target for many diseases, however, up to now, there is no AC2-selective agonist reported. In this research, docking-based virtual screening with the combination of cell-based biological assays have been performed for discovering novel potent and selective AC2 agonists. Virtual screening disclosed a novel hit compound 8 as an AC2 agonist with EC50 value of 8.10 μM on recombinant human hAC2 + HEK293 cells
腺苷酸环化酶(AC)在三磷酸腺苷(ATP)转化为第二信使环单磷酸腺苷(cAMP)的过程中起关键作用。研究表明2型腺苷酸环化酶(AC2)是许多疾病的潜在药物靶标,但是,到目前为止,尚无AC2选择性激动剂的报道。在这项研究中,已经进行了基于对接的虚拟筛选与基于细胞的生物学检测相结合,以发现新型有效的和选择性的AC2激动剂。虚拟筛选揭示了一种新型的命中化合物8,作为AC2激动剂,在重组人hAC2 + HEK293细胞上的EC50值为8.10μM。在重组AC2细胞上进一步研究了基于化合物8衍生物的SAR(结构活性关系),发现化合物73是最具活性的激动剂,EC50为90 nM,它比报道的激动剂福斯高林强160倍,并且可以选择性激活AC2以抑制白介素6的表达。新型AC2选择性激动剂的发现将为研究AC2的生理功能提供一种新颖的化学探针。
