• Human keratinocytes of cell line NCTC R13 are pre-cultured at 37 ° C in a 5% CO 2 atmosphere with the culture medium DMEM (Life Technologies 21969035) for 24 h.
• the cells are treated with a compound of formula I for 24 hours.
• the inflammatory-inducing agent phorbol myristate acetate (PMA, 0.1 g / ml) is added. After 24 hours of incubation, the culture is collected and analyzed.
• the release is used by means of an ELISA kit DE0100 (R & D Systems) to investigate the release of the inflammation marker prostaglandin E2 (PGE2).
• the negative control takes place without the presence of the active ingredient PMA and without a compound of the formula I.
• the positive control is carried out in the presence of PMA and indomethacin (1 ⁇ molar).
• Example 4b Effect on the activity of leukocyte elastase
• Example 4c effect on the activity of hyaluronidase 5,7-Dihydroxychroman-4-one or 5,7-dihydroxy-2,2-dimethylchroman-4-one in phosphate buffer (0.1 M) is treated with hyaluronidase (HYAL, Sigma type IV-S , H3884; 1 mg / L preincubated in phosphate buffer (0.1 M)). Then hyaluronic acid (AH, Sigma H-1876, 1.2 mg / ml) is added and the mixture is incubated for 1 h at 37 ° C. Subsequently, the remaining hyaluronic acid (HA) is precipitated with serum albumin (BSA, Sigma A7888) and determined photometrically.

• the simplest and most cost-effective method is to calculate the wound area by measuring with a tape measure or ruler. However, in this two-dimensional method, it is assumed that the wound surface corresponds to a [regular] geometric shape, e.g. Rectangle (length x width), circle (diameter x diameter) or oval (maximum diameter x perpendicular to maximum diameter). Another method of calculating wound size is based on the ellipse design formula (length x width x .785).
• Wound tracing In wound tracing, another two-dimensional procedure, the wound contour is transferred with a pen directly to a transparent foil applied to the wound. The tracing can be done with little technical effort at the bedside perform and does not provide any special training requirements to the doctor. The comparison of standard-made tracings clarifies the course of wound healing. The procedure represents only a small burden for the patient. The tracings can be filed in the medical record and / or entered into a data processing system with a simple scanner. The most important limitation of this measurement method is the inaccurate detection of the wound circumference in the case of unclear wound margins, which impairs the reliability and accuracy of the procedure.
• Kundin Device This is a commercially available three-dimensional measuring device for calculating wound size and wound volume.
• Discharge Method By filling the wound cavity with the aid of saline or alginate filling material, a three-dimensional impression of the wound can be produced.
• Planimetry This is a method of measuring wound volume using a two-dimensional [planar] representation (photograph or image)
• Computer-assisted stereophotogrammetry In computer-aided stereophotogrammetry originally developed for earth mapping, a three-dimensional image is constructed from two measurement images of the same area. In a calculation process, the two images are searched for corresponding pixels and the height of the respective point is calculated from the distance between these corresponding points.
• Yenidunya and Demirseren for example, superimposed the digital image of a wound on the computer screen with the wound outline drawn on a transparent foil. This image, which can be generated without major stress on the patient and can be digitally stored, was used for surgical planning and the evaluation of wound healing.
• Non-invasive assessment methods such as e.g. the measurement of transepidermal water loss (TEWL) allows a continuous assessment of the processes in the skin in case of impairment of the barrier function of the epidermis.
• TEWL transepidermal water loss
• laser Doppler scanning

• adipocytes Normal human adipocytes are isolated from biopsies (plastic surgery). Immediately after receipt, the samples are incubated for 30 min at 37 ° C in the presence of collagenase (supplied by Sigma). The suspension of adipocytes is then rinsed and threefold diluted in the culture medium.
• the culture medium is formed, for example, from:
• adipocytes in suspension are incubated for 4 h at 37 0 C in the presence of different concentrations of a compound of formula I.
• Radiolabeled acetate (2-C 14 , 60.87 ⁇ Ci / ml, Amersham) is then added to the preparation.
• the lipids are prepared according to the method described by Bligh and Dyer, Can. J. Biochem. Physiol., 37, 922 (1959), evaporating under nitrogen and the incorporated radioactivity is quantified by liquid scintillation (reference liquid scintillator LKB 1210, supplied by Rackbeta).
• the possible interaction between the radiolabeled acetate and a compound of formula I is evaluated to determine the specificity of the To confirm labeling by incubating the highest concentration of the compound of formula I with acetate alone.
