There are currently no effective treatments for sepsis and acute respiratory distress syndrome (ARDS). The repositioning of existing drugs is one possible effective strategy for the treatment of sepsis and ARDS. We previously showed that vascular repair and the resolution of sepsis-induced inflammatory lung injury is dependent upon endothelial HIF-1α/FoxM1 signaling. The aim of this study was to identify a candidate inducer of HIF-1α/FoxM1 signaling for the treatment of sepsis and ARDS. Employing high throughput screening of a library of 1200 FDA-approved drugs by using hypoxia response element (HRE)-driven luciferase reporter assays, we identified Rabeprazole (also known as Aciphex) as a top HIF-α activator. In cultured human lung microvascular endothelial cells, Rabeprazole induced HIF1A mRNA expression in a dose-dependent manner. A dose-response study of Rabeprazole in a mouse model of endotoxemia-induced inflammatory lung injury identified a dose that was well tolerated and enhanced vascular repair and the resolution of inflammatory lung injury. Rabeprazole treatment resulted in reductions in lung vascular leakage, edema, and neutrophil sequestration and proinflammatory cytokine expression during the repair phrase. We next used Hif1a/Tie2Cre knockout mice and Foxm1/Tie2Cre knockout mice to show that Rabeprazole promoted vascular repair through HIF-1α/FoxM1 signaling. In conclusion, Rabeprazole is a potent inducer of HIF-1α that promotes vascular repair and the resolution of sepsis-induced inflammatory lung injury via endothelial HIF-1α/FoxM1 signaling. This drug therefore represents a promising candidate for repurposing to effectively treat severe sepsis and ARDS.

The influence of different proton pump inhibitors and potassium-competitive acid blockers on indomethacin-induced small intestinal injury was written by Li, Kemin;Cheng, Xiaoyun;Jin, Rui;Han, Taotao;Li, Jingnan. And the article was included in Journal of Gastroenterology and Hepatology in 2022.HPLC of Formula: 117976-90-6 The following contents are mentioned in the article:

Background and Aim : The influence of gastric acid inhibitors (GAIs) on nonsteroidal anti-inflammatory drug (NSAID)-induced enteropathy is controversial. Herein, the influences of different GAIs on NSAID-induced intestinal injury and the underlying mechanisms are clarified. Methods : Indomethacin (IND; 10 mg/kg/day) was administered to mice to induce small intestinal injury. Disease activity was examined macroscopically and histol. The permeability of small intestine was evaluated by measuring plasma lipopolysaccharide levels. 16S rDNA sequencing was performed to determine the composition of intestinal flora. Results : Among the four GAIs, ilaprazole (IPZ) significantly attenuated IND-induced small intestinal injury and maintained the integrity of the mucosal barrier. Omeprazole (OPZ) and vonoprazan (VPZ) ameliorated ulceration without significant differences, while rabeprazole (RPZ) failed to protect against the injury. To explore the potential mechanism, we investigated changes in the gut microbiota mediated by GAIs. After 5-day administration, GAIs significantly altered the composition of the gut microbiota. The IND group had a significant decrease in alpha diversity compared with the control group, and this decrease was reversed by OPZ and IPZ treatment, resp. After IPZ treatment, the community membership was more assembled in the control group than the IND group. Further, we found that Lactobacillus was significantly increased in the groups of OPZ, IPZ, and VPZ, while Bacteroides was significantly increased in the RPZ group. Conclusion : Our results indicated that GAIs have different influences on the mucosal barrier, possibly by altering the composition of intestinal microbiota, and the impacts mediated by various GAIs in the IND-induced intestinal damage model seem different.

