The synthesis of novel 5-aminoimidazoles derivatives with anticancer activity

[Excerpt] The imidazole nucleus is present in a significant number of biomolecules and the inclusion of this moiety in organic scaffolds is considered an important synthetic strategy in drug discovery.[1] 5-Aminoimidazoles are interesting building blocks in medicinal chemistry since they are key components in many bioactive molecules and their derivatives showed a wide pharmacological potential as anticancer drugs.[1] The hydrazones constitute an important class of biological active drug molecules due to their wide range of pharmacological properties that include antitumoral activities.[2] Amidrazone derivatives could be considered very promising in the perspective of new drug discovery, because they are very effective as building blocks to obtain various heterocycles.[2,3] The α-hydrazononitriles are a special case of compounds belonging to the family of hydrazones that is less common in the literature, but has a great interest due to their pharmacological applications.[4] (...)FCT (NMR portuguese network); FCT and FEDER-COMPETE-QREN-EU [Pest-C/QUI/UI0686/2011 (FCOMP-01-0124-FEDER-022716)
