In this paper, a series of artemisinin derivatives were synthesized and evaluated. Studies have shown that IFN-γ produced by Th1 CD4+ T cells and IL-17A secreted by Th17 CD4+ T cells played critical roles in the treatment of multiple sclerosis. We used different concentrations of artemisinin derivatives to inhibit Th1 / Th17 differentiation in naive CD4+ T cells and to characterize IFN-γ / IL-17A in in vitro experiments The preliminary screening results showed that ester compound 5 (I) exhibited obvious inhibitory activities on Th1 and Th17 (IFN-γ decreased from 41% to 3% and IL-17A decreased from 24% to 8% at the concentration of 10 nM to 10μM), and carbamate compounds also had obvious inhibitory activities against Th17 at high concentration Moreover, we investigated the effect of compound 5 on myelin oligodendrocyte glycoprotein (MOG)-induced mice exptl. autoimmune encephalomyelitis (EAE) model in vivo. 100 mg/kg compound 5 effectively reduced the disease severity of EAE compared with the vehicle group. This research revealed that compound 5 could be a promising avenue as potential MS inhibitor.

Klement, Rainer J.; Popp, Ilinca; Kaul, David; Ehret, Felix; Grosu, Anca L.; Polat, Buelent; Sweeney, Reinhart A.; Lewitzki, Victor published the artcile< Accelerated hyper-versus normofractionated radiochemotherapy with temozolomide in patients with glioblastoma: a multicenter retrospective analysis>, Reference of 112-63-0, the main research area is glioblastoma temozolomide HFRT NFRT survival MGMT hypermethylation IDH mutation; Accelerated hyperfractionation; Altered fractionation; Glioblastoma; Radiotherapy; Temozolomide.

The standard treatment of glioblastoma patients consists of surgery followed by normofractionated radiotherapy (NFRT) with concomitant and adjuvant temozolomide chemotherapy. Whether accelerated hyperfractionated radiotherapy (HFRT) yields comparable results to NFRT in combination with temozolomide has only sparsely been investigated. The objective of this study was to compare NFRT with HFRT in a multicenter anal. A total of 484 glioblastoma patients from four centers were retrospectively pooled and analyzed. Three-hundred-ten and 174 patients had been treated with NFRT (30 x 1.8 Gy or 30 x 2 Gy) and HFRT (37 x 1.6 Gy or 30 x 1.8 Gy twice/day), resp. The primary outcome of interest was overall survival (OS) which was correlated with patient-, tumor- and treatment-related variables via univariable and multivariable Cox frailty models. For multivariable modeling, missing covariates were imputed using multiple imputation by chained equations, and a sensitivity anal. was performed on the complete-cases-only dataset. After a median follow-up of 15.7 mo (range 0.8-88.6 mo), median OS was 16.9 mo (15.0-18.7 mo) in the NFRT group and 14.9 mo (13.2-17.3 mo) in the HFRT group (p = 0.26). In multivariable frailty regression, better performance status, gross-total vs. not gross-total resection, MGMT hypermethylation, IDH mutation, smaller planning target volume and salvage therapy were significantly associated with longer OS (all p < 0.01). Treatment differences (HFRT vs. NFRT) had no significant effect on OS in either univariable or multivariable anal. Since HFRT with temozolomide was not associated with worse OS, we assume HFRT to be a potential option for patients wishing to shorten their treatment time.

Qaid, Mohammed M.; Mansour, Lamjed; Al-Garadi, Maged A.; Alqhtani, Abdulmohsen H.; Al-abdullatif, Abdulaziz A.; Qasem, Mahmood A.; Murshed, Mutee A. published the artcile< Evaluation of the anticoccidial effect of traditional medicinal plants, Cinnamomum verum bark and Rumex nervosus leaves in experimentally infected broiler chickens with Eimeria tenella>, Electric Literature of 112-63-0, the main research area is CNB Rumex nervosus leaf broiler Eimeria tenella anticoccidial plant.

