The invention relates to a general process by which recombinantly derived variable domains of antibodies encompassing either or both light and heavy variable regions with or without respective constant regions are engineered and selected for identification of unique surface domains of pharmaceutical targets or parts thereof which regulate target function. The recombinant antibodies are useful as reagents for high volume, rapid screening of occupation of the active surface domains by natural or synthetic entities. This invention is also directed to elucidating the three-dimensional conformation of the antibodies, or parts thereof, which bind to the pharmaceutical targets and confers activity. Methods for creating high resolution molecular models which can direct the synthesis of biologically active small organic molecules useful as viable discovery drug leads are also provided.
本发明涉及一种通用工艺,通过该工艺,重组衍生的抗体可变结构域(包括轻型和重型可变区,以及或不包括各自的恒定区)被设计和筛选出来,用于识别药物靶点或其部分的独特表面结构域,从而调节靶点功能。重组抗体可作为试剂,用于大量、快速筛选天然或合成实体对活性表面结构域的占用。本发明还旨在阐明抗体或其部分的三维构象,这些构象与药物靶点结合并赋予活性。本发明还提供了建立高分辨率分子模型的方法,这些模型可以指导合成具有生物活性的有机小分子,作为可行的药物发现线索。
