The cascade reaction of N-aryl-5-{[(dimethylamino)methylene]amino}-4-cyanoimidazoles with primary aromatic amines, under reflux in acetic acid, proved to be a general and efficient method for the regioselective synthesis of 6-arylaminopurines. A selection of these compounds was tested in breast cancer cell models MCF-7 and Hs578t and five compounds proved to be highly active and non-toxic to the non-neoplastic cell line MCF-10A. Furthermore, the compounds demonstrated apoptosis-inducing capacity in the cancer cells.
Synthesis and radical scavenging activity of phenol-imidazole conjugates
Correia, Carla,Leite, Cláudia,Proen?a, M. Fernanda,Carvalho, M. Alice
, p. 2768 - 2772 (2014/06/09)
Novel hydroxylated benzylideneamino imidazole derivatives were synthesized and their radical scavenging activity was assessed against DPPH and hydroxyl radicals. In the DPPH assay, most of the synthesized compounds showed an IC 50 in the range
New application of heterocyclic diazonium salts. Synthesis of pyrazolo[3,4-d][1,2,3]triazin-4-ones and imidazo[4,5-d][1,2,3]triazin-4-ones

The pyrazolo[3,4-d][1,2,3]triazin-4-ones 3 and imidazo[4,5-d][1,2,3] triazin-4-ones 4 are analogs structurally related to purines that have showed a wide and significant variety of biological activity. These compounds were synthesized by one-pot diazotization of 5-amino-1H-pyrazole-4-carbonitriles 1 and 5-amino-1H-imidazole-4-carbonitriles 2, respectively.
Synthesis of 5-amino-4-cyanoformimidoylimidazoles and 5-amino-4- cyanoimidazoles from amidines
Yahyazadeh, Asieh,Sharifi, Zahra
, p. 1339 - 1343 (2007/10/03)
Imidazole and formimidoylimidazole derivatives have been synthesized in high yields by a reaction between amidine and a strong or weak base depending on reaction conditions and mainly on the nature of the base used to induced cyclization. All compounds ha
A Facile Synthesis of 5-Amino-4-cyano-1-arylimidazoles and 5-Amino-1-aryl-4-(cyanoformimidoyl)-1H-imidazoles from N-Aryl-N'-formamidines
Alves, M. Jose,Booth, Brian L,Al-Duaij, Omar Kh.,Eastwood, Paul,Nezhat, Lida,et al.

Starting from readily available ethyl (Z)-N-(2-amino-1,2-dicyanovinyl)formimidate, N-aryl-N'-formamidines (2) can be prepared in good yields by reaction with aromatic amines at room temperature in the presence of an acid catalyst
