Binary mixtures of model systems consisting of the antibiotic ampicillin with either Escherichia coli or Staphylococcus auresu were subjected to pyrolysis mass spectrometry (PyMS). To deconvolute the pyrolysis mass spectra, so as to obtain quantitative information on the concentration of ampicilin in the mixtures, partial least squares regression (PLS),(More)
Two diketopiperazines, XR334 (1) and the novel compound XR330 (2), were isolated from the lyophilised biomass of an unidentified Streptomyces sp. Their structures were elucidated on the basis of spectroscopic studies and confirmed by chemical synthesis. Both compounds inhibited plasminogen activator inhibitor-1 activity in an amidolytic assay of tissue(More)
A series of halogenated pyrrolo [2,1-b] [1,3] benzoxazines (1 approximately 9) was isolated from fermentations of an actinomycete strain X10/78/978 (NCIMB40808), identified as Streptomyces rimosus, during a microbial extract screening programme to identify inhibitors of bacterial histidine kinase. The structures of these compounds were elucidated by(More)
