Abstract:
본발명은 DX2 단백질과 p14/ARF 단백질간의결합을억제하는신규화합물및 이의의학적용도에관한것으로서, 상기화합물은 in vitro 및 in vivo 항암효과를검토한결과항암효과가우수하여폐암을포함한다양한암질환의치료용약제로서유용할뿐 아니라, 특히아드리아마이신과같은항암제내성이야기된세포주에서아드리아마이신의항암제내성이억제되어항암효과가보다증진됨으로써항암효과증진용항암보조제로서도유용하게사용될수 있다.
Abstract:
본 발명은 스네일-p53 간의 결합을 저해하는 화합물 및 이를 유효성분으로 함유하는 암질환 치료제에 관한 것으로, 상기 스네일-p53 간의 결합 저해제는 K-Ras 돌연변이 세포주에서 p53의 발현을 유도함으로써 췌장암, 폐암, 담관암 및 대장암과 같이 진단이나 치료가 용이하지 않은 K-Ras 돌연변이성 암질환을 효과적으로 치료하거나 예방할 수 있다. K-Ras, p53, 암질환, 엔도사이토시스, 스네일

Abstract:
PURPOSE: A specific drug transmission method of K-Ras mutant cell is provided to detect cancer caused by K-Ras mutant in initial, to be very useful for the treatment of cancer, thereby extending the survival rate of cancer patients. CONSTITUTION: A specific drug transmission method comprises: a step of treating DNA bonding domain of p53 and drug for transferring to cells, and a step of transferring drug to neighbored K-Ras mutant cell by endocytosis by the DNA bonding domain of p53.
Abstract:
PURPOSE: A chemical inhibitor for the bond between snail-p53 is provided to effectively treat K-Ras mutagenic cancer disease by inducing the revelation of the p-53 in K-Ras mutant cell strain. CONSTITUTION: A chemical inhibitor has a structure marked as a chemical formula 1. In the chemical formula 1, m is an integer of 0-10, n and p is 0 or 1. In the chemical formula 1, Z is selected from a group comprising NH(CH2)qCH3, -OH, 4-phenylpiperidine group, isobutylamine, and isobutyloxy group and q is integer of 0-9. A pharmaceutical composition for treating cancer disease contains a compound for inhibiting the bond of snail-p53 as an active ingredient.
Abstract:
PURPOSE: A linear double strand RNA molecule reducing expression of different target genes is provided to induce gene silence regardless of inversion orientation of siRNA. CONSTITUTION: A linear double strand RNA molecule contains 2-10 short interference RNAs(siRNA) which are serially connected. The siRNA comprises 18-24 nucleotides. The linear double strand RNA molecule contains two successive siRNAs. Each strand contains two 3'-terminal nucleotides which is not formed in base pair. A recombinant expression vector comprises double strand DNA sequence expressing the linear double strand RNA molecule. The expression of a target gene is suppressed by introducing the recombinant expression vector and linear type double strand RNA molecule in cells.
