  Development of Selective Ligands for Benzodiazepine Receptor Subtypes by Manipulating the Substituents at Positions 3- and 7- of Optically Active BzR Ligands

  摘要：

  Two series of analogs of the optically active alpha5 subtype selective imidazobenzodiazepine 20 have been prepared. The framework constrained analogs were synthesized by variation of the C (3) ethyl ester function 20 to either t-butyl 7 or 2, 2, 2-trifluoroethyl 14. In both cases receptor binding was decreased; as well as alpha5 selectivity. In the second series the 7-acetylenyl function in 14 was varied over the range vinyl, 2-furyl, 2-thienyl and 2-phenyl. Again receptor binding was maintained in most cases; however, alpha5 selectivity was not increased. The significance of this in regard to occupation of lipophilic regions L-Di vs L-2 in the pharmacophore/receptor model of the BzR is discussed.
