Angiotensin converting enzyme (ACE) catalyses the conversion of angiotensin I to angiotensin II a potent vasoconstrictor in a substrate concentration dependent manner and degrades bradykinin a potent vasodilator and other vasoactive peptides which leads to increase in blood pressure. Prolonged increase in blood pressure condition increases the risk of heart attacks, heart failure, and stroke or kidney failure. Naturally occurring proteins acts as angiotensin converting enzyme inhibitors. Inhibition of ACE by angiotensin converting enzyme inhibitors results in the decreased of formation of angiotensin II and decreased metabolism of bradykinin leading to systematic dilation o f the arteries and veins and a decrease in arterial blood pressure. The molecular docking analysis done indicates that the receptor of human angiotensin converting enzyme through an interaction with the chemical bonds .Herbal drugs were safe and milder with few or no side effects than the drugs currently used in the treatment lessening high blood pressure which can be better used for the development of new therapeutics to decrease the formation of angiotensin II and to decrease the activation of bradykinin. The target of this insilico analysis was to study the ability of the secondary metabolites of Trigonella foenum graecum(TFG) to serve as antagonist to angiotensin converting enzyme (ACE).
