TARGETED DRUG DELIVERY USING SULFONAMIDE DERIVATIVES
-
, (2008/06/13)
The present invention relates to Glutathione S-transferase (GST)/Reduced Glutathione (GSH) as a means for the in-vivo release of a drug that has been conjugated to specific electrophilic moieties via a sulfonamide bond. The drug may be an anticancer agent (or one with other therapeutic properties) carrying a free —NH— which has been derivatized by the attachment of an electrophile containing a moiety, such as p-CN— or p-NO 2-pyridinylsulfonyl groups, or p-NO 2- or 2,4 dinitrophenylsulfonyl groups, or suitable derivatives thereof, to make a prodrug. Optionally, the sulfonamide moiety may have attached to it a targeting molecule. The present invention also provides Glutathione S-transferase (GST)/Reduced Gluthathione (GSH) as a means for the release of a protected amino derivative that has been conjugated to specific electrophilic moieties via a sulfonamide bond. The precursor is a synthetic intermediate carrying a free —NH— which has been derivatized by the attachment of an electrophile via a sulfonamide bond.

The novel compounds, 4'-deoxy-daunomycin and 4'-deoxy-adriamycin, as well as derivatives thereof are useful as anti-tumor antibiotics. These compounds are prepared by condensing the corresponding aglycone with a novel trifluoracetyl protected reactive halo sugar which is 2,3,4,6-tetradeoxy-3-trifluoroacetamido-L-threo-hexopyranosyl chloride.
