  Synthesis and biological evaluation of new 6-hydroxypyridazinone benzisoxazoles: Potential multi-receptor-targeting atypical antipsychotics

  摘要：

  In recent years, multi-targeting directed ligands have attracted great interest as possible new atypical antipsychotics. Combinations of dopamine and serotonin receptor ligands within single molecules might afford new therapeutic opportunities. Herein, we describe the synthesis of a novel series of 6-hydroxypyridazinone benzisoxazoles and their binding behaviors to different receptors in terms of atypical antipsychotic behaviors. The most potent compound (46) exhibited excellent affinities for certain receptors (D-2, K-i = 0.5 +/- 0.07 nM; 5-HT1A, K-i = 5.9 +/- 0.8 nM; 5-HT2A, K-i = 0.3 +/- 0.01 nM; 5-HT6, K-i = 0.5 +/- 0.04 nM) and combined with low affinities for the H-1, 5-HT2C, and adrenergic alpha(1) receptors. In contrast to risperidone, compound 46 exhibited a high cataleptic threshold; this may be useful in the development of a novel class of drugs treating schizophrenia. (C) 2016 Elsevier Masson SAS.

  A novel Rh(III)-catalyzed annulation of phthalazinones or pyridazinones with various allenes was developed, leading to the formation of indazole derivatives bearing a quaternary carbon in moderate to good yields. The targeted products were synthesized via sequential C–H activation and olefin insertion, followed by β-hydride elimination and intramolecular cyclization. The synthetic protocol proceeded

  In recent years, multi-targeting directed ligands have attracted great interest as possible new atypical antipsychotics. Combinations of dopamine and serotonin receptor ligands within single molecules might afford new therapeutic opportunities. Herein, we describe the synthesis of a novel series of 6-hydroxypyridazinone benzisoxazoles and their binding behaviors to different receptors in terms of atypical antipsychotic behaviors. The most potent compound (46) exhibited excellent affinities for certain receptors (D-2, K-i = 0.5 +/- 0.07 nM; 5-HT1A, K-i = 5.9 +/- 0.8 nM; 5-HT2A, K-i = 0.3 +/- 0.01 nM; 5-HT6, K-i = 0.5 +/- 0.04 nM) and combined with low affinities for the H-1, 5-HT2C, and adrenergic alpha(1) receptors. In contrast to risperidone, compound 46 exhibited a high cataleptic threshold; this may be useful in the development of a novel class of drugs treating schizophrenia. (C) 2016 Elsevier Masson SAS.
