专利号:US-6245919-B1 优先权日:1996-06-28 标 题:Cyclopropylglycine derivatives and agonists for metabotronic L-glutamate receptors 发明人:SHINOZAKI HARUHIKO; TAGUCHI TAKEO; ISHIDA MICHIKO 权利人:SHINOZAKI HARUHIKO; TAGUSHI TAKEO; NIPPON CHEMIPHAR CO 摘要:A cyclopropylglycine derivative having the following formula:and an intermediate compound for the synthesis of the cyclopropylglycine derivative are novel compounds. The cyclopropylglycine derivative shows a selectivity higher than that of the known agonists to metabotropic L-glutamate receptors, and therefore is a metabotropic type agonist to L-glutamate which has excellent characteristics.
