Biological Activity
Tyloxapol (100 μg/mL) triggers the detachment of HEK293 cells[2].
Tyloxapol induces nuclear fragmentation and the appearance of apoptotic nuclei[2].
Tyloxapol increases the risk of pulmonary haemorrhage, causes cytotoxicity in epithelial and red blood cells, and induces lysis of human Jurkat T-lymphoblasts[2].

Animal Model:Twenty-one adult male Wistar rats, aged 11–12 weeks weighing 180-200 g[1].
-
Dosage:50 mg/kg.
-
Administration:Injected intraperitoneally, BW, every other day.
-
Result:Caused a significant (P < 0.05) elevation in the levels of TBARS combined with an inhibition of the antioxidant enzymes (GPx, GST, CAT, SOD) in rat plasma, liver, and brain.
Induced DNA fragmentation and inhibited the activities of acetylcholinesterase and mono aminoxidase in the brain.
Please do not refer to only one article to determine the experimental conditions. It is recommended to determine the optimal experimental conditions (animal strain, age, dosage, frequency and cycle, detection time and indicators, etc.) through preliminary experiments before the formal experiment.
Tyloxapol (Triton WR1339, 50 mg/kg) causes significant decreases in the activities of the AChE and MAO enzymes in rat plasma and brain[1].
Tyloxapol leads to significant reduction in the plasma urea, creatinine, and bilirubin[1].
Administration: 400 mg/kg• i.p.• a single dose for 24 h[1].
Rats: Wistar-Imamichi• male• weighing 230-270 g[2].
Administration: 400 mg/kg• i.v. through a tail vein• a single dose for 24 h[2].
Rats: Wistar• male• 11-12 weeks of age• weighing 180-200 g[3].
Administration: 50 mg/kg• i.p.• every other day for 28 days[3].
(2) Tyloxapol was dissolved in phosphate buffer solution (PBS, pH 7.4). Twenty-four hours after administration, blood, liver, kidney, and forebrain tissues samples were collected for the comet assay. Bone marrow samples of from femurs were collected to perform the micronucleus assay[1].
(3) At the end of the 28th day of the experimental period, all animals of each group were anesthetized with ether and sacrificed. Blood samples were collected from anesthetized rats in test tubes containing heparin as an anticoagulant and placed immediately on ice[3].

L02 cells were transfected with GSTA1 or control plasmids for 36 h and further treated with or without bicyclol for 12 h. Intracellular TG levels were analyzed after induction by OA containing Tyloxapol (200 µM), a lipoprotein lipase inhibitor that can inhibit the breakdown of triglycerides by binding to lipase. Overexpression of GSTA1 or treatment with bicyclol significantly decreased the rate of TG synthesis compared to the control.
