  1. 11. Modelling of melanocortin receptors and their ligands

    Författare :Peteris Prusis; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical biosciences; melanocortin; G-protein coupled receptor; modeling; three-dimensional; QSAR; chemometrics; Farmaceutisk biovetenskap; Biopharmacy; Biofarmaci; farmaceutisk farmakologi; Pharmaceutical Pharmacology;

    Sammanfattning : Five subtypes of melanocortin receptors (MC1-MC5R) mediate a wide range of physiological actions, including control of skin tanning, inflammation and food intake. The natural ligands for these receptors are the melanocortins, which are linear peptides 11 to 39 amino acids long. LÄS MER

  3. 12. The Impact of Substance P (SP) N-Terminal Metabolite SP1-7 in Opioid Tolerance and Withdrawal

    Författare :Qin Zhou; Tsukasa Sakurada; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical biosciences; Farmaceutisk biovetenskap; Biopharmacy; Biofarmaci; farmaceutisk biokemi; Pharmaceutical Biochemistry;

    Sammanfattning : The heptapeptide SP1-7, a metabolite of the neuroactive peptide substance P (SP), is suggested to play a role in opioid addiction and memory function. These two dimensions are known to involve dopamine and glutamate transmissions mediated through dopamine receptors and N-methyl-D- aspartate (NNMA) receptors, respectively. LÄS MER

  4. 13. Design and stereoselective syntheses of Phe-Phe dipeptidomimetics

    Författare :Annika Jenmalm Jensen; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical biosciences; Farmaceutisk biovetenskap; Biopharmacy; Biofarmaci; Organic Pharmaceutical Chemistry; organisk farmaceutisk kemi;

    Sammanfattning : Several stereochemically well characterized Phe-Phe dipeptidomimetics have been designed and synthesized. The Phe-Phe vinyl isostere was used as a key intermediate. The synthesized series of mimetics includes two isomeric epoxides, four 1,2-dihydroxyethylene isomers, two isomeric allylic alcohols and two isomeric allylic fluorides. LÄS MER

  5. 14. Metabolism-dependent activation of food and environmental mutagens in endothelial cells

    Författare :Anita Annas; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical biosciences; Farmaceutisk biovetenskap; Biopharmacy; Biofarmaci; Toxicology; toxikologi;

    Sammanfattning : The endothelial cells of blood vessels have been proposed as a target for toxic effects ofxenobiotics in the cardiovascular system. In the present studies, induction of cytochromeP450 1A (CYP1A) enzymes and metabolic activation of food and environmentalmutagens were examined in endothelial cells of rodents, birds, and humans.

  7. 15. A study on the vascular effects of prostaglandin F2α[ and latanaprost in the eye with special reference to the surface hyperaemia after topical administration

    Författare :Maria Astin; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical biosciences; Prostaglandin F2a; Prostaglandin F2a-isopropyl ester; latanoprost; latanoprost acid; ocularhyperaemia; blood flow; sensory nerves; veins; arteries; nitric oxide; substance P; CGRP; Farmaceutisk biovetenskap; Biopharmacy; Biofarmaci; Pharmacognosy; farmakognosi;

    Sammanfattning : The ocular hypotensive effect of topically applied prostaglandins is usually accompanied byconjunctival hyperaemia and irritation. The purpose of the present study was to investigate thepharmacological mechanism of the ocular surface hyperaemia induced by topically appliedprostaglandins, particularly prostaglandin F2α (PGF2α) and its synthetic analogue latanoprost, aselective FP prostanoid receptor agonist.
