The synthesis and biological activity of lipophilic derivatives of bicine conjugated withN3-(4-methoxyfumaroyl)-L-2,3-diaminopropanoic acid (FMDP)—an inhibitor of glucosamine-6-phosphate synthase
摘要:
A series of bis-N,N-(2-hydroxyethyl)glycine (bicine) derivatives, conjugated with an inhibitor of glucosamine-6-phosphate synthase, have been synthesized and their lipophilic and antifungal properties have been tested. The obtained compounds demonstrated higher lipophilicity than free inhibitor (FMDP) and, in consequence, an increased potential to cross the cytoplasmic membrane. All the tested compounds show better antifungal activity than parent compound.

Provided are carboxylic ester derivatives of formula (I), methods of preparing them, and methods for using them. These compounds are prodrugs of D-isoglutamyl-[D/L]-tryptophan. The in vitro bioconversion of some of the prodrugs to the parent drug D-isoglutamyl-D-tryptophan (or thymodepressin) was tested in human hepatocytes and in human blood. In vivo pharmacokinetic studies following oral administration of some of the prodrugs to rats are also reported.
Provided are a nitroxoline prodrug and a use thereof. Specifically, provided are a compound represented by formula (I) or a pharmaceutically acceptable salt thereof, a preparation method therefor, a composition containing the compound, and a use thereof in the preparation of anti-infective and antitumor drugs, and definitions of groups in formula (I) are as stated in the specification. The compound represented by formula (I) has better pharmacokinetic parameters such as solubility, blood medicine concentration, or half-life period than nitroxoline. The compound represented by formula (I) can reduce the frequency of drug administration, and has potential for application in other fields other than the field of urinary tracts.