Rumex nervosus leaves (RNL) and Cinnamomum verum bark (CNB), phytogenic herbs, have received much attention in recent years for their antimicrobial properties; however, there is limited knowledge about their potential anticoccidial functions. The prophylactic effects of RNL and CNB were compared with salinomycin, a standard synthetic anticoccidial agent, in broilers exptl. infected with Eimeria tenella (E. tenella). One-day-old broiler chicks (n = 225) were randomly divided into nine groups. Birds were either fed a basal diet containing 1, 3, or 5 g RNL or 2, 4, or 6 g CNB/kg feed, or treated with salinomycin within the basal diet, or the infected (IUT) or non-infected (UUT) groups were fed a basal diet only. Birds infected (n = 25 bird/group) with 40,000 sporulated E. tenella oocysts/bird at d 21 except UUT. Bodweight gain (BWG) and feed conversion ratio (FCR) were significantly (p < .05) lower in IUT compared to UUT. On day 7 post-infection (DPI), birds treated with RNL, CNB, or salinomycin had fewer lesions in the caeca and a lower oocyst value, and a higher oocyst reduction rate in the faeces than birds in the IUT. Although RNL was not able to reduce weight loss caused by coccidiosis, CNB at 6 g improved FCR and production efficiency index (PEI) at 7 DPI compared to the infected groups. In conclusion, RNL at 5 g and CNB at 6 g have moderate anti-coccidial activity and could be used to treat poultry coccidiosis in the field. However, more research is needed to identify active ingredients that make it effective compared to com. available drugs. HIGHLIGHTSPhytogenic feed additives prevented weight loss and caecum pathol. in broiler chickens at risk of coccidiosis. Rumex nervosus leaves and Cinnamomum verum bark had similar effects to the coccidiostat salinomycin at high doses. Traditional medicinal plants are potential alternatives to pharmaceutical coccidiostats to promote the health and growth of broiler chickens.

Lustig, Samuel D.; Kodali, Sravan K.; Longo, Sharon L.; Kundu, Somanath; Viapiano, Mariano S. published the artcile< Ko143 reverses MDR in glioblastoma via deactivating P-glycoprotein, sensitizing a resistant phenotype to TMZ treatment>, Quality Control of 112-63-0, the main research area is reverses MDR glioblastoma deactivating P glycoprotein phenotype temozolomide treatment; BCRP; Ko143; P-glycoprotein; combinatorial treatment; drug resistance; temozolomide.

Over-expression of both P-glycoprotein (P-gp) and Breast Cancer Resistance Protein (BCRP) has been associated with multidrug-resistance in glioblastoma (GBM). Though previously studied broad-spectrum inhibitors of drug efflux pumps have failed to progress in clin. studies due to in vivo toxicity, research into clin. viable targeted inhibitors is needed. This study evaluated the effects of Ko143, a non-toxic analog of fumitremorgin C, on temozolomide (TMZ) efficacy in resistant glioblastoma stem cells. We used ATP-Glo assay to determine cell viabilities and flow cytometry to perform cell cycle anal. Comparative gene expression was analyzed through RT-qPCR. TMZ IC50 decreased 41.07% (p<0.01) in the resistant phenotype when delivered in combination with Ko143. Addnl., the TMZ-resistant phenotype (GBM146) displayed 44-fold greater P-gp expression than the TMZ-sensitive phenotype (GBM9) (p<0.01), yet a 0.6-fold lower BCRP expression. Ko143 potentiates TMZ efficacy and likely inhibits P-glycoprotein more potently than previously indicated. Further development of non-toxic, targeted inhibitors of drug efflux pumps for use in combinatorial chemotherapy may improve glioblastoma patient prognosis.

Hashimoto, Kei; Tatara, Ryoichi; Ueno, Kazuhide; Dokko, Kaoru; Watanabe, Masayoshi published the artcile< Design of polymer network and Li+ solvation enables thermally and oxidatively stable, mechanically reliable, and highly conductive polymer gel electrolyte for lithium batteries>, Application of C19H34O2, the main research area is design polymer network li solvation enables thermally oxidatively stable.

