Thienopyrimidine-based allosteric inhibitors of the human farnesyl pyrophosphate synthase (hFPPS), characterized by a chiral α-aminophosphonic acid moiety, were synthesized as enantiomerically enriched pairs, and their binding mode was investigated by X-ray crystallography. A general consensus in the binding orientation of all (R)- and (S)-enantiomers was revealed. This finding is a prerequisite for
以手性α-氨基膦酸部分为特征的人类法呢基焦磷酸合酶(hFPPS)的基于噻吩并嘧啶的变构抑制剂被合成为对映体富集对,并通过X射线晶体学研究了它们的结合模式。揭示了所有(R)-和(S)-对映异构体的结合方向的普遍共识。这一发现是建立可靠的构效关系模型的先决条件。
