  1. 1. Synthetic studies towards 7- and 8-membered N-heterocycles, particularly 1,4-pyrrolobenzodiazepines : total synthesis of fuligocandin A and B

    University dissertation from Stockholm : Karolinska Institutet, Dept of Biosciences and Nutrition

    Author : Birgitta Pettersson; Karolinska Institutet.; Karolinska Institutet.; [2011]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 1; 4-pyrrolobenzodiazepines;

    Abstract : This dissertation is concerned with the synthesis of 7- and 8-membered N-heterocycles, particularly 1,4-pyrrolobenzodiazepines. A non-chromatographic method for conversion of carbonyl-functionalities to the corresponding thiocarbonyls is described. READ MORE

  2. 2. Cellular toxicity of quinones : Redox- and addition chemistry

    University dissertation from Linköping : Linköpings universitet

    Author : Karin Öllinger; Linköpings universitet.; Linköpings universitet.; [1992]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICINE; MEDICIN;

    Abstract : Quinoid compounds are widely occurring in nature. They have cytotoxic properties and they are also used as antineoplastic agents. The cytotoxic properties can be explained by the ability of quinones to generate active oxygen species by redox cycling, by addition to cellular nucleophiles, and by inhibition of DNA transcription.

    Abstract : Popular Abstract in Swedish Sammanfattning. Man brukar mena att domsförkunnelsen i Jesaja 1?39 har två brännpunkter. I det jag kallar den samhällskritiska diskursen fördöms överklassens livsstil i allmänhet och dess förtryck av de fattiga i synnerhet. READ MORE

  4. 4. The Influence of Salting Procedures on the Characteristics of Heavy Salted Cod

    University dissertation from Department of Food Technology, Engineering and Nutrition, Lund University

    Abstract : Popular Abstract in Swedish Asymmetrisk katalys är ett omfattande forskningsområde där ett flertal olika typer av enantioselektiva katalysatorer har utvecklats och använts i en mängd olika kemiska reaktioner med varierande resultat. Det finns ingen katalysator som fungerar lika väl i alla applikationer, utan resultaten varierar från fall till fall och för vissa typer av substrat behövs det därför alternativa lösningar för att erhålla önskad selektivitet.
