Abstract:
본 발명은 혈청 아밀로이드 A 억제제 또는 포밀펩타이드 수용체 2 활성 조절제를 포함하는 거품세포 형성 억제용 약학적 조성물 및 이를 이용하여 죽상동맥경화증을 예방 또는 치료하는 방법에 관한 것이다. 본 발명의 조성물을 이용하여 거품세포 형성을 효과적으로 억제할 수 있다. 이 때 백일해 독소 민감형 G 단백질 의존적 신호 전달 경로에 영향을 주지 않아 부작용을 최소화시킬 수 있다. 거품세포 형성은 죽상동맥경화증의 병인론에서 결정적인 단계에 해당한다. 따라서 본 발명의 조성물은 죽상동맥경화증을 비롯한 거품세포 형성과 관련된 질병들을 치료 및 예방하는데 중요하게 응용될 수 있을 것으로 기대된다.
Abstract:
The present invention relates to a pharmaceutical composition for inhibiting foam cell formation containing serum amyloid A synthesis inhibitors or formyl peptide receptor 2 activity modulators, and a method of preventing and treating atheriosclerosis. The formation of foam cells can be effectively inhibited by using the composition of the present invention. During the foam cell formation inhibition, the composition does not affect a pertussis toxin sensitive G protein dependent signaling pathway and is capable of minimizing side effects. The foam cell formation is a critical phase of the etiology of the atheriosclerosis. Therefore, the composition of the present invention is expected to be significantly applied to the prevention and treatment of diseases related to the foam cell formation including atheriosclerosis.
Abstract:
PURPOSE: A novel peptide is provided to promote intracellular calcium ion release through activation of phospholipase C and to act on leukocytes, and to promote reactive oxygen generation. CONSTITUTION: A peptide contains an amino acid sequence selected from the group consisting of sequence numbers 1-3. The peptide regulates activity of neutrophil. The peptide induces increase of intracellular calcium ions, stimulates cell chemotactic motion, and specifically acts on leukocytes. The peptide of sequence number 2 or 3 induces superoxide generation in human neutrophil. The peptide of sequence number 1 or 3 act on FPR1(formyl peptide receptor 1). The peptide of sequence number 2 act on FPR2(formyl peptide receptor 2). A pharmaceutical composition contains pharmaceutically effective amount of the peptide.
Abstract:
PURPOSE: An FPR2 liang having palmitic acid conjugated to peptide sequence of intracellular loop 3 is provided to effectively enhance immune response of leukocytes. CONSTITUTION: An FPR2 ligand is prepared by binding palmitic acid to a peptide sequence of intracellular loop 3 of formyl peptide receptor 2. The peptide sequence is KIHKKGMIKSSRPLRV. A pharmaceutical composition for treating tumor, infection, and inflammatory diseases contains the ligand as an active ingredient. The pharmaceutical composition further contains sterile water, saline solution, dextrose, glycerol, ethanol, emulsifier, suspension, surfactant, stabilizing agent, excipient, preservative, or binder.
