  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.

  Syntheses of N10-substituted 7-Arylpyrrolo[2,1-c]-[1,4]benzodiazepine-5,11-diones

  摘要：

  Pyrrolo[2,1‐c][1,4]benzodiazepine‐5,11‐dione and its 7‐bromo derivative were alkylated at the N10 atom applying various methods. The resulting products were subjected to Suzuki–Miyaura reactions using a catalyst system consisting of Pd(Cl)2(PPh3)2 and sodium tert‐butanolate in toluene. Results of an X‐ray single crystal analysis are presented.

  endocannabinoid system (ECS) is of great interest for its therapeutic relevance in several pathophysiological processes. The CB2 subtype is largely localized to immune effectors, including microglia within the central nervous system, where it promotes anti-inflammation. Recently, a rational drug design toward precise modulation of the CB2 active site revealed the novelty of Pyrrolo[2,1-c][1,4]benzodiazepines
