          摘  要  目的  分析 2 型糖尿病新靶点口服药专利概况,为国内新型糖尿病治疗药物的研发方向和专利布局等提供参考。方法
          以HimmPat数据库中全球专利数据为基础,从专利申请量及授权量、发展趋势、地域分布、主要申请人等多个角度,对葡萄糖激酶
          激活剂(GKA)、蛋白酪氨酸磷酸酶1B抑制剂(PTP-1B-IN)、11β-羟基类固醇脱氢酶1抑制剂(11β-HSD1-IN)3类2型糖尿病新靶点
          口服药相关专利进行统计分析。结果与结论  共检索得到 GKA 类专利 1 649 件,PTP-1B-IN 类专利 709 件,11β-HSD1-IN 类专利
          592件。全球主要申请主体为各大药企,其掌握了药物化合物的核心专利;其中GKA类药物的研究更成熟,专利申请量更大,企业
          布局更全面。国内企业、高校和科研院所在PTP-1B-IN领域具有一定的研究优势。国内企业和研究机构可以发挥传统中药资源
          优势,提升研究实力,可考虑从核心技术挖掘、工艺路线探索、专利布局、产学研合作、构建专利池等方面提高技术竞争力。

          ABSTRACT   OBJECTIVE To analyze the patents of new target oral drugs for type 2 diabetes mellitus (T2DM), and to provide
          references  for  the  research  and  development  direction  and  patent  layout  of  new  domestic  diabetes  drugs.  METHODS  Based  on
          global  patent  data  in  the  HimmPat  database,  from  multiple  perspectives  such  as  the  number  of  patent  applications  and
          authorization,  development  trend,  regional  distribution  and  main  applicants,  statistics  and  analysis  were  performed  for  the  patents
          related  to  3  types  of  new  target  oral  drugs  for  T2DM,  such  as  glucokinase  activator (GKA),  protein  tyrosine  phosphatase  1B
          inhibitor (PTP-1B-IN),  and  11β-hydroxysteroid  dehydrogenase  1  inhibitor (11β-HSD1-IN).  RESULTS  &  CONCLUSIONS  A
          total of 1 649 patents of GKA, 709 patents of PTP-1B-IN, 592 patents of 11β-HSD1-IN were obtained, the main applicants were
          well-known pharmaceutical companies, which possessed the core patents of pharmaceutical compounds. The research on GKA drugs
          was  more  mature,  with  a  larger  number  of  patent  applications  and  a  more  comprehensive  enterprise  layout.  Domestic  enterprises,
          universities  and  research  institutions  had  advantages  in  the  field  of  PTP-1B-IN.  Domestic  enterprises  and  research  institutions  can
          leverage  the  advantages  of  traditional  Chinese  medicine  and  resources  to  enhance  their  research  capabilities  and  improve
          technological  competitiveness  through  core  technology  exploration,  the  exploration  of  process  route,  patent  layout,  industry-
          university-research cooperation and the establishment of patent pool.
