Type 1 cannabinoid receptor (CB1) antagonists have demonstrated promise for the treatment of obesity, liver disease, metabolic syndrome, and dyslipidemias. However, the inhibition of CB1 receptors in the central nervous system can produce adverse effects, including depression, anxiety, and suicidal ideation. Efforts are now underway to produce peripherally restricted CB1 antagonists to circumvent CNS-associated
1型大麻素受体(CB1)拮抗剂已被证明可用于治疗肥胖症,肝脏疾病,代谢综合征和血脂异常。但是,在中枢神经系统中抑制CB1受体会产生不良反应,包括抑郁,焦虑和自杀意念。现在正在努力生产外围受限制的CB1拮抗剂,以规避CNS相关的不良反应。在这项研究中,探索了一系列类似物,其中化合物2的4-氨基哌啶基团被有或没有间隔基的芳基和杂芳基取代的哌嗪基团取代。这导致了人类CB1(hCB1)的温和碱性强效拮抗剂。发现25的2-氯苄基哌嗪很有效(Ki = 8 nM);对hCB1的选择性是对hCB2的> 1000倍;不承担hERG责任;并具有良好的ADME性能,包括高口服吸收和可忽略的CNS渗透性。在酒精诱导的肝脂肪变性的小鼠模型中测试了化合物25,发现它是有效的。总而言之,25代表了令人兴奋的铅化合物,可用于进一步的临床开发或完善。
