  Synthesis and Structure−Activity Relationships of 3,7-Dimethyl-1-propargylxanthine Derivatives, A_2A-Selective Adenosine Receptor Antagonists

  摘要：

  A series of 8-substituted derivatives of 3,7-dimethyl-1-propargylxanthine (DMPX) was synthesized and investigated as A(2A) adenosine receptor antagonists. Different synthetic strategies for the preparation of DMPX derivatives and analogues were explored. A recently developed synthetic procedure starting from 3-propargyl-5,6-diaminouracil proved to be the method of choice for the preparation of this type of xanthine derivatives. The novel compounds were investigated in radioligand binding studies at the high-affinity adenosine receptor subtypes A(1) and A(2A) and compared with standard A(2A) adenosine receptor antagonists. Structure-activity relationships were analyzed in detail. 8-Styryl-substituted DMPX derivatives were identified that exhibit high affinity and selectivity for A(2A) adenosine receptors, including 8-(m-chlorostyryl)-DMPX (CS-DMPX, K-i A(2A) = 13 nM, 100-fold selective), 8-(m-bromostyryl)-DMPX (BS-DMPX, K-i A(2A) = 8 nM, 146-fold selective), and 8-(3,4-dimethoxystyryl)-DMPX (K-i A(2A) = 15 nM, 167-fold selective). These and other novel compounds are superior to the standard A(2A) adenosine receptor antagonists KF17837 (4) and CSC (5) with respect to A(2A) affinity and/or selectivity.
