Definitions
- the present invention relates to an ADP (adenosine diphosphate)-ribose-binding peptide having anticancer activity, and specifically, an ADP-ribose-binding peptide having a specific amino acid sequence and a modification thereof, and pharmaceuticals for preventing or treating cancer containing the same as an active ingredient. It relates to an anti-cancer composition, and a pharmaceutical composition for adjuvant anti-cancer.
- ADP adenosine diphosphate
- PARylation is one of the post-translation modification processes, in which ADP-ribose polymer (poly(adenosine diphosphate-ribose)) is covalently attached to a protein by PAR polymerase. .
- a high-molecular ADP-ribose chain is produced through PARylation, which is a unique intracellular biochemical action that does not show a form such as ubiquitination or SUMOylation and is not a modification at the small molecular level such as acetylation or methylation.
- PARylation is involved in the development of systemic diseases including cancer, viral infection and neurodegeneration.
- PARylation is derived from the activation of PARP-1
- inhibition of PARP-1 activity can be used to treat ovarian cancer, prostate cancer, breast cancer, and cancer.
- Anticancer efficacy targeting other cancers is already well known (J Mateo et al., Ann Oncol., 2019, 30(9): 1437).
- NAD + can impair cellular metabolism, especially oxidative phosphorylation processes that occur in a cellular energy crisis (ATP depletion). It has been suggested that PARylation activation induced by extensive DNA damage consumes NAD + and the subsequent effects of this action may result in cell death.
- PAR polymers released from the nucleus after DNA repair can liberate apoptosis-inducing factors bound to the mitochondrial membrane in the cytoplasm and activate pathways that recruit apoptosis-inducing factors into the nucleus.
- apoptotic factors translocate to the nucleus, they induce cell death by mediating massive DNA fragmentation.
- PARylation-induced energy depletion and apoptosis-inducing factors are known to be related to PAR signaling that controls protein kinase-phosphatase pathways such as the PI3K-Akt pathway or the MAP kinase pathway, and these PAR-dependent cell death processes To a significant extent, it contributes to the complexity of death mechanisms.
- activating PARylation or inhibiting the degradation of PAR polymers can also be a strategy for discovering effective anticancer therapies.
- activation of PARylation or inhibition of PAR polymer degradation is a very promising target in a cancer cell-specific region that undergoes a metabolic process different from that of normal cells.
- the peptides having the novel amino acid sequence of the present invention bind to ADP-ribose and ultimately release ADP-ribose or PAR from the action of various degrading enzymes or signaling proteins in cells.
- the present invention was completed by confirming that PARylation can be overactivated and the decomposition process of PAR polymerase can be disturbed by preventing the polymer from being used, and as a result of this disturbance, cancer cell death can be induced to produce a breakthrough anticancer effect. .

- Another object of the present invention is to provide vectors and transformants containing the polynucleotide.
- Another object of the present invention is a pharmaceutical composition for preventing or treating cancer, comprising the peptide or a pharmaceutically acceptable salt thereof as an active ingredient, and a pharmaceutical supplement for anticancer that enhances the reactivity to a second anticancer agent. It is to provide a pharmaceutical composition for adjuvant anti-cancer to enhance the responsiveness to the red composition and radiation anti-cancer treatment.
- Another object of the present invention is to use the peptide or a pharmaceutically acceptable salt thereof for the prevention or treatment of cancer, and to administer the peptide or a pharmaceutically acceptable salt thereof to a subject in need thereof. It is to provide a method for preventing or treating cancer, including.
- the ADP-ribose binding peptide of the present invention accumulates ADP-ribose in cancer cells, destroys the balance of cells, leads to death of cancer cells, but has excellent anti-cancer effect without being toxic to normal cells, and is not suitable for administration of other anti-cancer drugs or radiation anti-cancer. When administered in combination during treatment, it has a very good effect as an anticancer adjuvant by enhancing the responsiveness to anticancer drugs and radiation therapy.

It was noted that there is In particular, cancer cells continue to divide at a faster rate than normal cells and actively metabolize, so by overactivating PARylation or inhibiting the degradation of PAR polymer, it is possible to specifically target cancer cells without affecting normal cells that do not overactivate PARylation. It was hoped that it could be annihilated.

- the cancer may be solid cancer such as brain cancer, lung cancer, pancreatic cancer, liver cancer, breast cancer, colon cancer, kidney cancer, stomach cancer, and ovarian cancer, but is not limited thereto.
- the solid cancer may be resistant to radiation therapy. Since the anticancer effect of radiation therapy is manifested by the formation of DNA breaks, resistance to radiation therapy is generally determined by mechanisms capable of repairing DNA damage induced by radiation therapy. As a method of increasing the anticancer efficacy of radiation therapy, many attempts have been made to inhibit DNA repair mechanisms, and when repair of damaged DNA strands is blocked, the sensitivity of radiation therapy can be increased.
- the two main types of DNA damage are single strand breaks (SSB) and double strand breaks (DSB). Therefore, it can be described as two categories of recovery paths targeting SSB and DSB.
- Base Excision Repair (BER) is one of several pathways involved in the repair of selected types of DNA SSBs.
- PARP1 plays an important role in the BER of DNA SSBs through a process known as ADP-ribosylation.
- PARP1 senses damage to SSB DNA and recruits the DNA repair complex through ADP-ribosylation to the SSB site for repair. Since the overaccumulation of poly-ADP-ribose synthesized through ADP-ribosylation by PARP-1 activity ultimately leads to cell death, cancer cells use proteasomes such as PARG or ARH3 to prevent this phenomenon. It activates the degradation of poly-ADP-ribose through the activation of survival signaling activity.
- ADP-ribose or ADP-ribose polymer in cancer cells can act as a medium that can disrupt these biochemical survival mechanisms of cancer cells, and can be used as an important anti-cancer adjuvant to overcome resistance to radiation therapy. conceived.
- the ADP-ribose-binding peptide of the present invention when the ADP-ribose-binding peptide of the present invention was treated in combination with low-dose radiation in different cancer types, it was confirmed that the responsiveness to radiation treatment was enhanced in all cancer types (Fig. 15 and FIG. 16). Therefore, the ADP-ribose-binding peptide of the present invention can enhance the response to radiation therapy, so it can be used very usefully as an adjuvant anti-cancer application. Since it has excellent anti-cancer activity even when irradiated with radiation at a tolerable dose, side effects that may occur due to radiation can be minimized.
