Article	Year
Chemical studies of the radical scavenging mechanism of bisorbicillinol using the 1,1-diphenyl-2-picrylhydrazyl radical. Chemical communications (Cambridge, England), 2002, Mar-21, Issue:6 A potent antioxidant, bisorbicillinol, which is a member of the bisorbicillinoid family isolated from the culture broth of Trichoderma sp. USF-2690, produces a stable radical-terminated symmetric dimer by donating two hydrogen atoms to the 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical.

Sorbicillinol, a key intermediate of bisorbicillinoid biosynthesis in Trichoderma sp. USF-2690. Bioscience, biotechnology, and biochemistry, 2001, Volume: 65, Issue:10 In the course of our screening program for free radical scavengers from Trichoderma sp. USF-2690, we found an unidentified metabolite (1) that appeared by the method used for HPLC analysis. Metabolite 1 gradually decreased with the production of bisorbicillinoids and was easily missed during the general isolation procedure. The LC-ESI-MS (negative) analysis for 1 gave m/z 247 as the (M-1)- ion peak. The hydrolysis of synthetic 6-O-acetylsorbicillinol (+/- -2) by 0.05 M KOH and acetylation of product 1 in an aqueous solution indicated that the structure of 1 was (6S)-4-(2,4-hexadienoyl)-3,6-dihydroxy-2,6-dimethyl-2,4-cyclohexadien-1-one, designated sorbicillinol, a quinol that has been postulated to be important in bisorbicillinoid biosynthesis. Topics: Bepridil; Biphenyl Compounds; Chromatography, High Pressure Liquid; Cyclohexanones; Fermentation; Free Radical Scavengers; Gas Chromatography-Mass Spectrometry; Kinetics; Picrates; Trichoderma	2001
