Anti-Psoriasis Effect of Diclofenac and Celecoxib Using the Tail Model for Psoriasis. Pharmaceutics 2022; 14:pharmaceutics14040885. [PMID: 35456720 PMCID: PMC9025614 DOI: 10.3390/pharmaceutics14040885] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/13/2022] [Revised: 04/09/2022] [Accepted: 04/14/2022] [Indexed: 01/27/2023] Open
Abstract
Non-steroidal anti-inflammatory drugs (NSAIDs) showed effects in some hyperproliferative dermatologic pathologies. The aim of the study is the assessment of anti-psoriasis effect of diclofenac and celecoxib using a mice tail model. The topical application of substances on the proximal mice tails was performed for two weeks. The effects on the epidermal granular layer and mean epidermal thickness (excluding the stratum corneum) were evaluated using hematoxylin–eosin staining. Orthokeratosis degree and percentual drug activity were calculated. A positive control group treated with tretinoin and two negative controls (white soft paraffin and untreated mice) were used. Orthokeratosis degree significantly increased in all the NSAIDs groups (celecoxib 1%, 2% and diclofenac 1%, 2%) and in the tretinoin 0.05% group, versus negative controls. Celecoxib 1% and 2%, tretinoin 0.05% and white soft paraffin significantly increased mean epidermal thickness, versus untreated mice. The values obtained in the case of celecoxib 2% ointment regarding the orthokeratosis degree and percentual drug activity are providing premises for further investigations regarding this effect and the mechanisms of action involved. Celecoxib 2% had the greatest percentual drug activity and is a promising substance for the anti-psoriasis topical treatment. Along with the COX-2 inhibition, celecoxib might have an anti-psoriasis effect by other independent mechanisms.

Abstract
Inflammation is a biological function which triggered after the mechanical tissue disruption or from the responses by the incidence of physical, chemical or biological negotiator in body. These responses are essential act provided by the immune system during infection and tissue injury to maintain normal tissue homeostasis. Inflammation is a quite complicated process at molecular level with the involvement of several proinflammatory expressions. Several health problems are associated with prolonged inflammation, which effects nearly all major to minor diseases. The molecular and epidemiological studies jagged that the inflammation is closely associated with several disorders with their specific targets. It would be great achievement for human health around the world to overcome on inflammation. Mostly used anti-inflammatory drugs are at high risk of side effects and also expensive. Hence, the plant-based formulations gained a wide acceptance by the public and medical experts to treat it. Due to extensive dispersal, chemical diversity and systematically established biological potentials of natural products have induced renewed awareness as a gifted source for medications. However, today's urgent need to search for cheaper, more potent and safe anti-inflammatory medications to overcome on current situation. The goal of this review to compile an update on inflammation, associated diseases, molecular targets, inflammatory mediators and role of natural products. The entire text concise the involvement of various cytokines in pathogenesis of various human disorders. This assignment discussed about 321 natural products with their promising anti-inflammatory potential discovered during January 2009 to December 2018 with 262 citations.

Abstract
Exposure to air pollution is associated with increased respiratory morbidities and susceptibility to lung dysfunction. Ozone (O3) is commonly recognized as one of the most noxious air pollutant and has been associated with several lung pathologies. It has been demonstrated that decreased lung disorder severity and incidence are connected with the consumption of a diet rich in fruits and vegetables, suggesting that higher intake of dietary micronutrients and phytoactive compounds can be beneficial. However, dietary supplementation - i.e. vitamin E (α-tocopherol) or vitamin A - has not always been effective in improving pulmonary function. Recently, research on the role of nutritional antioxidants on human health has focused more on studying their uptake at the cellular level rather than their effective ability to scavenge reactvive oxygen species (ROS). The Scavenger Receptor B1 (SRB1) has been shown to play a prominent role in the uptake, delivery and regulation of vitamin E in the lung. Given the importance of SRB1 in maintaining lung tissue in a healthy condition, we hypothesize that its expression could be modulated by pollution exposure, which thus could indirectly affect the uptake and/or delivery of lipophilic substances, such as vitamin E. To characterize the molecular mechanism involved in the redox modulation of SRB1, its cellular levels were assessed in human alveolar epithelial cells after O3 exposure. The results demonstrated that O3 induced the loss of SRB1 protein levels. This decline seems to be driven by hydrogen peroxide (H2O2) as a consequence of an increased activation of cellular NADPH oxidase (NOX), as demonstrated by the use of NOX inhibitors or catalase that reversed this effect. Furthermore, O3 caused the formation of SRB1-aldheyde adducts (4-hydroxy-2-nonenal) and the consequent increase of its ubiquitination, a mechanism that could account for SRB1 protein loss.

