ABSTRACT:
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.
