  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.

  2-（烷基氨基）烟酸及其类似物。强大的血管紧张素II拮抗剂。

  摘要：

  人们发现，通过-CH2-NR'-连接（1）连接到联苯四唑的一系列吡啶和其他六元环杂环是有效的血管紧张素II拮抗剂。在嘧啶羧酸系列中（W = CR，X = N，Y = CH，Z = COOH），环外氮上带有烷基（R'）的化合物比带有烷基（R）的化合物更有效在杂环上。相应的吡啶，哒嗪，吡嗪和1,2,4-三嗪羧酸也显示出有效的体外血管紧张素II拮抗作用。吡啶（W，X，Y = CH，Z = COOH，R'= n-C3H7）具有很强的体外活性（pA2 = 10.10，兔主动脉，Ki = 0.61 nM，大鼠肝脏中的受体结合）以及出色的口服降压活性和生物利用度。

  Protein tyrosine phosphatases (PTPases) such as PTP1B can play a role in regulating a wide variety of cellular responses such as insulin signaling. Substituted bicyclic fused-thiophene compounds can inhibit PTP1B and thereby induce greater insulin sensitivity. Accordingly, PTP1B inhibition can provide an alternate treatment for PTPase-mediated disorders such as diabetes.

  蛋白质酪氨酸磷酸酶（PTPases），如PTP1B，在调节广泛的细胞反应，如胰岛素信号传导中发挥作用。取代的并环融合噻吩化合物可以抑制PTP1B，从而增加胰岛素敏感性。因此，PTP1B的抑制可以提供一种治疗PTPase介导的疾病，如糖尿病的替代方法。
