New melphalan derivatives for the treatment of retinoblastoma in combination with thermotherapy.

ABSTRACT: Of the different modalities used to treat retinoblastoma, a chemothermotherapeutic regimen combining carboplatin and thermotherapy (also termed focal therapy), and the application of melphalan as a monotherapy, are particularly successful. Some studies indicate that melphalan shows potential when applied in combination with focal therapy, and yet is not applied in this combination. Here we describe a series of synthetically modified melphalan derivatives that display enhanced cytotoxicity relative to melphalan itself, with some displaying further enhancements in cytotoxicity when applied in combination with heat (used as a model for thermotherapy). The synthetic approach, which involves modifying melphalan with perfluorous chains of varying lengths via an ester linker, could lead to a more effective treatment option for retinoblastoma with reduced side-effects, which is a key limitation of melphalan.
