| L-Homophenylalanine Usage And Synthesis |
| Description | L-Homophenylalanine is an amino acid derivative. It has been extensively used in the pharmaceutical industry as a precursor for production of angiotensin-converting enzyme (ACE) inhibitor: enalapril, delapril, quinapril and ramipril, which possesses significant clinical application in the management of hypertension and congestive heart failure (CHF). It acts as an anti-tumor reagent.

| | Chemical Properties | White Solid | | Uses | Antitumor agent. | | Uses | L-Homophenylalanine is used as a precursor in the pharmaceutical industry for the production of angiotensin-converting enzyme (ACE) and R-(-)-Homophenylalanin-ethylester. It is also involved in the synthesis of NEPA [(S,S)-N-(1-Ethoxycarbonyl-3-phenylpropyl)alanine], which is a key intermediate to prepare the ACE-inhibitors: enalapril, delapril, quinapril and ramipril. It acts as an anti-tumor reagent. | | Definition | ChEBI: A non-proteinogenic L-alpha-amino acid that is an analogue of L-phenylalanine having a 2-phenylethyl rather than a benzyl side-chain. |
