The present invention discloses a compound of formula (I): wherein: R1 is an aryl or heteroaryl ring; R2 is hydroxy, C1-6 alkoxy, C1-6 alkyl, amino, NR′R″ or C1-6 alkyl-NR′R″ where R′ and R″ are independently chosen from hydrogen and C1-4 alkyl and where R′ and R″, together with the nitrogen atom to which they are attached, form a saturated nitrogen-containing 3-7 membered heterocycle optionally containing a further nitrogen atom and optionally substituted by NR′R″ as defined above or R2 is C1-6 alkoxy substituted by NR′R″ as defined above; R3 is hydrogen or C1-6 alkyl; R4 is hydrogen, C1-8 alkyl, C2-8 alkenyl, C2-8 alkynyl, C3-8 cycloalkyl, aryl or aryl C1-6 alkyl; R5 is hydrogen, C1-8 alkyl, C2-8 alkenyl, C2-8 alkynyl, C3-8 cycloalkyl, aryl, aryl C1-6 alkyl or C1-6 alkoxycarbonyl; or R4 and R5, together with the nitrogen atom to which they are attached, form a C3-C10 mono- or bicyclic saturated ring; X and Y are independently chosen from hydrogen, hydroxy, nitro, amino, cyano, CF3, halogen and C1-4 alkyl; or a pharmaceutically acceptable salt thereof; as NK-2/NK-3 ligands for treating schizophrenia, COPD, asthma or irritable bowel syndrome.
本发明揭示了化合物(I)的结构:其中:R1是芳基或杂环芳基环;R2是羟基,C1-6烷氧基,C1-6烷基,
氨基,NR′R″或C1-6烷基-NR′R″,其中R′和R″分别选择氢和C1-4烷基,R′和R″与它们所连接的氮原子一起形成一个饱和的含氮3-7环杂环,该杂环可选择性地含有进一步的氮原子,并可选择性地被上述定义的NR′R″取代,或者R2是被上述定义的NR′R″取代的C1-6烷氧基;R3是氢或C1-6烷基;R4是氢,C1-8烷基,C2-8烯基,C2-8炔基,C3-8环烷基,芳基或芳基C1-6烷基;R5是氢,C1-8烷基,C2-8烯基,C2-8炔基,C3-8环烷基,芳基,芳基C1-6烷基或C1-6烷氧羰基;或者R4和R5,与它们所连接的氮原子一起,形成C3-C10单环或双环饱和环;X和Y分别选择自氢,羟基,硝基,
氨基,
氰基,
CF3,卤素和C1-4烷基;或其药学上可接受的盐;作为NK-2/NK-3
配体,用于治疗精神分裂症,慢性阻塞性肺疾病,哮喘或肠易激综合症。
