| Description | Melphalan, 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 which is used for the palliative treatment of multiple myeloma and for the palliation of non-resectable epithelial carcinoma of the ovary. has also been used alone or as part of various chemotherapeutic regimens as an adjunct to surgery in the treatment of breast cancer, alone or in combination regimens for palliative treatment of locally recurrent or unresectable in-transit metastatic melanoma of the extremities, as well as for the treatment of amyloidosis with prednisone. 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. |
