  Synthesis and pharmacology of pyrido[2,3-d]pyrimidinediones bearing polar substituents as adenosine receptor antagonists

  摘要：

  Amino-substituted pyrido[2,3-d]pyrimidinediones have previously been found to bind to adenosine A(1) and A(2A) receptors in micromolar concentrations. The present study was aimed at studying the structure-activity relationships of this class of compounds in more detail. Most of the investigated compounds were provided with polar substituents. such as ethoxycarbonyl groups and basic amino functions, in order to improve their water-solubility. The compounds were synthesized starting from 6-amino-1,3-dimethyfuracil via different reaction sequences involving (cyano)acetylation, Vilsmeier formylation, or reaction with diethyl ethoxymethylemalonate (EMME). The most potent and selective compound of the present series was 6-carbethoxy-1,2,3,4-tetrahydro-1.3-dimethyl-5-(2-naphthylmethyl) aminopyrido[2,3-d]pyrimidine-2,4-dione (11c) with a K-i value of 5 nM at rat and 25 nM at human A, receptors. The compound was more than 60-fold selective versus A(3) and more than 300-fold selective versus A2A receptors. It showed all over 300-fold improvement with respect to the lead compound. In GTP gamma S binding studies at membranes of Chinese hamster ovary cells recombinantly expressing the human adenosine A, receptor, 11c behaved as an antagonist with inverse agonistic activity. A regioisomer of 11c, 6-carbethoxy-1,2,3,4-tetrahydro-1,3-dimethyl-7-(2-naphthylmethyl)aminopyrido[2,3-d]pyrimidine-2,4-dione (7a) in which the 2-naphthylmethylamino substituent at position 5 of 11c was moved to the 7-position, was a relatively potent (K-i = 226 nM) and selective (> 20-fold) A(3) ligand. In the series of compounds lacking an electron-withdrawing ethoxycarbonyl or cyano substituent in the 6-position, compounds with high affinity for adenosine A(2A) receptors were identified. Such as 1,2,3,4-tetrahydro-1,3-dimethyl-5-(1-naphthyl)aminopyrido[2,3-d]pyrimidine-2,4-dioile 16b (K-i human A(2A) = 81.3 nM, K-i human A(1) = 153 nM, and K-i human A(3) > 10,000 nM).

  ethoxymethylenemalonate (1) and 6-amino-1,3-dimethyluracil (2) was determined to be regioselective. Under acidic conditions the product was the previously isolated 7-oxopyrido[2,3-d]pyrimidine (3), while in the presence of one equivalent of base followed by thermal cyclization, the isomeric 5-oxopyrido[2,3-d]pyrimidine (5) is formed.

  The reaction of the 5-thioformyluracil 1 with phenylhydrazine and various amines readily afforded the hydrazone 3a and Schiff bases 3b-d, respectively. Further, carbanions and Wittig reagents reacted with 1 to give pyrido[2, 3-d]pyrimidines 4 and 9. The corresponding 5-formyluracil 2 possessed much lower reactivities toward these nucleophiles than did 1.
