1H-Pyrazolo[4,3-d]pyrimidines were previously disclosed as a potent second generation class of phosphodiesterase 5 (PDE5) inhibitors. This work explores the advancement of more selective and potent PDE5 inhibitors resulting from the substitution of 2-(2,2,2-trifluoroethoxy)ethyl at the 1 position in the so-called alkoxy pocket.
1 H-吡唑并[4,3- d ]嘧啶是先前公开的有效的第二代磷酸二酯酶5(PDE5)抑制剂。这项工作探索了更选择性和更有效的PDE5抑制剂的进展,该抑制剂是由于在所谓的烷氧基口袋中的1位取代了2-(2,2,2-三氟乙氧基)乙基而产生的。
