Conventional and microwave assisted synthesis of small molecule based biologically active heterocyclic amidine derivatives

[摘要]：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 activities. At a dose of 50 mg/kg p.o. compounds 3a (36.6%), 3d (32%), 4d (31.0%) and 4e (33.8%) exhibited good anti-inflammatory activity, comparable to standard drug ibuprofen which showed 39% activity at 50 mg/kg p.o.
