          摘  要  目的  研究小分子抑制剂SYHA1809在比格犬体内的药动学。方法  采用液相色谱-串联质谱(LC-MS/MS)法进行测定。
          将比格犬随机分为单次静脉给药组(3.75 mg/kg)、单次低剂量灌胃组(3.75 mg/kg)、单次中剂量灌胃组(7.5 mg/kg)、单次高剂量灌
          胃组(15 mg/kg)和多次灌胃组(7.5 mg/kg,每天 1 次,连续 7 d),每组 6 只,雌雄各半。各组比格犬按照设定的时间点收集血浆样
          品,经预处理后进行LC-MS/MS定量分析,获得的数据采用Phoenix WinNonlin 8.0软件计算药动学参数。结果  SYHA1809静脉注
          射给药后,在比格犬体内的 CL 为(2.70±0.48) mL/(min·kg),稳态分布体积为 0.757 L/kg,t1/2为(3.35±1.36) h;单次灌胃给予低、
          中、高剂量的SYHA1809后,其在比格犬体内的平均tmax为(0.53±0.02) h,血药浓度随给药剂量的增加而升高;单次灌胃给予3.75
          mg/kg的SYHA1809后,绝对生物利用度为83.5%;在3.75~15 mg/kg剂量范围内,SYHA1809的cmax和AUC增加与剂量呈正相关;
          SYHA1809 连续以 7.5 mg/kg 灌胃 7 d 后,与同剂量单次灌胃给药后的药动学参数相当,差异无统计学意义(P>0.05)。结论
          SYHA1809在比格犬体内吸收迅速,血药浓度呈剂量依赖性,生物利用度高,多次灌胃给药后无明显蓄积,药动学行为良好。

          ABSTRACT   OBJECTIVE  To  study  the  pharmacokinetics  of  small  molecule  inhibitor  SYHA1809  in  Beagle  dogs.  METHODS
          LC-MS/MS  method  was  adopted.  Beagle  dogs  were  randomly  divided  into  single  intravenous  administration  group (3.75  mg/kg),
          single low-dose intragastric administration group (3.75 mg/kg), single medium-dose intragastric administration group (7.5 mg/kg),
          single  high-dose  intragastric  administration  group (15  mg/kg)  and  multiple  intragastric  administration  group (7.5  mg/kg,  once  a
          day,  for  7  consecutive  days),  with  6  dogs  in  each  group,  half  male  and  half  female.  The  plasma  samples  of  Beagle  dogs  were
          collected  in  each  group  according  to  the  set  time  point,  and  underwent  LC-MS/MS  quantitative  analysis  after  preprocessing.  The
          pharmacokinetic  parameters  were  calculated  by  using  Phoenix  WinNonlin  8.0  software  using  obtained  data.  RESULTS  After
          intravenous  injection,  CL  of  SYHA1809  in  Beagle  dogs  was (2.70±0.48)  mL/(min·kg),  steady-state  distribution  volume  was
          0.757  L/kg,  and  t1/2  was (3.35±1.36)  h;  after  single  intragastric  administration  of  low-dose,  medium-dose  and  high-dose  of
          SYHA1809,  average  tmax  was (0.53±0.02)  h,  and  the  blood  drug  concentration  increased  with  the  increase  of  dose;  after  single
          intragastric  administration  of  3.75  mg/kg  SYHA1809,  the  absolute  bioavailability  was  83.5%;  within  the  dose  range  of  3.75-15
          mg/kg,  the  increase  in  cmax and AUC  of  SYHA1809  was  positively  correlated  with  the  dose;  after  intragastric  administration  of  7.5
          mg/kg  SYHA1809  for  7  consecutive  days,  the  pharmacokinetic  parameters  of  SYHA1809  were  comparable  to  those  of  a  single
          intragastric administration of the same dose, with no statistically significant difference (P>0.05). CONCLUSIONS SYHA1809 is
          absorbed  rapidly  in  Beagle  dogs,  shows  the  dose-dependent  blood  concentration,  high  bioavailability,  no  obvious  accumulation
          after multiple intragastric administration, and good pharmacokinetic behavior.
