- Telomere is a genetic material repeatedly present at the end of a chromosome and is known to prevent damage to the chromosome or binding to another chromosome. Each time a cell divides, the telomeres become slightly shorter. After a certain number of cell divisions, the telomeres become very short, and the cells stop dividing and die. On the other hand, elongation of telomeres is known to prolong cell life. For example, cancer cells secrete an enzyme called telomerase, which prevents telomeres from shortening, so that cancer cells can continue to proliferate without dying. The inventors have confirmed that peptides derived from telomerase are effective in inhibiting angiogenesis and have completed the present invention.

Natural residues are divided into the following groups based on common side chain properties:
- hydrophobic norleucine, met, ala, val, leu, ile
- Non-conservative substitutions will be made by exchanging a member of one of these classes for another class. Any cysteine residue that is not involved in maintaining the proper conformation of the peptide can generally be substituted with serine to improve the oxidative stability of the molecule and to prevent abnormal crosslinking. Conversely, cysteine bond (s) can be added to the peptide to improve its stability.
- Another type of amino acid variant of the peptide is a change in the glycosylation pattern of the antibody.
- change is meant the deletion of one or more carbohydrate residues found in the peptide and / or the addition of one or more glycosylation sites that are not present in the peptide.

- the synthesized peptide was separated from the resin and then purified by HPLC, and confirmed by MS and lyophilized.
- Brown Norway rats were anesthetized and prepared using Shandong (dilated pupils) using 0.5% phenylephrine.
- Angiogenesis was induced in the choroid by irradiating 6-8 times per eye with a 577nm laser (577nm, diode, 10 ⁇ m, 0.05s). Cover glass was attached to the eye during laser irradiation, and the break of the Bruch's membrane was confirmed to be a bubble during laser irradiation using a slit lamp delivery system.
- mice were treated with three doses (0.1, 1, 10 nM) of peptide pep1 prepared by the method described in Example 1 and mice without pep1.
- the drug was administered subcutaneous once a day until 3 days after laser irradiation and up to 2 weeks after laser irradiation after randomization.
- OCT optical coherence tomography
- Pep1 administration group and the control group was in accordance with the experimental group mentioned in Example 2, by measuring the thickness of all lesions (lesion) of each group to determine whether there is a difference in CNV thickness.
- Pep1 administration group and the control group was in accordance with the experimental group mentioned in Example 2, by measuring the area of all lesions in each group to determine whether there is a difference in CNV area for each group.
- Pep1 administration group and the control group was in accordance with the experimental group mentioned in Example 2, by measuring the degree of leakage of all lesions in each group to determine whether there is a difference in choroid by group.
- the CNV activity was measured in three ways including the CNV thickness, CNV area, the lesion rate according to the neovascular leakage, the results showed that the CNV activity decreases when the administration of pep1.
- pep1 has been shown to be effective in the treatment and prevention of CNV-related eye diseases by reducing the activity of CNV. Therefore, it can be seen that the composition containing pep1 can be used for the treatment and prevention of eye diseases as a pharmaceutical composition for the treatment and prevention of eye diseases.