Different dose of new generation proton pump inhibitors for the treatment of Helicobacter pylori infection: A meta-analysis was written by Gao, Wenwen;Zhang, Xiang;Yin, Yanhui;Yu, Shuwen;Wang, Lu. And the article was included in International Journal of Immunopathology and Pharmacology in 2021.COA of Formula: C18H20N3NaO3S The following contents are mentioned in the article:

The evidence on whether high-dose new generation proton pump inhibitors (PPIs) including rabeprazole and esomeprazole achieve a higher eradication rate of Helicobacter pylori has not been assessed. The primary comparison was eradication and adverse events (AEs) rate of standard (esomeprazole 20 mg bid, rabeprazole 10 mg bid) vs. high-dose (esomeprazole 40 mg bid, rabeprazole 20 mg bid) PPIs. Sub-analyses were performed to evaluate the eradication rate between Asians and Caucasians, clarithromycin-resistance (CAM-R) strains, and clarithromycin-sensitivity (CAM-S) strains of different dose PPIs. We conducted a literature search for randomized controlled trials comparing high-with standard-dose esomeprazole and rabeprazole for H. pylori eradication and AEs. A total of 12 trials with 2237 patients were included. The eradication rate of high-dose PPIs was not significantly superior to standard-dose PPIs regimens: 85.3% vs. 84.2%, OR 1.09 (0.86-1.37), P = 0.47. The high dose induced more AEs than those of the standard dose, but didn’t reach statistical significance (OR 1.25, 95% CI: 0.99-1.56, P = 0.06). Subgroup anal. showed that the difference in eradication rate of PPIs between high- and standard-dose groups were not statistically significant both in Asians (OR 0.99, 95% CI 0.75-1.32, P = 0.97) and Caucasians (OR 1.27, 95% CI 0.84-1.92, P = 0.26). Furthermore, there were similar eradication rates in CAM-S (OR 1.2; 95% CI 0.58-2.5; P = 0.63) and CAM-R strains (OR 1.08; 95% CI 0.45-2.56; P = 0.87) between the standard-and high-dose groups. High and standard dosages of new generation of the PPIs showed similar H. pylori eradication rates and AEs as well as between Asian vs. Caucasian populations, with or without clarithromycin-resistance. However, further studies are needed to confirm. This study involved multiple reactions and reactants, such as Sodium 2-(((4-(3-methoxypropoxy)-3-methylpyridin-2-yl)methyl)sulfinyl)benzo[d]imidazol-1-ide (cas: 117976-90-6COA of Formula: C18H20N3NaO3S).

Intestinal permeability and psychol. stress are considered the key mechanism(s) in functional dyspepsia (FD). Although proton pump inhibitors (PPIs) are commonly used for the treatment of FD, the effect of PPIs on intestinal permeability has not been elucidated. This study investigated the effect of PPI on intestinal permeability under stressed conditions. C57BL/6J mice were subjected to water avoidance stress (WAS) and administered rabeprazole (40 mg/kg) or vehicle treatment (VT). We then evaluated intestinal permeability both in vivo and ex vivo using plasma fluorescein isothiocyanate-dextran and by assessing the paracellular permeability and transepithelial elec. resistance (TEER) in an Ussing chamber, resp. Furthermore, we evaluated the effect of PPI-treated fecal microbiota transplant (FMT) on intestinal permeability in vivo. Microbiota profiles of donor feces were assessed by 16S rRNA gene anal. using MiSeq and QIIME2. In the WAS treatment, PPI significantly enhanced intestinal permeability in vivo compared to that in VT. Moreover, PPI significantly increased paracellular permeability and decreased TEER in the duodenum and jejunum, resp., compared to those in VT under stressed conditions. Moreover, both vasoactive intestinal peptide (VIP) receptor antagonist and ketotifen significantly reversed the effect of PPI on intestinal permeability. Furthermore, PPI-treated FMT significantly increased the intestinal permeability in vivo compared to that in vehicle-treated FMT. Proton pump inhibitors treatment altered the gut microbiota composition, indicating that PPI induced dysbiosis. Under stressed conditions, PPI enhances intestinal permeability via dysbiosis of gut microbiota. Vasoactive intestinal peptide and mast cells are also implicated in the underlying mechanisms.

