  1. 1. Terpenoid Conidiation Factors in Penicillium cyclopium

    Författare :Yanhong He; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; acetals; hydrolysis; Biotechnology; Bioteknik; total synthesis; analogues; synthesis; conidiogenone; conidiogenol; terpenoid; Penicillium cyclopium; conidiation inducing activity; Natural product; fungal metabolites;

    Sammanfattning : Filamentous fungi produce asexual dispersive spores (conidia), when conditions are not suitable for apical extension growth. Conidiation (the process by which conidia produced) in genus Penicillium has attracted considerable interest because of its wide usage in different areas. LÄS MER

  3. 2. Lipase catalysed reactions of terpenoids : formation of hemiacetal esters : resolution of cryptone and its transformation to cadinenes

    Författare :Dan Isaksson; Fredrik Almqvist; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; terpenoid; lipase; resolution; hemiacetal; hemiacetal ester; enantioselective; synthesis; cryptone; cadinene; Organic chemistry; Organisk kemi;

    Sammanfattning : During attempted enzyme-catalysed resolution of sterically hindered secondary alcohols, hemiacetals and their esters were unexpectedly detected. Hemiacetal esters are reactive compounds that decompose to alcohol, aldehyde and acid under ordinary work-up conditions i.e. in contact with water, acid, or silica gel. LÄS MER

  4. 3. Terpenoid Plant Metabolites - Structural Characterization and Biological Importance

    Författare :Eliana Maldonado; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Terpenoid Sesquiterpene lactones Breast-cancer cell lines Cytotoxicity Antileishmanicial Structural characterization;

    Sammanfattning : In response to the challenges of their local environments, organisms produce of a large number of chemical diverse compounds with complex stereochemistry and reactive functional groups. These characteristics enable them to interact and bind specifically to biological target molecules and exert various biological activities, and have assured that Natural products continues to be an important source of bioactive compounds, which, for example, facilitate the search for new lead structures that can be developed into new pharmaceuticals.

  5. 4. Engineering Synechocystis sp. PCC 6803 for microbial terpenoid production

    Författare :João S. Rodrigues; Pia Lindberg; Patrik R. Jones; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Synechocystis; metabolic engineering; bisabolene; isoprene; cyanobacteria; Chemistry with specialization in Microbial Chemistry; Kemi med inriktning mot mikrobiell kemi;

    Sammanfattning : As part of the efforts to develop a carbon-neutral economy, photosynthetic microorganisms such as cyanobacteria have been extensively studied as solar-powered cell factories for the production of organic compounds with industrial interest, using the atmospheric CO2 as carbon source.Among other metabolites, cyanobacteria produce terpenoids, a diverse group of natural products that play pivotal roles in the cell.

  7. 5. Metabolic Engineering of Synechocystis sp. PCC 6803 for Terpenoid Production

    Författare :Elias Englund; Pia Lindberg; Annegret Wilde; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Metabolic engineering; Cyanobacteria; Synechocystis; Terpenoids; Genetic tools; Mikrobiologi; Microbiology;

    Sammanfattning : In the Paris Agreement from 2015, nations agreed to limit the effects of global warming to well below 2°C. To be able to reach those goals, cheap, abundant and carbon neutral energy alternatives needs to be developed. LÄS MER
