Orally Active Adenosine A1 Receptor Agonists with Antinociceptive Effects in Mice
摘要:
Adenosine A(1) receptor (A(1)AR) agonists have antinociceptive effects in multiple preclinical models of acute and chronic pain. Although numerous AIAR agonists have been developed, clinical applications of these agents have been hampered by their cardiovascular side effects. Herein we report a series of novel A(1)AR agonists, some of which are structurally related to adenosine 5'-monophosphate (5'-AMP), a naturally occurring nucleotide that itself activates A(1)AR These novel compounds potently activate A,AR in several orthogonal in vitro assays and are subtype selective for A(1)AR over A(2A)AR, A(2B)AR, and A(3)AR. Among them, UNC32A (3a) is orally active and has dose-dependent antinociceptive effects in wild-type mice. The antinociceptive effects of 3a were completely abolished in A(1)AR knockout mice, revealing a strict dependence on A(1)AR for activity. The apparent lack of cardiovascular side effects when administered orally and high affinity (K-i of 36 nM for the human A(1)AR) make this compound potentially suitable as a therapeutic.

Amino acids present in domains of an umami taste receptor are described herein, wherein the amino acids interact with at least one nucleotide derivative and/or at least one transmembrane compound that potentiates, modulates, increases, and/or enhances the activity of the umami receptor. Such compounds can be used in flavor compositions to enhance the umami taste and/or palatability of food products.
