Cycloastragenol, a natural tetracyclic triterpenoid, was first identified when screening Astragalus membranaceus extracts for active ingredients with antiaging properties. IC50 value:Target:In vitro: In the study of Cycloastragenolon the treatment of degenerative diseases, the result showed that first-pass intestinal metabolism of cycloastragenol might occur upon passage through the intestinal epithelium. Cycloastragenol underwent extensive metabolism in rat and human liver microsomes with only 17.4% and 8.2%, respectively, of the starting amount of Cycloastragenol remaining after 30 min of incubation [1]. The present study demonstrates that cycloastragenol stimulates telomerase activity and cell proliferation in human neonatal keratinocytes. In particular, cycloastragenol promotes scratch wound closure of human neonatal keratinocyte monolayers in vitro [3]. In vivo: Rats were treated with Cycloastragenol (40 mg·kg- 1·d- 1) for 7 days to induce hepatic microsomal enzyme. The result showed that compared with the control, cycloastragenol obviously activated CYP2E1, and remarkably inhibited CYP3A4 [2].

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。
