pharmacological effects with improved hygroscopicity and thermal stability. Methods: The novel dapagliflozin ester prodrugs containing pharmaceutically acceptable moieties were synthesized and their pharmacokinetics (PK) and physical properties were compared with dapagliflozin propanediol hydrate (DPD, Farxiga®). The PK in dog and rat, in vitro stability, hygroscopicity, and physical property studies in accelerated
背景:Dapagliflozin作为SGLT-2抑制剂而开发,具有低熔点和高吸湿性,在药物生产过程中需要格外小心以保持活性药理特性。已经进行了各种尝试来克服这些有问题的特性。 目的:开发达格列净前药,这些药具有相似的药理作用,并具有改善的吸湿性和热稳定性。 方法:合成含有药物可接受部分的新型达格列净酯前药,并与达格列净丙二醇水合物(DPD,Farxiga®)比较其药代动力学(PK)和物理性质。用前药在加速条件下(40°C,75%RH)进行了犬和大鼠的PK,体外稳定性,吸湿性和物理性质研究。 结果与讨论:在8种合成前药中,前药8b的Cmax和AUC0-48h值(分别为1.35μg/ ml和14.78μg·h / ml)与DPD相似(1.67μg/ ml和14.27μg·h) / ml)。但是,其余的前药8a,8c,8d,8e,8f,8g和8h的Cmax和AUC0-48h值均明显低于DPD。前药8b在体内完全转化为母体药物。
