- The discovery of UK-369003, a novel PDE5 inhibitor with the potential for oral bioavailability and dose-proportional pharmacokinetics
-
This paper describes our recent efforts to design and synthesise potent and selective PDE5 inhibitors and the use of in vitro predictors of clearance, absorption and permeability to maximise the potential for dose-proportional pharmacokinetics and good oral bioavailability in man. Optimisation of the preclinical profile resulted in the identification of UK-369003 (19a) and its nomination as a clinical candidate. The clinical pharmacokinetic and safety profile has enabled us to progress the compound to test its efficacy in patients with lower urinary tract symptoms (LUTS) associated with benign prostatic hyperplasia (BPH) and a paper describing its efficacy has recently been published.2,3.

- Treatments for female sexual dysfunction and methods for identifying compounds useful for treating female sexual dysfunction
-
The present invention provides a method of treating female sexual dysfunction, the method comprising the step of administering to a patent, having or at risk of having one or more of the disorders or conditions associated with female sexual dysfunction, a therapeutically effective amount of a compound that attenuates the binding of agouti-related protein to melanocortin receptors, but does not attenuate the binding of alpha-melanocyte stimulating hormone to melanocortin receptors. The present invention also provides a method of identifying a compound that is useful for the treatment or prevention of female sexual dysfunction, the method comprising the steps of: 1) determining if a compound affects the binding of agouti-related protein to melanocortin receptors; 2) determining if a compound affects the binding of alpha-melanocyte stimulating hormone to melanocortin receptors; and 3) selecting a compound that attenuates the binding of agouti-related protein to melanocortin receptors, but does not affect the binding of alpha-melanocyte stimulating hormone to melanocortin receptors.

- Compositions and methods of treatment for conditions responsive to testosterone elevation
-
This invention relates to methods and pharmaceutical compositions useful in the treatment of conditions that are responsive to the elevation of testosterone levels in the body and the use of estrogen agonists/antagonists for the manufacture of medicaments for the treatment of conditions that are responsive to the elevation of testosterone levels in the body. The compositions are comprised of an estrogen agonist/antagonist and a pharmaceutically acceptable vehicle, carrier or diluent. These compositions are effective in treating male subject sexual dysfunction and timidity in female subjects including post-menopausal women and are effective in increasing libido in female subjects including post-menopausal women. In the case of male subject sexual dysfunction, the compositions may also include a compound which is an elevator of cyclic guanosine 3′,5′-monophosphate (cGMP). Additionally, the compositions are effective in other conditions whose etiology is a result of testosterone deficiency or which can be ameliorated by increasing testosterone levels within the body. Methods of the invention include the treatment of conditions that are responsive to elevation of testosterone levels such as treating male subject sexual dysfunction and timidity in female subjects including post-menopausal women and the increase of libido of female subjects including post-menopausal women. The methods of treatment are effective while substantially reducing the concomitant liability of adverse effects associated with testosterone administration.
