Definitions
- the present invention relates to a composition for improving memory, learning ability, and cognitive ability.
- the brain has various functions, but the most important function is memory and cognition. If there are no cognitive and memory abilities in the human, it is difficult to perform everyday life and it becomes a problem for survival.
- the memory and cognition are associated with almost all functions of the brain and brain structures associated with the memory and cognition are various and closely connected to almost all brain parts.
- the memory is classified into several steps and divided into a step of registering and encoding information, a storing step, and a step of accessing and withdrawing to a place of memory.
- the encoding refers to an initial process in which information entered into the brain through sensory organs is learned and memorized.
- the information is first stored through the encoding, but in order for the stored information to be continuously retained and stored more firmly, a process after encoding is required and this process is called consolidation. If the consolidation of the memory is not achieved well, memory forgetting occurs rapidly and memory retention becomes difficult.
- the withdrawal means a process of consciously invoking the contents stored in the long-term memory.
- the withdrawal method includes recalling and recognition. The recalling is to invoke consciously the contents of the memory and the recognition is to invoke the contents while hints are applied. In most cases, the recalling is more difficult than the recognition.
- short-term memory is also referred to as working memory, which is a process of performing the next task by using the information after storing the information for a short period.
- the short-term memory means a temporary stay before the information entering the brain hardens to the long-term memory.
- a feature of the working memory is working memory that is usually erased after performing a predetermined task.
- the long-term memory means learning a new task and memorizing the new task again after a predetermined time elapses. Memorizing things which have been experienced in our daily lives or the contents which have been learned again after the time elapses corresponds to almost the long-term memory.
- the memory and cognitive disorders correspond to very serious diseases that make daily life impossible, and includes diseases caused by a wide variety of causes and mechanisms, such as aging, Alzheimer's disease, schizophrenia, Parkinson's disease, Huntington's disease, pick disease, Creutzfeldt-Jakob disease, depression, aging, head injury, stroke, CNS hypoxia, cerebral ischemia, encephalitis, forgetfulness, traumatic brain injury, hypoglycemia, Wernicke-Korsakoff syndrome, drug addiction, epilepsy, fasciola hepatica , hippocampal sclerosis, headache, brain aging, dementia, frontotemporal lobar degeneration, tumor, normal pressure hydrocephalus, HIV, cerebrovascular disease, cerebral disease, cardiovascular disease, amnesia, radiation exposure, metabolic disease, hypothyroidism, mild cognitive impairment, cognitive deficiency and attention deficit.
- causes and mechanisms such as aging, Alzheimer's disease, schizophrenia, Parkinson's disease, Huntington's disease, pick disease, Creutzfeldt-Jakob disease, depression,