Randomized trial of vonoprazan-based versus proton-pump inhibitor-based third-line triple therapy with sitafloxacin for Helicobacter pylori was written by Sue, Soichiro;Shibata, Wataru;Sasaki, Tomohiko;Kaneko, Hiroaki;Irie, Kuniyasu;Kondo, Masaaki;Maeda, Shin. And the article was included in Journal of Gastroenterology and Hepatology in 2019.Category: imidazoles-derivatives The following contents are mentioned in the article:

Background and Aim : This was a prospective, randomized trial of the efficacy of vonoprazan-based and proton-pump inhibitor-based 7-day triple regimens with amoxicillin and sitafloxacin as a third-line therapy for eradicating Helicobacter pylori after failure of clarithromycin-based and metronidazole-based first-line and second-line therapy. Methods : We enrolled 63 patients pos. for H. pylori in whom first-line and second-line regimens for eradicating failed. Patients were randomized to the V-AS group (vonoprazan 20-mg bid, amoxicillin 750-mg bid, and sitafloxacin 100-mg bid for 7 days) or PPI-AS group (esomeprazole 20-mg bid, rabeprazole 10-mg bid, or lansoprazole 30-mg bid; amoxicillin 750-mg bid; and sitafloxacin 100-mg bid for 7 days). We assessed the outcome of eradication therapy using the ¹³C-urea breath test. We evaluated safety using patient questionnaires. This study was registered in the UMIN Clin. Trials Registry (UMIN000016336). Results : The intention-to-treat and per-protocol eradication rates of V-AS were 75.8% (95% confidence interval [CI]: 57.7-88.9%) and 83.3% (95% CI: 65.3-94.4%), resp. The resp. eradication rates of PPI-AS were 53.3% (95% CI: 34.3-71.7%) and 57.1% (95% CI: 37.2-75.5%). In per-protocol analyses, the eradication rate of the V-AS group was significantly higher than that of the PPI-AS group (P = 0.043); however, no significant differences were observed in intention-to-treat analyses (P = 0.071). Questionnaire scores did not differ significantly between the groups. Conclusions : The findings suggest that 7-day triple therapy with vonoprazan, amoxicillin, and sitafloxacin is more effective than proton-pump inhibitor, amoxicillin, and sitafloxacin as a third-line regimen for eradicating H. pylori. This study involved multiple reactions and reactants, such as Sodium 2-(((4-(3-methoxypropoxy)-3-methylpyridin-2-yl)methyl)sulfinyl)benzo[d]imidazol-1-ide (cas: 117976-90-6Category: imidazoles-derivatives).

Rabeprazole has efficacy per se and reduces resistance to temozolomide in glioma via EMT inhibition was written by Babu, Deepak;Mudiraj, Anwita;Yadav, Neera;Y. B. V.

Epithelial to mesenchymal transition (EMT) is pivotal in embryonic development and wound healing, whereas in cancer it inflicts malignancy and drug resistance. The recognition of an EMT-like process in glioma is relatively new and its clin. and therapeutic significance has, as yet, not been fully elucidated. Here, we aimed to delineate the clin. significance of the EMT-like process in glioma and its therapeutic relevance to rabeprazole. We investigated the expression profiles of EMT-associated proteins in primary glioma biopsies through Western blotting and immunohistochem., and correlated them with various clinicopathol. features and data listed in the cancer genome atlas (TCGA). In addition, the anticancer efficacy of rabeprazole and its therapeutic relevance to EMT along with temozolomide chemo-sensitization were assessed using multiple cell-based assays, Western blotting and confocal imaging. For in vivo assessment, we used a stereotaxic C6-rat glioma model. Expression anal. of EMT-associated proteins in glioma biopsies, in conjunction with clinicopathol. and TCGA dataset analyses, revealed non-canonical expression of E/N-cadherin and upregulation of GFAP, vimentin and β-catenin. The increased expression of EMT-associated proteins may attribute to glioma malignancy and a poor patient prognosis. Subsequent in vitro studies revealed that rabeprazole treatment attenuated glioma cell growth and migration, and induced apoptosis. Rabeprazole suppressed EMT by impeding AKT/GSK3β phosphorylation and/or NF-κB signaling and sensitized temozolomide resistance. Addnl. in vivo studies showed restricted tumor growth and inhibited expression of EMT-associated proteins after rabeprazole treatment. Our data revealed (i) a clin. association of the EMT-like process with glioma malignancy and a poor survival and (ii) an anticancer and temozolomide sensitizing effect of rabeprazole by repressing EMT.

