          机体各组织的正常发育至关重要,而其异常活化会导致乳腺癌、肝癌、胰腺癌、肺癌等多种恶性肿瘤的发生与发展,这使得Hh途径
          成为抗肿瘤药物研发的理想靶点。目前,Hh信号通路抑制剂主要作用靶点包括Hh配体、受体Smoothened(Smo)及转录因子Gli。
          其中,依赖于Hh配体途径的化合物因无法作用于非经典Hh信号通路仍停留在实验室研究层面;Smo蛋白的特殊结构使之能与药
          物高效、选择性地结合,是一个强大而有效的药物作用靶点,因而Smo选择性抑制剂一直是相关研究的活跃领域,且已有多个Smo
          抑制剂进入临床使用或试验阶段;Gli能调控多个致癌基因,促进细胞异常增殖而导致肿瘤的发生,还可对Hh信号通路进行反馈
          抑制,因此研发能够抑制Gli活性的药物具有广阔前景。在今后的研发中,可考虑设计作用于多种通路抑制剂,以避免耐药性和其

          ABSTRACT    Hedgehog (Hh)  signaling  pathway  plays  an  important  regulatory  role  in  the  process  of  cell  proliferation,
          differentiation and tissue formation. Proper intensity and action time of Hh signal are crucial for the normal development of various
          tissues  of  the  body,  and  its  abnormal  activation  will  lead  to  the  occurrence  and  development  of  most  malignant  tumors,  including
          breast  cancer,  liver  cancer,  pancreatic  cancer,  and  lung  cancer,  which  makes  Hh  signaling  pathway  an  ideal  target  for  anti-tumor
          drug  research  and  development.  At  present,  the  main  targets  of  Hh  signaling  pathway  inhibitors  include  Hh  ligand,  receptor
          Smoothened (Smo) and transcription factor Gli. Among them, the compounds that depend on the Hh ligand pathway still remain at
          the  stage  of  laboratory  research  because  they  cannot  act  on  the  non-classical  Hh  signaling  pathway.  The  special  structure  of  Smo
          protein enables it to combine with drugs efficiently and selectively, which is a powerful and effective drug target. Therefore, Smo
          selective  inhibitors  have  been  an  active  field  of  related  research,  and  many  Smo  inhibitors  have  entered  the  clinical  use  or  trial
          stage.  Gli  can  regulate  multiple  carcinogenic  genes,  promote  abnormal  cell  proliferation  and  lead  to  tumor,  and  can  also  cause
          feedback  inhibition  to  Hh  signaling  pathway.  Therefore,  the  development  of  drugs  that  can  inhibit  the  activity  of  Gli  has  broad
          prospects.  In  the  future,  a  combination  of  multiple  pathway  inhibitors  can  be  designed  to  avoid  drug  resistance  and  other  side
          effects.
