Perindopril arginine

Perindopril arginine has the chemical name, L-arginine (2S,3aS,7aS)- 1-[(2S)- 2-[[(1S)- 1-(ethoxycarbonyl)butyl]amino] propanoyl]octahydro-1H-indole-2-carboxylate. It is a dipeptide monoacid monoester with a perhydroindole group and no sulfydryl radical. Perindopril arginine is a white powder, readily soluble in purified water, slightly soluble in 95% ethanol and practically insoluble in chloroform. Perindopril has five asymmetric centres. The drug is synthesised stereoselectively so that it is a single enantiomer (all S stereochemistry).

Amlodipine besilate

Amlodipine besilate is a dihydropyridine derivative, and has the following chemical name: 3-Ethyl 5-methyl (4RS)- 2-[(2-aminoethoxy)methyl]- 4-(2-chorophenyl)- 6-methyl-1,4-dihydropyridine-3,5-dicarboxylate benzenesulfonate. Amlodipine besilate is chiral and present as a racemate. It is a white crystalline powder and is slightly soluble in water and sparingly soluble in ethanol.
