Design and synthesis of novel prostaglandin E2 ethanolamide and glycerol ester probes for the putative prostamide receptor(s).


ABSTRACT: Novel prostaglandin-ethanolamide (PGE2-EA) and glycerol ester (2-PGE2-G) analogs were designed and synthesized to aid in the characterization of a putative prostamide receptor. Our design incorporates the electrophilic isothiocyanato and the photoactivatable azido groups at the terminal tail position of the prototype. Stereoselective Wittig and Horner-Wadsworth-Emmons reactions install the head and the tail moieties of the PGE2 skeleton. The synthesis is completed using Mitsunobu azidation and peptide coupling as the key steps. A chemoenzymatic synthesis for the 2-PGE2-G is described for first time.
