Potent and Orally Bioavailable 8-Bicyclo[2.2.2]octylxanthines as Adenosine A1 Receptor Antagonists
摘要:
In the search for a selective adenosine A(1) receptor antagonist with greater aqueous solubility than the compounds currently in clinical trials as diuretics, a series of 1,4- substituted 8-cyclohexyl and 8-bicyclo-[2.2.2] octylxanthines were investigated. The binding affinities of a variety of cyclohexyl and bicyclo[2.2.2]octylxanthines for the rat and human adenosine A(1), A(2A), A(2B), and A(3) receptors are presented. Bicyclo[ 2.2.2] octylxanthine 16 exhibited good pharmaceutical properties and in vivo activity in a rat diuresis model (ED50=0.3 mg/ kg po). Optimization of the bridgehead substituent led to propionic acid 29 ( BG9928), which retained high potency ( hA(1), K-i=7 nM) and selectivity for the adenosine A1 receptor (915-fold versus adenosine A2A receptor; 12-fold versus adenosine A2B receptor) with improved oral efficacy in the rat diuresis model (ED50=0.01 mg/ kg) as well as high oral bioavailability in rat, dog, and cynomolgus monkey.

The invention is based on the discovery that compounds of Formula (I) are unexpectedly highly potent and selective inhibitors of the adenosine A1 receptor. Adenosine A1 antagonists can be useful in the prevention and/or treatment of numerous diseases, including cardiac and circulatory disorders, degenerative disorders of the central nervous system, respiratory disorders, and many diseases for which diuretic treatment is suitable. In one embodiment, the invention features a compound of formula (I).