Description
- This application is based on and claim priority from Korean Patent Application No. 10-2015-018011, filed on Dec. 21, 2015, with the Korean Intellectual Property Office, the disclosure of which is incorporated herein in its entirety by reference.
- The present invention relates to a composition for improving memory, learning ability, and cognitive ability.
- The brain has various functions, but the most important function is memory and cognition. If there are no cognitive and memory abilities in the human, it is difficult to perform everyday life and it becomes a problem for survival. The memory and cognition are associated with almost all functions of the brain and brain structures associated with the memory and cognition are various and closely connected to almost all brain parts.
- The memory is classified into several steps and divided into a step of registering and encoding information, a storing step, and a step of accessing and withdrawing to a place of memory.
- The encoding refers to an initial process in which information entered into the brain through sensory organs is learned and memorized. The information is first stored through the encoding, but in order for the stored information to be continuously retained and stored more firmly, a process after encoding is required and this process is called consolidation. If the consolidation of the memory is not achieved well, memory forgetting occurs rapidly and memory retention becomes difficult. The withdrawal means a process of consciously invoking the contents stored in the long-term memory. The withdrawal method includes recalling and recognition. The recalling is to invoke consciously the contents of the memory and the recognition is to invoke the contents while hints are applied. In most cases, the recalling is more difficult than the recognition. However, like patients with frontal lobe injury or subcortical vascular dementia, the recalling is difficult, but the recognition is achieved well, and in this case, the encoding and the storing of the memory are performed well, but there is failure of the withdrawal. If there is a memory storage failure, both the recalling and the recognition have the failure.
- In addition, short-term memory is also referred to as working memory, which is a process of performing the next task by using the information after storing the information for a short period. The short-term memory means a temporary stay before the information entering the brain hardens to the long-term memory. A feature of the working memory is working memory that is usually erased after performing a predetermined task.
- The long-term memory means learning a new task and memorizing the new task again after a predetermined time elapses. Memorizing things which have been experienced in our daily lives or the contents which have been learned again after the time elapses corresponds to almost the long-term memory.
- The memory and cognitive disorders correspond to very serious diseases that make daily life impossible, and includes diseases caused by a wide variety of causes and mechanisms, such as aging, Alzheimer's disease, schizophrenia, Parkinson's disease, Huntington's disease, pick disease, Creutzfeldt-Jakob disease, depression, aging, head injury, stroke, CNS hypoxia, cerebral ischemia, encephalitis, forgetfulness, traumatic brain injury, hypoglycemia, Wernicke-Korsakoff syndrome, drug addiction, epilepsy, fasciola hepatica, hippocampal sclerosis, headache, brain aging, dementia, frontotemporal lobar degeneration, tumor, normal pressure hydrocephalus, HIV, cerebrovascular disease, cerebral disease, cardiovascular disease, amnesia, radiation exposure, metabolic disease, hypothyroidism, mild cognitive impairment, cognitive deficiency and attention deficit. In order to solve the memory and cognitive disorders, the related art has made various efforts, but up to now, there have been no reports and application on the efficacy of synthetic peptides having precise sequences as well as substances having an excellent neuroprotective effect and a brain function improving effect against various brain-nervous system diseases.
- The present invention has been made in an effort to provide a peptide for improving memory, learning ability, and cognitive ability.
- In order to achieve the above object, an exemplary embodiment of the present invention provides a peptide including an amino acid sequence with a C-terminal region of GAG.

- In still another exemplary embodiment of the present invention, preferably, the peptide has the number of amino acid residues of 5 to 9, and the peptide has an amino acid sequence of QAGAG, SGGAG, or GAGGAGGAG, but may not be limited thereto.
- The peptide of the present invention has excellent stability by itself, but in order to more largely improve the stability, various protection groups may be bound. Examples of the protection groups include an amino acid group, an acetyl group, a fluorenyl methoxycarbonyl group, a formyl group, a palmitoyl group, a myristyl group, a stearyl group and polyethylene glycol (PEG). The protection groups may be bound to various amino acid residues of the peptide of the present invention, but preferably may be bound to N- or C-terminals.

Further, the composition may be administered by any apparatus in which an active substance may move to a target cell.
- A suitable dose of the pharmaceutical composition may be variously prescribed by factors such as a formulation method, an administration type, age, weight, and gender of a patient, a pathological condition, food, an administration time, an administration route, an excretion rate, and a response susceptibility. A preferable dose of the composition may be in a range of 0.001 to 100 mg/kg based on an adult.

It is understood that the polynucleotide encoding the amino acid sequence includes a nucleotide sequence having substantial identity with respect to the nucleotide sequence. The substantial identity may be a sequence having homology of at least 80%, homology of at least 90%, or homology of at least 95%, in the case of analyzing a sequence which is aligned to maximally correspond to any different sequence from the nucleotide sequence and aligned by using a generally used algorithm in the art.

In the recombinant vector, the polynucleotide encoding the peptide may be operatively linked with a promoter.
- The term “operatively linked” means a functional binding between a nucleotide expression regulatory sequence (for example, a promoter sequence) and a different nucleotide sequence. Accordingly, the regulatory sequence may regulate transcription and/or translation of the different nucleotide sequence by the functional binding.
- The recombinant vector may be typically constructed as a vector for cloning or a vector for expression. The expression vector may use general vectors which are used to express foreign proteins in plants, animals, or microorganisms in the art. The recombinant vector may be constructed by various methods known in the art.

