STIGMATELLIN Usage And Synthesis
UsesStigmatellin is a cytochrome bc1 complex inhibitor.
DefinitionChEBI: A member of the class of chromones that is isolated from Stigmatella aurantiaca Sg a15.
Purification MethodsStigmatellin A is stable in aqueous solution at neutral pH but decomposes at pH <5. It is purified by recrystallisation from toluene/hexane. It has UV max: nm () 248sh (4,100), 258 (59,500), 267 (65,500)max: 3550m, 1645chs, 1635ss, 1620ss, 1590s, 1510m and 905m cm-1. It gives colour reactions at 110o with vanillin/H2SO4 (grey), Ce(IV)/(NH4)2SO4 (yellow) and phosphomolybdate (blue-grey). [H.fle et al. Justus Liebigs Ann Chem 1882 1984.] It inhibits electron transport [Jagow & Link Methods Enzymol 126 253 1986, Robertson et al. Biochemistry 32 1310 1933], and has antibiotic properties [Kunze et al. J Antibiot 37 454 1984]. The 7t,9t,11c-isomer is Stigmatellin B.
