Norgestimate is a synthetic progesterone analog.
Progesterone, an endogenous steroid and progestogen sex hormone, is involved in the pregnancy, menstrual cycle, and embryogenesis. Progesterone is reported to belong to steroid hormones, and is the major progestogen in the body. Progesterone is also a crucial metabolic intermediate in the production of other endogenous steroids and plays an key role in brain function as a neurosteroid.
In vitro: Norgestimate was found that, unlike other 19-nortestosterone derivatives, showed high selectivity for the progesterone receptor and low androgenic activity. Moreover, norgestimate and its main active metabolite norelgestromin could not bind to or occupy sex hormone-binding globulin [1].
In vivo: The androgenic and the progestational activity of norgestimate were compared in two animal studies. It was found the difference in the pharmacological response in norgestimate treated rats was equivalent to the difference in the exposure of the animals to either directly administered or metabolically derived levonorgestrel [2].
Clinical trial: Norgestimate (brand names Ortho-Cyclen, Ortho Tri-Cyclen, Previfem, Sprintec, Prefest, others) is a steroidal progestin of the 19-nortestosterone group that is clinically used in combination with ethinylestradiol and in combination with estradiol in menopausal hormone replacement therapy [3].

工作液浓度： mg/ml；
DMSO母液配制方法： mg 药物溶于 μL DMSO溶液（母液浓度 mg/mL，
体内配方配制方法：取 μL DMSO母液，加入 μL PEG300，混匀澄清后加入μL Tween 80，混匀澄清后加入 μL saline，混匀澄清。
1. 首先保证母液是澄清的；
2.
一定要按照顺序依次将溶剂加入，进行下一步操作之前必须保证上一步操作得到的是澄清的溶液，可采用涡旋、超声或水浴加热等物理方法助溶。
