  摘要：

  A study of the neurotropic, neuroprotective, and antioxidant action of the enantiomers and racemate of 2-[(3,7-dioxo-2,4,6,8-tetraazabicyclo[3.3.0]oct-2-yl)]-4-methylthiobutanoic acid synthesized in a stereoselective reaction of (R)-, (S)-, or (R,S)-N-carbamoylmethionine with 4,5-dihydroxyimidazolidine-2-one showed that only (+)-(S)-2-[(1S,5R)-(3,7-dioxo-2,4,6,8-tetraazabicyclo[3.3.0]oct-2-yl)]-4-methylthiobutanoic acid had neuroprotective properties. X-ray structure analysis showed that the predominating racemate of glycolurils is crystallized from aqueous solutions as a conglomerate. Antioxidant activity was not detected.

  The reactions of 4,5-dihydroxyimidazolidin-2-one with chiral S- and R-N-carbamoyl-alpha-amino acids occur diastereoselectively with the formation of corresponding 1R,5S(1S,5R)-glycoluriles as predominant diastereomers; the absolute configuration is determined for three stereoisomers by X-ray diffraction analysis.
