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. | 01-07-2010 |
20100094025 | METHOD FOR PRODUCING C-GLYCOSIDE DERIVATIVE AND INTERMEDIATE FOR SYNTHESIS THEREOF - The present invention provides a method for producing a C-glycoside derivative, which can produce the C-glycoside derivative at a high yield and at a low cost, which conforms to environmental protection, and which is applicable industrially. The C-glycoside derivative is useful for treating and preventing diabetes such as insulin-dependent diabetes (type 1 diabetes), non-insulin-dependent diabetes (type 2 diabetes) and the like and various diabetes-related diseases including insulin-resistant diseases and obesity. | 04-15-2010 |
