    摘要： (2S,1'R,2'R,3'R)-2-(2,3-dicarboxycyclopropyl)-glycine (DCG-I) and (2S,1'S,2'S,3'S)-2-(2,3-dicarboxycyclopropyl)glycine (DCG-II), as well as methods for synthesizing these compounds are provided. Studies on L-glutamate receptors with the use of DCG-I and DCG-II, which are agonists for NMDA receptors, contribute to the development of remedies for various nervous disorders. Further, DCG-I and DCG-II selectively inhibit monosynaptic reflex even at a low concentration, which makes them useful as a remedy for spastic palsy, an anesthetic and an analgesic.

    摘要： A method for effectively causing charge-remote fragmentation (CRF) when the structural analysis of an nitrogen-containing organic compound is performed using a high-energy collisional-induced dissociation-mass/mass spectrum (CID-MS/MS spectrum), a reagent to be used in such a method, and a method for analyzing an organic compound by the induction of CRF are provided. The method for the induction of charge-remote fragmentation (CRF) using a high-energy collisional-induced dissociation-mass/mass spectrum (CID-MS/MS spectrum) has the step of: introducing a squaric acid residue into an end of a nitrogen-containing organic compound. The squaric acid residue is represented by a chemical formula (I): The reagent is provided for introducing such a squaric acid residue. Furthermore, the method is provided for analyzing such an organic compound by the induction of CRF.
