Homocarnosine is a dipeptide composed of GABA and L-histidine that has been found in cerebrospinal fluid and the brain.1 It inhibits lipid peroxidation induced by AAPH when used at a concentration of 10 mM.2 Homocarnosine (1 mM) decreases lactate dehydrogenase (LDH) and prostaglandin E2 release from PC12 cells in an in vitro model of ischemia induced by oxygen-glucose deprivation.3 It reduces infarct area and neurological deficit scores in a rat model of cerebral ischemia-reperfusion injury induced by middle cerebral artery occlusion (MCAO).4 Homocarnosine (5 mg/animal) reduces mortality in a mouse model of subcutaneous S. aureus infection.5

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。
