Docosahexaenoic acid is an essential fatty acid and the most abundant ω-3 fatty acid in neural tissues, especially in the retina and brain[1]. (±)19(20)-DiHDPA is one of the major metabolites produced when DHA is incubated with NADPH-supplemented rat liver microsomes.2 DHA is also slowly metabolized by monkey seminal vesicles to (±)19(20)-DiHDPA.3 The route of production likely proceeds through cytochrome P450-catalyzed epoxidation at the ω-3 double bond, followed by conversion to the vicinal diols by epoxide hydrolase[2,3].

计算结果:
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。
