Many drugs have been withdrawn from the market because of their off-target effects, particularly hERG inhibition, which leads to severe cardiotoxicity. The NF-κB pathway plays a critical role in inflammation and immune response, making IKKβ an attractive therapeutic target. Thioridazine, a known inhibitor of IKKβ, has demonstrated potential anti-inflammatory effects. However, its clinical utility is severely limited by the strong inhibition of the hERG potassium channel, which increases the risk of cardiac arrhythmias. Therefore, it is necessary to develop safer IKKβ inhibitors using rational drug design approaches. By leveraging a similar compound library and in silico techniques, we aimed to retain the original therapeutic potential of thioridazine, while minimising its drawbacks. A library of thioridazine derivatives was computationally designed and screened by molecular docking and simulations. The selected compounds were subjected to patch-clamp analysis, confocal microscopy, western blotting, and qRT-PCR to evaluate their anti-inflammatory potential and hERG affinity, respectively. TDZ-D2{10-(2-oxo-2-pyrrolidin-1-ylethyl)acridin-9-one}, a thioridazine derivative, displayed significantly lower hERG binding while maintaining strong IKKβ inhibition, preserving IκBα stability, reducing NF-κB p65 translocation, and suppressing pro-inflammatory cytokine expression.

This narrative review explores the understanding of the gut-skin axis with the latest evidence on how gut dysbiosis occurs in psoriasis, characterized by reduced microbial diversity and its shifts, and how it contributes to pathogenesis and exacerbation of psoriasis. Notably, recent scientific literature evidence suggests that the alteration of gut microbiome in psoriasis includes a decreased level of beneficial species like Faecalibacterium prausnitzii and a rise in the level of proinflammatory bacterial species like Prevotella copri. Mechanistic insights reveal that gut-derived metabolites, impaired barrier functions, and immune signaling, particularly involving IL-23 and Th17 cells, play a pivotal role in this axis, linking intestinal health to cutaneous manifestations. Both animal and human trials underscore the therapeutic potential of interventions targeting the gut microbiota, including prebiotics, probiotics, dietary modifications, and FMT, demonstrating some promising but variable effects on disease severity and systemic inflammation. Despite these advances, translating the gut-skin axis into clinical practice presents a notable challenge due to limited scientific evidence, a lack of standardised microbiome profiling, and the absence of universally accepted biomarkers to monitor and stratify therapeutic outcomes.

This study is the first to evaluate the chemical composition, antioxidant and anti-inflammatory activities, dermal safety, and wound-healing potential of Veitchia arecina leaf fractions in a rat model. The study aimed to elucidate their mechanism of action in tissue regeneration. The chemical composition of light petroleum ether and n-butanol soluble fractions of Veitchia arecina was analyzed via gas-liquid chromatography-mass spectrometry (GLC-MS) and liquid chromatography-electrospray ionization tandem mass spectrometry (LC-ESI-MS/MS), respectively. In-vitro antioxidant (DPPH), anti-inflammatory (COX-1), and MTT assays were performed utilizing a 5% gel formulation, with povidone-iodine serving as the standard. The phytochemical analysis of the tested fractions using GLC-MS and LC-ESI-MS/MS revealed the presence of sterols, terpenes, vitamin E isomers, and fatty acids in light petroleum ether soluble fraction as well as flavonoid glycosides and phenolics in n-butanol soluble fraction. Both fractions showed significant antioxidant and COX-1 inhibitory activities comparable to Trolox and ibuprofen. The topical gel formulations exhibited no dermal toxicity while improving healing by attenuating inflammation and oxidative stress, enhancing blood vessel formation, re-epithelization, formation of collagen, and restoring skin architecture. Notably, the n-butanol fraction demonstrated superior efficacy in facilitating granulation tissue maturation.

Pro- and anti-inflammatory cytokines were measured, and acute toxicity studies were performed to determine LD50. Thirty-three compounds were identified in EAFHJ, including phenolic acids, flavonoids, and coumarins. In the FST, EAFHJ reduced the immobility time to 131.50 ± 3.46 s at 100 mg/kg compared to 139.88 ± 4.58 s in the control group (p < 0.01). In the EPM, the group treated with 200 mg/kg of EAFJH spent 48.14% of the time in the open arms, compared to 31.30% of the control group (p < 0.05). In the PTZ trial, the latency to myoclonic seizures was 3.0 ± 0.5 min at 200 mg/kg of EAFHJ compared with 1.01 ± 0.5 min in the control group (p < 0.05). The LD50 of the EAFJH was greater than 5000 mg/kg, indicating low toxicity. Furthermore, a significant reduction in pro-inflammatory cytokine levels (IL-6, TNF-α, IL-1β) and an increase in anti-inflammatory cytokines (IL-10, IL-4) were observed.

Multiple sclerosis is one of the most common causes of disability in young adults affecting approximately 3 million individuals worldwide. Among them, females are considered at higher risk than males. It disrupts the normal functioning of life badly and major symptoms include loss of sensation, poor vision, impaired hearing, and cognitive abnormalities. Several treatments and drugs have been used to treat this medical condition, but they pose serious side effects also. So, the need of the hour is to explore such natural bioactive compounds that have neuroprotective properties, thus leading to the treatment of neurodegenerative disorders. Among various plants with medicinal properties, Gerbera jamesonii is a plant that exhibits antioxidant, anti-inflammatory, and neuroprotective properties. To enhance its therapeutic potential, this study aimed to load its ethanolic extract into solid-lipid nanoparticle formulations (SLNs), which is an innovative approach for treatment because nanoparticles provide effective targeted drug delivery due to their extremely small size. Solid-lipid nanoparticles were prepared using the emulsification-solvent evaporation method. For experimental design, 30 Wistar rats were randomly divided into seven groups (n = 10): normal, demyelination disease model, standard drugs, dimethyl fumarate and fingolimod (FTY 720) 15 mg/kg, and three treatment groups: GJ-NPs 250 mg/kg, 500 mg/kg, and 750 mg/kg.

Biochemical analyses such as determination of inflammatory biomarkers and antioxidant enzymes were performed. The plant extract was subjected to HPLC to examine its phenolic compounds which are active in healing neurodegeneration. Physiological changes in rats were observed such as motor dysfunction and anxiety-like behavior caused by cuprizone. Behavioral tests showed significant improvement of motor function, muscular coordination, and enhanced cognitive abilities in the treatment groups as compared to the demyelination disease model. Histopathology of the rat brain regions showed significant differences in the normal and demyelinated areas.
