A Virtual Screening Hit Reveals New Possibilities for Developing Group III Metabotropic Glutamate Receptor Agonists
摘要:
(R)-PCEP (3-amino-3-carboxypropy1-2'-carboxyethyl phosphinic acid, 1), a new metabotropic glutamate receptor 4 (mGlu4R) agonist, was discovered in a previously reported virtual screening. The (S)-enantiomer and a series of derivatives were synthesized and tested on recombinant mGlu4 receptors. A large number of derivatives activated this receptor but was not able to discriminate between mGlu4 and mGlu8 receptors. The most potent ones 6 and 12 displayed an EC50 of 1.0 +/- 0.2 mu M at mGlu4R. Interestingly these agonists with longer alkyl chains revealed a new binding pocket adjacent to the glutamate binding site, which is lined with residues that differ among the mGluR subtypes and that will allow the design of more selective compounds. Additionally 6 was able to activate mGlu7 receptor with an EC50 of 43 +/- 16 mu M and is thus significantly more potent than L-AP4 (EC50 of 249 +/- 106 mu M).
