rac-Mono(ethylhexyl) phthalate (MEHP) is a metabolite of di(2-ethylhexyl) phthalate (DEHP), commonly used as a plasticizer and an identified environmental contaminant, and an agonist of peroxisome proliferator-activated receptor γ (PPARγ).1 It binds to PPARγ when used at concentrations of 50 and 100 ?M and activates PPARγ in a reporter assay using HEK293H cells (EC10 = 1.2 ?M). MEHP (30, 100, and 300 ?M) accumulates in 3T3-L1 adipocytes and increases lipolysis, glucose uptake, and energy metabolism, as well as reduces the size of lipid droplets when used at concentrations of 100 and 300 ?M.2 It also increases the expression of the thermogenesis-related genes Usp1, Cidea, Prdm16, and Trpv1 in 3T3-L1 adipocytes.3 Urinary levels of MEHP in women positively correlate with the risk of unexplained recurrent spontaneous abortion (URSA).4

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。
