  Synthesis and structure–activity relationships of pyrazolodiazepine derivatives as human P2X7 receptor antagonists

  摘要：

  Screening of library compounds has yielded pyrazolodiazepine derivatives with P2X(7) receptor antagonist activity. To explore the structure -activity relationships (SAR) of these pyrazolodiazepines as human P2X(7) receptor antagonists, derivatives were synthesized by substitutions at positions R-2 and R-3 of the pyrazolodiazepine skeleton. Using a 2'(3')-O-(4-benzoylbenzoyl)ATP (BzATP)-induced fluorescent ethidium uptake assay, the activities of these derivatives were tested in HEK-293 cells stably expressing human P2X(7) receptors. Moreover, the effect of these derivatives was assessed by measuring their effect on IL-1 beta release induced by BzATP-induced activation of differentiated THP-1 cells. A 2-phenethyl pyrazolodiazepine derivative with a 1-methyl-1H-3-indolyl group at position R-2 had fivefold greater activity than the derivative with a 5-isoquinolinyl at R-2. Moreover, a benzyl moiety at R-3 had fivefold greater activity than a bicyclic moiety. The stereochemical effect at C-6 showed a preference for the (R)-isomer. Among the series of active derivatives, compound 23b, with a phenethyl group at R-1, a 3-methyl indole at R-2, and a benzyl at R-3, exhibited activity similar to that of the positive control, KN-62, as shown by the inhibitory effects of IL-1 beta release.
