  1-(4-Amino-phenyl)-3-methyl-5,7-dipropyl-1H,7H-1,2,3a,5,7,8-hexaaza-cyclopenta[a]indene-4,6-dione 、 二苯基乙酰氯 在 三乙胺 作用下， 以 1,4-二氧六环 为溶剂， 反应 6.0h， 以80%的产率得到1,3-di-n-propyl-2,4-dioxo-6-methyl-8-[4-((diphenylacetyl)amino)phenyl]-1,2,3,4-tetrahydro-[1,2,4]-triazolo-[3,4-f]-purine

  Synthesis, biological and modeling studies of 1,3-di-n-propyl-2,4-dioxo-6-methyl-8-(substituted) 1,2,3,4-tetrahydro [1,2,4]-triazolo [3,4-f]-purines as adenosine receptor antagonists

  摘要：

  A new series of potential adenosine receptor antagonists with a [1,2,4]-triazolo-[3,4-f]-purine structure bearing at the 1 and 3 position n-propyl groups have been synthesized, and their affinities at the four human adenosine receptor subtypes (A(1), A(2A), A(2B) and A(3)) have been evaluated. In this case the presence of n-propyl groups seems to induce potency at the A(2A) and A(3) adenosine receptor subtypes as opposed to our previously reported series bearing methyl substituents at the 1 and 3 positions. In particular the non-acylated derivative 17 showed affinity at these two receptor subtypes in the micromolar range. Indeed, preliminary molecular modeling investigations according to the experimental binding data indicate a modest steric and electrostatic antagonist-receptor complementarity.
