Imidazo[1,2-a]pyrimidines as Functionally Selective and Orally Bioavailable GABAAα2/α3 Binding Site Agonists for the Treatment of Anxiety Disorders
摘要:
A series of high-affinity GABA(A) agonists with good oral bioavailability in rat and dog and functional selectivity for or the GABA(A)alpha 2 and -alpha 3 subtypes is reported. The 7-trifluoroinethylimidazopyrimidine 14g and the 7-propan-2-olimidazopyrimidine 14k are anxiolytic in both conditioned and unconditioned animal models of anxiety with minimal sedation observed at full BZ binding site occupancy.

Pd-II-catalyzed aromatic C-H bond activation using cyano as a directing group was carried out in TFA medium. Biphenyl-2-carbonitrile derivatives were therefore synthesized from aryl nitriles and aryl halides in moderate to good yields.
