A number of benzothienyl- and benzofurylglyoxylylamine derivatives, which are analogues of previously described indolylglyoxylylamines with a partial agonist activity, are reported in this paper. They were synthesized and tested to verify the importance of the presence of the indole NH group in the interaction of this class of compounds with the benzodiazepine agonist receptor site, since it was reported in literature that a hydrogen bond donor group such as NH was not necessary to elicit an agonist response. Several thienylglyoxylylamine derivatives were also prepared and tested. None of the compounds showed a high affinity at the BzR, demonstrating that the indole NH plays a decisive role in the interaction of the agonist glyoxylylamine ligands with the receptor site.
