MedKoo CAT#: 100580

CAS#: 3223-07-2 (HCl)

Description: Melphalan is an orally available phenylalanine derivative of nitrogen mustard with antineoplastic activity. Melphalan alkylates DNA at the N7 position of guanine and induces DNA inter-strand cross-linkages, resulting in the inhibition of DNA and RNA synthesis and cytotoxicity against both dividing and non-dividing tumor cells.

More Info: M elphalan  is used to treat multiple myeloma and ovarian cancer, and occasionally malignant melanoma. The agent was first investigated as a possible drug for use in melanoma. It was not found to be effective, but has been found to be effective in the treatment of myeloma. Adminstration: oral or intravenous; dosing varies by purpose and route of administration as well as patient weight.   DRUG DESCRIPTION Melphalan, also known as L-phenylalanine mustard, phenylalanine mustard, L-PAM, or L-sarcolysin, is a phenylalanine derivative of nitrogen mustard. Melphalan is a bifunctional alkylating agent that is active against selected human neoplastic diseases. It is known chemically as 4-[bis(2-chloroethyl)amino]-L-phenylalanine. The molecular formula is C13H18Cl2N2O2 and the molecular weight is 305.20. Melphalan is the active L-isomer of the compound and was first synthesized in 1953 by Bergel and Stock; the D-isomer, known as medphalan, is less active against certain animal tumors, and the dose needed to produce effects on chromosomes is larger than that required with the L-isomer. The racemic (DL-) form is known as merphalan or sarcolysin. Melphalan is practically insoluble in water and has a pKa1 of ~2.5. ALKERAN for Injection is supplied as a sterile, nonpyrogenic, freeze-dried powder. Each single-use vial contains melphalan hydrochloride equivalent to 50 mg melphalan and 20 mg povidone. ALKERAN for Injection is reconstituted using the sterile diluent provided. Each vial of sterile diluent contains sodium citrate 0.2 g, propylene glycol 6.0 mL, ethanol (96%) 0.52 mL, and Water for Injection to a total of 10 mL. ALKERAN for Injection is administered intravenously.

Biological target: Melphalan is an orally available phenylalanine derivative of nitrogen mustard with antineoplastic activity.
In vitro activity: The ability of conjugates of melphalan and FSHβ peptides to kill murine testicular cells was first tested in vitro in a three-dimensional testicular cell coculture system. In this system, melphalan caused considerable cell death as measured both by increases in lactate dehydrogenase concentrations in the culture supernatant and direct visualization of the cultures. Of the conjugates tested, melphalan conjugated to a 20-amino acid peptide derived from human FSHβ consisting of amino acids 33 to 53 (FSHβ (33-53)-melphalan) was very potent, with cell cytotoxicity and lactate dehydrogenase release roughly one-half that of melphalan.

In vivo activity: Male Wistar rats were treated with 4-8 mg/kg melphalan intravenously. Melphalan 5 mg/kg caused self-limiting intestinal injury, severe neutropenia and fever while impairing the microbial metabolome, prompting expansion of enteric pathogens.
