Several 3-formylquinolone derivatives (8a-c) were synthesized to assay the antibacterial activity both in vitro and in vivo. In vitro, all of the compounds 8a-c showed lower activity than that of the corresponding 3-carboxyl compounds 1a-c, and in vivo, they showed higher activity than that of compounds 1a-c. After oral administration of 3-formyl compounds 8a-c to mice, the compounds were rapidly metabolized into 3-carboxyl compounds 1a-c. In particular, the 3-formyl derivative (8a) of norfloxacin (NFLX, 1a) gave a 2-fold higher serum level than that of NFLX and functioned as a prodrug of NFLX.

Disclosed are conjugates including a recognition element covalently bonded to or linked through a linker to a payload. The payload is a pharmaceutical agent (e.g., an antineoplastic agent, anti-infective agent, or anti-inflammatory agent) or a diagnostic agent. Also disclosed are methods of using the conjugates.
