  • Patent number: 11234966
    Abstract: The present invention includes a composition, method of making and method of using a novel C5-substituted carbapenem antibiotic of formula 1: R1 is H or CH3 R2 is not H, and is CH3, or C1-C6 straight chain, or branched alkyl, or C3-C6 cycloalkyl group, or unsaturated alkenyl, including C?CH2; R3 is H, CH3, or a C1-C6 alkyl or cycloalkyl group, a heteroatom-substituted alkyl; and R4 is a C1 to C6 alkyl, or substituted alkyl group, especially including substituents which possess positive charge, or a hydroxyl group; or R4 is an SRa, where Ra is an unsubstituted C1 to C6 alkyl group, a substituted C1 to C6 alkyl group, or a functional group that is positively charged, or which bears a positive charge when in aqueous solution at pH 7; or R4 is a CH2ORb, where Rb=C1 to C6 alkyl or substituted alkyl groups, substituted or unsubstituted aryl, or a heteroaryl groups.

  • Publication number: 20200339582
    Abstract: The following invention deals with the design, preparation, evaluation, and use of carbapenem antibiotics with improved activity, relative to current commercially available carbapenem antibiotics, against infections involving multidrug resistant, carbapenemase-producing Acinetobacter baumannii. The new carbapenem antibiotics are demonstrated to possess not only inherent antimicrobial activity, but also the ability to inhibit OXA-23, the most commonly produced serine carbapenemase in this species. This unusual carbapenemase-inhibitory activity also indicates that the compounds may be used synergistically, in combination with current commercial carbapenem antibiotics, to inhibit key class D carbapenemases, such as OXA-23. Additionally, one of the newly reported carbapenems is active against metallo-beta-lactamase producing A. baumannii. This is the first report of a metallo-beta-lactamase stable carbapenem antibiotic.
