Kim, Suyeon; Thapa, Ishwor; Zhang, Ling; Ali, Hesham published the artcile< On identifying candidates for drug repurposing for the treatment of ulcerative colitis using gene expression data>, HPLC of Formula: 6054-98-4, the main research area is gene expression antiinflammatory agent drug repurposing ulcerative colitis.

The notion of repurposing of existing drugs to treat both common and rare diseases has gained traction from both academia and pharmaceutical companies. Given the high attrition rates, massive time, money, and effort of brand-new drug development, the advantages of drug repurposing in terms of lower costs and shorter development time have become more appealing. Computational drug repurposing is promising approach and has shown great potential in tailoring genomic findings to the development of treatments for diseases. However, there are still challenges involved in building a standard computational drug repurposing solution for high-throughput anal. and the implementation to clin. practice. In this study, we applied the computational drug repurposing approaches for Ulcerative Colitis (UC) patients to provide better treatment for this disabling disease. Repositioning drug candidates were identified, and these findings provide a potentially effective therapeutics for the treatment of UC patients. This preliminary computational drug repurposing pipeline will be extended in the near future to help realize the full potential of drug repurposing.

Teruel, Adrian H.; Perez-Esteve, Edgar; Gonzalez-Alvarez, Isabel; Gonzalez-Alvarez, Marta; Costero, Ana M.; Ferri, Daniel; Gavina, Pablo; Merino, Virginia; Martinez-Manez, Ramon; Sancenon, Felix published the artcile< Double Drug Delivery Using Capped Mesoporous Silica Microparticles for the Effective Treatment of Inflammatory Bowel Disease>, Safety of Sodium 5,5′-(diazene-1,2-diyl)bis(2-hydroxybenzoate), the main research area is silica microparticle hydrocortisone inflammatory bowel disease antiinflammatory; colon targeted release; gated materials; inflammatory bowel disease; mesoporous silica microparticles; smart drug delivery materials.

Silica mesoporous microparticles loaded with both rhodamine B fluorophore (S1) or hydrocortisone (S2), and capped with an olsalazine derivative, are prepared and fully characterized. Suspensions of S1 and S2 in water at an acidic and a neutral pH show negligible dye/drug release, yet a notable delivery took place when the reducing agent sodium dithionite is added because of hydrolysis of an azo bond in the capping ensemble. Addnl., olsalazine fragmentation induced 5-aminosalicylic acid (5-ASA) release. In vitro digestion models show that S1 and S2 solids are suitable systems to specifically release a pharmaceutical agent in the colon. In vivo pharmacokinetic studies in rats show a preferential rhodamine B release from S1 in the colon. Moreover, a model of ulcerative colitis is induced in rats by oral administration of 2,4,6-trinitrobenzenesulfonic acid (TNBS) solutions, which was also used to prove the efficacy of S2 for colitis treatment. The specific delivery of hydrocortisone and 5-ASA from S2 material to the colon tissue in injured rats markedly lowers the colon/body weight ratio and the clin. activity score. Histol. studies showed a remarkable reduction in inflammation, as well as an intensive regeneration of the affected tissues.

Hakkou, Khalid; Molina-Pinilla, Inmaculada; Rangel-Nunez, Cristian; Suarez-Cruz, Adrian; Pajuelo, Eloisa; Bueno-Martinez, Manuel published the artcile< Synthesis of novel (bio) degradable linear azo polymers conjugated with olsalazine>, Product Details of C14H8N2Na2O6, the main research area is biodegradable linear conjugated olsalazine based polyazoester triazole preparation property.

Click Cu(I)-catalyzed polymerization of diynes and diazides was performed to obtain a novel type of linear copolymer, which were prepared from monomers derived from poly(ethylene glycol), 5,5′-azodisalicylic acid [olsalazine] and 1,4-butanediol diglycidyl ether. The resulting copolymers will carry ester and azo functions along the polymer backbone, so they will be sensitive to pH as well as be degraded by azoreductase enzymes present in the colonic microbiota. Most of the copoly(azoester triazole)s obtained were water soluble, and all of them were characterized by Fourier transform IR, NMR, and gel permeation chromatog.. Differential scanning calorimetry revealed them to be amorphous, and in general, the polymers were stable up to 250 °C under nitrogen as demonstrated by thermogravimetric anal.. The degradation behavior of the polymers was evaluated in vitro. Degradation studies were carried out at 37 °C in buffered salt solution at pH 7.4, and were monitored by GPC and NMR spectroscopies. A biodegradation experiment of a water-soluble prototype polymer showed that they are biodegradable via a strain of Enterococcus faecalis. The experiment was monitored using UV-visible spectroscopy.

McKay, G.; Kelly, J. C.; McConvey, I. F. published the artcile< The adsorption of pollutants from aqueous effluents using a two-resistance mass-transfer model>, HPLC of Formula: 6054-98-4, the main research area is phenol adsorption wastewater treatment model; dye adsorption wastewater treatment model.

