New methods for the rational identification of molecules capable of interacting with specific naturally occurring proteins are provided, in order to yield new pharmacologically important compounds and treatment modalities. Broadly, the method comprises the steps of identifying a switch control ligand forming a part of a particular protein of interest, and also identifying a complemental switch control pocket forming a part of the protein and which interacts with said switch control ligand. The ligand interacts in vivo with the pocket to regulate the conformation and biological activity of the protein such that the protein assumes a first conformation and a first biological activity upon the ligand-pocket interaction, and assumes a second, different conformation and biological activity in the absence of the ligand-pocket interaction. Next, respective samples of said protein in the first and second conformations are provided, and these are screened against one or more candidate molecules by contacting the molecules and the samples. Thereupon, small molecules which bind with the protein at the region of the pocket may be identified. Novel protein-modulator adducts and methods of altering protein activity are also provided.
提供了一种新的方法,用于理性地识别能够与特定天然蛋白质相互作用的分子,以产生新的在药理学上重要的化合物和治疗方式。广义上,该方法包括以下步骤:识别构成感兴趣特定蛋白质一部分的开关控制配体,同时识别构成该蛋白质一部分并与该开关控制配体相互作用的互补开关控制口袋。该配体在体内与口袋相互作用,以调节蛋白质的构象和生物活性,使得蛋白质在配体-口袋相互作用时呈现第一构象和第一生物活性,并在缺乏配体-口袋相互作用时呈现第二不同构象和生物活性。接下来,提供了处于第一和第二构象的蛋白质的各自样本,并通过接触分子和样本对这些样本进行筛选。然后,可以识别与口袋区域的蛋白质结合的小分子。还提供了新颖的蛋白质调节剂加合物和改变蛋白质活性的方法。
