APPLICATIONS |
||
| L-Homophenylalanine is an intermediate for the synthesis of ACE-inhibitors (angiotensin-converting enzyme inhibitor) such as lisinopril to treat hypertension (high blood pressure and heart failure). It is also used for the synthesis of NEPA [(S,S)-N-(1-Ethoxycarbonyl-3-phenylpropyl)alanine] which is a key intermediate to produce ACE-inhibitors such as Enalapril, Delapril, Quinapril, Ramipril. | ||

| OTHER INFORMATION | ||
| In chemical, the prefix homo- indicates the addition of one methyl(CH2) group to the main skeleton. Phenylalanine is an essential amino acid obtained in the levo form by hydrolysis of proteins (as lactalbumin). Branched amino-acids (Valine, Isoleucine and Leucine ) with tryptophan and phenylalanine (aromatic side chain amino acids) contribute to the structure of protein by the tendency of its side chain composed only of carbon and hydrogen to participate in hydrophobic interactions which determines the tertiary structure of the peptide chain. In addition to its role in protein synthesis, it is the metabolic precursor of the non-essential amino acid tyrosine which makes hormones, such as norepinephrine and epinephrine in the normal body. The prefix nor- describes normal structure which has no branched chain of carbon atoms. But in case of norepinephrine, it has one less methylene group than its homologue, epinephrine. Phenylalanine is also converted to phenylethylamine occuring naturally in the brain to elevate mood. It is used to treat depression, inflammation, chronic pain, Parkinson's disease. Phenylalanine is a key intermediate to make aspartame. | ||
