Abstract :
(2S,4S)-2-Amino-4-(4,4-diphenylbut-1-yl)-pentane-1,5-dioic acid 1m, is a novel metabotropic glutamate receptor (mGluR) antagonist with insignificant ionotropic affinity. It is a selective antagonist of negatively-coupled cAMP-linked mGluRs with no effect on phosphoinositide coupled mGluRs. A series of 4-substituted glutamic acid analogues were prepared and it was found that compound 1k is tenfold more potent than 1m. Compound 1k has neither significant affinity for ionotropic glutamate receptors nor group 1 and 3 metabotropic receptors.
