Abstract:
Provided of the present invention is a method for identifying a target protein of a physiologically active low molecular compound using a probe and a negative probe labeled with fluorescents having different wavelengths. The probe can be conjugated with a target protein binding to the physiologically active low molecular material and also be conjugated with proteins not binding to the physiologically active low molecular material. Therefore, a negative prove labeled with a fluorescent of a wavelength different from a fluorescent conjugated with the probe can be used, or a physiologically active low molecular substance and the probe can be also used.
Abstract:
Provided in the present invention are benzopyran derivatives inhibiting formation of microtubule, a pharmaceutically acceptable salt of the same, and a pharmaceutical composition containing the same as active component for treating cancer. A microtubule is in a state of single body and polymer to be controlled according to a need to control cell division, thus blocks movement between single body and polymer of the microtubule to inhibit cell division. The benzopyran derivatives of the present invention inhibit formation of microtubule to be used for treating cancer and other hyperproliferative diseases.

The diseases include type 2 diabetes, metabolic syndrome, hypertension, cardiovascular diseases, and obesity.
Abstract:
Provided are a novel compound with a spiro chiral carbon backbone, a stereoisomer thereof, an enantiomer thereof, an in vivo hydrolysable precursor thereof, or a pharmaceutically acceptable salt thereof. The novel compound with the spiro chiral carbon backbone has excellent osteoblast differentiation activity, mast cell inhibitoryactivity, and fatty acid synthesis inhibitory activity in the liver. Therefore, the novel compound can be expected to play an innovative role in treatment of osteoporosis, fatty liver, and obesity.
Abstract:
본 발명은 AMPK(Adenosine monophosphate-activated protein kinase; AMP-activated protein kinase)를 활성화시키는 화합물을 유효성분으로 함유하는, AMPK의 활성화가 필요한 질환의 예방 및 치료용 약학조성물에 관한 것이다. AMPK는 비만 및 제2형 당뇨병을 포함하는 대사 장애의 치료를 위한 매력적인 표적 분자로서 부각되고 있다. 본 발명자들은 간접적인 AMPK 활성제(activator)로서 특별한 벤조피란 부분구조(privileged benzopyran substructure)를 갖는 신규한 저분자, 특히 앰프키논(ampkinone, AKN)을 발견하였으며, 이는 다양성-지향적 합성(diversity-oriented synthesis)에 의해 구축된 저분자 라이브러리로부터 유래된다. AKN은 다양한 세포주 내에서 AMPK의 간접적 활성화를 통해 AMPK의 인산화(phosphorylation)를 자극(stimulate)하였다. AKN-매개된 AMPK의 활성화는 LKB1의 활성을 필요로 하였으며, 근육세포에서 증가된 글루코스 섭취(uptake)를 야기하였다. 또한, AKN-처리된 DIO(Diet-induced obesity) 마우스는 총 체중 및 전체 지방 질량이 현저하게 감소되었다. 지질 파라미터의 조직학적 검사 및 측정은, DIO 마우스 모델에서의 대사 이상(metabolic abnormality)을 AKN이 효과적으로 개선시켰음을 나타내었다. 따라서, 본 발명의 특별한 벤조피란 부분구조(privileged benzopyran substructure)를 갖는 저분자인 AKN은 AMPK의 간접 자극을 통해 항당뇨 및 항비만 치료용 치료제의 신규 클래스로서의 잠재성을 갖는다.
