Anti Inflammatory

Atopic dermatitis is an inflammatory disease associated with defective skin barrier. The co-administration of a lipid-enhancing skin barrier composed of ceramide with an anti-inflammatory agent is required to effectively treat atopic dermatitis. As atopic dermatitis treatment is affected by the dosage and frequency of medication, the development of nanoparticles that have long-term efficacy with a single dose would be advantageous. In this study, skin-sensitive chitosan nanoparticles codelivering ceramide and C-phycocyanin were developed to provide anti-inflammatory effects with no cytotoxicity, and their effect on stratum corneum formation in a rat atopic dermatitis model was examined. Analysis of the messenger RNA expression of keratinization factors demonstrated that the stratum corneum–formation effect of poly(lactic-co-glycolic acid) nanoparticles containing ceramide was similar to or higher than that of ceramide alone. Compared to the nanoparticles without C-phycocyanin, nanoparticles coated with C-phycocyanin and chitosan attenuated histamine release. In addition, despite frequent washing, the nanoparticles were well fixed to the epidermis after their administration. The results suggest that a single treatment with the combination of lipid therapy/anti-inflammatory nanoparticles is a convenient and high-efficiency means to increase stratum corneum formation in atopic dermatitis patients.

Inflammatory Effect

Non-steroidal anti-inflammatory drugs (NSAIDs) are widely used in the world, primarily due to their high efficiency for the treatment of inflammatory induced pain syndrome. The main feature of NSAIDs is a combination of anti-inflammatory, analgesic, antipyretic, and anticoagulant properties. However, their long-term use is associated with side effects in the gastrointestinal tract including peptic ulcers and other. We developed and synthesized molecule of methyl (4-О-β-glucopyranosyloxy)-benzoic acid. The anti-inflammatory effect of methyl (4-О-β-glucopyranosyloxy)-benzoic acid evaluated using the carrageenan-induced hindpaw edema model. The study shows that the intragastrically administration of test substance to animals reduces inflammatory process.

The influence of a topically applied formulation containing components of natural moisturizing factor (NMF) on barrier-related parameters of the stratum corneum (SC) was investigated in vivo using confocal Raman microspectroscopy in a randomized, placebo-controlled double-blind study on 12 volunteers for 14 days. This method allowed for the elucidation of subtle differences between the verum and the placebo even though the components of the verum naturally occur in the SC. This differentiation is not possible non-invasively by conventional methods. In this study, we found that the applied verum and placebo formulations disrupted the equilibrium of water, NMF and lipids in the SC. The adverse effects of the formulation could be mitigated by incorporating it into a simplified supplementation of NMF molecules. As a long-term effect, the amount of strongly bound water increases at 30–40% SC depth (p < 0.05) and the amount of weakly bound water decreases at 30–40% SC depth (p < 0.05) for the verum. This supplement was also unexpectedly able to prevent intercellular lipids (ICL) disorganization in selected depths. In the long term, the verum treatment limited the lateral disorganization of the ICL to the upper 20% SC depth. Further research is required to elucidate the interplay of these factors in the SC, to better understand their contribution to the equilibrium and barrier function of the skin. This understanding of the interaction of these naturally occurring components could help in the future to develop and optimize topical treatments for diseases like psoriasis, atopic dermatitis, ichthyosis where the skin barrier is disrupted.
