Coloranti

Applications Labelled Curcumin (C838500). A natural phenolic compound. Potent anti-tumor agent having anti-inflammatory and anti-oxidant properties. Induces apoptosis in cancer cells and inhibits phorbol ester-induced protein kinase C (PKC) activity. Reported to inhibit production of inflammatory cytokines by peripheral blood monocytes and alveolar macrophages. Potent inhibitor of EGFR tyrosine kinase and IκB kinase. Inhibits inducible nitric oxide synthase (iNOS), cycloxygenase and lipoxygenase. Easily penetrates into the cytoplasm of cells, accumulating in membranous structures such as plasma membrane, endoplasmic reticulum and nuclear envelope.

Applications As a dye for wool and silks; as colorant in food, drugs, and cosmetics. In biochemistry as an adsorption-elution indicator for chloride estimations. Tartrazine (otherwise known as E number E102, C.I. 19140, or FD&C Yellow 5) is a synthetic lemon yellow azo dye used as a food coloring. Tartrazine appears to cause the most allergic and intolerance reactions of all the azo dyes, particularly among asthmatics and those with an aspirin intolerance. Dyes and metabolites, Environmental Testing.A recent report has shown that Tartrazine may be useful in 3D bio-printing of organ-like architectures.
