Discovery and development of angiotensin receptor blockers/ja: Difference between revisions

In the early 1980s it was noted that a series of imidazole-5-[[acetic acid]] [[Derivative (chemistry)|derivatives]] diminished blood pressure responses to Ang II in rats. Two compounds, [[S-8307]] and [[S-8308]], were later found to be highly specific and promising non-peptide Ang II receptor antagonists but using [[molecular modeling]] it was seen that their structures would have to [[mimic]] more closely the [[pharmacophore]] of Ang II. Structural modifications were made and the orally active, potent and [[Ligand (biochemistry)#Selective and non-selective|selective]] nonpeptide AT₁ receptor blocker [[losartan]] was developed. In 1995 losartan was approved for clinical use in the United States and since then six additional ARBs have been approved. These drugs are known for their excellent [[Adverse effect (medicine)|side-effects]] profiles, which [[clinical trials]] have shown to be similar to those of [[placebos]].
