Current Opinion in Infectious Diseases, 2003
Production of melanin has been associated with virulence in diverse microorganisms. Melanization of fungi has been noted for many years in predominantly subcutaneous infections such as chromoblastomycosis and more recently most extensively studied in a yeast causing systemic infection, Cryptococcus neoformans. Pigmented fungi are increasingly important

Nature, 1947
IT has been suggested recently1 that 5 : 6: 5â:6â-tetrahydroxy-indigo (I), or a quinone or semi-quinone derived from it, is an important constituent of melanin, the black pigment produced by the oxidation of tyrosine and 3 : 4-dihydroxyphenylalanine2.

Melanin is an irregular light-absorbing polymer containing indoles and other intermediate products derived from the oxidation of tyrosine. Melanin is widely dispersed in the animal and plant kingdoms. It is the major pigment present in the surface structures of vertebrates.

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1983
An overview of the melanins and lipofuscin is presented, taking an integrating account of their morphological relationships and chemical characteristics wherever possible. This has required inclusion of the ommochromes, the schlerotizing process, and consideration of related neurotransmitters. A number of questions are raised and commented upon.

To the Editor.— Good theories should give way to better theories, and even good theories may become untenable as new information is discovered. Periodic questioning of dogma is a useful way to reevaluate dogma, lest we be complacent with obsolete conclusions. The article by Warwick L.

Binding of Memantine to Melanin: Influence of Type of Melanin and Characteristics
Pharmaceutical Research, 2003The objectives of this study were to characterize sepia, synthetic, and bovine melanin and to determine their binding characteristics to the drug memantine.Physical methods were used to characterize sepia, synthetic, and bovine melanin. Their binding properties toward memantine were determined in deionized water and phosphate-buffered saline (PBS) at ...
