dynorphin amide (1-13), Ala(2)-(5-F-Phe)(4)- Usage And Synthesis
Description
Dafphedyn, [D-Ala2, (F5) Phe4]-dynorphin 1-13-NH2 (DAFPHEDYN) is a potent analog of dynorphin 1-13. Intracerebroventricular administration of the dynorphin analog, [D-Ala2,(F5)Phe4]-dynorphin 1-13-NH2 (DAFPHEDYN) in rats produced diuresis and profound analgesia. Both effects were antagonized by central administration of naltrexone or naloxone. Intravenous administration of 10, 25, and 50 mg/kg of DAFPHEDYN failed to induce diuresis. The increased potency of DAFPHEDYN was apparent from the failure of an equal dose of the parent compound (dynorphin 1-13) to produce diuresis and the failure of [D-Ala2]-dynorphin 1-13-NH2 to produce analgesia. Radioligand binding studies indicated the DAFPHEDYN retains the same degree of kappa selectivity as the parent compound (dynorphin 1-13) though a drop in affinity occurred. DAFPHEDYN may be of significant interest because it retains the essential pharmacology of the parent compound and exhibits marked in vivo potency.
