ACE is an important drug target in the treatment of vesicular diseses. ACE is primarily known for its ability to cleave Angiotensin -I to the vasoactive octa peptide Angiotensin-II, but is also able to cleave a number of other substrates including the vasodilator a physiological modulator of hematopoiesis. In present study virtual screening of Alangium salvifolium phytocompounds act as Angiotensin-I inhibitor and assess its molecular basis of inhibition. The present research computationally emphases to Angiotensin-I protein receptor with four Alangium phytocompounds, using molecular docking and simulation studies. From the results showed the interactions be?tween 4YAY (Angiotensin-I) receptor protein with A. salvifolium phytocompounds, a alangum1(Alangium-1(4(benzoyloxy)methyl-2hydroxyphenoxy tetrahydorxy hexoxone 1,2,3,4,5, pentaium ) showed the best glide docking XP score -8.5 kcal/mol binding energy value with best fit simulation study .. Based on the result, the Alangium-1 and target were run on MD simulations stable at 10 ns. Finally, this study concludes the Alangium-1 is a more suitable drug for vesicular remodeling by blocking Angiotensin signaling cascade.
