of N-methylbenzamide analogues (2-18) that is structurally derived from SR 48,968, a potent neurokinin-2 (NK(2)) receptor antagonist (pK(b)9.1), has been obtained using asymmetric synthesis. Isothiocyanato-N-methylbenzamide (10-12) and bromoacetamido-N-methylbenzamide derivatives (16-18) have been designed to serve as potential electrophilic affinity labels. Nitro-N-methylbenzamide (4-6) and acetam
已使用不对称合成方法从结构上衍生自SR 48,968(一种有效的神经激肽2(NK(2))受体拮抗剂(pK(b)9.1))的一系列N-甲基苯甲酰胺类似物(2-18)。异硫氰酸根合-N-甲基苯甲酰胺(10-12)和溴乙酰胺基-N-甲基苯甲酰胺衍生物(16-18)已被设计用作潜在的亲电子亲和标记。硝基-N-甲基苯甲酰胺(4-6)和乙酰胺基-N-甲基苯甲酰胺(13-15)被设计用作这些配体的非亲电子对照。使用豚鼠气管的功能测定结果表明,亲电N-甲基苯甲酰胺类似物表现出有效但可克服的NK(2)受体拮抗剂活性。该系列的几个成员(2,3,7-9)表现出有效的NK(2)受体拮抗剂效能,pK(b)值在9.1-9.7范围内。
