  2. 1. Galiellalactone Synthetic Studies

    Author : Zilma Escobar; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; natural product; galiellalactone; prostate cancer; STAT3.;

    Abstract : In search for remedies and treatments, science has recurred to Mother Nature. This is where galiellalactone was found, a fungal metabolite isolated from Galiella rufa in 1990. Since then chemists and biologists have been studying its properties and found it to be a potential candidate against castration-resistance prostate cancer (CRPC). READ MORE

  4. 2. The estrogen receptor in fish and effects of synthetic estrogens in the environment - Ecological and evolutionary perspectives and societal awareness

    Author : Lina Nikoleris; Biodiversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; the estrogen receptor; salmon evolution and ecology; contraceptives; information gaps; synthetic hormones; EE2; Atlantic salmon Salmo salar ; brown trout Salmo trutta ; roach Rutilus rutilus ;

    Abstract : Synthetic hormones are a group of pharmaceuticals used for various human and animal treatments. However, consumption and disposal of these substances have also given rise to negative effects and environmental problems for organisms in the wild which is why these substances have been classified as estrogenic endocrine-disrupting chemicals (EDCs).

  5. 3. The synthetic chromosphere : Results and techniques with a numerical approach

    Author : Johan Pires Bjørgen; Jorrit Leenaarts; Oskar Steiner; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sun; chromosphere; radiative transfer; numerical method; Astronomy; astronomi;

    Abstract : Realistic numerical simulations of the solar atmosphere can be used to interpret different phenomena observed on the solar surface. To gain insight into the atmospheric physical conditions, we compare the observations with 3D radiative magnetohydrodynamic models combined with forward modeling (radiative transfer). READ MORE

  6. 4. The discovery of antiviral compounds targeting adenovirus and herpes simplex virus : assessment of synthetic compounds and natural products

    Author : Mårten Strand; Göran Wadell; Mikael Elofsson; Ya-Fang Mei; Lieve Naesens; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; virology; antiviral; adenovirus; herpes simplex virus; small molecule; inhibitor; hsv; drug discovery; medicinsk virologi; Medical Virology; datorlingvistik; computational linguistics; mikrobiologi; Microbiology;

    Abstract : There is a need for new antiviral drugs. Especially for the treatment of adenovirus infections, since no approved anti-adenoviral drugs are available. Adenovirus infections in healthy persons are most often associated with respiratory disease, diarrhea and infections of the eye. These infections can be severe, but are most often self-limiting.

  7. 5. 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
