Functional characterization of synthetic leukotriene B and its stereochemical isomers. [PDF]
Leukotriene B (LTB), a potent lipid chemotactic factor for neutrophils, is 5S,12R-dihydroxy-6,14-cis,8,10-trans-eicosatetraenoic acid (Fig 1), based upon direct comparison of natural LTB with synthetic 5S,12R-dihydroxy-6,8,10,14-eicosatetraenoic acid (5 ...

Synthesis of cyclopropyl-substituted furans by Brønsted acid promoted cascade reactions [PDF]
Chloroacetic acid promotes an efficient and diastereoselective intramolecular cascade reaction of electron-deficient ynenones to deliver products featuring a 2,3,5-trisubstituted furan bearing a fused cyclopropyl substituent at the 5-position ...

Synergistic Anti-Candida Activity of Bengazole A in the Presence of Bengamide A †. [PDF]
Bengazoles A⁻G from the marine sponge Jaspis sp. exhibit potent in vitro antifungal activity against Candida spp. and other pathogenic fungi. The mechanism of action (MOA) of bengazole A was explored in Candida albicans under both liquid culture and ...

The Sequence of the Enterococcal Cytolysin Imparts Unusual Lanthionine Stereochemistry
The enterococcal cytolysin is a two-component lantibiotic of unknown structure with hemolytic activity that is important for virulence. We prepared cytolysin by co-expression of each precursor peptide with the synthetase CylM in E.
