  New imidazo[1,2-a]pyrazine derivatives with bronchodilatory and cyclic nucleotide phosphodiesterase inhibitory activities

  摘要：

  lNew imidazo[1,2-a]pyrazine derivatives have been synthesized either by direct cyclization from pyrazines or by electrophilic substitutions: The presence nf electron donating groups On position 8 greatly enhances the reactivity of the heterocycle towards such reactions on position 3 of the heterocycle. The activities of these derivatives in trachealis muscle relaxation and in inhihiting cyclic nucleotide phosphodiesterase(PDE) isoenzyme types III and IV have been assessed All compounds demonstrated higher relaxant potency than theophylline. All the derivatives were moderately potent in inhibiting the type IV isoenzyme of PDE but only those with a cyano group on position 2 were potent in inhibiting the type III isoenzyme.
