WebIn our previous paper we reported synthesis and biological activity of two cyclic analogs of endomorphin-2 (EM-2): Tyr-c (Lys-Phe-Phe-Asp)-NH (2) and Tyr-c (Asp-Phe-Phe-Lys)-NH (2), achieved by making an amid bond between Lys and Asp side-chains. The first analog did not bind to the mu-opioid receptor, the affinity of the second one was very low. township update download
