Discovery Of Novel Muraymycin Antibiotics And Insight Into The Biosynthetic Pathway, Zheng Cui

Theses and Dissertations--Pharmacy

New antibiotics with novel targets or mechanisms of action are needed to counter the steady emergence of bacterial pathogens that are resistant to antibiotics used in the clinic. MraY, a promising novel target for antibiotic development, initiates the lipid cycle for the biosynthesis of peptidoglycan cell wall, which is essential for the survival of most, if-not-all, bacteria. MraY is an enzyme that catalyzes the transfer and attachment of phospho-MurNAc-pentapeptide to a lipid carrier, undecaprenylphosphate. Muraymycins are recently discovered lipopeptidyl nucleoside antibiotics that exhibit remarkable antibiotic activity against Gram-positive as well as Gram-negative bacteria by inhibiting MraY. We conducted a thorough ...

Progress Toward The Development Of A "Catch/Release" Strategy For Isolating Salvinorin A, From Plant Materails Including Microwave Promotion, Douglas Armstrong, Logan Smith

Faculty Scholarship – Chemistry

We are investigating using the Diels-Alder and retro-Diels-Alder reactions as a potential “catch/release” strategy for isolating Salvinorin A from plant samples (Salvia divinorum), hopefully to improve the current method, which is very long and laborious. Salvinorin A has analgesic activity by activating the kappa opioid receptor, not the mu receptor, and thus it has potential for being developed into a non-addicting analgesic.

Streptococcus mutans JH1140 is a strain of bacteria which produces a lantibiotic product, named mutacin 1140. Mutacin 1140 has been shown to be effective at inhibiting Gram-positive bacterial infections caused by Staphylococcus aureus and Streptococcus pneumoniae. Mutacin 1140 is a ribosomally synthesized peptide antibiotic that undergoes extensive posttranslational modifications (PTM). We have found that Mutacin 1140 and an aminoglycoside, Kanamycin, when combined together, act synergistically against Staphylococcus aureus. This was determined by performing serial kill curve dilution overlays on solid media, followed up with kill curve by microdilution plate, and most recently confirmed with kill curve CFU count plates on ...
