Disclosed are a 2,3-dihydrobenzofuran derivative represented by formula (1) or a salt thereof, a method for producing the same, and use thereof:
wherein R1 represents a hydrogen atom or a lower alkyl group; R2 represents a naphthyl group, a pyridyl group, a furyl group or a thienyl group; n is an integer of from 2 to 6; A represents a carbonyl group or a sulfonyl group; and * represents an asymmetric carbon atom.
The 2,3-dihydrobenzofuran derivatives of the present invention and the non-toxic salts thereof have a strong affinity for serotonin 1A receptors. Therefore, are useful as pharmaceutical composition containing the 2,3-dihydrobenzofuran derivatives and the non-toxic salts thereof are especially useful for treating a serotonergic neuron-related disease, such as anxiety, depression, eating disorder, high blood pressure, emesis (including emesis induced by motion sickness, space sickness, dizziness and drug, etc.) and the like.
本发明公开了式(1)代表的2,3-二氢苯并呋喃衍生物或其盐、生产方法及其用途:
其中 R1 代表氢原子或低级烷基;R2 代表萘基、吡啶基、呋喃基或噻吩基;n 为 2 至 6 的整数;A 代表羰基或磺酰基;* 代表不对称碳原子。
本发明的 2,3-二氢苯并呋喃衍生物及其无毒盐对血清素 1A 受体有很强的亲和力。因此,作为含有 2,3-二氢苯并呋喃衍生物及其无毒盐的药物组合物,特别适用于治疗与血清素能神经元有关的疾病,如焦虑、抑郁、饮食失调、高血压、呕吐(包括晕车、晕船、晕眩和药物等引起的呕吐)等。