Abstract
Psoriasis is a hyperproliferative inflammatory skin disease; therefore, it is highly likely that psoriatic skin lesions may transform into malignancies. However, malignant transformation is not common. We performed immunohistochemical studies using anti‑cyclin D1, anti‑cyclin E, anti‑pRb, anti‑p53, anti‑p16INK4a, and anti‑Ki‑67 antibodies in normal skin, psoriatic epidermal tissue, and squamous cell carcinoma (SCC) tissue. Furthermore, western blot analysis and immunohistochemical staining were performed to ascertain differences in cyclin D1, cyclin E, pRb, and Ki‑67 expression before and after treatment for psoriasis. Cyclin D1 expression was higher in chronic psoriatic lesions than that in normal epidermis. Psoriasis lesions showed a strong intensity of positive nuclear staining for cyclin D1 among several normally stained nuclei in the basal layer. Cyclin E expression in psoriasis was stronger in the granular and spinous layer than in the normal epidermis. Expression levels of pRb and p53 were found to be higher in the psoriasis group compared with the normal epidermis. Total basal layer cell counts for p53WT expression were found to be significantly higher in the psoriasis group compared with the normal group. However, p16 expression was very weak in the normal and psoriasis groups compared with that in the SCC group. Ki‑67 immunoreactivity was significantly higher in psoriasis compared with normal epidermis and was similar with that in the SCC group. According to immunohistochemistry and immunoblot analysis, the expression levels of cyclin D1, cyclin E, pRb, and Ki‑67 in psoriasis lesions decreased after treatment and were similar with those in the normal group. Thus, increased expression of cyclin D1 and cyclin E may be involved in cell cycle progression in psoriatic epidermis, and pRb and p53 may play important roles in the prevention of malignant transformation under the hyperproliferative state in psoriasis.

Abstract
4-(Thiophen-2-yl)butanoic acid was identified as a cyclic substitute of the unsaturated alkyl chain of the natural ligand, capsaicin. Accordingly, a new class of amides was synthesized in good yield and high purity and their molecular recognition against the target was investigated by means of docking experiments followed by molecular dynamics simulations, in order to rationalize their geometrical and thermodynamic profiles. The pharmacological properties of these new compounds were expressed as activation (EC50) and desensitization (IC50) potencies. Several compounds were found to activate TRPV1 channels, and in particular, derivatives 1 and 10 behaved as TRPV1 agonists endowed with good efficacy as compared to capsaicin. The most promising compound 1 was also evaluated for its protective role against oxidative stress on keratinocytes and differentiated human neuroblastoma cell lines expressing the TRPV1 receptor as well as for its cytotoxicity and analgesic activity in vivo.

Abstract
Introduction One of the main functions of cutaneous tissues is to protect our body from the outdoor insults. Ozone (O3) is among the most toxic stressors to which we are continuously exposed and because of its critical location, the skin is one of the most susceptible tissues to the oxidative damaging effect of O3. O3 is not able to penetrate the skin, and although it is not a radical per se, the damage is mainly a consequence of its ability to induce oxidative stress via the formation of lipid peroxidation products. Aim of Study In this study we investigated the protective effect of defined “antioxidant” mixtures against O3 induced oxidative stress damage in human keratinocytes and understand their underlying mechanism of action. Results Results showed that the mixtures tested were able to protect human keratinocytes from O3-induced cytotoxicity, inhibition of cellular proliferation, decrease the formation of HNE protein adducts, ROS, and carbonyls levels. Furthermore, we have observed the decreased activation of the redox sensitive transcription factor NF-kB, which is involved in transcribing pro-inflammatory cytokines and therefore constitutes one of the main players associated with O3 induced skin inflammation. Cells exposed to O3 demonstrated a dose dependent increase in p65 subunit nuclear expression as a marker of NF-kB activation, while pre-treatment with the mixtures abolished NF-kB nuclear translocation. In addition, a significant activation of Nrf2 in keratinocytes treated with the mixtures was also observed. Conclusion Overall this study was able to demonstrate a protective effect of the tested compounds versus O3-induced cell damage in human keratinocytes. Pre-treatment with the tested compounds significantly reduced the oxidative damage induced by O3 exposure and this protective effect was correlated to the abolishment of NF-kB nuclear translocation, as well as activation of Nrf2 nuclear translocation activating the downstream defence enzymes involved in cellular detoxification process.

