  • Patent number: 10961214
    Abstract: Newly synthesized derivatives of BAS00127538 have been discovered to possess antibiotic activity and to combat resistant bacterial strains. Compounds and pharmaceutical compositions containing these compounds are described, and are based on a generic scaffold structure. Synthetic methods and methods of using the compounds also are described. Preferred compound 6jc48-1 ((E)-2,4-bis(4-bromophenyl)-6-(4-(dimethyl-amino)styryl)pyrylium boron tetrafluoride salt) binds to Lipid II with high affinity, has markedly reduced cytotoxicity than BAS00127538, and retains activity against drug-resistant strains of Enterococci. It is stable in plasma, has dramatically improved pharmacokinetic and pharmacodynamics properties, and possesses in vivo efficacy in a mouse model of sepsis.

  • Patent number: 8785499
    Abstract: The emergence of multidrug-resistant pathogens necessitates the search for new antibiotics acting on previously unexplored targets. Nicotinate mononucleotide adenylyltransferase of the NadD family, an essential enzyme of NAD biosynthesis in most bacteria, was selected as a target for structure-based inhibitor development. To this end, the inventors have identified small molecule compounds that inhibit bacterial target enzymes by interacting with a novel inhibitory binding site on the enzyme while having no effect on functionally equivalent human enzymes.

  • Publication number: 20070066616
    Abstract: Provided herein are compounds and methods of using compounds that selectively inhibit binding to one or more docking domain regions of an extracellular signal-regulated kinase (ERK) to inhibit in a cell having an extracellular signal-regulated kinase activity. Such methods may be used to inhibit cell proliferation of a neoplastic cell, to treat a cancer and further may be used in conjunction with administration of an anticancer drug at a reduced dosage to treat a cancer with a concomitant reduction in toxicity to an individual receiving the treatment. Also provided is a method to design and screen for compounds to inhibit binding within the extracellular signal-regulated kinase docking domain region, using at least in part computer-aided drug design modeling.
