A reversed-phase ion-pair chromatog. method using direct conductivity detection was developed for the determination of hexafluorophosphate(PF6) ionic liquid anion. Chromatog. separation was performed on a Diamonsil C18 reversed-phase column using ion-pair reagent-citric acid-acetonitrile as mobile phase. The effects of ion-pair reagent, volume fraction of acetonitrile, pH and column temperature on the retention factor and separation of PF6 were investigated. The mechanism of retention in the separation was discussed. The optimized chromatog. conditions for the determination of PF6 were using 0.05 mmol/L tetrabutylammonium hydroxide(TBAH)-0.038 mmol/L citric acid-35% acetonitrile(pH 5.5) as mobile phase, at a flow rate of 1.0 mL/min and a column temperature of 40°C. Under the optimal conditions, the retention time of PF6 was less than 15 min and the baseline separation of PF6 was achieved without any interference by other common anions(Cl, NO3, F, Br, SO-24 and BF4). The detection limit(S/N=3) for PF6 was 0.25 mg/L. The good linear relationship was obtained between chromatog. peak area and concentration of PF6 in the range of 0.5-100.0 mg/L. The relative standard deviations(RSD, n=5) of chromatog. peak area and retention time were 0.17% and 0.15%, resp. The proposed method was applied in the determination of PF6 in ionic liquids of 1-butyl-3-methylimidazolium hexafluorophosphate and 1-propyl-2, 3-dimethylimidazolium hexafluorophosphate. The spiked recoveries of PF6 were 99% and 104%, resp. The good linearity and repeatability of the method could meet the requirements for the quant. anal. of PF6 in ionic liquids The method is simple, accurate, reliable and practical.

Background: Behcet’s disease (BD) is a chronic immune disease that involves multiple systems. As the pathogenesis of BD is not clear, and new treatments are needed, we used bioinformatics to identify potential drugs and validated them in mouse models. Methods: Behcet’s disease-related target genes and proteins were screened in the PubMed and UVEOGENE databases. The biol. functions and pathways of the target genes were analyzed in detail by Gene Ontol. (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses. A protein-protein interaction (PPI) network was constructed by the STRING database, and hub genes were identified by the Cytoscape plug-in CytoHubba. Gene-drug interactions were identified from the DGIdb database. Exptl. autoimmune uveitis (EAU) mice were used as an animal model for drug validation. Results: A total of 249 target genes and proteins with significant differences in BD were screened, and the results of functional enrichment anal. suggested that these genes and proteins were more located on the cell membrane, involved in regulating the production of cytokines and affecting the activity of cytokines. They mainly regulated “Cytokine- Cytokine receptor interaction”, “Inflammatory bowel disease (IBD)” and “IL-17 signaling Pathway”. In addition, 10 hub genes were obtained through PPI network construction and CytoHubba anal., among which the top 3 hub genes were closely related to BD. The DGIdb anal. enriched seven drugs acting together on the top 3 hub genes, four of which were confirmed for the treatment of BD or its complications. There is no evidence in the research to support the results in omeprazole, rabeprazole, and celastrol. However, animal experiments showed that rabeprazole and celastrol reduced anterior chamber inflammation and retinal inflammation in EAU mice. Conclusions: The functional anal. of genes and proteins related to BD, identification of hub genes, and validation of potential drugs provide new insights into the disease mechanism and potential for the treatment of BD.

Chimeric antigen receptor T cell (CAR-T) therapy has emerged as highly effective in relapsed/refractory (R/R) diffuse large B-cell lymphoma (DLBCL), but only about 40% patients have achieved sustained responses. Here, we conducted a phase II clin. trial testing efficacy and toxicities of CAR-T therapy in R/R non-Hodgkin’s lymphoma patients (NCT03196830). Among enrolled patients, 33 R/R DLBCL patients pretreated with DFC (decitabine, fludarabine plus cyclophosphamide) lymphodepletion chemotherapy and infused with tandem CD19-CD22 based CAR-T cells were drawn out for efficacy and toxicities of CAR-T therapy evaluation. With a median follow-up of 10.9(0.6-29.0) months, the best overall response and complete remission (CR) rates were 90.9% and 63.6%, resp. The median progression-free survival (PFS) was 10.2 mo and overall survival (OS) was undefined. The 2- year OS and PFS rates were 54.3% and 47.2%, resp. No severe grade 4 cytokine release syndrome (CRS) was observed and grade 3 CRS was observed in only 7 patients; 3 patients developed mild immune effect or cell-associated neurotoxic syndrome. All toxicities were transient and reversible and no CART-related mortality. Further subgroup anal. showed that achieving CR was an independent prognostic factor associated with favorable PFS and OS. The 2- year OS and PFS for patients who achieved CR within 3 mo (undefined vs. undefined P = 0.021 and undefined vs. undefined P = 0.036) or during the follow-up period were significantly longer than those who did not (undefined vs. 4.6 mo P < 0.0001 and undefined vs. 2.0months P<0.001). While severe CRS was also an independent prognostic factor but associated with inferior PFS and OS. The 2-yr OS and PFS for patients with grade 3 CRS were significantly shorter than those with grade 0-2 CRS (4.1 mo vs. undefined P<0.0001 and 1.7 mo vs. undefined P = 0.0002). This study indicated that CD19/CD22 dual-targeted CAR-T therapy under a decitabine-containing lymphodepletion regimen may be a safe, potent effective approach to R/R DLBCL patients.

