Melflufen hydrochloride

Melflufen (Melphalan flufenamide) hydrochloride, a dipeptide prodrug of Melphalan, is an alkylating agent. Melflufen hydrochloride shows antitumor activity against multiple myeloma (MM) cells and inhibits angiogenesis. Melflufen hydrochloride induces irreversible DNA damage and cytotoxicity in MM cells[1][2].

Melflufen (Melphalan flufenamide) hydrochloride (0.5-10 μM; 24 hours) decreases viability of MM.1S, INA-6, RPMI-8226, MM.1R, Dox-40, ARP-1, and ANBL-6 cells in a concentration-dependent manner[1]. Melflufen hydrochloride induces apoptosis in MM.1S cells[1]. Cell Viability Assay[1] Cell Line: Multiple myeloma cells: MM.1S, INA-6, RPMI-8226, MM.1R, Dox-40, ARP-1, ANBL-6 cells Concentration: 0.5, 1, 3, 5, 10 μM Incubation Time: 24 hours Result: A significant concentration-dependent decrease in viability of all cell lines was observed.

Melflufen (Melphalan flufenamide) hydrochloride (3 mg/kg; i.v.; twice-weekly for two weeks) shows anti-MM activity in xenograft mouse model[1]. Animal Model: CB-17 SCID mice (human plasmacytoma MM.1S xenograft mouse model)[1] Dosage: 3 mg/kg Administration: 1.v.; twice-weekly for two weeks Result: Significantly inhibited MM tumor growth and prolonged survival of mice.