Herein, we demonstrate that design of polymer network and Li+-ion solvation enables the fabrication of thermally and oxidatively stable, mech. reliable, and highly conductive polymer gel electrolytes for lithium batteries. Polymer gel electrolytes have been used for Li-ion batteries (LIB) due to their quasi-solid natures and flexible shapes. However, they frequently suffer from the high vapor pressures of the incorporated solvents, low oxidative stabilities, and poor mech. properties. To overcome these drawbacks, we fabricated a tough gel electrolyte comprising a tetra-arm poly(ethylene glycol) (TPEG) homogeneous polymer network, in which a tetraglyme(G4)-based solvate ionic liquid (SIL) was incorporated. It was intriguing to find that the solvation of Li+ ion by oxygen atoms (within G4 and TPEG), represented as [O]/[Li], governed the thermal and oxidative stabilities of the gel electrolyte, while the homogeneous network contributed to the mech. reliability and high ionic conductivity At [O]/[Li] = 5, the TPEG-based gel electrolyte with no free solvent simultaneously exhibited high thermal (>200°C) and oxidative stabilities (>4.4 V), high stretchability, and high ionic conductivity (~1 mS cm-1 at 30°C). These favorable properties of the gel electrolyte resulted in reversible charge/discharge of a 4-V-class high-voltage cathode (LiNi0.6Mn0.2Co0.2O2, NMC622).

El-Rafie, Hanaa Mohamed; Zahran, Magdy K.; Raoof, Gehan F. Abdel published the artcile< Cotton bandages finished with microcapsules of volatile organic constituents of marine macro-algae for wound healing>, Reference of 112-63-0, the main research area is Cotton bandage microcapsulevolatile organic constituent marine macroalgae wound healing; Algal volatile constituents; Cotton fabric finishing; Gas chromatography/Mass spectrometry; Marine macroalgae; Microencapsulation; Wound healing.

Microencapsulation is an innovative technique having a growing application in textile finishing. Besides, marine macroalgae contain plenty of phytoconstituents used in various fields especially textile finishing. This work imparts the property of wound healing finish to cotton fabrics producing a bandage from eco-friendly algal volatile organic constituents (VOCs). VOCs extracted from Digenea simplex, Lurencea papillosa, Galaxurea oblongata, and Turbenaria decurrens Egyptian marine macroalgae scattered along the coastline of the Red sea were 0.52, 0.9, 0.87, and 0.62% (v/w), resp. These VOCs as well as their microencapsulated (VOM) forms were finished onto cotton fabrics by a conventional pad-dry cure technique using sodium alginate (SA) as a shell wall material. The VOCs of each alga were extracted and chem. investigated using gas chromatog. coupled with mass spectrometry (GC-MS). The results indicate, in addition to the identification of 125 volatile compounds, the diversity and outstanding differences in volatile composition among the 4 algae. Wound healing activities of the finished fabrics were evaluated. VOCs microcapsules-finished (VOMF) fabrics were more effective compared to VOCs-finished (VOF) fabrics and almost comparable to mebo-ointment (standard drug)-finished (MoF) fabrics. The differences in VOCs efficiencies may be attributable to the diversity in type and amount of volatiles found in the four algae. Therefore, this is a low-cost, convenient, reproducible, and scalable way to obtain encapsulated VOCs for the application in textile wound healing.

Nonmetallic ammonium (NH4+) ion batteries are promising candidates for large-scale energy storage systems, which have the merit of low molar mass, sustainability, non-toxicity and non-dendrite. Herein, for the first time, we introduce the novel organic ammonium ion batteries (OAIBs). Significantly, a manganese-based Prussian white analog (noted as MnHCF) as cathode exhibits a reversible capacity of 104 mAh g-1 with 98% retention over 100 cycles. We further demonstrate the electrochem. performance of the NH4+ ion full cell, which delivers a reversible capacity of 45 mAh g-1 with a broad electrochem. window. Combining ex situ XPS, ex situ XRD results and electrochem. properties, the NH4+ ion storage mechanism of MnHCF in a non-aqueous electrolyte is clearly revealed. This work verifies the feasibility of employing NH4+ ions as charge carriers in organic energy storage systems and provides new insights for designing organic nonmetallic ion batteries with broad electrochem. windows and high energy d.

In this manuscript a new organocatalytic approach to spirocyclic tetrahydrothiophenes bearing either a butenolide or an azlactone moiety is described. The developed methodol. is based on the cascade reactivity of 2-mercaptoacetaldehyde (generated in situ from 1,4-dithiane-2,5-diol) with α,β-unsaturated butenolides or azlactones, that consists of a thio-Michael addition followed by an intramol. aldol reaction. Chiral bases derived from cinchona alkaloids are used as a catalyst promoting the cascade and controlling its stereochem. outcome.
