Heterocyclic amidine derivatives have been synthesized by condensation of 2-cyanopyrazine, 4-cyanopyridine and 2-cyanopyridine with furfurylamine, histamine, 1-(3-aminopropyl)imidazole, 4-picolylamine, 2-picolylamine, and tryptamine respectively, in the presence of sodium methoxide as well as via microwave irradiation in good yields. All these compounds were screened for anti-inflammatory and anticancer
