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.

본 발명은 무선으로 전력을 전송하는 방법, 시스템 및 컴퓨터 판독 가능한 기록 매체에 관한 것이다. 본 발명의 일 태양에 따르면, 무선으로 전력을 전송하는 시스템으로서, 송신 안테나, 상기 송신 안테나와의 사이의 거리가 변화하는 것을 특징으로 하는 수신 안테나, 및 상기 송신 안테나에 전력을 공급하는 D형 전력 증폭기로 구성되는 것을 특징으로 하는 소스를 포함하는 시스템이 제공된다. 본 발명에 의하면, 무선 전력 전송 시스템의 동작 주파수가 고정되어 있고 송신 안테나와 수신 안테나 사이의 거리가 변화는 환경에서도, D형 전력 증폭기 또는 부하 임피던스에 대한 간단한 제어를 수행하는 것만으로 높은 전력 전송 효율을 유지할 수 있게 되는 효과가 달성된다.
Abstract:
The present invention relates to a method, a system and a computer-readable recording medium for wireless power transfer. According to one aspect of the present invention, relating to a system for wireless power transfer, the present invention provides a system which comprises a transmitting antenna, a receiving antenna which changes a distance of the transmitting antenna, and a D-type power amplifier. According to the present invention, even when the operating frequency of a wireless power transfer system is fixed and a distance between the transmitting antenna and the receiving antenna is changed, high power transfer efficiency can be maintained by simply controlling a D-type power amplifier or load impedance.
Abstract:
PURPOSE: A pharmaceutical composition containing a compound which activates AMPK is provided to enhance glucose intake in cells and to prevent and treat type 2 diabetes, hypertension, cardiovascular diseases, and obesity. CONSTITUTION: A pharmaceutical composition for preventing and treating diseases needing AMPK(adenosine monophosphoate-activated protein kinase) activation contains 0.1-50 wt% of a compound of chemical formula I as an active ingredient, or pharmaceutically acceptable salt or solvate thereof. The diseases include type 2 diabetes, metabolic syndrome, hypertension, cardiovascular diseases, and obesity.
Abstract:
PURPOSE: A multiple wireless power transmission method using a time division method and a system thereof are provided to simultaneously transfer power to one receiver using a time division method, thereby blocking influences due to interference among receivers when power is wirelessly transferred. CONSTITUTION: A multiple wireless power transmission system(200) includes a transmitter(210) and a receiver(220). The multiple wireless power transmission system simultaneously transmits power to one receiver using a time division method. The transmitter includes a time dividing unit, a wireless power transmitting unit, and a communication unit. The time division unit of the transmitter divides power transmission time about receivers. The receivers include receiving state controllers, switching units, and communication units.
Abstract:
PURPOSE: A compound which is useful as a two-photon tracer is provided to ensure selective absorption, high solubility, and pH resistance.
