  Novel, Potent, and Selective Phosphodiesterase 5 Inhibitors:  Synthesis and Biological Activities of a Series of 4-Aryl-1-isoquinolinone Derivatives

  摘要：

  A novel class of potent and selective phosphodiesterase 5 (PDE5) inhibitors, 4-aryl-1-iso-quinolinone derivatives, which have been designed by the comparison of the structure of cGMP and a previously reported 1-arylnaphthalene lignan, was disclosed. Among these compounds, methyl 2-(4-aminophenyl)-1,2-dihydro-1-oxo-7-(2-pyridinylmethoxy)-4-(3,4,5-trimethoxyphenyl)- 3-isoquinoline carboxylate dihydrochloride (36a) exhibited potent PDE5 inhibitory activity (IC50 = 1.0 nM) with high isozyme selectivities (IC50 ratio: PDE1/PDE5 = 1300, PDE2/PDE5 > 10 000, PDE3/PDE5 > 10 000, PDE4/PDE5 = 4700, PDE6/PDE5 = 28). Compound 36a also showed the most potent relaxant effect on isolated rabbit corpus cavernosum (EC30 = 7.9 nM). Compound 63 (T-1032), the sulfate form of 36a, was selected for further biological and pharmacological evaluation of erectile dysfunction.

  (EN) An isoquinolinone derivative of formula (I) wherein Ring A and Ring B are substituted or unsubstituted benzene, R1 is (1) H, (2) substituted or unsubstituted lower alkyl, (3) substituted or unsubstituted cyclo-lower alkyl, (4) substituted or unsubstituted aryl, (5) substituted or unsubstituted heterocycle, or (6) amino optionally having one or two substitutents, R2 is -COOR3 or -CON(R4)(R5), R3 is H or ester residue, and -N(R4)(R5) is substituted or unsubstituted nitrogen-containing aliphatic heterocycle or substituted or unsubstituted amino, provided that when R1 is H or substituted or unsubstituted lower alkyl, then at least one of Ring A and Ring B is benzene being substituted by two or more lower alkoxy, or a pharmaceutically acceptable salt thereof, these compounds showing cGMP-specific PDE inhibitory activity, especially, selective phosphodiesterase V (PDEV) inhibitory activity, and hence, being useful for the prophylaxis or treatment of various diseases such as chronic heart failure, angina, pulmonary hypertension, erectile dysfunction, etc.(FR) Dérivés d'isoquinolinone de formule (I) dans laquelle le noyau A et le noyau B sont benzène substitué ou non substitué, R1 est (1) H, (2) alkyle inférieur substitué ou non substitué, (3) cycloalkyle inférieur substitué ou non substitué, (4) aryle substitué ou non substitué, (5) hétérocycle substitué ou non substitué ou (6) amino ayant éventuellement un ou deux substituants, R2 est -COOR3 ou -CON(R4)(R5), R3 est H ou un reste ester et -N(R4)(R5) est un hétérocycle aliphatique contenant azote substitué ou non substitué ou amino substitué ou non substitué, à condition que lorsque R1 est H ou alkyle inférieur substitué ou non substitué, au moins l'un des noyaux A et B soit benzène substitué par deux alcoxy inférieur ou plus, ou sel pharmaceutiquement acceptable desdits composés. Lesdits composés présentent une activité d'inhibition de la photodiestérase spécifique de cGMP, en particulier une activité sélective d'inhibition de la phosphodiestérase V, et sont donc utiles pour la prophylaxie ou le traitement de diverses maladies telles que l'insuffisance cardiaque chronique, l'angine de poitrine, l'hypertension pulmonaire, la dysérection, etc.

  (I)式中的异喹啉酮衍生物，其中环A和环B是取代或未取代的苯，R1为(1)H，(2)取代或未取代的低烷基，(3)取代或未取代的环低烷基，(4)取代或未取代的芳基，(5)取代或未取代的杂环，或(6)氨基，可选地具有一个或两个取代基，R2为-COOR3或-CON(R4)(R5)，R3为H或酯残基，而-N(R4)(R5)是取代或未取代的含氮脂肪杂环或取代或未取代的氨基，但当R1为H或取代或未取代的低烷基时，至少有一个环A和环B为取代了两个或更多的低烷氧基的苯，或其药学上可接受的盐。这些化合物显示出cGMP特异性PDE抑制活性，特别是选择性磷酸二酯酶V（PDEV）抑制活性，因此，它们对于预防或治疗各种疾病如慢性心力衰竭、心绞痛、肺动脉高压、勃起功能障碍等是有用的。
