Metabolite Identification
Common NameMelphalan
DescriptionMelphalan, also known as L-sarcolysine or L-PAM, belongs to the class of organic compounds known as phenylalanine and derivatives. Phenylalanine and derivatives are compounds containing phenylalanine or a derivative thereof resulting from reaction of phenylalanine at the amino group or the carboxy group, or from the replacement of any hydrogen of glycine by a heteroatom. Melphalan is a drug. Melphalan is a very strong basic compound (based on its pKa). Melphalan is formally rated as a carcinogen (by IARC 1) and is also a potentially toxic compound. A phenylalanine derivative comprising L-phenylalanine having [bis(2-chloroethyl)amino group at the 4-position on the phenyl ring.
