  (Acyloxy)alkyl carbamate prodrugs of norfloxacin

  摘要：

  As a new prodrug approach to norfloxacin (NFLX) we prepared the acetoxyalkyl carbamates of the type NFLXCO-OCHR-OAc by the reaction of sodium or mercuric acetate on NFLX alpha-chloroalkyl carbamates. These prodrugs did not have the bitter taste of NFLX. In vitro, the acetoxyethyl carbamate exhibited activity only against Staphylococcus spp. and was inactive against Gram-negative organisms. However, in the presence of serum and intestinal homogenate, esterase-catalyzed hydrolysis of the ester bond in these modified carbamates led to a cascade reaction resulting in the rapid regeneration of NFLX. At high oral doses of the prodrug, the acetaldehyde produced as a side product in the breakdown of the promoiety caused a slight decrease in alcohol metabolism in a mouse model. The bioavailability of NFLX from the acetoxyethyl carbamate was lower compared to an equivalent dose of NFLX when given as an oral suspension in rhesus monkeys, presumably because of the lower aqueous solubility of the prodrug.

  This invention relates to novel (acyloxyalkoxy) carbonyl derivatives as a bioreversible prodrug moieties for primary and secondary amine functions in drugs having a primary or secondary amine function thereon. Hydrolytic enzymes are used to trigger the regeneration of the parent amine drug of the carbamate prodrug moiety. The case also contains pharmaceutical composition, method of treatment and process claims.
