4-Amino-5-aryl-6-arylethynylpyrimidines: Structure–activity relationships of non-nucleoside adenosine kinase inhibitors
摘要:
A series of non-nucleoside adenosine kinase (AK) inhibitors is reported. These inhibitors originated from the modification of 5-(3-bromophenyl)-7-(6-morpholin-4-ylpyridin-3-yl)pyrido[2,3-d]pyrimidin-4-ylamine (ABT-702). The identification of a linker that would approximate the spatial arrangement found between the pyrimidine ring and the aryl group at C(7) in ABT702 was a key element in this modification. A search of potential linkers led to the discovery of an acetylene moiety as a suitable scaffold. It was hypothesized that the aryl acetylenes, ABT-702, and adenosine bound to the active site of AK (closed form) in a similar manner with respect to the orientation of the heterocyclic base. Although potent acetylene analogs were discovered based on this assumption, an X-ray crystal structure of 5-(4-dimethylaminophenyl)-6-(6-morpholin-4-yipyridin-3-ylethynyl)pyrimidin-4-ylamine (16a) revealed a binding orientation contrary to adenosine. In addition, this compound bound tightly to a unique open conformation of AK. The structure-activity relationships and unique ligand orientation and protein conformation are discussed.

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.
