概要

• 論文の詳細を見る

• The chemical structure of imidazolopyrroloquinoline (IPQ), a main reaction product of pyrroloquinolinequinone and L-tryptophan in vitro, has been determined by X-ray crystal analysis. The IPQ molecules exist in keto form, having three neutral carboxyl groups, and they form continuous and prominent stacking structures in a crystal which are stabilized by van der Waals, dipole-dipole and electrostatic interactions. There are three crystallographically independent dimethyl sulfoxide solvents in a crystal, and they stabilize the stacking layers of IPQ molecules by intermolecular hydrogen bonds between neighboring oxygen atoms.
