  • Synthesis and Biological Studies of a Novel CB1 Antagonist

    This paper describes the synthesis, early process development, salt selection strategies and pre clinical evaluation of novel, potent and selective CB1 antagonist, 8-Chloro-1-(2,4-dichloro-phenyl)-4,5-dihydro-1H-6-oxa-1,2-diaza-benzo[e]azulene-3-carboxylic acid piperidin-1-ylamide 1. The CB1 antagonism of compound 1 is also confirmed by reversal of CB1 agonist-induced hypothermia in Swiss albino mice. The process for the preparation of the compound 1 as a crystalline solid is also described. The crystalline form of the compound is found to be low bioavailable, therefore attempts have been made to improve its bioavailability through polymorphic transformation and salt formation. None of the salts prepared were found to be suitable for further development. The amorphous form of the compound 1 is found to be better suited. In vivo efficacy study of the amorphous form of compound 1 in 5% sucrose solution intake model in female Zucker fa/fa rats at single oral dose of 10 mg/kg demonstrates better reduction in the sucrose solution consumption than the corresponding crystalline form. The plasma concentration Cmax at AUC exposure of the amorphous form of the compound 1 is significantly improved and better than the Cmax of the corresponding crystalline form of the compound 1. On the basis of the efficacy, pharmacokinetic and toxicological evaluations, the compound 1 in the amorphous form is selected as a pre-clinical lead candidate.
    本文描述了一种新型、强效且选择性CB1拮抗剂8-氯-1-(2,4-二氯苯)-4,5-二氢-1H-6-氧杂-1,2-二氮杂苯[e]吖啶-3-羧酸哌啶-1-酰胺1的合成、早期工艺开发、盐选择策略和临床前评估。化合物1的CB1拮抗作用通过逆转瑞士铝白鼠CB1激动剂诱导的体温降低得到了证实。还描述了制备化合物1为结晶固体的工艺。发现该化合物的结晶形式生物利用度较低,因此尝试通过多晶型转化和盐的形成来提高其生物利用度。然而,所制备的盐均未找到适合进一步开发的候选者。化合物1的无定形形式被认为更适合。在5%蔗糖溶液摄入模型中,对雌性Zucker fa/fa大鼠进行的无定形形式化合物1的口服单剂量10 mg/kg的体内有效性研究显示出与相应的结晶形式相比,蔗糖溶液摄入量显著减少。无定形形式的化合物1的血浆浓度Cmax在AUC暴露下显著改善,并且优于相应结晶形式的Cmax。基于有效性、药代动力学和毒理学评估,无定形形式的化合物1被选定为临床前的主要候选药物。
