Synthesis and pharmacological evaluation of 11-(1,6-dimethyl-1,2,3,6-tetrahydropyridin-4-yl)-5H-dibenzo[b,e][1,4]diazepines with clozapine-like receptor occupancy at dopamine D1/D2 receptor
Clozapine-like compound without agranulocytosis risk is need to cure the treatment resistant schizophrenia (TRS). We discovered (S)-3 as Clozapine-like dopamine D2/D1 receptor selectivity and improved reactive metabolites formation profile by the modification of piperazine moiety in Clozapine. The optimization of (S)-3 gave compound 5 to be best compound (approximately 10-fold stronger affinity for
无粒细胞缺乏症风险的氯氮平样化合物是治疗耐药性精神分裂症(TRS)的需要。我们发现(S)-3为氯氮平样多巴胺D 2 / D 1受体选择性,并通过氯氮平中哌嗪部分的修饰改善了反应性代谢产物的形成。(S)-3的优化使化合物5成为最佳化合物(对D 2 / D 1受体的亲和力约为10倍,并且与氯氮平的选择性D 2 / D 1的选择性相似)。类氯氮平D 2 / D 1通过体内评估证明了受体的占用情况。此外,化合物5的反应性代谢物引起的粒细胞缺乏症的风险被认为低于氯氮平。正在研究化合物5的药理学细节,以开发其用于TRS治疗。
