“…The research has shown that some compounds from this group have promising antibacterial, antifungal and antitumor activities (Ainscough et al, 1998;Avaji et al, 2009;Azaz et al, 2007;Mahalingam et al, 2008;Wang et al, 2007), and some of their derivatives are suggested as reagents for the treatment of genetic and neurodegenerative disorders, such as thalassemic syndrome and Alzheimer's (Armstrong et al, 2003;Bernhardt et al, 2007;Buss et al, 2005;Donnelly et al, 2008). Besides, some of these compounds are used as highly sensitive analytical reagents, luminescent probes and molecular sensors (ávila Terra et al, 2002;Bakir et al, 2008;Basu et al, 2007;Pinto et al, 2004;Sreeja et al, 2003).…”
