3. 12. Drug Repositioning for Cancer Treatment : Novel Candidate Identification Strategies

   Författare :Madiha Nazir; Mårten Fryknäs; Sigurd Vitols; Uppsala universitet; []
   Nyckelord :cancer treatment; drug repositioning; Phosphodiesterase 3A PDE3A ; apoptosis; combination screening;

   Sammanfattning : Regardless of the enormous investments in cancer research and drug development, the proportion of approved drugs in oncology is low compared to other indications, and new avenues are needed. One attractive approach in this regard is drug repositioning where new uses outside the scope of the original medical indications for existing drugs are identified. LÄS MER

4. 13. Conformationally Constrained Nucleosides : Design, Synthesis, and Biochemical Evaluation of Modified Antisense Oligonucleotides

   Författare :Oommen P. Varghese; Lars Engman; Jacek Stawinski; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; chemically modified oligonucleotides; azetidine; aza-ENA-T; cyanomethylene locked; free energy of activation; diaxial interactions; chair conformation; stable duplex; human serum; snake venom phosphodiesterase; antisense agents; RNase H; Organisk kemi; Chemistry; Kemi;

   Sammanfattning : This thesis is concerned with synthesis, structure and biochemical analysis of chemically modified oligonucleotides with potential therapeutic applications. The three types of chemical modifications described here are: (a) A North-East locked 1',2'-azetidine nucleoside (b) A North locked 2',4'-cyanomethylene bridged nucleoside and (c) A 2',4'-aza-ENA-T nucleoside.

5. 14. Vardenafil and methylarginines in pulmonary hypertension

   Författare :Anna Sandqvist; Gerhard Wikström; Jörn Schneede; Amrita Ahluwalia; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; vardenafil; pulmonary hypertension; pharmacokinetics; haemodynamics; right heart catheterization; adenosine; dimethylarginines; phosphodiesterase type 5 inhibitors; endothelin receptor antagonists; klinisk farmakologi; Clinical Pharmacology;

   Sammanfattning : Background: Pulmonary hypertension (PH) is a rare condition characterized by endothelial dysfunction and vascular remodelling, leading to increased pulmonary vascular resistance (PVR) and right ventricular heart failure. Endothelial dysfunction is associated with an imbalance between vasoconstrictor compounds, such as endothelin and thromboxane A2, and vasodilator compounds, such as prostacyclin and nitric oxide (NO).
