  2. 1. Computational and Experimental Models for the Prediction of Intestinal Drug Solubility and Absorption

    Author : Christel A. S. Bergström; Per Artursson; Han van de Waterbeemd; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutics; aqueous drug solubility; melting point; intestinal drug permeability; pH-dependent solubility; multivariate data analysis; molecular descriptors; molecular surface area; in silico modeling; drug absorption; Galenisk farmaci; Pharmaceutics; Galenisk farmaci;

    Abstract : New effective experimental techniques in medicinal chemistry and pharmacology have resulted in a vast increase in the number of pharmacologically interesting compounds. However, the number of new drugs undergoing clinical trial has not augmented at the same pace, which in part has been attributed to poor absorption of the compounds. READ MORE

  4. 2. Effects of Rho kinase, prostacyclin and L-arginine on microvascular permeability and perfusion

    Author : Cornelia Lundblad; Institutionen för immunteknologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Fysiologi; Physiology; skeletal muscle; Rho kinase; prostacyclin; permeability; NO; experimental brain trauma; brain edema; brain contusion; microcirculation; cerebral perfusion;

    Abstract : This thesis presents some effects of Rho kinase, prostacyclin (PGI2) and nitric oxide (NO) in relation to trauma and inflammation by evaluating their effects on microvascular perfusion and permeability in mouse brain and in cat skeletal muscle. PGI2 and NO are endogenous vasoactive substances produced by the endothelium. READ MORE

  6. 4. Probing intestinal permeability in man using different-sized, low-molecular-weight polyethyleneglycols and mathematical modelling

    Author : Tommy Sundqvist; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Selective intestinal permeability as reflected by the urinary recovery of low-molecular-weight polyethylene glycols (PEG 400) of dlfferentsizes after oral administration was characterized with a mathematical filter-function. There was relative loss of both large and small PEG molecules on their way from the intestine to the urine. READ MORE

  7. 5. Experimental and theoretical predictions of intestinal drug absorption

    Author : Katrin Palm; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacy; FARMACI; PHARMACY; FARMACI; galenisk farmaci; Pharmaceutics;

    Abstract : The subject of this thesis is the development of better experimental and computational predictions of the intestinal absorption properties of new drug candidates. In the last decade the drug discovery process has produced an increasing number of new drug candidates by the use of high throughput screening techniques. READ MORE
