Abstract:
A novel approach to treat hypertension is to interfere with the Renin-Angiotensin system (RAS) by blocking the binding of vasoconstrictive hormone Angiotensin II to the AT(1) receptor site. This approach led to the beneficial drug losartan (COZAAR) and other similar in structure to the antihypertensive drugs (sartans). In an effort to compare the stereoelectronic features of pharmacophoric segments of the different sartans, a research activity was initiated in our laboratory related to the conformational properties of these drugs. In a previous study, the structural features which determine the pharmacophoric segments of losartan were examined. In this study, the conformational properties of eprosartan (TEVETEN), a drug with fewer side effects, were examined. In addition, the superimposition ability of losartan and eprosartan with the peptide antagonist sarmesin was studied.

Aromatic ring substitutions: Substituting the aromatic ring with –OH groups at positions 3 and 4 yields catecholamines (e.g., epinephrine), which have a high affinity for adrenoceptors. Hydrogen bonding between –OH groups and receptors enhances adrenergic activity.
