Glutathionyl-3-hydroxykynurenine glucoside
Glutathionyl-3-hydroxykynurenine glucoside (GSH-3-OHKG) is a fluorophore and UV filter compound isolated from human lenses. The UV filter compounds present in lenses are thought to protect the lens and retina from UV-induced photodamage and/or to reduce chromatic aberration. Unlike the other UV filter compounds, 3-hydroxykynurenine glucoside (3-OHKG) and 4-(2-amino-3-hydroxyphenyl)-4-oxobutanoic acid O-glucoside (AHBG), which remain relatively stable or decrease slightly in concentration during adult life, GSH-3-OHKG was found to increase in relative concentration with age (PMID: 10409626).
