The present invention identifies a compound which binds to the PAH1 domain of mSin3B that specifically binds to neural restrictive silencer factor NRSF, and uses the compound as a prophylactic and/or a therapeutic for diseases associated with abnormal expression of neural restrictive silencer factor NRSF/REST or abnormal expression of genes targeted by NRSF/REST, such as Huntington's disease, medulloblastoma and neuropathic pain.
The present invention provides a pharmaceutical composition comprising a substance capable of binding to the PAH1 domain of mSin3B, e.g., a compound represented by the following formula (I), a pharmacologically acceptable salt thereof, or a pharmacologically acceptable ester thereof:
wherein n represents 0 or 1; R1, R2, R3, R4 and R5 each independently represent a hydrogen atom, a hydrocarbon group or a functional group; Y represents a single bond, a carbonyl group, -CONH-, -NHCO- or a sulfonyl group; and Z represents a nitrogen-containing heterocyclic group which may have a substituent, an amino group which may have a hydrocarbon group or an aromatic hydrocarbon group, or a nitrogen and oxygen-containing heterocyclic group which may have a substituent.
本发明确定了一种能与mSin3B的PAH1结构域结合的化合物,该化合物能特异性地与神经限制性沉默因子NRSF结合,并将该化合物用作预防和/或治疗与神经限制性沉默因子NRSF/REST异常表达或NRSF/REST靶向基因异常表达相关的疾病,如亨廷顿氏病、髓母细胞瘤和神经性疼痛。
本发明提供了一种药物组合物,该药物组合物包含一种能够与 mSin3B 的 PAH1 结构域结合的物质,例如由下式(I)代表的化合物、其药理学上可接受的盐或其药理学上可接受的酯:
其中 n 代表 0 或 1;R1、R2、R3、R4 和 R5 各自独立地代表氢原子、烃基或官能团;Y 代表单键、羰基、-CONH-、-NHCO- 或磺酰基;Z 代表可能具有取代基的含氮杂环基、可能具有烃基或芳香烃基的氨基或可能具有取代基的含氮和氧杂环基。
