A substituted benzimidazole and benzindazole derivatives had been synthesized having antihypertensive activity through antagonizing the angiotensin II (Ang II) receptors. The in vivo antihypertensive activity of the compounds was done with acute renal hypertension model. Two compounds TG 1 and TG 3 were found to have antihypertensive activity comparable to Telmisartan which is a prototype for Angiotensin II receptor antagonists class of drugs.In an antihypertensive study the compounds TG 1, TG 2 and TG 3 had systolic blood pressures of 147.2 mm/Hg, 168.2 mm/Hg, and 126.3 mm/Hg, respectively. This systolic blood pressure was lower than the disease control vehicle-treated rodents, which had a systolic blood pressure of 167.2 mm/Hg. The diastolic blood pressure was 119.7 mm/Hg, 124.7 mm/Hg and 88.83 mm/Hg, respectively and that of the disease control vehicle-treated rodents was 122.3 mm/Hg. TG 3 had comparable decrease in the MABP to Telmisartan. These encouraging results make compound TG 3 effective anti-hypertensive drug candidate and worthy of further investigation.
一种取代的苯并咪唑和苯并噻唑衍生物已被合成,并通过拮抗血管紧张素II(Ang II)受体展现了抗高血压活性。该化合物的体内抗高血压活性是在急性肾高血压模型中进行的。两种化合物TG 1和TG 3的抗高血压活性与血管紧张素II受体拮抗剂类药物的原型——替米沙坦相当。在抗高血压研究中,化合物TG 1、TG 2和TG 3的收缩压分别为147.2 mm/Hg、168.2 mm/Hg和126.3 mm/Hg。这些收缩压低于疾病对照车辆处理的啮齿动物,其收缩压为167.2 mm/Hg。舒张压分别为119.7 mm/Hg、124.7 mm/Hg和88.83 mm/Hg,而疾病对照车辆处理的啮齿动物的舒张压为122.3 mm/Hg。TG 3在平均动脉血压(MABP)下降方面与替米沙坦相当。这些令人鼓舞的结果使TG 3成为有效的抗高血压药物候选者,值得进一步研究。
