摘要:
The present invention is related to benzothiophen-2-carbonylguanidine derivatives, a preparation method thereof, and pharmaceutical compositions containing the same. The derivatives have potent inhibitory effect on the sodium/hydrogen exchanger NHE-I, improve the functional recovery of ischemia/reperfusion-induced heart injury in isolated ischemic heart models, and significantly reduce the myocardiac infarct size in in vivo ischemic animal models, thereby showing excellent cardioprotective effects. Also, the derivatives are protective of both neuronal cells and the brain as proven by their protective effects on neuronal cells from necrosis and apoptosis and by their ability to significantly reduce cerebral infarct sizes in in vivo ischemic brain models. The derivatives can be effectively used for the prevention and treatment of ischemic heart diseases such as myocardiac infarction, arrhythmia, angina pectoris and the like, and cerebrovascular diseases such as cerebral stroke and be used as cardioprotective agents to the patients undergoing reperfusion therapy including chemicals such as thrombolytic agents, or surgery such as coronary artery bypass and percutaneous transluminal coronary angioplasty.

A wireless receiver for receiving a multi-contents file and a method for outputting data using the same, which can receive, navigation information for providing intuitively recognizable search interfaces to a user by radio in real time, receive various types of contents files by radio in real time, and output the received information and files through an AV device. A video decoder decodes a video stream on the basis of an MPEG standard. An audio decoder decodes an audio contents file. An OSD processor processes a text file and additional information. A video output unit selectively configures decoded video data and text data on one screen and performs encoding and outputting operations based on the format of a display unit. An audio output unit outputs decoded audio data. A user interface receives a user's command. A WLAN card communicates WLAN data with a computer system. A controller requests the computer system to transmit navigation screen information, at least one contents file or additional information of the contents file edited and processed by the computer system, analyzes a data stream received by radio from the computer system responsive to the request, and performs a control operation so that a result of the analysis is inputted into the decoder or OSD processor. A memory stores the stream and control program data.
