Patent AT-E400300-T1: [Translated] POLYAMINE-METAL CHELATING CONJUGATES

Many metal chelators have polar or charged functional groups, which render them difficult to transport across a cell membrane. Polyamine-metal chelator conjugates of the invention are compounds comprising a first moiety which is a metal chelator and a second moiety which is a polyamine, where the polyamine moiety includes three or more nitrogen atoms which are capable of being positively charged at physiological pH. A spermine-L1 conjugate has been shown to accumulate in L1210 cells several hundred fold more than the unconjugated L1 chelator.
