标题 :Bio-intermediates for use in the chemical synthesis of polyketides
发明人：SANTI DANIEL; ASHLEY GARY; MYLES DAVID C
摘要:The present invention relates to compounds made by a subset of modules from one or more polyketide synthase (“PKSâ€?) genes that are used as starting material in the chemical synthesis of novel molecules, particularly naturally occurring polyketides or derivatives thereof. The biologically derived intermediates (“bio-intermediatesâ€?) generally represent particularly difficult compounds to synthesize using traditional chemical approaches due to one or more stereocenters. In one aspect of the invention, an intermediate in the synthesis of epothilone is provided that feeds into the synthetic protocol of Danishefsky and co-workers. In another aspect of the invention, intermediates in the synthesis of discodermolide are provided that feed into the synthetic protocol of Smith and co-workers. By taking advantage of the inherent stereochemical specificity of biological processes, the syntheses of key intermediates and thus the overall syntheses of compounds like epothilone and discodermolide are greaty simplified.

标题 :Biosynthesis of polyketide synthase substrates
发明人：KHOSLA CHAITAN; PFEIFER BLAINE
摘要:The use of enzymes which catalyze the production of starter and extender units for polyketides is described. In addition, modified loading modules are described, which can accept a variety of starting units such as substituted benzoates, and which can be used to generate substituted derivatives of natural products. These enzymes may be used to enhance the yield of polyketides that are natively produced or polyketides that are rationally designed. By using these techniques, the synthesis of a complete polyketide has been achieved in E. coli . Production can be enhanced in microbial organisms of polyketides and other secondary metabolites by delaying production until after exponential phase and by maintaining relatively constant nutrient levels in the medium. In addition, polyketide production can be enhanced by providing an expression system for a thioesterase II. Thus, by modifying the host organism and changing the culture conditions, synthesis of a secondary metabolite can be enhanced. The present invention also results in a host organism with desirable characteristics to be used in the production of such polyketides and to assess the results of gene shuffling.

标题 :Method for treatment and prevention of acute and chronic pseudomonas aeruginosa airway infections with inhalable macrolides

摘要:Macrolides, in particular azalides such as azithromycin, are suited for the treatment or prevention of acute or chronic P. aeruginosa infections of the airways by inhala­tion. The mechanism of action is the inhibition of the quo­rum sensing of P. aeruginosa, in particular the impediment of the las and rhl quorum sensing systems synthesis and the impediment of the synthesis of the autoinducers N-[3-oxodo­1o decanoyl]-L-homoserine lactone and N-butyrylhomoserine lac­tone. This allows for inhalation treatments of P. aerugi-nosa infections at non-inhibiting concentrations of the macrolide.
