Abstract

A series of alkyl-and halo-substituted 84 l-piperazinyl) imidazo [1, 2-alpyrazinea were prepared using two approaches, the condensation of a-halocarbonyl derivatives with an aminopyrazine or the oxidation-dehydration of a [(@-hydroxyalky1) aminol pyrazine. These imidazo [1, 2-a] pyrazines were evaluated for their binding affinity to the (~ 1, a2,@ I, and 4 2 adrenergic receptors as well as their ability to lower blood glucose in insulin resistant ...
