  2. 1. On the pro-apoptotic mechanisms of the antitumor drugs doxorubicin and interferon-alpha

    Author : Theocharis Panaretakis; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Anti-cancer drugs act primarily by inducing apoptosis. However, knowledge of how various substances induce apoptosis is still incomplete, and so is the basis for the great variation in cellular sensitivity to cytotoxic drugs. READ MORE

  4. 2. Synthesis of Bioactive Analogues of Marasmane Dialdehydes

    Author : Daniel Röme; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organisk kemi; Organic chemistry; Cancer; Enantioselective synthesis; Totalsynthesis; Semisynthesis; Cytotoxicity; Anti-tumor activity; Isovelleraloids; Marasmic acid; Marasmane dialdehydes; Isovelleral;

    Abstract : The modification of drugs into pro-drugs is an attractive concept allowing you to tweak the chemical and physical properties of a drug without changing the original structure of the active compound. In principle, any compound possessing a preferred biological activity can be transformed into a pro-drug. READ MORE

  5. 3. Analyses of Dose-Response and Mechanistic Action of Different Anti-Cancer Drugs for Neuroendocrine Tumor Cell Lines

    Author : Dhana E Larsson; Dan Granberg; Sadia Hassan; Kjell Öberg; Jens F Rehfeld; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cancer drugs; Screening; Hollow Fiber model; Apoptosis; Oncology; Onkologi;

    Abstract : Cancer is a disease with poor response rates on available treatments. Problems with resistance and intolerance against cancer drugs are major reasons for failure of the drugs. The need to discover new cancer drugs is important. In this thesis screening of new cancer drugs and evaluation of their mechanism of action are discussed. READ MORE

  6. 4. Investigating novel roles of topoisomerase regulatory interactions in transcription

    Author : Vladislav Kuzin; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Drugs targeting DNA Topoisomerases (TOPs, TOP1 and TOP2) are mainstays of anti-cancer therapy. While they have proven effective, the toxicity of current TOP drugs caused by DNA damage-induced apoptosis of non-cancer cells, limits their use in the clinic. READ MORE

  7. 5. Methods for Preclinical Evaluation of Cytotoxic Drugs : With Special Reference to the Cyanoguanidine CHS 828 and Hollow Fiber Method

    Author : Saadia Bashir Hassan; Elin Lindhagen; Rolf Larsson; Mats O Karlsson; Mustapha Hassan; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacology; CHS 828; in vitro; in vivo; hollow fiber; models; NF-kB; Farmakologi; Pharmacological research; Farmakologisk forskning;

    Abstract : The novel cyanoguanidine CHS 828 has shown promising antitumor activity in many in vitro and in vivo studies. The long-term 14 days in vitro hollow fiber cultures, where tumor cells from different tumor cell lines were cultured inside semipermeable fibers, were more resistant to CHS 828 and other cytotoxic drugs than the shorter-term 3 days cultures.
