  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.

  公开号：US20010044434A1

  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.

  本发明涉及用于治疗对体内睾酮水平升高有响应的情况的方法和药物组合物，以及使用雌激素激动剂/拮抗剂制造治疗对体内睾酮水平升高有响应的情况的药物。该组合物由雌激素激动剂/拮抗剂和药学上可接受的载体、载体或稀释剂组成。这些组合物有效地治疗男性性功能障碍和女性主体的胆怯，包括绝经后的妇女，并有效地增加女性主体的性欲，包括绝经后的妇女。在男性性功能障碍的情况下，该组合物还可以包括一种升高环鸟苷酸3′，5′-单磷酸（cGMP）的化合物。此外，该组合物对其他由睾酮缺乏引起的或可以通过提高体内睾酮水平改善的情况也有效。本发明的方法包括治疗对升高睾酮水平有响应的情况，例如治疗男性性功能障碍和女性主体的胆怯，包括绝经后的妇女，并增加女性主体的性欲，包括绝经后的妇女。该治疗方法在显著降低睾酮管理相关的不良反应的同时，也是有效的。
