Comment: Melphalan flufenamide is a peptide-conjugated prodrug of the cytotoxic DNA alkylating drug melphalan [3]. It is highly lipophilic and is rapidly transported into cells where it is quickly hydrolysed by aminopeptidases that are overexpressed by some cancer cells. Melphalan flufenamide is being evaluated as a treatment for multiple myeloma [2,5-6].
The IUPAC Condensed peptide sequence for melphalan flufenamide is H-Phe(Unk)-Phe(4-F)-OEt.

Bioactivity Comments
Melphalan flufenamide's anti-tumour activity is identical to that of melphalan, but is it more selective for tumour cells that overexpress aminopeptidases that the parent drug [3].
