Journal ArticleDOI
Can light absorption and photostability data be used to assess the photosafety risks in patients for a new drug molecule
TL;DR: The current study was undertaken to determine the level of light absorption by measuring the molar extinction coefficients (MEC) of a wide range of compounds reported in the literature to have known photosafety issues in humans and the results have shown that all compounds tested have absorbance intensities significantly above an MEC threshold of 1000 L mol (-1)cm(-1) and also display a widerange of photoinstability.
Journal ArticleDOI
Characterisation of human saliva as a platform for oral dissolution medium development.
TL;DR: The pH, buffer capacity, surface tension, viscosity and flow rate of both unstimulated (US) and stimulated (SS) human saliva were investigated to provide a platform of reference for future dissolution studies using simulated salivary fluids.
Journal ArticleDOI
Selective Urokinase-Type Plasminogen Activator Inhibitors. 4. 1-(7-Sulfonamidoisoquinolinyl)guanidines†
Paul V. Fish,Barber Christopher Gordon,David G. Brown,Richard P. Butt,Michael G. Collis,Dickinson Roger Peter,Brian Henry,Valerie A. Horne,John P. Huggins,Elizabeth King,Margaret O'Gara,Dawn Mccleverty,Fraser Stuart Mcintosh,Christopher Phillips,Rob Webster +14 more
TL;DR: Investigation of this template has revealed that incorporation of a 7-sulfonamide group furnishes a new series of potent and highly selective uPA inhibitors, which were selected as a candidate for further preclinical evaluation for the treatment of chronic dermal ulcers.
Journal ArticleDOI
Resolution of P-glycoprotein and non-P-glycoprotein effects on drug permeability using intestinal tissues from mdr1a (-/-) mice.
RH Stephens,Catherine A. O'Neill,Joanne Bennett,Michael John Humphrey,Brian Henry,Malcolm Rowland,Geoffrey Warhurst +6 more
TL;DR: Tissues from mdr1a (−/−) mice provide a novel approach for investigating the influence of PGP ablation on intestinal permeability and for resolving PGP and non‐PGP mechanisms that modulate drug permeability.
Journal ArticleDOI
Evaluation of the Intelisite capsule to deliver theophylline and frusemide tablets to the small intestine and colon.
Nicola Clear,Ashley Milton,Michael John Humphrey,Brian Henry,Maria Wulff,Don Nichols,R.J. Anziano,Ian R. Wilding +7 more
TL;DR: The probe drugs were successfully delivered in particulate form from the Intelisite capsule in the small intestine and produced expected pharmacokinetic profiles, however drug release in the colon was incomplete and variable possibly due to: low water content, poor mixing, and a high loading dose.
