N6-Ethyl-2-alkynyl NECAs, selective human A3 adenosine receptor agonists
摘要:
A series of N-6-ethyl-2-alkynyl NECA (5'-N-ethylcarboxamidoadenosine) analogs were synthesized and their binding affinity with the four human adenosine receptors was evaluated. One of the compounds ZR1121 shows high affinity with hA(3) receptor and its selectivity over hA(1) receptor is 1-2 log orders greater than IB-MECA or Cl-1B-MECA, the currently employed selective A(3) agonists.

search for agonists for the elusive A2B adenosinereceptor subtypes, 2‐phenylhydroxypropynyl‐5′‐N‐methylcarboxamido adenosine (PHPMECA, 14), 2‐phenylhydroxypropynyl‐5′‐N‐propylcarboxamido adenosine (PHPPECA, 15), and N 6‐ethyl‐2‐phenylhydroxypropynyl‐5′‐N‐ethylcarboxamidoadenosine (19) were synthesized on the basis that introduction of alkynyl chains in 2‐position of adenosinederivatives resulted in
