  A Novel Series of Potent and Selective PDE5 Inhibitors with Potential for High and Dose-Independent Oral Bioavailability

  摘要：

  Sildenafil ( 5-[ 2-ethoxy-5-(4-methyl-1-piperazinylsulfonyl) phenyl]-1-methyl-3-n-propyl-1,6-dihydro-7H-pyrazolo[ 4,3-d] pyrimidin-7-one), a potent and selective phosphodiesterase type 5 ( PDE5) inhibitor, provided the first oral treatment for male erectile dysfunction. The objective of the work reported in this paper was to combine high levels of PDE5 potency and selectivity with high and dose-independent oral bioavailability, to minimize the impact on the C-max of any interactions with coadministered drugs in the clinic. This goal was achieved through identification of a lower clearance series with a high absorption profile, by replacing the 5'-piperazine sulfonamide in the sildenafil template with a 5'-methyl ketone. This novel series provided compounds with low metabolism in human hepatocytes, excellent caco-2 flux, and the potential for good aqueous solubility. The in vivo oral and iv pharmacokinetic profiles of example compounds confirmed the high oral bioavailability predicted from these in vitro screens. 5-( 5-Acetyl-2-butoxy-3-pyridinyl)-3-ethyl-2-( 1-ethyl-3-azetidinyl)-2,6-dihydro-7H-pyrazolo[ 4,3-d] pyrimidin-7-one ( 2) was selected for progression into the clinic.

  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 &agr;-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 &agr;-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 &agr;-melanocyte stimulating hormone to melanocortin receptors.

  公开（公告）日：2001-11-22

  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.
