BACKGROUND OF THE INVENTION With the rapid growth of the elderly population, the number of people suffering from Alzheimer's disease has also increased dramatically. Alzheimer's disease is also known as the Alzheimer type dementia or the senile dementia of the Alzheimer type.
- Alzheimer's disease is the most common type of Alzheimer's disease. It has become the sixth leading cause of death in the United States and the fifth leading cause of death among Americans aged 65 and over. Although scientists have conducted extensive and in-depth research on this disease, to date, the exact cause of the disease remains unclear. Alzheimer's disease is a progressive disease that constantly kills nerve cells, destroys nerve connections in the brain, and causes tissue in the brain to be destroyed, causing patients to gradually lose memory, consciousness, and judgment, and cause The patient developed emotional disorders and behavioral disorders.
- Alzheimer's disease is an irreversible disease, and there is no medicine to prevent it, and no medicine can cure it or delay the progression of it.
- the drugs currently used to treat the disease can only alleviate or ameliorate the symptoms of the disease.
- Acetylcholine is a neurotransmitter that is a chemical released by the nerves. If the system that produces acetylcholine in the brain, the cholinergic system is damaged, it can cause Alzheimer's disease. Memory impairment; and the function of acetylcholinesterase is to catalyze the hydrolysis of acetylcholine, ie, acetylcholine.
- acetylcholinesterase inhibitors include donepezil and tacrine. , rivastigmine and galantamine, wherein donepezil (Sugimoto et al. US4895841 and 5100901; Pathi et al. WO 2007077443; Parthasaradhi et al. WO 2005003092; Dubey et al.

- the model of learning and memory impairment induced by injection of ⁇ 1-42 into the lateral ventricle is the most commonly used animal model for evaluating whether a compound has improved learning and memory.
- the animal model significantly destroys the learning ability and memory function of the animal, and the mechanism of affecting memory is clear, the result is easy to repeat, and there is no obvious non-specific effect.
- Morris water maze test and lateral ventricle injection of A ⁇ 1-42 induced learning and memory impairment model were used to evaluate the learning and memory of rats at different concentrations (0.7 mg/Kg, 3.5 mg Kg 7 mg/g). Improvement.
- Experimental materials and grouping were used to evaluate the learning and memory of rats at different concentrations (0.7 mg/Kg, 3.5 mg Kg 7 mg/g). Improvement.
- mice SD, male (220 soil 20g), animals are kept in the light and dark alternate (12 h: 12 h) clean animal room, free to eat drinking water. The animals were tested after 3 days in the animal room to adapt to the environment.
- ⁇ ⁇ 1-42 is formulated into 2 ⁇ / ⁇ 1 according to the instructions.
- Donepezil hydrochloride control group donepezil hydrochloride (DPH) (3 mg/Kg) + lateral ventricle injection A ⁇ 1-42
- Experimental equipment Rat Morris water maze device, brain stereotaxic instrument.
- SD rats were randomly divided into normal control group, lateral ventricle injection ⁇ ⁇ 1-42 model group, positive control group (donepezil hydrochloride 3 mg/Kg) and test group 1-33 (0.7 mg/kg, 3.5 mg/Kg). And 7 mg/kg group); "In the lower control group, the lateral ventricle was injected with 5 ⁇ of normal saline, and the other groups were injected with ⁇ ⁇ 1-42 5 ⁇ /only. The rats were recovered for one week after the operation and subsequent experiments were performed.
- the normal control group and the lateral ventricle were injected with ⁇ ⁇ 1-42 model group to give the corresponding solvent every morning at a fixed time; the 1-33 group and the donepezil hydrochloride control group were given the corresponding doses of the drug for 8 days.
- the water maze experiment was started on the 5th day, and the formal water maze test was performed on the 9th day. Try.
- the acute toxicity test refers to the "Technical Guidelines for Acute Toxicity Test of Chemical Drugs", and the representative hydrochlorides of the compounds 1-29 of the present invention (1-33) and the hydrochlorides of the compounds 1-17 (1-34) The mice were subjected to preliminary acute toxicity experiments.
- Acute toxicity test of donepezil hydrochloride 1. Intravenous injection: Animals were divided into 6 groups of 5 each; the doses used in 6 groups were: 4.00 mg/kg, 3.60 mg/kg, 3.24 mg/kg, 2.92 mg/kg, 2.62 mg/kg and 2.36. Mg/kg. Each tail vein was injected once and observed for 1W.
- Intravenous injection Animals were divided into 6 groups of 5 each; the doses used in 6 groups were: 50.00 mg/kg, 40.00 mg kg, 32.00 mg/kg, 25.60 mg/kg, 20.48 mg/kg and 16.18 mg /kg. Each tail vein was injected once and observed for 1W.
- Intravenous injection Animals were divided into 5 groups of 5 each; the doses used in the 5 groups were: 25.60 mg/kg, 23.04 mg/kg, 20.25 mg/kg, 18.23 mg/kg and 16.40 mg/kg, respectively. Each tail vein was injected once and observed for 1 W.
- the toxicity and mortality of the animals after administration were observed, and the mortality was statistically analyzed.
- the results were analyzed by LD50 data processing software.
- Inhibition activity compared with donepezil hydrochloride, 1-17 and 1-29 or its hydrochloride (1-33) showed a stronger effect of improving learning and memory in the Morris water maze test, showing better In vivo efficacy; particularly striking is 1-29 or its hydrochloride (1-33), although the compound has a weaker acetylcholinesterase inhibitory activity in vitro, only about 10% of donepezil hydrochloride, but has a ratio Donepezil hydrochloride has better in vivo efficacy, and the antioxidant effect is stronger than donepezil hydrochloride.