The adsorption of various pollutants, such as PhOH, p-chlorophenol and different dyes, on to activated C and chitin (a high mol. weight polymer obtained from crustacea) was studied in an agitated batch system at a temperature of 18 ± 2°. Two methods were used to predict concentration decay curves and correlate theor. and exptl. data. Both methods are based on external mass transfer and internal diffusion as the controlling mass-transfer resistances. The 1st method is a rapid anal. solution enabling external mass-transfer coefficients and effective diffusivities to be determined, but is restricted to the assumption that a pseudo-anal. isotherm is applicable. The 2nd method, based on a pseudo-anal. solution, is applicable to operating lines and tie lines terminating at any point on the isotherm, but requires longer computational time. Values of mass-transfer coefficients and effective diffusivities are presented for all systems.

Pamukcu, Rifat; Hanauer, Stephen B.; Chang, Eugene B. published the artcile< Effect of disodium azodisalicylate on electrolyte transport in rabbit ileum and colon in vitro. Comparison with sulfasalazine and 5-aminosalicyclic acid>, Synthetic Route of 6054-98-4, the main research area is azodisalicylate electrolyte transport intestine; diarrhea azodisalicylate.

Azodisalicylate, used to treat ulcerative colitis, causes diarrhea in ≤12.5% of patients. The in vitro effects of azodisalicylate, sulfasalazine, and 5-aminosalicylic acid on rabbit intestinal electrolyte transport were studied. Distal ileal mucosae mounted in Ussing chambers were exposed to varying concentrations of the drugs. Mucosal addition of azodisalicylate (>5 mM) caused the greatest anion-dependent increase in short-circuit current of 83 μA/cm2. Isotope flux measurements suggest that azodisalicylate may stimulate predominantly electrogenic HCO3- secretion and induce net NaCl secretion. In contrast, serosal addition of azodisalicylate and sulfasalazine decreased short-circuit current, and 5-aminosalicylic acid had no effect. Azodisalicylate had no effect on ion transport in distal colon. The effects of azodisalicylate in ileum were not inhibited with piroxicam (an inhibitor of cyclooxygenase). Mucosal cAMP and cGMP levels were unchanged after ileal exposure to azodisalicylate. Azodisalicylate appears to be a mechanistically unusual secretagogue, possibly explaining the increased incidence of diarrhea seen in patients taking the drug.

Zhang, Huiping; Fan, Yaling; Krishna, Rajamani; Feng, Xuefeng; Wang, Li; Luo, Feng published the artcile< Robust metal-organic framework with multiple traps for trace Xe/Kr separation>, Synthetic Route of 6054-98-4, the main research area is metal organic framework adsorption direct separation simulation.

Direct separation of Xe and Kr from air or UNF off-gas by means of porous adsorbents is of industrial importance but is a very challenging task. In this work, we show a robust metal-organic framework (MOF), namely ECUT-60, which renders not only high chem. stability, but also unique structure with multiple traps. This leads to the ultrahigh Xe adsorption capacity, exceeding most reported porous materials. Impressively, this MOF also enables high selectivity of Xe over Kr, CO2, O2, and N2, leading to the high-performance separation for trace quantitites of Xe/Kr from a simulated UNF reprocessing off-gas. The separation capability has been demonstrated by using dynamic breakthrough experiments, giving the record Xe uptake up to 70.4 mmol/kg and the production of 19.7 mmol/kg pure Xe. Consequently, ECUT-60 has promising potential in direct production of Xe from UNF off-gas or air. The separation mechanism, as unveiled by theor. calculation, is attributed to the multiple traps in ECUT-60 that affords rigid restrict for Xe atom via van der Waals force.

Eriksson, A.; Nyholm, L. published the artcile< Coulometric and spectroscopic investigations of the oxidation and reduction of some azosalicylic acids at glassy carbon electrodes>, Safety of Sodium 5,5′-(diazene-1,2-diyl)bis(2-hydroxybenzoate), the main research area is coulometry spectroscopy oxidation reduction azosalicylic acid glassy carbon electrode.

Constant potential coulometry in combination with cyclic voltammetry, UV-visible, 1H and 13C NMR spectroscopy were used to identify the oxidation and reduction products for some structurally similar azosalicylic acids, including the azosalicylic drugs Sulfasalazine and Olsalazine. The experiments were carried out in aqueous solutions at pH 4.5 to 10.0. Voltammetric and UV-visible spectroscopic comparisons involving standard substances confirm that all compounds studied, except 4,4′-azobis[2-hydroxybenzoic acid], are reduced in an overall four-electron process to their corresponding amines. For 4,4′-azobis[2-hydroxybenzoic acid], the reduction involves only two electrons and most likely gives rise to the corresponding hydrazo compound The oxidations of 3,3′-azobis[6-hydroxybenzoic acid] (Olsalazine), 3,3′-azoxybis[6-hydroxybenzoic acid] and 2-hydroxy-5-[(3′-carboxy-2′-hydroxyphenyl)azo]benzoic acid involve an initial two-electron step. Based on UV and NMR spectroscopic data, probably the oxidation of 3,3′-azobis-[6-hydroxybenzoic acid] gives rise to a 2,2′-dicarboxy-1,4-dibenzoquinone azine.
