    Sammanfattning : New strategies are needed to counter the growing problem of bacterial resistance to antibiotics. One such strategy is to design compounds that target bacterial virulence, which could work separately or in concert with conventional bacteriostatic or bactericidal antibiotics. LÄS MER

    Sammanfattning : Many of the drugs that are developed in the pharmaceutical industry have their origin in natural products. Paclitaxel, the active substance of the medicine Taxol, was found in the bark of the Pacific yew tree (Taxus brevifolia). LÄS MER

  4. 4. Optimering i organisk syntes betingelser, system, syntesvägar

    Detta är en avhandling från Organic Chemistry, Lund University

    Författare :Lars Hansson; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Optimization; Response surface method; PLS method; Silylation; Enolether; Unsaturated ketones; Diketones; Geosmin synthesis; Onepot procedure;

    Sammanfattning : This thesis deals with different optimization problems encountered in organic synthesis. The use of response surface, sequential simplex and PLS techniques, for simultanious optimization of yield and suppression of side reactions is investigated. This is illustrated by an example of enamine synthesis, were a side reaction was a serious problem. LÄS MER
