“…To counter drug resistance, several researchers are continuously striving to develop diverse classes of heterocyclic molecules, including quinolines, 1 thieno [2,3- d ]pyrimidine, 2 dipeptide-sulfonamides, 3 spirooxindoles, 4 pyrimidine, 5 and molecular hybrids. 6–8 The heterocyclic motif pyrazine exhibits diverse pharmacological properties and has been explored to develop antimycobacterial, antibacterial, antifungal, antidiabetic, diuretic, anticancer, antiviral, hypnotic, and analgesic agents. Some of the pyrazine derivatives are now clinically recognized drugs all over the world.…”
