All eight stereoisomers of saxagliptin have been synthesized and evaluated for their inhibitory activity against DPP-IV. It was unambiguously confirmed that the configuration of saxagliptin was critical to potent inhibition of DPP-IV. Docking study was performed to elucidate the configuration–activity relationship of saxagliptin stereoisomers. Tyr662 and Tyr470 have been suggested as the key residues
已经合成了沙格列汀的所有八个立体异构体,并评估了它们对DPP-IV的抑制活性。明确证实沙格列汀的构型对有效抑制DPP-IV至关重要。进行了对接研究,以阐明沙格列汀立体异构体的构型与活性之间的关系。Tyr662和Tyr470被认为是DPP-IV与抑制剂相互作用的关键残基。这项工作为进一步设计针对DPP-IV的抑制剂提供了有价值的信息。
