NUCLEOSIDE DIPHOSPHATE OR DIPHOSPHONATE PRODRUGS, OR NUCLEOSIDE ANALOGUE DIPHOSPHATE OR DIPHOSPHONATE PRODRUGS,NUKLEOSID-DIPHOSPHAT- ODER DIPHOSPHONAT-PRODRUGS ODER NUKLEOSID-ANALOG-DIPHOSPHAT- ODER DIPHOSPHONAT-PRODRUGS

The invention provides a nucleoside diphosphate or nucleoside diphosphonate prodrug or a nucleoside analogue diphosphate or nucleoside analogue diphosphonate prodrug, or a pharmaceutically acceptable salt thereof, having two covalently bound lipophilic moieties A and B at the terminal phosphate group, phosphonate group or analogous phosphorus-containing group, wherein the lipophilic moieties A and B are both non-bioreversible.
