agents are unlikely to prolong the survival of patients and often associated with systemic side effects. The bone targeting drug delivery via systemic administration may provide both better treatment efficacy and less frequent administration. In this study, we describe the synthesis, in vitro and in vivo evaluation of novel melphalan-bisphosphonate hybrids, with a tumor microenvironment sensitive linkage
