dopaminergic transmission systems. These receptors have been implicated in the CNS system as therapeutic targets in applications such as psychosis, reduction of body weight or Alzheimer's disease. As part of our efforts to develop 5-HT6 antagonists, we explored the benzothiazolone scaffold substituted in position 3 or 6 respectively with ethylamino chains and an aromatic ring connected through a sulfonyl
5-HT 6受体是最近才发现的与胆碱能,谷氨酸能,GABA能和多巴胺能传递系统相互作用的受体。这些受体已经作为诸如精神病,体重减轻或阿尔茨海默氏病的应用中的治疗靶标被牵涉到CNS系统中。作为开发5-HT 6拮抗剂的一部分,我们研究了在3或6位分别被乙氨基链和通过磺酰基接头连接的芳香环取代的苯并噻唑酮骨架。在放射性配体结合试验中评估了最终化合物与5-HT 6相互作用的能力受体。确定了它们对人神经母细胞瘤细胞系SY5Y的潜在细胞毒性作用。它们显示出非常低的细胞毒性,其中之一对5-HT 6受体具有亚微摩尔的亲和力。
