Abstract:
PURPOSE: A nucleolin-specific aptamer is provided to function as a nucleolin inhibitor and be used as an agent suppressing the dysplasia of a cell, thereby usefully used for the treatment of hyper-proliferative disease such as cancer. CONSTITUTION: A nucleolin-specific aptamer includes a sequence in which at least one thymidine (T) existing in a sequence number 3 is respectively substituted with deformation pyrimidine nucleoside. The deformation pyrimidine nucleoside is one among deoxyuridine (dU) having a hydrophobic group in 5-position, deoxycytidine (dC), uridine (U) and cytidine (C). A sequence number 3 is NGGTGGTGGTGGTTGTGGTGGTGGTGGN. In the sequence number 3, each N is nonexistence or one nucleoside selected from a group consisting of adenosine (A), thymidine (T)/uridine (U), cytidine (C) and guanosine (G).
Abstract:
본 발명은 리포터 유전자를 포함하는 변이 C 형 간염 바이러스, 효율적으로 복제하는 변이 C 형 간염 바이러스 및 상기 변이 C 형 간염 바이러스를 이용한 항 C 형 간염 바이러스 물질의 스크리닝 방법에 관한 것이다. 본 발명은 많은 바이러스가 생성되지 않아 효율적으로 바이러스 감염을 유도할 수 없고, 바이러스의 감염의 정량적 측정이 어렵다는 기존의 HCV 세포배양법의 문제점을 극복하기 위하여 개발된 것이다. 본 발명은 많은 HCV 를 생성하고 감염을 살아있는 세포를 그대로 이용하여 효율적으로 관찰할 수 있으므로, 본 발명을 이용한 시스템에 의해, 기존의 HCV 연구에서 불가능하였던 바이러스 감염경로, 바이러스의 조립(assembly) 및 바이러스의 배출(release)에 관한 연구를 수행할 수 있고, HCV 복제 외에도 HCV 의 생활사의 다른 중요한 부분을 억제할 수 있는 억제제를 찾는 연구를 수행할 수 있다.
Abstract:
PURPOSE: An aminoquinolone compound, or pharmaceutically acceptable salt or hydrate thereof with excellent anti-proliferation with respect to hepatitis C virus(HCV) is provided to prevent or treat hepatitis, liver cirrhosis, or liver cancer activity. CONSTITUTION: An aminoquinolone compound is denoted by chemical formula 1. A pharmaceutical composition for preventing or treating hepatitis, liver cirrhosis, or liver cancer contains an aminoquinolone compound of chemical formula 2, or a pharmaceutically acceptable salt or hydrate thereof as an active ingredient. An antiviral composition contains the aminoquinolone compound of chemical formula 2, or a pharmaceutically acceptable salt or hydrate thereof as an active ingredient. Mammalian HCV-infected cells are treated using the antiviral composition.
Abstract:
PURPOSE: A DNA aptamer which specifically binds itself to a breast cancer-related Her2(ERBB2) receptor is provided to effectively suppress metastasis and to diagnose cancer. CONSTITUTION: An ERBB2 aptamer specifically binds itself to ERBB2 and has a base of sequence number 7. The ERBB2 aptamer additionally contains a sequence of sequence number 39 or 40 linked to 5' end and a sequence of sequence number 41 or 42 linked to 3' end. A pharmaceutical composition for treating cancer contains the ERBB2 aptamer as an active ingredient. The cancer includes breast cancer, colon cancer, lung cancer, gallbladder cancer, pancreatic cancer, or gastric cancer. A composition for diagnosing cancer contains the ERBB2 aptamer as an active ingredient.
Abstract:
PURPOSE: A DNA aptamer which specifically binds to bread cancer-related Her2(ERBB2) receptor and a composition containing the same are provided to effectively suppress and diagnose cancer. CONSTITUTION: An ERBB2 aptamer specifically binds to ERBB2 and contains 5-15 bases which are substituted with a hydrophobic functional group of a naphthyl group, a benzyl group, a pyrrolbenzyl group, or tryptophane at 5` of dUTP(deoxyuracil). The ERBB2 aptamer contains 40-100 bases including bases selected from sequence numbers 1-35. The ERBB2 aptamer contains 40-100 bases including a base of sequence number 7 or 11. The ERBB2 aptamer additionally contains 15-30 bases at 5` end, 3`end, or both ends of a base sequence selected from sequence numbers 1-35. A pharmaceutical composition for treating cancer contains the ERBB2 aptamer as an active ingredient. A composition for diagnosing cancer contains the ERBB2 aptamer as an active ingredient.
