A new series of monocyclic pseudopeptidic tachykinin NK-2 receptor antagonists has been derived from nepadutant with the help of site-directed mutagenesis studies and QSAR models. MEN11558 is the lead compound which is evaluated on a series of 13 new human tachykinin NK-2 receptor mutants (Tyr107Ala, Gln109Ala, Asn110Ala, Phe112Ala, Ser164Phe, Cys167Gly, Phe168Ala, Tyr169Ala, Ile202Phe, Trp263Ala,
在定点诱变研究和QSAR模型的帮助下,nepadutant衍生了一系列新的单环拟肽速激肽NK-2受体拮抗剂。MEN11558是先导化合物,已在一系列13种新的人类速激肽NK-2受体突变体(Tyr107Ala,Gln109Ala,Asn110Ala,Phe112Ala,Ser164Phe,Cys167Gly,Phe168Ala,Tyr169Ala,Ile202Phe,Trp263Ala,Tyr269Ala和Tyr269Ahe,Tyr269Ahe和T)上进行评估已有来自nepadutant的数据的8个突变体(Gln166Ala,Ser170Ala,Thr171Ala,His198Ala,Tyr206Phe,Tyr266Phe,Tyr289Phe和Tyr289Thr)。结果表明,两种化合物共享其大多数结合位点,与其假设的结合方式一致。这使我们能够将对尼巴地丁已经拥有的结构知识转移到新的化合物系列
