Curator's Comment: description was created based on several sources, including,http://www.nhs.uk/ipgmedia/National/Macmillan%20Cancer%20Support/assets/MelphalanMCS5pages.pdf http://www.bloodjournal.org/content/bloodjournal/100/1/224.full.pdf

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 which produces a number of DNA adducts with the DNA interstrand crosslink (ICL) considered to be the critical cytotoxic lesion. Melphalan is used to treat different cancers including myeloma, melanoma and ovarian cancer.

Sample Use Guides

In Vivo Use Guide

Relapsed or refractory multiple myeloma: recommended dosage of PEPAXTO is 40 mg intravenously over 30 minutes on Day 1 of each 28-day treatment cycle, in combination with dexamethasone.

Route of Administration: Intravenous

In Vitro Use Guide

Melflufen showed activity with cytotoxic IC50-values in the submicromolar range (0.011-0.92 uM) in the cell lines. In the primary cultures melflufen yielded slightly lower IC50-values (2.7 nM to 0.55 uM). Treated cell lines exhibited a clear accumulation in the G2/M-phase of the cell cycle.
