The present invention provides, in part, compounds of Formula I: and pharmaceutically acceptable salts thereof and N-oxides thereof; processes and intermediates for preparation of; and compositions and uses thereof. The present invention further provides D1 agonists with reduced D1R desensitization, D1 agonists with a reduced β- arrestin recruitment activity relative to Dopamine, D1 agonists interacting significantly with the Ser188 but not significantly with the Ser202 of a D1R when binding to the D1R, D1 agonists interacting less strongly with the Asp103 and interacting less strongly with the Ser198 of a D1R when binding to the D1R, and their uses.

A series of imidazo[1,2-a]pyrazine derivatives was synthesized by condensation of α-halogenocarbonyl compounds and aminopyrazines. Various compounds resulted from competitive reactions or reagent isomerization and demonstrated in vitro uterine-relaxing and in vivo antibronchospastic activities. On isolated atria, 5-bromoimidazo[1,2-a]pyrazine showed positive chronotropic and inotropic properties; the latter was associated with an increase in the cyclic AMP tissue concentration. Potentiation of the isoproterenol positive inotropic effect of 5-bromoimidazo[1,2-a]pyrazine and the lack of blockade of the 5-bromoimidazo[1,2-a]pyrazine positive inotropic effect by propranolol suggested phosphodiesterase-inhibiting properties.
