Abstract: The subject invention provides fluorophore-quencher nucleic acid molecules comprising relaxed or supercoiled DNA molecules, and their use in rapid and efficient high-throughput screening (HTS) assays to screen and identify compounds that inhibit DNA gyrases. These compounds can be used as antibiotics for treating bacterial infections, especially, multidrug resistant bacterial infections.

Abstract: Provided herein are compositions to treat Clostridioides difficile (C. difficile), Mycobacterium tuberculosis (M. tuberculosis) and Enterococcus faecalis (E. faecalis). These compositions are related to the known compounds (+)-Puupehenone and (+)-ent-Chromazonarol, which are both naturally occurring products. The new compositions were shown to potently inhibit both growth and toxin production of C. difficile as well as inhibit the growth and survival of both replicating and dormant M. tuberculosis. In the United States the C. difficile burden is approximately 453,000 hospital cases and 29,000 deaths annually. Globally, about 10 million people fall ill from tuberculosis and 1.4 million died from the disease. In addition, the known compound (+)-ent-Chromazonarol (10) was found for the first time to strongly inhibit the growth of E. faecalis. E. faecalis has grown drug resistant to vancomycin.

Abstract: The present disclosure provides methods for the treatment of infections with Mycobacterium such as tuberculosis or leprosy.

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.
