“…Compound 8 , a recently disclosed human PDE10 inhibitor, displayed 55% inhibition at 100 μM. Recognizing the extensive precedence in human PDE4 inhibitors, including a number of compounds that have entered clinical trials, we made this family of inhibitors our primary focus.…”

“…The X-ray data will certainly assist in our attempts to understand the basis for the enhancements in potency shown by PDE4 inhibitors such as cilomilast ( 16) 44 and roflumilast (17), 45 which are in very advanced clinical evaluation for asthma and chronic obstructive pulmonary disease and are clearly related to rolipram with respect to the catechol ether moiety. 46 In addition, extended structures such as N-aryl analogues (e.g., 18) have been reported that exhibit enhanced potency and stereoselectivity relative to rolipram. 47 Whether these extended substituents target specific binding regions at the outer edge of the binding pocket and are analogous to those occupied by PDE5 inhibitors requires experimental clarification.…”

“…11 isoformas de PDE's (PDE1-PDE11) 32,33 , amplamente distribuídas em diferentes tecidos ou célu-las como coração, cérebro, neutrófilos, linfócitos-T, macrófagos, eosinófilos, plaquetas, entre outros, classificadas em função do nucleotídeo cíclico que elegem como substrato específico ou preferencial 31 . O efeito de um inibidor seletivo de PDE's promove acúmulo de cAMP ou cGMP em determinado tecido, modulando, por exem- plo, canais iônicos celulares e alterando o estado de ativação destas células, resultando, por exemplo, no relaxamento da musculatura lisa ou na redução da atividade de células inflamatogênicas 34 . A isoforma PDE4, específica para cAMP, por exemplo, pode apresentar, ainda, sub-tipos (PDE4A-D) 35 e é aquela predominantemente envolvida na resposta inflamatória, sendo inibidores seletivos desta isoforma fármacos como o rolipram (19), capazes de reduzirem a produção de citocinas flogísticas e atenuarem a evolução da resposta inflamatória do processo asmático 36,37 .…”
