X-Ray Molecular and Crystal Structure of Imidazolopyrroloquinoline, a Main Reaction Product of Pyrroloquinolinequinone (PQQ) and L-Tryptophan in Vitro.
摘要:
通过 X 射线晶体分析确定了咪唑吡咯喹啉(IPQ)的化学结构,IPQ 是吡咯喹啉醌和 L-色氨酸在体外的主要反应产物。IPQ 分子以酮体形式存在,具有三个中性羧基,它们在晶体中形成连续而突出的堆叠结构,并通过范德华、偶极子-偶极子和静电相互作用而得到稳定。晶体中有三种晶体学上独立的二甲基亚砜溶剂,它们通过相邻氧原子之间的分子间氢键来稳定 IPQ 分子的堆积层。
