          摘  要  目的  制备黄体酮-2-氯-4-硝基苯胺(CNA)共晶以提高黄体酮的水溶性,并初步评价其体内安全性。方法  选用黄体酮为
          共晶主体,CNA为共晶配体,采用溶剂挥发法制备黄体酮-CNA共晶。通过单晶X射线衍射、粉末X射线衍射、差示扫描量热、红
          外光谱等技术对共晶进行表征,并对比共晶与黄体酮原料药、黄体酮与CNA物理混合物之间的溶出度差异。将48只雌性KM小
          鼠随机分为正常组(含0.1%二甲基亚砜的磷酸盐缓冲液)、黄体酮组(16 mg/kg)、CNA组(9 mg/kg)和黄体酮-CNA共晶低、中、高
          剂量组(6、12.5、25 mg/kg),每组8只;肌内注射相应药物/溶剂,每天给药1次,连续14 d。通过测定/观察小鼠体质量、脏器指数、组
          织形态、血常规及肝肾功能指标变化来初步评价共晶的安全性。结果  单晶X射线衍射实验结果中新晶型结构的出现、粉末X射
          线衍射图谱里新特征峰的出现、差示扫描量热检测结果中熔点的改变以及红外光谱图中3 500 ~2 750、1 700~1 250 cm 范围内
                                                                                                      -1
          特征峰位置的改变,均表明黄体酮-CNA共晶制备成功,且所制共晶的溶出速率比黄体酮原料药提高了1倍以上。体内安全性实
          验结果显示,各组小鼠死亡率均为零。与正常组比较,黄体酮组及黄体酮-CNA 共晶各剂量组小鼠子宫指数均显著升高(P>
          0.05),子宫内膜也有所增厚;各组小鼠体质量、肝肾功能、肝脏指数、肾脏指数以及白细胞、淋巴细胞、中性粒细胞数量差异均无统
          计学意义(P>0.05),肝肾组织形态无差异;黄体酮组小鼠红细胞数量显著减少(P<0.05),但黄体酮-CNA共晶各剂量组小鼠红细
          胞数量差异均无统计学意义(P>0.05)。结论  成功制备了黄体酮-CNA共晶,提高了黄体酮原料药的水溶性,且所制黄体酮-CNA
          共晶的体内安全性较好。

          ABSTRACT   OBJECTIVE  To  prepare  progesterone-2-chloro-4-nitroaniline  cocrystal (CNA)  so  as  to  improve  the  solubility  of
          progesterone  and  primarily  evaluate  the  safety  of  the  progesterone  cocrystal  in  vivo.  METHODS  Using  progesterone  as  the  main
          body  and  CNA  as  the  ligand,  progesterone-CNA  cocrystal  was  prepared  with  solvent  evaporation  method.  The  cocrystal  was
          characterized  by  X-ray  single  crystal  diffraction,  X-ray  powder  diffraction (XRPD),  differential  scanning  calorimetry (DSC)  and
          Fourier  transform  infrared  spectroscopy (IR).  The  dissolution  rate  of  cocrystal  was  compared  with  those  of  progesterone  and
          physical  mixture.  Forty-eight  female  KM  mice  were  randomly  divided  into  normal  group (phosphate  buffer  containing  0.1%
          dimethyl  sulfoxide),  progesterone  group (16  mg/kg),  CNA  group (9  mg/kg),  progesterone-CNA  cocrystal  low-dose,  medium-
          dose  and  high-dose  groups (6,  12.5,  25  mg/kg),  with  8  mice  in  each  group.  They  were  given  relevant  medicine/solvent
          intramuscularly,  once  a  day,  for  consecutive  14  d.  The  safety  of  cocrystal  was  evaluated  primarily  by  determining/observing  the
          changes  in  body  weight,  organ  index,  tissue  morphology,  blood  routine  indicators,  and  liver  and  kidney  function  indicators.
          RESULTS  The  new  crystal  structure  in  the  X-ray  single  crystal  diffraction  results,  the  new  characteristic  peak  in  the  XRPD
          pattern,  the  change  of  melting  point  in  the  DSC  results,  and  the  change  of  the  characteristic  peak  position  in  the  range  of  3  500-
