  Substituted 1,3-Dipropylxanthines as Irreversible Antagonists of A1 Adenosine Receptors

  摘要：

  This report describes the synthesis of 29 xanthines containing a chemoreactive chloroaryl beta-chloroethylamino, alpha,beta-unsaturated carbonyl bromoacetyl, 3-(fluorosulfonyl)benzoyl, or 4-(fluorosulfonyl)benzoyl group as part of an exocyclic 1-, 3-, or 8-substituent. The xanthines inhibited the binding of [H-3]-8-cyclopentyl-1,3-dipropylxanthine ([H-3]CPX) to the A(1) adenosine receptor (A(1)AR) of DDT1 MF2 cells at IC(50)s in the low-nanomolar to low-micromolar range. Seven of the 29 analogues irreversibly inhibited the binding of [H-3]CPX without changing the K-D of that ligand; five were 1,3-dipropylxantines having the following reactive groups as 8-substituents: (bromoacetamido)methyl (24), (bromoacetamido)ethyl (25), (bromoacetamido)propyl (26), [4-(fluorosulfonyl)benzamido]methyl (33) or 3-[[4-(fluorosulfonyl)benzoyl]oxy]cyclopentyl (42). Both 8-cyclopentyl-3-[3-[[4-(fluorosulfonyl)benzoyl]oxy]propyl]-1-propylxanthine (53) and 8-cyclopentyl-3-bis[3-[[4-(fluorosulfonyl)benzoyl]oxy]propyl]xanthine (55) inhibited [H-3]CPX binding irreversibly. Five of the ligands, including 26, 33 (IC50 = 49 mu M), and 53 (IC50 = 9 mu M), antagonized the binding of [H-3]NECA to the A(2a)AR of PC12 cells, but unlike binding to the A(1)AR, binding to the A(2a)AR was completely reversible. The potency of 33 (IC50 = 2 mu M, 72% loss of CPX binding at 1 mu M) and 53 (IC50 - 0.01 mu M, 74% loss of CPX binding at 0.05 mu M) and their seletivity for the A(1)AR suggest that those two ligands may be useful in studies of the structure and function of that receptor.
