          摘   要  目的  分析、鉴定匹妥布替尼(PTN)在大鼠体内的代谢产物,并探讨其在大鼠体内的可能代谢途径。方法  6只大鼠按照
          10 mg/kg灌胃PTN混悬液,收集大鼠给药前30 min以及给药后0.25、0.5、1、2、4、6、8、12、24 h的血液和给药前12 h及给药后24 h
          的尿液和粪便。采用UHPLC-Orbitrap Exploris 240系统联合Compound Discoverer 3.0和Xcalibur 2.0数据分析软件对PTN在大鼠
          血浆、尿液和粪便中的代谢产物进行结构鉴定与代谢途径分析。结果  在大鼠生物样本中共鉴定出29种PTN代谢产物,在血浆、
          尿液和粪便样本中分别鉴定出17、19和22种代谢产物。PTN的代谢途径主要包括氧化、硫酸化、葡萄糖醛酸化等,且其代谢产物
          多为2种及以上不同代谢形式的组合产物。其中,涉及Ⅰ相代谢反应的产物共计26个(氧化14个、还原/脱氢9个、脱甲基8个、水
          解5个),涉及Ⅱ相代谢反应的产物共计20个(硫酸化14个、葡萄糖醛酸化8个)。结论  PTN在大鼠粪便样本中代谢产物种类较
          多,主要代谢途径为氧化、硫酸化、葡萄糖醛酸化等。

          ABSTRACT    OBJECTIVE  To  analyze  and  identify  the  metabolites  of  pirtobrutinib (PTN)  in  rats,  and  clarify  the  possible
          metabolic  pathways  of  PTN  in  rats.  METHODS  Six  rats  were  intragastrically  administered  with  10  mg/kg  PTN  suspension.  Blood
          samples  were  collected  from  the  rats  30  minutes  before  administration  and  at  0.25,  0.5,  1,  2,  4,  6,  8,  12,  24  hours  after
          administration.  Urine  and  feces  samples  were  collected  12  hours  before  administration  and  24  hours  after  administration.  UHPLC-
          Orbitrap  Exploris  240  system  combined  with  Compound  Discoverer  3.0  and  Xcalibur  2.0  software  were  adopted  for  structural
          identification  and  metabolic  pathway  analysis  of  PTN  metabolites  in  rat  plasma,  urine,  and  feces.  RESULTS  A  total  of  29  PTN
          metabolites were identified, including 17, 19 and 22 metabolites in plasma, urine and feces, respectively. The metabolic pathways
          of  PTN  mainly  included  oxidation,  sulfation,  glucuronidation,  etc.,  and  its  metabolites  were  mostly  combination  products  of  two
          or  more  different  metabolic  forms.  In  detail,  a  total  of  26  metabolites  were  associated  with  phase  Ⅰ  metabolic  reactions (14
          oxidation  metabolites,  9  reduction/dehydrogenation  metabolites,  8  demethylation  metabolites,  and  5  hydrolysis  metabolites).
          Meanwhile,  a  total  of  20  products  were  involved  in  phase  Ⅱ  metabolites (14  sulfation  metabolites  and  8  glucuronic  acid  binding
          metabolites).  CONCLUSIONS  PTN  exhibits  a  diverse  range  of  metabolites  in  rat  fecal  samples,  with  the  primary  metabolic
          pathways being oxidation, sulfation, glucuronidation, and others.
