RESUMO
Benzodiazepines are allosteric modulators of the GABA(A) receptor. The traditionally prescribed benzodiazepines are nonselective and suffer from numerous side effects. Upon the identification of receptor subtypes, we set out to discover selective agents with the anticipation that these agents would have superior therapeutic potential. Herein, we describe the synthesis and biological evaluation of substituted 7,8,9,10-tetrahydroimidazo[1,2-c]pyrido[3,4-e]pyrimidin-5(6H)-ones and disclose that these compounds exhibit functional selectivity at the benzodiazepine receptor of GABA(A) receptor subtypes. The alpha(2)/alpha(3)-selective partial agonist 42 exhibited potent in vivo activity.
