Diversity-oriented synthesis (DOS), which describes the synthesis of structurally diverse collections of small molecules, was developed, in part, to address combinatorial chemistry's shortfalls. In this paper, we hope to give an indication of what can be achieved using the DOS approach to library generation. We describe some of the most successful… (More)
Pseudomonas aeruginosa produces the quorum sensing signalling molecule N-(3-oxododecanoyl)-L-homoserine lactone (OdDHL). This natural product not only coordinates production of virulence factors by the bacterium, but also has immunomodulatory effects on the host organism. Immunomodulatory small molecules are valuable for immunology research and are… (More)
There is a paucity of chemical matter suitably poised for effective drug development. Improving the quality and efficiency of research early on in the drug discovery process has been a long standing objective for the drug industry and improvements to the accessibility and quality of compound screening decks might have a significant and positive impact. In… (More)
The search for new molecular entities in drug discovery and chemical genetic programs requires the screening of high-quality collections of structurally diverse small molecules. The design and synthesis of such collections remains a major challenge to synthetic chemists. Recent strategies and results are presented in the context of the chemical space being… (More)
Over the last decade or so, a wealth of research has established that bacteria communicate with one another using small molecules. These signals enable the individuals in a population to coordinate their behaviour. In the case of pathogens, this behaviour may include decisions such as when to attack a host organism or form a biofilm. Consequently, such… (More)
The human pathogen Pseudomonas aeruginosa uses N-butyryl-L-homoserine lactone (BHL) and N-(3-oxododecanyl)-L-homoserine lactone (OdDHL) as small molecule intercellular signals in a phenomenon known as quorum sensing (QS). QS modulators are effective at attenuating P. aeruginosa virulence; therefore, they are a potential new class of antibacterial agent. The… (More)
Production of virulence factors and secondary metabolites is regulated in the phytopathogen Erwinia carotovora by quorum sensing involving N-acylated homoserine lactone (AHL) signaling molecules. Non-hydrolyzable AHL analogues were synthesized and screened in vivo. The biological activity of each compound was correlated with its ability to bind Erwinia AHL… (More)
The screening of a diversity-oriented synthesis library followed by structure-activity relationship investigations have led to the discovery of an anti-MRSA agent which operates as an inhibitor of Staphylococcus aureus dihydrofolate reductase.
Through the synthesis of a focused library and SAR investigations, a more potent analogue of gemmacin (discovered in a previous diversity-oriented synthesis (DOS) campaign), gemmacin B, was discovered.