Abstract
BACKGROUND Resveratrol is a natural stilbene derivative whose chemopreventive activity has been well established. Our previous studies have shown that modification of the stilbene backbone with the methylthio group may influence selectivity and inhibitory potency toward P450 isozymes. The aim of this study was to further investigate the mechanism of their potential chemopreventive activity by evaluating the effect of two 4'-methylthio-trans-stilbene derivatives possessing one (3-M-4'-MTS; S2) and two (3,5-DM-4'-MTS; S5) additional methoxy groups on constitutive nuclear factor-κB (NF-κB) and activator protein-1 (AP-1) activation in immortalized human HaCaT keratinocytes. METHODS The synthesis of MTS was performed as described earlier. Translocation of NF-κB and AP-1 was evaluated by Western blot analysis. Binding of p65 (NF-κB) and c-Jun and c-Fos subunits (AP-1) to consensus oligonucleotide was assessed by ELISA. Real-time PCR and Western blot were used to evaluate COX-2 and iNOS expression. RESULTS We found differential modulation of signaling pathways depending on the stilbene structure after 24h of cells treatment. The S2 compound, in contrast to S5 and resveratrol, significantly reduced NF-κB activation by blocking the translocation of the p65 subunit to the nucleus, and decreasing IκB kinase activity. All compounds, but particularly S5, increased c-Jun binding to the AP-1 consensus sequence, while c-Fos binding was not affected. CONCLUSIONS We conclude that methylthiostilbenes differently modulate constitutive signal transduction pathways in HaCaT cells. These observations should be taken into account in designing new stilbene derivatives with potential chemopreventive activity.

Beta-actin deficiency with oxidative posttranslational modifications in Rett syndrome erythrocytes: insights into an altered cytoskeletal organization. PLoS One 2014; 9:e93181.

Abstract
Beta-actin, a critical player in cellular functions ranging from cell motility and the maintenance of cell shape to transcription regulation, was evaluated in the erythrocyte membranes from patients with typical Rett syndrome (RTT) and methyl CpG binding protein 2 (MECP2) gene mutations. RTT, affecting almost exclusively females with an average frequency of 1∶10,000 female live births, is considered the second commonest cause of severe cognitive impairment in the female gender. Evaluation of beta-actin was carried out in a comparative cohort study on red blood cells (RBCs), drawn from healthy control subjects and RTT patients using mass spectrometry-based quantitative analysis. We observed a decreased expression of the beta-actin isoforms (relative fold changes for spots 1, 2 and 3: −1.82±0.15, −2.15±0.06, and −2.59±0.48, respectively) in pathological RBCs. The results were validated by western blotting and immunofluorescence microscopy. In addition, beta-actin from RTT patients also showed a dramatic increase in oxidative posttranslational modifications (PTMs) as the result of its binding with the lipid peroxidation product 4-hydroxy-2-nonenal (4-HNE). Our findings demonstrate, for the first time, a beta-actin down-regulation and oxidative PTMs for RBCs of RTT patients, thus indicating an altered cytoskeletal organization.

Abstract
Psoriasis is a multifactorial inflammatory skin disease characterized by increased proliferation of keratinocytes, activation of immune cells and susceptibility to metabolic syndrome. Systems biology approach makes it possible to reveal novel important factors in the pathogenesis of the disease. Protein-protein, protein-DNA, merged (containing both protein-protein and protein-DNA interactions) and chemical-protein interaction networks were constructed consisting of differentially expressed genes (DEG) between lesional and non-lesional skin samples of psoriatic patients and/or the encoded proteins. DEGs were determined by microarray meta-analysis using MetaOMICS package. We used STRING for protein-protein, CisRED for protein-DNA and STITCH for chemical-protein interaction network construction. General network-, cluster- and motif-analysis were carried out in each network. Many DEG-coded proteins (CCNA2, FYN, PIK3R1, CTGF, F3) and transcription factors (AR, TFDP1, MEF2A, MECOM) were identified as central nodes, suggesting their potential role in psoriasis pathogenesis. CCNA2, TFDP1 and MECOM might play role in the hyperproliferation of keratinocytes, whereas FYN may be involved in the disturbed immunity in psoriasis. AR can be an important link between inflammation and insulin resistance, while MEF2A has role in insulin signaling. A controller sub-network was constructed from interlinked positive feedback loops that with the capability to maintain psoriatic lesional phenotype. Analysis of chemical-protein interaction networks detected 34 drugs with previously confirmed disease-modifying effects, 23 drugs with some experimental evidences, and 21 drugs with case reports suggesting their positive or negative effects. In addition, 99 unpublished drug candidates were also found, that might serve future treatments for psoriasis.
