A novel class of potent and selective non-peptide neurokinin-3 (NK-3) receptor antagonists, featuring the 4-quinolinecarboxamide framework, has been designed based upon chemically diverse NK-1 receptor antagonists. The novel compounds 33-76, prompted by chemical modifications of the prototype 4, have been characterized by binding analysis using a membrane preparation of chinese hamster ovary (CHO)
基于化学上不同的NK-1受体拮抗剂,设计了一种新型的有效且选择性的非肽神经激肽3(NK-3)受体拮抗剂,其特征在于4-喹啉羧酰胺骨架。通过原型4的化学修饰促进了新型化合物33-76的表达,其特征在于使用表达人神经激肽3受体(hNK-3-CHO)的中国仓鼠卵巢(CHO)细胞膜制剂进行结合分析,并建立了明确的结构-活性关系(SAR)。从SARs(R)-N- [α-(甲氧基羰基)苄基] -2-苯基喹啉-4-羧酰胺(65,SB 218795,hNK-3-CHO结合Ki = 13 nM)出现,是最有效的化合物之一这个新颖的班级。对其他神经激肽受体(hNK-2-CHO和hNK-1-CHO)的选择性研究表明,对hNK-3的选择性是对hNK-2受体的65倍(hNK-2-CHO结合Ki = 1221 nM)。相对于hNK-1受体具有超过7000倍的选择性(hNK-1-CHO结合Ki => 100 micro
