“…Another report also pointed that ethanol could activate MAPK/NF-κB pathways during ALD conditions . Several recent studies also pointed out that galangin-mitigated tissue injury ascribe to an outstanding decline in NF-κB/MAPK pathway activation. − Our results displayed that galangin drastically inhibited the phosphorylation of p38, JNK, ERK, and NF-κB p65 in ethanol-addressed mouse colon tissues and Caco-2 cells. Accordingly, we speculate that galangin relieves the ethanol-induced inflammatory response, NLRP3 inflammasome activation, and intestinal barrier dysfunction by inhibiting the NF-κB/MAPK signaling pathway.…”

The potential of natural phytochemicals in addressing ethanol-related public safety concerns has been garnering attention. Galangin, a potent flavonoid renowned for its antioxidative and anti-inflammatory characteristics, is derived from the galanga plant, and propolis is derived from bees. Here, we documented the effects of galangin on ethanol-stimulated intestinal tight junction damage and investigated its potential protective mechanism in both in vivo and in vitro models, which has not been extensively investigated. Our results revealed that galangin efficaciously mitigated ethanol-induced intestine injury and dysfunction of the intestinal barrier. Concurrently, galangin significantly counteracted the ethanol-induced upregulation of NLRP3 inflammasomeassociated proteins and activated the mitogen-activated protein kinase (MAPK) and nuclear factor kappa-B (NF-κB) signaling pathways in both the mouse colon and Caco-2 cells. Interestingly, similar to galangin, inhibitors of MAPKs and the NF-κB p65 reduced ethanol-induced NLRP3 inflammasome activation and intestinal tight junction damage. To sum up, our results showed that galangin blocks the ethanol-induced perturbation of the intestinal barrier and activation of the NLRP3 inflammasome via the NF-κB/MAPK signaling pathways.

Enhancing collagen based nanoemulgel for effective topical delivery of Aceclofenac and Citronellol oil: Formulation, optimization, in-vitro evaluation, and in-vivo osteoarthritis study with a focus on HMGB-1/RAGE/NF-κB pathway, Klotho, and miR-499a

The majority of conventional osteoarthritis (OA) treatments are based on molecular adjustment of certain signaling pathways associated with osteoarthritis (OA) pathogenesis, however there is a significant need to search for more effective and safe treatments. This study centers around formulating Aceclofenac (ACF) with high bioavailability in combination with Citronellol oil and collagen. The optimal concentrations of Citronellol oil/D-Limonene oil, Tween 80, and Transcutol HP were determined using a pseudoternary phase diagram. The formulated nanoemulsions were studied for thermophysical stability. Thermodynamically stable formula were analyzed for droplet size, zeta potential, and in-vitro permeation. Then, collagen based nanoemulsion were prepared to capitalize on its efficacy in reducing osteoarthritis side effects and characterized for nano size properties. Formulae F10 and F10C were chosen as optimum nanosize formula. Hense, they were prepared and characterized as nanoemulgel dosage form. The nanoemulgel formulae F10NEG1 and F10CNEG1 showed reasonable viscosity and spreadability, with complete drug release after 4 h. These formulae were chosen for further In vivo anti-OA study. Collagen based ACF/citronellol emugel were able to modulate HMGB-1/RAGE/NF-κB pathway, mitigating the production of inflammatory cytokine TNF-α. They were also able to modulate Klotho and miR-499, reducing serum CTXII and COMP, by reducing the cartilage destruction. Histological investigations validated the efficacy, safety, and superiority of Aceclofenac in combination with Citronellol oil and collagen (F10CNEG1) over solo the treated group (F10NEG1 and blank). Hence, the findings of the current work encourage the use of this promising combined formula in treatment of OA patients. Graphical abstract
