  • Novel compositions magnetic particles covered with gem-bisphosphonate derivatives
    Publication number: 20100297025
    Abstract: The invention relates to a composition comprising acid magnetic particles (p) based on an iron compound, the acid magnetic particles (p) being complexed by one or more gem-bisphosphonate compounds, of formula I: X-L-CH(PO3H2)2 ??(I) in which: L represents an organic group connecting the X group to the gem-bisphosphonate group —CH(PO3H2)2; X represents a chemical group capable of reacting with a biovector; all or some of the X groups of the particles optionally being coupled to a biovector. The invention relates also to a process for the preparation of the compositions and their use, in particular as contrast products for Magnetic Resonance Imaging (MRI).
    Type: Application
