explore the biology of PDE2A inhibition, we sought to identify potent PDE2A inhibitors with improved brain penetration as compared to current literature compounds. Applying estimated human dose calculations while simultaneously leveraging synthetically enabled chemistry and structure-based drug design has resulted in a highly potent, selective, brain penetrant compound 71 (PF-05085727) that effects in
据报道,磷酸二酯酶2A(PDE2A)抑制剂在临床前认知模型中具有体内活性。为了更全面地探索PDE2A抑制的生物学特性,我们寻求鉴定与当前文献化合物相比具有增强的脑渗透性的有效PDE2A抑制剂。在应用估计的人体剂量计算的同时,利用合成化学和基于结构的药物设计,可以产生出高效,选择性,脑渗透性化合物71(PF-05085727),其对体内生化变化的影响与对PDE2A的抑制以及NMDA拮抗剂对啮齿类动物的影响的行为和电生理逆转相称。此数据支持PDE2A抑制剂增强NMDA信号的能力,以及它们对临床认知指征的进一步发展。
