Abstract:
본 발명은 만성 알레르기성 염증 치료효과를 갖는 IL-5 저해제로서 저분자이면서 비펩타이드 계열 물질인 신규 찰콘계 유도체 및 그의 제조방법, 인터루킨-5 (IL-5) 저해제로서의 용도에 관한 것이다. 본 발명에 의한 신규 찰콘계 유도체는 저분자의 비펩타이드 계열 물질이기 때문에 종래 알려진 알르레기성 염증 치료제와는 달리 단백질에 대한 비특이적 반응이 없기 때문에 알르레기 억제제로 유용하게 활용될 수 있다. 알르레기, 염증, IL-5, 저해제, 억제제, 과민성

Abstract:
PURPOSE: Provided is a cyclohexyl isoflavonone derivative inhibiting IL-5 activity. The derivative inhibits the introduction of eosinophil which is an inflammatory cell causing asthma into the airway, and improves the airway sensitivity to alleviate asthma symptom. CONSTITUTION: The isoflavonone derivative of the formula (1) inhibiting IL-5 activity is provided, wherein R1 is cyclohexylmethoxy, hydrogen or hydroxy; R2 is cyclohexylmethoxy, hydrogen or hydroxy; R3 is hydroxy, -OCH2COOCH3, -OCH2COOH. The method for preparing the isoflavonone derivative of the formula (1) comprises the steps of: reacting a compound of the formula (2) with thallium nitrate trihydrate in lower alcohol to prepare a compound of the formula (1-1); reacting the compound of the formula (1-1) with potassium carbonate and methyl chloroacetate in an organic solvent to prepare a compound of the formula (1-2); and reacting the compound of the formula (1-2) with potassium hydroxide in an organic solvent to prepare a compound of the formula (1-3).
Abstract:
PURPOSE: A novel chalcone-based derivative is provided, which has an interleukin-5 inhibiting effect and a chronic allergic inflammation curing effect and is a low molecule and a non-peptide material. CONSTITUTION: The novel chalcone-based derivative represented by the formula(1) is produced by condensing a compound represented by the formula(2) and a compound represented by the formula(3) in an alcohol solvent in the presence of a base, wherein the alcohol solvent is a C1-C5 alcohol and the base is sodium hydroxide or potassium hydroxide. In the formulas, R1 and R2 are benzyloxy, cyclohexyl methoxy, hydrogen, or hydroxy and R3 is hydroxy or -COOH.
