The present disclosure relates to novel triazolo-pyrimidine compounds targeting adenosine receptors (especially A1 and A2, particularly A2a). Chalcones are the biogenetic precursors of flavonoids and isoflavonoids, which are abundant in plants. Medicinal Significance of Pyrimidines Pyrimidine derivatives demonstrated a variety of biological and pharmacological activities including antifolates, antiprotozoal, anti-AIDS and antitumor activity. The presence of a pyrimidine base in thymine, cytosine and uracil, which are the essential building blocks of nucleic acids, DNA and RNA is one of the possible reasons for their activities 3. In medicinal chemistry pyrimidine derivatives have been very well known for their therapeutic applications. A novel pyrimidine compound having an excellent antagonistic activity against adenosine receptors (A1, A2A, and A2B receptors). Six of the derivatives are piperazinylpyrimidines.
