2 (PDE2) has been regarded as a novel target for the treatment of Alzheimer’s disease (AD). In this study, we obtained (R)-LZ77 as a hit compound with moderate PDE2 inhibitory activity (IC50 = 261.3 nM) using a high-throughput virtual screening method based on molecular dynamics. Then, we designed and synthesized 28 dihydropyranopyrazole derivatives as PDE2 inhibitors. Among them, compound (+)-11h was
磷酸二酯酶2(PDE2)已被视为治疗阿尔茨海默氏病(AD)的新型靶标。在这项研究中,我们获得了(- [R )- LZ77作为中度PDE2抑制活性(IC命中化合物50使用基于分子动力学高通量虚拟筛选方法= 261.3纳米)。然后,我们设计并合成了28种二氢吡喃并吡唑衍生物作为PDE2抑制剂。其中,化合物(+)- 11h是最有效的PDE2抑制剂,IC 50值为41.5 nM。PDE2-(+)- 11h的分子对接揭示了该化合物的4-(三氟甲基)苄基)氧基侧链进入H型口袋并与L770 / L809 / F862形成强疏水相互作用,从而提高了抑制活性。以上结果可为进一步高效优化PDE2抑制剂的结构提供见识,并可为其在AD治疗中的应用奠定基础。
