  2. 21. Synthesis of C(sp2)-P bonds by palladium-catalyzed reactions : Mechanistic investigations and synthetic studies

    Author : Marcin Kalek; Jacek Stawinski; Jean-Luc Montchamp; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; Organisk kemi; Organic Chemistry; organisk kemi;

    Abstract : This thesis focuses on synthetic and mechanistic aspects of palladium-catalyzed C(sp2)-P bond-forming reactions, with the aim to develop mild and efficient methods for the synthesis of biologically active phosphorus compounds, e.g. DNA analogs. READ MORE

  4. 22. Towards novel antibacterials : Synthesis and identification of natural product inspired inhibitors of Chlamydia trachomatis and development of chemical probes targeting virulence of Pseudomonas aeruginosa

    Author : Michael Saleeb; Mikael Elofsson; Anna Linusson Jonsson; Andreas Kirschning; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Antibacterials; antibiotics; small molecules; natural products; benzofuran; dihydrobenzofuran; the type III secretion system; Pseudomonas aeruginosa; Chlamydia trachomatis; phenotypic screening; high-throughput screening; surface plasmon resonance; drug discovery; bacterial toxins; enzyme inhibitors; organisk kemi; Organic Chemistry;

    Abstract : Antibiotic resistance has evolved significantly to become one of the serious threats to public health today. Yet, the pipeline of new antibiotics is drying up and is lagging behind the challenging needs. READ MORE

  5. 23. BIOACTIVE SECONDARY METABOLITES -Isolation Characterization and Synthesis

    Author : Carola Valdivia; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organisk kemi; Organic chemistry; Baccharis genistelloides; Piper heterophyllum; Myrtus Communis; Coprinus heptemerus; Thapsia garganica; Piper longestylosum; Piper obliquum; Natural Products;

    Abstract : Nature produces biologically active and chemically intriguing secondary metabolites. To isolate and characterize compounds of novel activity and structure, bioassay-guided fractionations were applied to several plants as well as to a basidiomycete. READ MORE

  6. 24. Studies of different secondary metabolites : Natural products from the mevalonate pathway

    Author : Mariela Alejandra Gonzales Ramirez; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Natural products; fungi; Galiellalactone; Galiella rufa; Trichilia adolfi; benzofuran;

    Abstract : Natural products, also called secondary metabolites, are small molecules that are not involved in main life processes. These can be produced by any living organism and play important roles as chemical weapons, protecting the organism from the competitive environment. READ MORE

  7. 25. Synthesis Towards Biologically Active Natural Products

    Author : Rikard Larsson; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Transtaganolide; basiliolide; natural product; total synthesis; biomimetic; Thapsia; Diels-Alder; Ireland-Claisen; Pictet-Spengler; tetrahydroisoquinoline; indole;

    Abstract : In 2005 two research groups independently reported the isolation of a series of structurally intriguing C-19 terpenolides from the plants Thapsia transtagana and Thapsia garganica. The compounds were shown to be potent inhibitors of the sarco/endoplasmic reticulum Ca2+-ATPases. READ MORE
