A drug conjugate, composition, and method for delivering active antimicrobials based on existing antibiotics through a hexose phosphate transporter (UhpT) by conjugating the antimicrobials with non-metabolizable hexose phosphates. Methods of co-administering antibiotics with non-metabolizable hexose phosphates as antimicrobials are also disclosed. Non-metabolizable hexose phosphates can constitutively and strongly induce expression of UhpT which significantly improves the efficacy and/or antimicrobial spectrum of antibiotics. This drug conjugate, composition and method will permit reuse of many FDA approved antibiotics that have been abandoned or fallen into disuse due to their current low efficacy and/or resistance to these antibiotics by pathogens.
Disclosed are a drug having renal selectivity and a drug carrier for specifically transporting a drug supported thereon to a kidney. A segment structure specifically recognizable in the kidney is utilized. More specifically, since a segment structure represented by formula (I) is kidney-oriented, introduction of a drug into a molecule having the segment structure can provide a renal targeting drug. A compound, which has the segment structure and can support a drug thereon, can be utilized as a drug carrier which can specifically transport a drug supported thereon to the kidney.
A-U-V- (I)
wherein A represents glycosyl, such as glucosyl, mannosyl, or 2-deoxy-glucosyl; U represents O, S, or NH; and V represents an aromatic hydrocarbon or a straight-chain or branched C1-18 aliphatic hydrocarbon.
