Library, or molecular diversity, approaches are a progressive tool in contemporary investigation of biological interactions and drug discovery. All library approaches include certain degree of rationality and cannot be therefore classified as random or irrational techniques. Reviewed techniques are complementary to so called "rational design"; they can serve either as a tool to generate a lead, or, on the other hand, to optimize a "designed" lead by rapid evaluation of structure-activity relationships. Combinatorial approaches are based on either a random or multiple principle which enables production of large number of diverse molecular structures that can be simultaneously screened and evaluated in a biological assay to find an optimal interacting molecule.
图书馆或分子多样性方法是当代
生物相互作用和药物发现研究中的一种先进工具。所有图书馆方法都包含一定程度的合理性,因此不能被归类为随机或非理性技术。回顾的技术是所谓的“理性设计”的补充;它们既可以作为生成引导的工具,也可以通过快速评估结构活性关系来优化“设计”的引导。组合方法基于随机或多重原理,可以生产大量不同的分子结构,这些结构可以同时在
生物测定中进行筛选和评估,以找到最优的相互作用分子。
