A series of Bronsted acidic ionic liquids based on N-methylimidazole cation [C₆mim] with different alkyl chain lengths and counter anions (HSO₄^–, H₂PO₄^–, CH₃COO^–) were synthesized. The structure and acidity of these ionic liquids were characterized, and the catalytic activities under different reaction conditions were investigated. The ionic liquid with HSO₄^– anion and alkyl chain length of C₆ attached to the cation exhibits the highest catalytic activity for bisphenol F (BPF) synthesis. Under the reaction conditions of temperature 90°C, reaction time 60 min, phenol/formaldehyde molar ratio 6:1 and catalyst/formaldehyde molar ratio 1:1, [C₆mim][HSO₄] shows excellent reaction activity with 80.5% yield and over 90% selectivity for bisphenol F synthesis. The ionic liquid was also found to have good reusability and low corrosion effects. These results suggest that the acidic ionic liquid [C₆mim][HSO₄] is a potential green approach to produce BPF.

Inhibition of monoglyceride lipase by proton pump inhibitors: investigation using docking and in vitro experiments was written by Dahabiyeh, Lina A.;Abu-rish, Eman Y.;Taha, Mutasem O.. And the article was included in Pharmacological Reports in 2020.SDS of cas: 117976-90-6 The following contents are mentioned in the article:

Currently, there is overwhelming evidence linking elevated plasma free fatty acids with insulin resistance and inflammation. Monoglyceride lipase (MGL) plays a crucial metabolic role in lipolysis by mediating the release of fatty acids. Therefore, inhibiting MGL should be a promising pharmacol. approach for treating type 2 diabetes and inflammatory disorders. Proton pump inhibitors (PPIs) have been reported to improve glycemic control in type 2 diabetes albeit via largely unknown mechanism. The anti-MGL bioactivities of three PPIs, namely, lansoprazole, rabeprazole, and pantoprazole, were investigated using docking experiments and in vitro bioassay. The three PPIs inhibited MGL in low micromolar range with rabeprazole exhibiting the best IC₅₀ at 4.2μM. Docking experiments showed several binding interactions anchoring PPIs within MGL catalytic site. Our study provides evidence for a new mechanism by which PPIs improve insulin sensitivity independent of serum gastrin. The three PPIs effectively inhibit MGL and, therefore, serve as promising leads for the development of new clin. MGL inhibitors. 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: 117976-90-6SDS of cas: 117976-90-6).

Human telomerase reverse transcriptase (hTERT) is broadly expressed in many cancers. High hTERT expression have been described in chronic lymphocytic leukemia (CLL). Here we investigated the relationship between anti-hTERT immunity and disease progression in 49 CLL patients. Anti-hTERT T cell responses were evaluated by IFNγ-ELISpot. Complementary flow cytometry analyses were performed, and data were analyzed in regards of the treatment received by CLL patients afterward and disease progression. Anti-hTERT responses were more frequently observed in non-progressive watch and wait patients, and in progressive patients scheduled to receive ibrutinib, as compared to patients scheduled to receive other types of treatment. In vitro, addition of the anti-PD-1 antibody nivolumab increased anti-hTERT responses. Importantly, Kaplan Meier analyses showed significantly longer progression-free survival in patients with anti-hTERT immune responses at diagnosis as compared to non-responder patients. Our results show that anti-hTERT T cell responses represent a new potential biomarker predictive of CLL clin. outcome.

An application of continuous flow microreactor in the synthesis and extraction of rabeprazole was written by Duan, Zhenya;Wang, Yan;Zhang, Ling;Cao, Xing;Fu, Lihua;Li, Zhenjiang;Zhang, Junmei. And the article was included in International Journal of Chemical Reactor Engineering in 2021.Category: imidazoles-derivatives The following contents are mentioned in the article:

The oxidation of rabeprazole sulfide is a key step in the synthesis of rabeprazole, a drug for the treatment of stomach acid-related disorders. The current rabeprazole production process adopts one pot batch process, which has low reaction efficiency and poor stability. A continuous process can greatly improve the production efficiency and solve the above problems. Therefore, the reaction parameters of rabeprazole in microreactor were explored through laboratory experiments to explore the possibility of continuous production of rabeprazole. Rabeprazole sodium was synthesized by using rabeprazole thioether as a raw material and sodium hypochlorite solution as the oxidant. Oxidation, quenching, acid-base regulation and extraction were completed continuously in the microreactor. Rabeprazole solution with a purity of 98.78% (±0.13%) can be obtained continuously in 56 s, whereas intermittent production lasted for at least 2 h. Thus, the microreactor can effectively improve the oxidation synthesis efficiency of rabeprazole, and provide reference for the realization of other reactions in the microreactor. 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).

A review. Bendamustine is an alkylating agent classified into the group of nitrogen mustard analogs, synthesized almost sixty years ago. It was registered in former East Germany in 1971 and approved by the US Food and Drug Administration in 2008 for treatment of chronic lymphocytic leukemia and indolent B-cell non-Hodgkin lymphoma. Considering its beneficial properties in the therapy of relapsed or refractory hematol. malignancies, synergistic effects with other antineoplastic agents and increasing recent reports on its immunomodulatory effects, bendamustine has once again gained its justified attention. The uniqueness of bendamustine-mediated effects should be observed keeping in mind its distinctive structure with structural similarities to both alkylating agents and purine analogs. In the present review, the current knowledge on the use of bendamustine in oncol., its pharmacokinetics, mechanism of action and toxicity was summarized. In addition, its immune-modulating effects that have not been fully elucidated so far are emphasized, hoping to encourage further investigations of this unique drug.

Poly(ethylene oxide), PEO, or poly(vinylidenefluoride-co-hexafluoropropene) (PVDF-HFP), and the ionic liquids 1-n-propyl-2,3-dimethylimidazolium tetrafluoroborate (MMPIBF₄) and 1-n-propyl-2,3-dimethylimidazolium hexafluorophosphate (MMPIPF₆) with and without 0.5 M Li salt were used to prepare solid polymer gel electrolytes. Experimentation indicated that for the PEO films, the 20 and 30 weight% polymer gels exhibited the highest ionic conductivity, although the 20 weight% film is fragile and exhibits poor mech. properties. Therefore, the composition of all gels studied is 30 weight% polymer and 70 weight% ionic liquid For all systems, addition of the lithium salts results in approx. a 33% drop in ionic conductivity For the formation of polymer gel electrolytes, selection of a nonpolar polymer paired with a hydrophobic electrolyte results in greater ionic conductivity and reversibility in the intercalation of Li ion into graphite.

The incorporation of novel agents including immunomodulatory drugs(IMiDs), proteasome inhibitors (PIs), and monoclonal antibodies (mAbs) to myeloma treatment regimens have led to substantial gains in overall survival in patients with multiple myeloma over the last 10-15 years. However, alkylating agents remain an important option in the myeloma therapeutic armamentarium, and their use in combination with novel agents have shown to be an effective treatment strategy for both newly diagnosed and relapsed and/or refractory myeloma patients. The primary endpoint of the study was to determine the MTD of carfilzomib, bendamustine and dexamethasone with dose-limiting toxicities (DLTs) assessed during the cycle one (28-day) DLT-evaluable period. In summary, we establish the MTD of the combination of carfilzomib, bendamustine, and dexamethasone in RRMM and demonstrate its encouraging preliminary efficacy in this phase one study.
