HIDE SMILES / InChI
Melphalan flufenamide ethyl ester (melflufen, previously denoted J1) is a peptidase-potentiated dipeptide prodrug of alkylating agent melphalan. Melflufen readily penetrates membranes and an equilibrium is rapidly achieved, followed by enzymatic cleavage in aminopeptidase positive cells, which results in trapping of less lipophilic metabolites. This targeting effect results in very high intracellular concentrations of its metabolite melphalan and subsequent apoptotic cell death. This results in a potency increase (melflufen vs melphalan) ranging from 10- to several 100-fold in different in vitro models. Melflufen triggers a rapid, robust, and an irreversible DNA damage which may account for its ability to overcome melphalan-resistance in multiple myeloma cells. Melflufen has been granted orphan drug designation for the treatment of multiple myeloma.

Sample Use Guides

Phase 3 clinical study (OCEAN, OP-103). Melflufen 40 mg i.v. on Day 1 and dexamethasone 40 mg on Days 1, 8, 15 and 22 of each 28-day cycle.
Route of Administration: Intravenous
Melflufen showed activity with cytotoxic IC50-values in the submicromolar range (0.011-0.92 μM) in the cell lines. In the primary cultures melflufen yielded slightly lower IC50-values (2.7 nM to 0.55 μM). Treated cell lines exhibited a clear accumulation in the G2/M-phase of the cell cycle.
