Design, Synthesis, and Structure−Activity Relationship of 6-Alkynylpyrimidines as Potent Adenosine Kinase Inhibitors
摘要:
Adenosine (ADO) is an extracellular signaling molecule within the central and peripheral nervous system. Its concentration is increased at sites of tissue injury and inflammation. One of the mechanisms by which antinociceptive and antiinflammatory effects of ADO can be enhanced consists of inhibition of adenosine kinase (AK), the primary metabolic enzyme for ADO. Novel nonnucleoside AK inhibitors based on 4-amino-6-alkynylpyrimidines were prepared, and the importance of the length of the linker at the 5-position for high affinity AK inhibition was demonstrated. Compounds with 2- and 3-atom linkers were the most potent AK inhibitors. Optimization of their physicochemical properties led to 31a and 37a that effectively reduced pain and inflammation in animal models.

alkynylpyrimidine classes of nonnucleoside adenosine kinase inhibitors 2 and 3. 4-Amino-substituted pteridines 8a-e were generally less active than corresponding 5- and 6-substituted pyridopyrimidines 2. Pyrazolopyrimidine 13c with IC(50)=7.5 nM was superior to its open chain alkynylpyrimidine analog 13g (IC(50)=22 nM) while pyrrolopyrimidines such as 17a were inactive.
