ABSTRACT
Alzheimer's disease ( AD ) is a complex disease caused by environmental and genetic factors. Therefore, one-drug-multiple-target compounds represent the most promising pharmacological approaches to preventing and treating this dis-ease. We have previously designed and synthesized bis( n)-Cog-nitin, novel anti-Alzheimer's dimers derived from tacrine. Bis ( n)-Cognitin have been proven to act on multiple important AD targets, including acetylcholinesterase, β-secretase, N-methyl-D-aspartic acid receptor and neuronal nitric oxide synthase, con-currently. Moreover, Bis(n)-Cognitin could inhibit β-amyloid-induced neurotoxicity, decrease glutamate-induced excitotoxici-ty, reduce oxidative stress, improve learning and memory, and protect against neuronal apoptosis in various in vitro and in vivo models, suggesting that bis ( n )-Cognitin are potential anti-AD drug candidates.
ABSTRACT
To study on the four natures (cold, hot, warm, and cool) of Chinese materia medica (CMM) is a central and knotty issue in the field of traditional Chinese medicine (TCM) and no substantial progress has been made so far, which is an obstacle in the course for the modernization of TCM. By application of apoptosis for researching the four natures of CMM, the relationship between the biological efficiency and apoptosis has been explained in a qualitative and quantitative way. A pattern recognition system for the four natures of CMM has been set up in a molecular level. That is a breakthrough to measure the four natures of CMM. Based on the abundant literatures at home and abroad, and the study done as well, the original thinking and fresh viewpoint on the orientation and development for the four natures of CMM have been put forward and then the explanation and prospective analysis on them have been carried out.
