/In a rat metabolism study/... Preliminary study: Group A, 2 male (M)/2 female (F) exposed to a single oral dose of [14C]fluridone (...radiopurity 99.8%; for test solutions [14C]fluridone was mixed w/[12C]fluridone, ...100% purity; test substance was suspended in 1% sodium carboxymethyl cellulose [CMC]) at ~10 mg/kg. Group B, 1M/1F exposed to a single oral dose at ~1000 mg/kg. Urine, feces and cage rinses were collected daily for 7 days (because expired (trapped) 14CO2 accounted for <1% of the dose after 24 hr, further 14CO2 measurements were discontinued). Definitive study: Group C, vehicle controls, 2M/2F exposed to a single oral dose of 1% CMC. Group D, 5M/5F exposed to a single oral dose at ~7.4 mg/kg. Group E, 7M/7F exposed to ~10 mg/kg unlabeled fluridone once daily for 14 days, then 5M/5F exposed on day 15 to ~10 mg/kg [14C]fluridone. Group F, 5M/5F exposed to a single oral dose at ~900 mg/kg. ...Clinical signs (lack of mobility, abnormal and rapid head movement, squinting, loss of balance and cage biting) occurred only at the HD (Groups B and F), clearing within 24 hr. Results, Group A: by 7 days, 12.52%/12.89% (M/F) was excreted in urine and 72.76%/81.79% in feces. Group B: by 7 days 4.83%/3.43% was excreted in urine and 86.43%/86.31% in feces. Group D: by 24 hr 11.14%/10.44% was excreted in urine and 72.46%/77.72% in feces. By 7 days 11.61%/10.93% was excreted in urine and 79.19%/84.62% in feces. Combined excretion (including cage rinse) by 7 days was 92.93%/98.74%. Group E: by 24 hr 9.54%/8.51% was excreted in urine and 70.69%/69.90% in feces. By 7 days 10.11%/9.14% was excreted in urine and 79.80%/81.79% in feces. Combined excretion (including cage rinse) by 7 days was 92.81%/94.21%. Group F: by 24 hr 2.40%/2.43% was excreted in urine and 27.16%/27.18% in feces (thus, a relative delay in fecal excretion at the HD). By 7 days 8.30%/8.07% was excreted in urine and 91.58%/90.09% in feces. Combined excretion (including cage rinse) by 7 days was 101.02%/99.62%. Total tissue residues were always <1% of the dose (Groups D-F). Under all conditions, highest tissue levels occurred in the liver. The major metabolites were a variety of polar and non-polar compounds resulting from aromatic hydroxylations and heteroaromatic N-demethylation. The parent compound was the primary fecal component over the 1st 72 hr.
In a metabolism study in rats, fluridone was rapidly and almost completely absorbed into the systemic circulation and eliminated in both the male and female rats within 3 days. The total radioactivity recovered within 3 days after dosing in the urine and feces were 78-90% and 87- 97% of administered dose in males and females, respectively. The majority (approximately 70%) of the radioactivity was eliminated via feces. No tissue accumulation was observed.

The bioconversion of 5-deoxystrigol to sorgomol by the sorghum, Sorghum bicolor (L.) Moench
摘要:
Strigolactones, important rhizosphere signalling molecules and a class of phytohormones that control shoot architecture, are apocarotenoids of plant origin. They have a structural core consisting of a tricyclic lactone connected to a butyrolactone group via an enol ether bridge. Deuterium-labelled 5-deoxystrigol stereoisomers were administered to aquacultures of a high sorgomol-producing sorghum cultivar, Sorghum bicolor (L) Moench, and conversion of these substrates to sorgomol stereoisomers was investigated. Liquid chromatography-mass spectrometry analyses established that 5-deoxystrigol (5-DS) and ent-2'-epi-5-deoxystrigol were absorbed by sorghum roots, converted to sorgomol and ent-2'-epi-sorgomol, respectively, and exuded out of the roots. The conversion was inhibited by uniconazole-P, implying the involvement of cytochrome P450 in the hydroxylation. These results provide experimental evidence for the postulated biogenetic scheme for formation of strigolactones, in which hydroxylation at C-9 of 5-DS can generate sorgomol. (C) 2013 Elsevier Ltd.
