The invention relates to therapeutic agents referred to as `pseudopeptides` being formed from at least one peptide radical connected by a peptide bond to a therapeutically active molecule or derivative of a therapeutically active molecule. The therapeutic agents of the invention may be in the form of derivatives such as salts, esters and amides. The basis of action of the agents of the invention is the ability of the agents of the invention to cross bodily biological barriers because of the basically peptide structure of the agents. The invention also includes the preparation of the agents of the invention.
Orally nonabsorbed or poorly absorbed drugs may be converted to orally absorbed prodrug derivatives by derivatization of free functional groups selected from amino, hydroxyl, mercapto, phosphate and/or carboxyl with groups sensitive to mild basic conditions such as 9-fluorenylmethoxycarbonyl (Fmoc), 2-sulfo-9-fluorenylmethoxycarbonyl (Fms), and fluorenylmethyl (Fm).

The present invention relates to novel metabolically stable and centrally active TRH analogues and prodrug forms of these analogues, wherein a functional portion of TRH is substituted with a pyridinium moiety or an ester moiety. Methods of synthesis and use of the TRH analogues and associated prodrugs are also provided.
本发明涉及新的代谢稳定和具有中枢活性的 TRH 类似物以及这些类似物的原药形式,其中 TRH 的功能部分被吡啶基或酯基取代。还提供了合成和使用 TRH 类似物及相关原药的方法。