Developmental and Epileptic Encephalopathy (DEE) is a group of disorders affecting children at early stages of infancy, which is characterized by frequent seizures, epileptiform activity on EEG, and developmental delayor regression. Developmental and epileptic encephalopathy-30 (DEE30) is a severe neurol. disorder characterized by onset of refractory seizures soon after birth or in the first months of life. Which was recently found to be caused by heterozygous mutations in the salt-inducible kinase SIK1. In this study, we investigated a patient with early onset epilepsy. DNA sequencing of the whole coding region revealed a de novel heterozygous nucleotide substitution (c.880G > A) causing a missense mutation (p.A294T). This mutation was classified as variant of unknown significance (VUS) by American College of Medical Genetics and Genomics (ACMG). To further investigate the pathogenicity and pathogenesis of this mutation, we established a human neuroblastoma cell line (SH-SY5Y) stably-expressing wild type SIK1 and A294T mutant, and compared the transcriptome and metabolomics profiles. We presented a pediatric patient suffering from infantile onset epilepsy. Early EEG showed a boundary dysfunction of activity and MRI scan of the brain was normal. The patient responded well to single anti-epileptic drug treatment. Whole-exome sequencing found a missense mutation of SIK1 gene (c.880G > A chr21: 43,420,326 p. A294T). Dysregulated transcriptome and metabolome in cell models expressing WT and MUT SIK1 confirmed the pathogenicity of the mutation. Specifically, we found MEF2C target genes, certain epilepsy causing genes and metabolites are dysregulated by SIK1 mutation.

Purpose: Several retrospective studies have shown that the antitumor efficacy of capecitabine-containing chemotherapy decreases when co-administered with a proton pump inhibitor (PPI). Although a reduction in capecitabine absorption by PPIs was proposed as the underlying mechanism, the effects of PPIs on capecitabine pharmacokinetics remain unclear. We prospectively examined the effects of rabeprazole on the pharmacokinetics of capecitabine and its metabolites. Methods: We enrolled patients administered adjuvant capecitabine plus oxaliplatin (CapeOX) for postoperative colorectal cancer (CRC) patients and metastatic CRC patients receiving CapeOX with/without bevacizumab. Patients receiving a PPI before registration were allocated to the rabeprazole group, and the PPI was changed to rabeprazole (20 mg/day) at least 1 wk before the initiation of capecitabine treatment. On day 1, oral capecitabine (1000 mg/m2) was administered 1 h after rabeprazole intake. Oxaliplatin (and bevacizumab) administration on day 1 was shifted to day 2 for pharmacokinetic anal. of the first capecitabine dose. Plasma concentrations of capecitabine, 5-deoxy-5-fluorocytidine, 5-deoxy-5-fluorouridine, and 5-fluorouracil were analyzed by high-performance liquid chromatog. Effects of rabeprazole on inhibition of cell proliferation by each capecitabine metabolite were examined with colon cancer cells (COLO205 and HCT116). Results: Five and 9 patients enrolled between Sept. 2017 and July 2018 were allocated to rabeprazole and control groups, resp. No significant effects of rabeprazole on area under the plasma concentration-time curve divided by capecitabine dose for capecitabine and its three metabolites were observed Rabeprazole did not affect the proliferation inhibition of colon cancer cells by the resp. capecitabine metabolites.