- Scopolamine was purchased from Sigma-Aldrich (St. Louis, Mo., USA). 4-week-old male ICR mice were purchased from Korean BioLink Co. (Chungbuk, Korea). After an adaptation period of one week, the mice were used in a test and all reagents were administered intraperitoneally. Memory disorder was induced by injection of scopolamine before 30 minutes of the test and the synthesized peptides were injected before 30 minutes of the injection of scopolamine.
- A passive avoidance test was performed in the same bright room and dark room. A floor of each room was formed in a shape in which 2-mm stainless steel rods were separated from each other at 1-cm intervals. Bright squares (20×20×20 cm) had 100-W bulbs. These squares were connected to a guillotine door.
- For an acquisition trial, the mouse was placed in the bright room after injection of the reagents and the door was opened after 10 seconds. When the mouse completely entered the dark room, the door was closed and electric shock was applied for 3 seconds. A retention trial was performed after 24 hours of the acquisition trial and the mouse was positioned in the bright room. A latency time of the acquisition and retention trials was measured by a time until the mouse entered the dark room of the box after the door was opened.
- The retention latency in the passive avoidance test represents a long-term memory function in rodents. Accordingly, an effect of a silk fibroin peptide on scopolamine-induced memory deterioration was confirmed by using a step-through passive avoidance test and the result was illustrated in
FIG. 1 . - As illustrated in
FIG. 1 , in the retention trial, a latency time of a normal saline-treated mouse was 180 seconds (maximum cut-off time). It was confirmed that an average of the step-through responses in a scopolamine-injected group with memory deterioration due to injection of scopolamine was significantly lowered as compared with a normal saline-treated group. Before administration of scopolamine, in groups administered with the synthesized peptides, in a peptide-1-injected group consisting of two amino acids, slight improvement was achieved compared with the scopolamine-injected group, and in a peptide-3-injected group, there was a little effect as compared with the scopolamine-injected group. However, it was confirmed that in peptide-2 and peptide-4 to 6-injected groups, the deteriorated memory by scopolamine was improved to be close to a normal group injected with saline. From the above result, it was confirmed that there was a memory improving effect of the peptide of which the C-terminal region ended to GAG, and in order to have the effect, it is confirmed that the peptide should be a peptide in which the length consists of at least four amino acids. - As illustrated in

It was confirmed that an average of the step-through responses in a scopolamine-injected group with memory deterioration due to injection of scopolamine was significantly lowered as compared with a normal saline-treated group. Before injection of scopolamine, it was confirmed that in a group injected with the peptide consisting of 5 to 9 amino acids of the present invention, the memory deteriorated by scopolamine was improved to be close to the normal group injected with saline. From the above result, the memory improving effect of the peptide of which the C terminal region ended to GAG was confirmed. - The mouse was placed at one end of a Y maze with a length of one branch of 30 cm, a width of 5 cm, and a height of 13 cm and the order of entry into each branch was recorded. Alternation was judged to be successful if the mouse sequentially entered three different branches. Spontaneous alternation was defined as Equation below.

FIG. 2 , it was confirmed that the mean of spontaneous alternations of a scopolamine-injected group with memory deterioration due to the injection of scopolamine was significantly lower than that of the normal saline group. In groups injected with the synthesized peptides before injection of scopolamine, it was confirmed that in a peptide-1 and 2 injected group consisting of 2 and 3 amino acids, slight improvement was achieved as compared with the scopolamine-injected group, but in a peptide-3 to 6 injected group consisting of the number of amino acids of 4 to 6, the memory deteriorated by scopolamine was significantly improved. From the above result, it was confirmed that there was a memory improving effect of the peptide of which the C-terminal region ended to GAG, and in order to have the effect, it is confirmed that the peptide should be a peptide in which the length consists of at least four amino acids. - Further, as illustrated in
FIG. 4 , it was confirmed that the mean of spontaneous alternations of a scopolamine-injected group with memory deterioration due to the injection of scopolamine was significantly lowered as compared with the normal saline group. In the group injected with the peptide consisting of 5 to 9 amino acids of the present invention before injection of scopolamine, the memory deteriorated by scopolamine was significantly improved, and in the group injected with peptides ofsequence numbers
