- EBM2 Middle Basai Endothelial 2
- D2O Heavy water
- the SB Bruker 400 MHz NMR spectrometer (Wissembourg, France) equipped with a QNP SB 1 H / 19 F- 13 C- 31 P probe operating in static mode was used to perform proton liquid NMR analyzes.
- the sequence used is a pulse sequence of the DOSY type
- the software used for the treatment of NMR spectra is Topspin 2.0 designed by the company Bruker.
- the sizes of the molecules in solution can be estimated by NMR of liquids using so-called diffusion experiments which make it possible to measure the diffusion coefficients of the species in solution.
- the experiment is carried out by applying a magnetic field gradient in a determined direction, in which direction the scattering of the particles is measured.
- Two treatments are possible following this type of experiment. Peak-to-peak analysis can be performed by very precisely parameterizing the intensity variation of the NMR peaks as a function of the field gradient (FIG. 1A).
- the only adjustment variable being the diffusion coefficient, it is then easy to obtain the size of the species in solution using the Stokes-Einstein equation already described.
- It is also possible to apply a Laplace transform which makes it possible to obtain, on a two-dimensional map (2D-NMR), diffusion / chemical displacement, the diffusion coefficient being directly measurable along the y-axis (FIG. 1B).
- DOSY experiments were conducted on water, ethanol, perfalgan and paracetamol solubilized in ethanol.

- the reference solutions (REF-Serum, REF, REF-30, REF-50, REF-80 and REF-EtOH) were thus subjected to DOSY experiments, in order to evaluate the effect of dilution by water. .
- the viscosity has a maximum for a molar fraction EtOH / Water close to 0.3 (60/40 v / v) at 25 ° C. and close to 0.2 (50/50 v / v) at 40 ° C. This is remarkable and indicates that the maximum viscosity is 2 to 3 times higher than that of pure water or pure ethanol.
- the EU-95 sample has an ethanol mole fraction of 0.236, that is to say in the zone where the viscosity has a maximum.
- hydro-alcoholic solutions are distinguished by particular macroscopic and molecular aspects, and the paracetamol molecules dissolved in such solutions have remarkable properties.
- the viscosity of the solution increases, reaching a maximum for a molar fraction EtOH / Water close to 0.3 (60/40 v / v) at 25 ° C. and close to 0.2 (50/50 v / v) at 40 ° C, which corresponds to a viscosity 2 to 3 times higher than that of pure water or pure ethanol.
- composition of water-ethanol mixtures in the range 50/50 leads to the smallest size for paracetamol, in particular at 40 ° C, the temperature closest to that of the human body. This can be interpreted by a weak wetting of the molecule that would make it more stealthy and give it a greater hydrophobic character, favoring its passage through membrane barriers, also hydrophobic.
- hCMEC / D3 cell line may constitute a relevant in vitro model of the blood-brain barrier, which mimics the constituents of the latter [Weksler et al., FASEB J. 2005 November; 19 (13): 1872'4. Epub 2005 Sep 1; Weksler et al., CNS Fluids Barriers. 2013 Mar 26; 10 (1): 16. doi: 10.1 186/2045 * 81 18 ⁇ 0 ⁇ ].
- the cells were first cultured in vials for cell culture (three passages of the culture after thawing frozen cells of the parent culture), then seeded in the "transpuit” system (more commonly referred to by its name in English language, "transwell”) described in Figure 4.
- the cells express the proteins characteristic of the formation of the blood-brain barrier, namely Z01, occludin, phalloidin and CD31.
- the degree of tightness of the barrier thus mimed is then determined using yellow lucifer.
- the yellow lucifer can not cross it.
- composition of the culture medium is indicated in Table 3 below:
- HPLC method has been developed, to allow the quantification of paracetamol crossing the previously described in vitro haematoencephalic barrier model, taking into account the culture medium and the sampling protocol.
- the equipment used consists of a P4000 pump, a 6000LP UV detector with a 50mm optical path, an AS 3000 autosampler equipped with a 100L loop and a SN 4000 system controller from Thermofisher (Courtaboeuf, France).
- the acquisition software used is Chromquest 5.0. The method developed is based on the following characteristics:
- abluminal paracetamol concentrations indicated in FIG. 6 correspond to the raw values obtained by HPLC quantification. Due to the dilution achieved for HPLC, they should be multiplied by a factor of 12 to match the actual values.
