    摘要： Prodrugs of formula I, their uses, their intermediates, and their method of manufacture are described: wherein: V, W, and W′ are independently selected from the group consisting of —H, alkyl, aralkyl, alicyclic, aryl, substituted aryl, heteroaryl, substituted heteroaryl, 1-alkenyl, and 1-alkynyl; or together V and Z are connected via an additional 3-5 atoms to form a cyclic group containing 5-7 atoms, optionally 1 heteroatom, substituted with hydroxy, acyloxy, alkoxycarbonyloxy, or aryloxycarbonyloxy attached to a carbon atom that is three atoms from both O groups attached to the phosphorus; or together V and Z are connected via an additional 3-5 atoms to form a cyclic group, optionally containing 1 heteroatom, that is fused to an aryl group at the beta and gamma position to the O attached to the phosphorus; together V and W are connected via an additional 3 carbon atoms to form an optionally substituted cyclic group containing 6 carbon atoms and substituted with one substituent selected from the group consisting of hydroxy, acyloxy, alkoxycarbonyloxy, alkylthiocarbonyloxy, and aryloxycarbonyloxy, attached to one of said carbon atoms that is three atoms from an O attached to the phosphorus; together Z and W are connected via an additional 3-5 atoms to form a cyclic group, optionally containing one heteroatom, and V must be aryl, substituted aryl, heteroaryl, or substituted heteroaryl; together W and W′ are connected via an additional 2-5 atoms to form a cyclic group, optionally containing 0-2 heteroatoms, and V must be aryl, substituted aryl, heteroaryl, or substituted heteroaryl; Z is selected from the group consisting of —CHR2OH, —CHR2OC(O)R3, —CHR2OC(S)R3, —CHR2OC(S)OR3, —CHR2OC(O)SR3, —CHR2OCO2R3, —OR2, —SR2, —CHR2N3, —CH2aryl, —CH(aryl)OH, —CH(CH═CR22)OH, —CH(C≡CR2)OH, —R2, —NR22, —OCOR3, —OCO2R3, —SCOR3, —SCO2R3, —NHCOR2, —NHCO2R3, —CH2NHaryl, —(CH2)p—OR12, and —(CH2)p—SR12; p is an integer 2 or 3; with the provisos that: a) V, Z, W, W′ are not all —H; and b) when Z is —R2, then at least one of V, W, and W′ is not —H, alkyl, aralkyl, or alicyclic; R2 is selected from the group consisting of R3 and —H; R3 is selected from the group consisting of alkyl, aryl, alicyclic, and aralkyl; R12 is selected from the group consisting of —H, and lower acyl; M is selected from the group that attached to PO32−, P2O63−, or P3O94− is a biologically active agent, and is attached to the phosphorus in formula I via a carbon, oxygen, sulfur or nitrogen atom; and pharmaceutically acceptable prodrugs and salts thereof.

    摘要： The present invention is directed towards novel cyclic phosph(oramid)ate prodrugs of alcohol-, amine-, and thiol-containing drugs, their preparation, their synthetic intermediates, and their uses. Another aspect of the invention is the use of the prodrugs to treat diseases that benefit from enhanced drug distribution to the liver and like tissues and cells that express cytochrome P450, including hepatitis, cancer, liver fibrosis, malaria, other viral and parasitic infections, and metabolic diseases where the liver is responsible for the overproduction of the biochemical end product, e.g. glucose (diabetes); cholesterol, fatty acids and triglycerides (hyperlipidemia) (atherosclerosis) (obesity). In one aspect, the invention is directed towards the use of the prodrugs to enhance oral drug delivery. In another aspect, the prodrugs are used to prolong pharmacodynamic half-life of the drug. In addition, the prodrug methodology of the current invention is used to achieve sustained delivery of the parent drug. In another aspect, the prodrugs are used to increase the therapeutic index of the drug. In another aspect of the invention, a method of making these prodrugs is described. In another aspect, the prodrugs are also useful in the delivery of diagnostic imaging agents to the liver.
