摘要: |
目的 寻找新型的非ATP竞争糖原合成酶激酶-3β(GSK-3β)抑制剂。方法 针对GSK-3β的非ATP结合的底物作用位点为靶点,采用Autodock程序对类药性小分子库Maybridge进行虚拟筛选寻找新型GSK-3β抑制剂。采用克脑文格尔反应,环合及N-烷基化反应制备目标化合物。采用体外酶抑制活性测试目标化合物的活性。结果 化合物2-(2-呋喃基)-5-苄基-2,3-二氢苯并[b][1,4]硫氮杂-4(5H)-酮对GSK-3β具有中等抑制活性(IC50 47.69±2.38 μmol·L-1)。结论 活性化合物的结构与目前报道的其他GSK-3β抑制剂不同,可望作为新的先导化合物,值得进一步研究。 |

Abstract: |
OBJECTIVE To discover novel non-ATP competitive glycogen synthase kinase-3β(GSK-3β) inhibitors. METHODS A virtual screening was conducted by Autodock program, which docked the small drug-like molecules of Maybridge library at the non-ATP binding site of GSK-3β. The target compounds had been designed based on the virtual screening result and successfully synthesized through Knoevenagel reaction, cyclization and N-alkylation. The inhibition to GSK-3β was tested by in vitro enzamic test. RESULTS 5-benzyl-2-(furan-2-yl)-2,3-dihydrobenzo[b][1,4] thiazepin-4(5H)-one showed moderate inhibition to GSK-3β in vitro (IC50 47.69±2.38 μmol·L-1). CONCLUSION The discovered new active compound is structurally different to other inhibitors of GSK-3β and worthy of further study as a novel lead compound. |
