The invention provides a conjugate comprising (i) a selectivity agent which binds specifically to one or more neurotransmitter transporters selected from the group consisting of a dopamine transporter (DAT), serotonin transporter (SERT) or a norepinephrine transporter (NET) and (ii) a nucleic acid capable of specifically binding to a target molecule which is expressed in the same cell as the neurotransmitter transporter wherein said target molecule is α-synuclein or the mRNA encoding α-synuclein. The conjugates of the present invention are useful for the delivery of the nucleic acid to a cell of interest and thus, for the treatment of diseases which require a down-regulation of the protein encoded by the target nucleic acid as well as for the delivery of imaging agents to the cells for diagnostic purposes.
本发明提供了一种共轭物,该共轭物包含:(i) 一种选择性制剂,它能与一种或多种神经递质转运体特异性结合,这些神经递质转运体选自由多巴胺转运体(DAT)、5-羟色胺转运体(SERT)或去甲肾上腺素转运体(NET)组成的组、多巴胺转运体 (DAT)、5-羟色胺转运体 (SERT) 或去甲肾上腺素转运体 (NET);(ii) 能够与靶分子特异性结合的核酸,该靶分子与神经递质转运体在同一细胞中表达,其中所述靶分子为 α-突触核蛋白或编码 α-突触核蛋白的 mRNA。本发明的共轭物可用于将核酸递送至相关细胞,从而治疗需要下调靶核酸编码蛋白的疾病,也可用于将成像剂递送至细胞以进行诊断。
