Encoded combinatorial chemistry is provided, where sequential synthetic schemes are recorded using organic molecules, which define choice of reactant, and stage, as the same or different bit of information. Various products can be produced in the multi-stage synthesis, such as oligomers and synthetic non-repetitive organic molecules. Conveniently, nested families of compounds can be employed as identifiers, where number and/or position of a substituent define the choice. Alternatively, detectable functionalities may be employed, such as radioisotopes, fluorescers, halogens, and the like, where presence and ratios of two different groups can be used to define stage or choice. Particularly, pluralities of identifiers may be used to provide a binary or higher code, so as to define a plurality of choices with only a few detachable tags. The particles may be screened for a characteristic of interest, particularly binding affinity, where the products may be detached from the particle or retained on the particle. The reaction history of the particles which are positive for the characteristic can be determined by the release of the tags and analysis to define the reaction history of the particle.
提供了编码组合化学,利用有机分子记录顺序合成方案,将反应物和阶段的选择定义为相同或不同的信息位。在多阶段合成中可以产生各种产物,如低聚物和合成的非重复性有机分子。方便的是,可以使用嵌套的化合物家族作为标识符,其中取代基的数量和/或位置决定了选择。另外,也可采用可检测的官能团,如放射性同位素、荧光剂、卤素等,其中两个不同基团的存在和比例可用于确定阶段或选择。特别是,可以使用多个标识符来提供二进制或更高级的代码,这样只需几个可拆卸的标签就可以定义多个选择。颗粒可根据感兴趣的特性进行筛选,特别是结合亲和性,其中的产物可从颗粒上分离或保留在颗粒上。可以通过释放标签和分析来确定颗粒的反应历史,从而确定颗粒的反应历史。
