Preparation of Highly Potent and Selective Non-Peptide Antagonists of the Arginine Vasopressin V1A Receptor by Introduction of a 2-Ethyl-1H-1-imidazolyl Group
our efforts to develop a novel class of selective V(1A) receptorantagonists, the N-methylbenzanilide structure was applied to a 4,4-difluoro-1-benzazepine derivative, 4, which is a selective V(1A) receptorantagonist. Further structural modifications gave 16a with high V(1A) affinity and V(2)/V(1A) selectivity (K(i)=5.71 nM, V(2)/V(1A)=140) and potent V(1A) receptorantagonist activity (ID(50)=0.0080
在我们努力开发一类新型的选择性V(1A)受体拮抗剂的过程中,将N-甲基苯甲腈结构应用于4,4-二氟-1-苯并enza庚因衍生物4,这是一种选择性V(1A)受体拮抗剂。进一步的结构修饰使16a具有高V(1A)亲和力和V(2)/ V(1A)选择性(K(i)= 5.71 nM,V(2)/ V(1A)= 140)和有效V(1A)受体拮抗剂活性(ID(50)= 0.0080mg / kg iv)。
