Synthetic bifunctional molecules containing drug moiety and pharmacokinetic modulating moiety
First Claim
1. A synthetic bifunctional molecule of less than about 5000 daltons consisting of a drug moiety and a pharmacokinetic modulating moiety, wherein said drug moiety and said pharmacokinetic modulating moiety are different and have been chosen so that said pharmacokinetic modulating moiety modulates at least one pharmacokinetic property of said drug moiety upon administration of said synthetic bifunctional molecule to a host as compared to a free drug control comprising said drug moiety, wherein said pharmacokinetic property is selected from the group consisting of half-life, hepatic first-pass metabolism, volume of distribution and degree of blood protein binding, and wherein the pharmacokinetic modulating moiety is selected from the group consisting of a ligand for α
- -1 acid glycoprotein, sulfisoxazole and naproxen.
