A series of novel angiotensin II type 1 receptor antagonists were prepared. Radioligand binding assay suggested that compounds 1b and 1c could be recognized by the AT1 receptor with an IC50 value of 1.6 ± 0.09 nM and 2.64 ± 0.7 nM, respectively. In vivo anti-hypertension experiments showed that compounds (1a, 1b, 1c, 1e) elicited a significant decrease in SBP and DBP of spontaneous hypertensive rats
制备了一系列新型的血管紧张素II 1型受体拮抗剂。放射性配体结合试验表明,化合物1b和1c可以被AT 1受体识别,IC 50值分别为1.6±0.09 nM和2.64±0.7 nM。体内抗高血压实验表明,化合物(1a,1b,1c,1e)引起自发性高血压大鼠(SHRs)的SBP和DBP显着降低。降压作用维持10小时,这表明这些化合物具有良好的降血压作用。急性毒性试验表明该化合物的LD 50值1b为2316.8 mg / kg,低于缬沙坦(LD 50 = 307.50 mg / kg),但高于氯沙坦(LD 50 = 2248 mg / kg)。因此,它们可以被认为是新型的抗高血压药物,值得进一步研究。
