The synthesis, antimicrobial activity and absorption characteristics of some novel heterocyclic disazo dyes

Antimicrobial natural fibres

“…The length of alkyl groups is also important in these dyes (Liu and Sun, 2009). A new disazo dye has been shown to have antifungal activity (Karci et al ., 2009). Several benzophenon chromophoric groups were covalently bound to cotton cellulose.…”

Extraction of natural dyes from Curcuma longa, Trigonella foenum graecum and Nerium oleander, plants and their application in antimicrobial fabric

“…The discovery of synthetic dyes in the West in the nineteenth century dealt a massive blow to Indian textile industry (Ali and El-Mohamedy, 2011). Some of the chemical dyes in use have been found hazardous to human life causing skin and lung diseases (Ayoola et al, 2008;Edeoga et al, 2005;Karc et al, 2009). Therefore, intense research in the recent past has focused on the search for dyes from plants, animals, insects and minerals (Zibbu and Batra, 2010;Giri Dev et al, 2009;Ibrahim et al, 1997;Junior and Zanil, 2000;Kumar et al, 2009).…”

The structural characterization and DNA binding of pyridyl-azo-acetylacetonato complexes of zinc(II), cadmium(II) and mercury(II)

“…Over the past few years, an intensive effort has been focused to develop metal-based drugs with improved clinical effectiveness, reduced toxicity and broader spectrum of activity than that of cisplatin [7,8]. Heterocyclic compounds have valuable properties such as chemotherapeutic agents [3], dyestuffs [9,10], co-polymer [11] etc. Metallo-heterocycles (metal complexes of heterocycles) develop exciting chemistry and have been used in catalysis, redox reactions, photoactivity, organic synthesis, drugs etc.…”
