The chemical formula of is (C39)(H54)(N6)(O8)S and the molecular weight is 766.94 g/mol.There are 5 aromatic rings, two of which are heterocyclic. One hydroxyl group near the center of the compound that plays an important role in active site binding. The amino groups cause the protease to recognize the drug as a natural substrate with amino acid groups which are recognized by the active sites.
Protein and Drug interationsProtein and Drug interations
intermolecular forces that cause the drug to bind in the active site of the protease are prodominantly H-bonds to . The carboxylic acid group in the residue 25 binds with the hydroxyl group of Saquinavir.