Background and Aim : Most consensuses recommend culture-guided therapy as third-line Helicobacter pylori treatment. This study aimed to investigate the efficacies of culture-guided therapy and empirical therapy with high-dose proton pump inhibitor (PPI) in the H. pylori third-line treatment. Methods : Between August 2012 and Oct. 2021, H. pylori -infected patients with at least two failed eradication attempts received anti- H. pylori therapy according to the results of antimicrobial sensitivity tests plus high-dose rabeprazole and/or bismuth. They were categorized into three groups: patients who had pos. results of culture with equal to or more than three susceptible antibiotics were treated by culture-guided non-bismuth quadruple therapy, patients who had pos. results of culture with one or two susceptible antibiotics were treated by culture-guided bismuth-containing therapy, and patients who had a neg. result of culture were treated by an empirical therapy with high-dose rabeprazole plus amoxicillin, tetracycline and levofloxacin. A post-treatment assessment was conducted at week 8. Results : We recruited 126 patients. The eradication rates of culture-guided non-bismuth quadruple therapy (n = 50), culture-guided bismuth-containing therapy (n = 46) and empirical therapy (n = 30) were 84.0%, 87.0%, and 66.7% (95% confidence interval: 73.8-94.2%, 77.3-96.7%, and 49.8-83.6%), resp. Overall, culture-guided therapy achieved a higher eradication rate than empirical therapy (85.4% vs 66.7%; 95% confidence interval, 0.4% to 37.0%, P = 0.022). Conclusions : Culture-guided therapy with high-dose PPI achieves a higher eradication rate than empirical therapy with high-dose PPI in the third-line treatment of H. pylori infection. The eradication rate of rescue therapy with bismuth plus two susceptible antibiotics is not inferior to that with three susceptible antibiotics.

Detection of overdose and underdose prescriptions-An unsupervised machine learning approach was written by Nagata, Kenichiro;Tsuji, Toshikazu;Suetsugu, Kimitaka;Muraoka, Kayoko;Watanabe, Hiroyuki;Kanaya, Akiko;Egashira, Nobuaki;Ieiri, Ichiro. And the article was included in PLoS One in 2021.Formula: C18H20N3NaO3S The following contents are mentioned in the article:

Overdose prescription errors sometimes cause serious life-threatening adverse drug events, while underdose errors lead to diminished therapeutic effects. Therefore, it is important to detect and prevent these errors. In the present study, we used the one-class support vector machine (OCSVM), one of the most common unsupervised machine learning algorithms for anomaly detection, to identify overdose and underdose prescriptions. We extracted prescription data from electronic health records in Kyushu University Hospital between Jan. 1, 2014 and Dec. 31, 2019. We constructed an OCSVM model for each of the 21 candidate drugs using three features: age, weight, and dose. Clin. overdose and underdose prescriptions, which were identified and rectified by pharmacists before administration, were collected. Synthetic overdose and underdose prescriptions were created using the maximum and min. doses, defined by drug labels or the UpToDate database. We applied these prescription data to the OCSVM model and evaluated its detection performance. We also performed comparative anal. with other unsupervised outlier detection algorithms (local outlier factor, isolation forest, and robust covariance). Twenty-seven out of 31 clin. overdose and underdose prescriptions (87.1%) were detected as abnormal by the model. The constructed OCSVM models showed high performance for detecting synthetic overdose prescriptions (precision 0.986, recall 0.964, and F-measure 0.973) and synthetic underdose prescriptions (precision 0.980, recall 0.794, and F-measure 0.839). In comparative anal., OCSVM showed the best performance. Our models detected the majority of clin. overdose and underdose prescriptions and demonstrated high performance in synthetic data anal. OCSVM models, constructed using features such as age, weight, and dose, are useful for detecting overdose and underdose prescriptions. This study involved multiple reactions and reactants, such as Sodium 2-(((4-(3-methoxypropoxy)-3-methylpyridin-2-yl)methyl)sulfinyl)benzo[d]imidazol-1-ide (cas: 117976-90-6Formula: C18H20N3NaO3S).

Sodium 2-(((4-(3-methoxypropoxy)-3-methylpyridin-2-yl)methyl)sulfinyl)benzo[d]imidazol-1-ide (cas: 117976-90-6) belongs to imidazole derivatives. Imidazole derivatives generally have good solubility in protic solvents. Simple imidazole derivatives, such as 1H-imidazole, 2-methyl-1H-imidazole, and 1,2-dimethylimidazole, have very high solubility in water. Imidazole based anticancer drug find applications in cancer chemotherapy. It is used as buffer component for purification of the histidine tagged recombinant proteins in immobilized metal-affinity chromatography (IMAC).Formula: C18H20N3NaO3S
