near a bisphosphonate moiety. In other embodiments of non-nitrogen containing bisphosphonates, terphenyl and benzyl bisphosphonate compounds and methods are provided. Further variations are also provided.Type: GrantFiled: March 16, 2007Date of Patent: March 30, 2010Assignee: The Board of Trustees of the University of IllinoisInventors: Eric Oldfield, Yongcheng Song, Yonghui Zhang, John M.
