在过去的二十年里,随着IMiD和indisulam等MG降解剂的出现,分子胶(MGs)逐渐引起了制药界的关注。这些分子通过促进靶蛋白和E3连接酶之间的相互作用来降解靶蛋白。此外,MGs作为化学诱导剂,促进同源蛋白和异源蛋白的二聚化形成三元复合物,...在过去的二十年里,随着IMiD和indisulam等MG降解剂的出现,分子胶(MGs)逐渐引起了制药界的关注。这些分子通过促进靶蛋白和E3连接酶之间的相互作用来降解靶蛋白。此外,MGs作为化学诱导剂,促进同源蛋白和异源蛋白的二聚化形成三元复合物,在调节生物活性方面具有很大的前景。本文重点介绍MGs在药物开发领域的应用,包括蛋白质–蛋白质相互作用(PPI)稳定性和蛋白质降解。我们深入分析了各种MGs的结构以及MGs与各种生物活性分子之间的相互作用,从而为PPI稳定剂和新型降解剂的开发提供了新的视角。Over the past two decades, molecular glues (MGs) have gradually attracted the attention of the pharmaceutical community with the advent of MG degraders such as IMiDs and indisulam. Such molecules degrade the target protein by promoting the interaction between the target protein and E3 ligase. In addition, as a chemical inducer, MGs promote the dimerization of homologous proteins and heterologous proteins to form ternary complexes, which have great prospects in regulating biological activities. This review focuses on the application of MGs in the field of drug development including protein-protein interaction (PPI) stability and protein degradation. We thoroughly analyze the structure of various MGs and the interactions between MGs and various biologically active molecules, thus providing new perspectives for the development of PPI stabilizers and new degraders.展开更多
由于PPI网络数据的无尺度和小世界特性,使得目前对此类数据的聚类算法效果不理想.根据PPI网络的拓扑结构特性,本文提出了一种基于连接强度的蚁群优化(Joint Strength based Ant Colony Optimization,JSACO)聚类算法,该算法引入了连接强...由于PPI网络数据的无尺度和小世界特性,使得目前对此类数据的聚类算法效果不理想.根据PPI网络的拓扑结构特性,本文提出了一种基于连接强度的蚁群优化(Joint Strength based Ant Colony Optimization,JSACO)聚类算法,该算法引入了连接强度的概念对蚁群聚类算法中的拾起/放下规则加以改进,以连接强度作为拾起规则,对结点进行聚类,并根据放下规则放弃部分不良数据,产生最终聚类结果.最后采用了MIPS数据库中的PPI数据进行实验,将JSACO算法与PPI网络数据的其他聚类算法进行比较,聚类结果表明JSACO算法正确率高,时间开销低.展开更多
This paper focuses on the demonstration study, through related analysis on various samples, on the relation between PPI and CPI, based on the resident consumption price index and the price index of industrial products...This paper focuses on the demonstration study, through related analysis on various samples, on the relation between PPI and CPI, based on the resident consumption price index and the price index of industrial products in Shandong province since 1989. The paper also analyzes the relation among different price index’s, their transfer regulation and the degree of influence on one another. The study result shows that resident consumption price index relates the most to the factory price index of daily living products, the second to the factory price index of production materials, and the least to the purchase price index of raw materials, fuel and power. The price change of energy and raw materials at the upper level will naturally be reflected in the factory price of industrial products at the lower level and price of daily living products in the end. It is a long influence process from the price of raw materials for industrial production to the factory price of industrial products, including production materials and daily living products, and finally to the resident consumption price. The price influence process somehow lags behind the production and consumption process for a certain period. The rise and fall of industrial products price index is the earliest signal for economic development trend and to which the government and the industry must attach high importance.展开更多
