ZSET-845 is a cognitive enhancer which enhances choline acetyltransferase activity in the hippocampus in the rat.
ZSET-845 has no inhibitory action on AChE activity and enhances choline acetyltransferase (ChAT) activity in NB-1 cells[1].
Treatment with ZSET-845 at the dose of 0.01, 0.1 and 1 mg/kg significantly ameliorates impaired performance caused by scopolamine. Oral administration of ZSET-845 causes an increase in ChAT activity in the hippocampus. In the hippocampus, ZSET-845 (0.01, 0.1 or 1 mg/kg) significantly increases ChAT activity (112%, 113.8% or 108.7%, respectively) compared with matched vehicle-injected control rats[1]. Oral administration of ZSET845 at a dose of 1 or 10 mg/kg ameliorates learning impairment in passive avoidance task and enhanced ChAT activity in the basal forebrain, medial septum and hippocampus, and increases in the number of ChAT-immunoreactive cells in the medial septum in Ab-treated rats to the levels of vehicle-injected control rats[2].

Animal experiment: | Rats: The passive avoidance apparatus consists of a small illuminated chamber and a larger dark chamber. The two chambers are separated by a guillotine door. On the first and second days of testing, each rat is placed in the apparatus and left for 3 min to habituate to the apparatus. On the third day, an acquisition trial is performed. Oral administration of ZSET-845 (0.001, 0.01, 0.1 or 1 mg/kg), donepezil or tacrine (0.01, 0.1, 1 or 10 mg/kg) is given 60 min before the acquisition trial. Scopolamine (2 mg/kg) is intraperitoneally (i.p.) injected 20 min before the acquisition trial. Matched control rats received vehicle only[1]. |

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。
