Abstract: The present disclosure relates to a series of tricyclic compounds, their tautomers, polymorphs, stereoisomers, prodrugs, solvates, pharmaceutically acceptable salts, pharmaceutical compositions containing them and methods of treating conditions and diseases that are mediated by adenosine receptor (AR) activity. The disclosure also relates to process of preparation of these tricyclic compounds of Formula I. These compounds are useful in the treatment, prevention or suppression of diseases and disorders that may be susceptible to improvement by antagonism of the adenosine receptor. The disclosure also relates to the process of preparation of the tricyclic compounds, and to pharmaceutical compositions containing them.
