resorufin

01/01/1991 - "4. The microsomes contained about 43 pmol P-450/mg protein corresponding to 0.51 nmol P-450/g midgut and 64 pmol P-450/g body weight, respectively, and converted benzyloxyresorufin into resorufin with a Vmax of 2.12 pmol resorufin/min.mg protein and a Km of 770 nM benzyloxyresorufin at 25 degrees C, pH 8.0. "
03/01/2004 - "Increased liver-to-body weight ratios coincided with a significant induction of uridinediphosphate-glucuronosyltransferase (UDGPT; two to four-fold), and ethoxy- and pentoxy-resorufin-O-deethylase (EROD and PROD) at the two highest doses in all exposures. "
03/01/1993 - "The induction of hepatic P450 2B protein and ethoxy-, pentoxy-, and (benzyloxy)resorufin O-dealkylation activities, and epoxide hydration activity and liver/body weight ratio increase were examined in male F344/NCr rats fed the various congeners for 14 days at doses equimolar to 500 ppm phenobarbital. "
01/15/1990 - "In the guinea pig, 5 days after treatment with TCDD at 10 micrograms/kg, TCDD toxicity was also evident (loss of body weight and thymus weight); there was no change in DT-diaphorase as measured by resorufin reduction, confirming by a different assay the observation of Beatty and Neal (Biochem Pharmacol 27: 505-510, 1978) that TCDD does not induce DT-diaphorase in guinea pig liver, and 7-EROD was increased 8-fold. "
01/01/2017 - "The present study investigated whether treatment with MA (300 mg Sb5+/kg body weight/day, subcutaneously) for 24 days affected the activities of cytochrome P450 (CYP)1A (ethoxyresorufin- O-deethylase), CYP2A5 (coumarin 7-hydroxylase), CYP2E1 ( p-nitrophenol-hydroxylase), CYP2B9/10 (benzyloxy-resorufin- O-debenzylase), or CYP3A11 (erythromycin- N-demethylase) in the livers of Swiss Webster (SW) and DBA-2 male and female mice. "

08/15/2009 - "In this study we found that activities of ethoxy- and benzyloxy-resorufin-O-dealkylases, p-nitrophenol-hydroxylase and erythromycin-N-demethylase (mediated by CYP1A, 2B, 2E1 and 3A, respectively) were depressed, while uridine-glucuronosyl-transferase (a phase 2 enzyme) was unaltered in liver microsomes of Plasmodium berghei-infected (parasitemia >20%) male Swiss Webster mice. "

07/01/1999 - "The effects of starvation on liver microsomal chlorzoxazone 6-hydroxylase and ethoxy-resorufin-O-deethylase activities are discussed in the context of the impact of physiological states on the ability of fish to detoxify marine xenobiotics."
07/01/1999 - "When these activities were expressed per gm/liver (to account for the starvation-induced changes in liver microsomal protein), chlorzoxazone 6-hydroxylase activity doubled over control during starvation but ethoxy-resorufin-O-deethylase was not significantly changed. "
07/01/1999 - "Ethoxy-resorufin-O-deethylase activity (pmol/min/mg microsomal protein) was reduced with starvation, chlorzoxazone 6-hydroxylase activity (pmol/min per mg microsomal protein) initially decreased but then increased over controls. "
07/01/1999 - "Starvation has been previously demonstrated to induce CYP2E1 activity (assayed as chlorzozazone-6-hydroxylase activity) in mammals and this study was undertaken to determine the effects of starvation on liver chlorzozaxone-6-hydroxylase and ethoxy-resorufin-O-deethylase activity (a CYP1A1 activity) in juvenile winter flounder liver microsomes. "

07/09/2018 - "Herein, we adapt the labeling approach with a tetracystein tag (TC) and a biarsenical resorufin-based label (ReAsH) for monitoring the HIV-1 particles during the early stages of HIV-1 infection by CLEM. "
01/01/2020 - "DF-1 cells transfected with GFP1-10 prior to PBG98-VP1-GFP11 infection or stained with a biarsenical derivative of the red fluorophore resorufin (ReAsH) following PBG98-VP1-TC infection, had green or red foci in the cytoplasm, respectively, that colocalized with VP3 and dsRNA, consistent with VFs. "
08/17/2021 - "One resazurin derivative, resorufin pentyl ether, significantly reduces vaginal colonization by Neisseria gonorrhoeae in a mouse model of infection. "
07/07/2021 - "A dual-caged resorufin probe for rapid screening of infections resistant to lactam antibiotics."
01/01/2011 - "Regardless of mouse sex, infection depressed the activities of CYP1A [ethoxy/methoxy-resorufin-O-dealkylases (EROD/MROD)], 2B9/10 [pentoxy/benzyloxy-resorufin-O-dealkylases (PROD, BROD)], 2E1 [p-nitrophenol-hydroxylase (PNPH)] and 3A11 [erythromycin N-demethylase (END)] on PID 55 but not on PID 30. "

01/01/2023 - "Furthermore, we conducted fluorescence imaging in vivo in 4T1 tumor-bearing mice, and the ADHP probe can rapidly oxidize to form resorufin in response to ROS, which can effectively reduce the background fluorescence signal compared with the single resorufin probe. "
01/01/2010 - "Using specific resorufin derivatives as substrates in vitro, the concentration of meso-zeaxanthin needed for 50 % inhibition of CYP1A2 (7-methoxyresorufin-O-demethylase) was 5 µg/ml, for CYP2B 1/2 (7- pentoxyresorufin-O-depentylase) was 8 µg/ml and for CYP1A1 (7-ethoxyresorufin-O-deethylase) was 12 µg/ml, while that of CYP 2E1 (aniline hydroxylase) was 7µg/ml and for CYP 1A, 2A, 2B, 2D and 3A (aminopyrene-N-demethylase) was 10.5 µg/ml. Evaluated using nitroso diethyl amine (NDEA) induced hepatocellular carcinoma in rats, treatment with meso-zeaxanthin reduced the tumor incidence when compared to the control group. "
01/01/2017 - "This work includes the successful separation and SERS detection of a fluorescent dye compounds (resorufin and sulforhodamine 640), fluorescent anti-tumor drugs (Adriamycin and Daunomycin), and purine and pyrimidine bases (adenine, cytosine, guanine, hypoxanthine, and thymine)."
