الوصف (Description)

Tocofersolan is a polyethylene glycol derivative of α-tocopherol and is a water-soluble vitamin E analog[1]. Tocofersolan has antioxidant activity and serves as an orally bioavailable source of vitamin E[2]. Tocofersolan increases the solubility and bioavailability of some drugs, and improves their pharmacokinetic properties[3]. Tocofersolan is usually used in drug delivery systems or nutraceuticals[4][5].

In vitro, Tocofersolan (3.3µM to 16.5mM; 60min) inhibited P-glycoprotein (P-gp) - mediated drug efflux in Caco-2 cells with an IC50 of 5.86µM[6].

In vivo, Tocofersolan (1µM) co-exposure for 5 days post-fertilization in larval zebrafish reversed the locomotor hypoactivity caused by benzo[a]pyrene (5µM) exposure[7].

البروتوكول (Protocol)

Cell experiment [1]:

Cell lines

 Caco-2 cells

Preparation Method

 Caco-2 cells were grown to 90% confluence in 75cm2 T-flasks with DMEM supplemented with 10% FBS and 1% NEAA. Culture media were changed every second day, and cells were grown at a temperature of 37°C in an atmosphere of 85% relative humidity and 5% CO2. Trypsinized Caco-2 cells were spin labeled by incubating a suspension (2.0×107 cells/mL) in Krebs Ringer Buffer (KRB; pH 7.4) for 30min at 37°C with 0.5mM of a spin label stock solution (10mM 5-doxyl stearic acid (5-SA) in ethanol). Different concentrations of Tocofersolan (3.3µM to 16.5mM) were added via stock solutions, and cell suspensions were incubated for 60min. After suspension centrifugation (4min at 1200g), supernatant was removed and the cell pellet was washed and resuspended in KRB to give a final concentration of 1.0×108 cells/mL. To quench residual free spin label, chrome oxalate (final concentration 2.0mM) was added and the ensuing cell suspension (100µL) was filled into the test tube and placed in a 4103 TM/ 8609 cavity. ESR measurements were performed at room temperature using a Bruker ESP300 E spectrometer with an ER081 (90/30 C5) magnet. Cell membrane fluidity was depicted via the cell membrane order parameter S. S can be derived from the ESR spectral line splitting.

Reaction Conditions

 3.3µM to 16.5mM; 60min

Applications

 Tocofersolan had negligible effects on Caco-2 cell membrane fluidity at concentrations up to 0.33mM, but significant fluidization effects were observed at higher concentrations (above 1.65mM).

إرشادات عامة
اختر مذيبًا مناسبًا وفقًا لبيانات ذوبانية المنتج. بعد التحضير، قسّم المحلول المخزون إلى أجزاء لتجنب دورات التجميد والذوبان المتكررة.
استخدم المحاليل المخزونة خلال 6 أشهر عند حفظها في -80°C، أو خلال شهر واحد عند حفظها في -20°C.
لتحسين الذوبانية، سخّن الأنبوب إلى 37°C وعرّضه للموجات فوق الصوتية لمدة مناسبة.
شروط الشحن
تُشحن عينات التقييم مع عبوات تبريد. وتُشحن الأحجام الأخرى المتاحة في درجة حرارة الغرفة، أو مع عبوات تبريد عند الطلب.
