Molecular design, synthesis, in vitro and in vivo studies of novel derivatives of indole-3-carboxylic acid new series of angiotensin II receptor 1 antagonists is presented. Radioligand binding studies using [125I]-angiotensin II displayed that new derivatives of indole-3-carboxylic acid have a high nanomolar affinity for the angiotensin II receptor (AT1 subtype) on a par with the known pharmaceuticals such as losartan. Biological studies of synthesized compounds in spontaneously hypertensive rats have demonstrated that compounds can lower blood pressure when administered orally. Maximum the decrease in blood pressure was 48 mm Hg with oral administration of 10 mg/kg and antihypertensive effect was observed for 24 h, which is superior to losartan.

UI MeSH Term Description Entries
D006973 Hypertension Persistently high systemic arterial BLOOD PRESSURE. Based on multiple readings (BLOOD PRESSURE DETERMINATION), hypertension is currently defined as when SYSTOLIC PRESSURE is consistently greater than 140 mm Hg or when DIASTOLIC PRESSURE is consistently 90 mm Hg or more.

D000804 Angiotensin II An octapeptide that is a potent but labile vasoconstrictor. It is produced from angiotensin I after the removal of two amino acids at the C-terminal by ANGIOTENSIN CONVERTING ENZYME. The amino acid in position 5 varies in different species. To block VASOCONSTRICTION and HYPERTENSION effect of angiotensin II, patients are often treated with ACE INHIBITORS or with ANGIOTENSIN II TYPE 1 RECEPTOR BLOCKERS.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