Under the direction of large conjugated organic species, a series of novel iodobismuthates(III), [Me3BIP][BiI6] (1, Me3BIP = N,N’,N”-trimethyl-3,5-bis(imidazole-1-yl)pyridine), [Me3BIP][Bi2I9] (2), [Me3TIP][Bi2I9] (3, Me3TIP = N,N’,N”-trimethyl-tris[4-(1H-imidazole-1-yl)-phenyl]amine), and [Me3TIB][Bi2I9] (4, Me3TIB = N,N’,N”-trimethyl-1,3,5-tris(1-imidazolyl)benzene), were synthesized via the solvothermal method. These iodobismuthates display two types of structures: 1 contains a [BiI6]3- monometallic unit, and 24 possess binuclear [Bi2I9]3- clusters, which are formed by two BiI6 octahedra via face-sharing. The reactants BIP, TIP, and TIB were in situ transformed into [Me3BIP]3+ in 1 and 2, [Me3TIP]3+ in 3, and [Me3TIB]3+ in 4 through the direct N-methylation reaction. UV-visible spectra analyses imply that all compounds possess potential semiconductor properties with narrow band gaps of 2.14, 2.02, 2.09, and 2.07 eV for 14, resp. Compound 3 has high visible-light-driven photocatalytic degradation activity and good recyclability to organic pollutants. Radical trapping experiments combined with theor. calculations show that the conjugated organic cations contribute to the narrow band gaps of the semiconductors, which can efficiently restrain the recombination of photogenerated electron-hole pairs, resulting in a good photocatalytic efficiency and stability under visible-light irradiation It is expected that the work will shed useful insights in exploitation of novel halometallates with narrow energy gaps by employing large conjugated organic templates.

BACKGROUND AND OBJECTIVE: Concurrent usage of proton pump inhibitors and their effect on survival and medication termination has been found in individuals receiving protein kinase inhibitor chemotherapy. To investigate the drug-drug interaction mechanism between CDK inhibitors and proton pump inhibitors, the in-silico docking approach was designed by applying computer simulation modules to predict the binding and inhibitory potential. METHODS: The interaction potential of proton pump inhibitors and CDK inhibitors was predicted utilising molecular docking techniques that employed Schrödinger algorithms to capture the dynamics of the CYP450 enzyme-inhibitor interaction between proton pump inhibitors and CDK inhibitors. Additionally, the human liver microsomes assay was used to determine the in vitro half-maximal inhibitory concentration (IC50) of proton pump inhibitors and the inactivation of CDK inhibitors via CYP3A4. RESULTS: Proton pump inhibitors alter the conformation of the CYP3A4 and CYP2C19 enzymes and interact with the heme prosthetic group, as determined by docking studies. It may result in the suppression of CDK inhibitors’ metabolism via competitive inhibition at the binding site of an enzyme. Omeprazole and rabeprazole both significantly block midazolam’s 1′-hydroxylation by CYP3A4 in vitro, with IC50 values of 9.86μM and 9.71μM, respectively. When omeprazole and rabeprazole are co-incubated in human liver microsomes at a 30μM concentration equivalent to the Cmax of omeprazole and rabeprazole, rabeprazole significantly prolongs the metabolic clearance of palbociclib, whereas omeprazole affects the ribociclib CYP3A4-mediated metabolism. CONCLUSION: Using dynamic models, we determined that proton pump inhibitors such as rabeprazole and omeprazole indeed have the potential to cause clinically significant drug-drug interactions with CDK inhibitors in the treatment of estrogen receptor (ER) positive and HER2-positive breast cancer. As a result, it is suggested to use caution when prescribing proton pump inhibitors to these individuals.

Obinutuzumab, a Type II anti-CD20 antibody, is used to treat follicular lymphoma. A major mode of action of obinutuzumab is antibody-dependent cellular cytotoxicity (ADCC). Knowledge of the mechanisms of resistance to obinutuzumab is important for the development of next-line strategies to follow obinutuzumab-containing therapy, including obinutuzumab retreatment. Unfortunately, the mechanisms by which tumor cells acquire resistance to ADCC are still poorly understood. To address this, we examined the mechanisms of resistance to obinutuzumab-induced ADCC and the combination efficacy of obinutuzumab and clin. available agents in the established resistant cells. Methods and results: We established cells resistant to obinutuzumab-induced ADCC using the non-Hodgkin lymphoma cell line RL and examined their mechanisms of resistance and the combination efficacy of obinutuzumab and clin. available agents. Comprehensive anal. by RNA sequencing of resistance mechanisms revealed that abnormal Fas signaling decreased sensitivity to ADCC in resistant clones. Combination treatment with prednisolone, a component of CHOP and CVP, was found to enhance ADCC sensitivity of RL cells and resistant clones and to significantly suppress tumor growth in xenograft models. Treatment with prednisolone upregulated expression of CD20 and an apoptosis-inducing protein BIM, which might augment perforin/granzyme B-mediated cell death. Furthermore, pretreatment of the effector cells with bendamustine enhanced ADCC activity, and treatment with obinutuzumab plus bendamustine showed significant antitumor efficacy in xenograft models. It was speculated that bendamustine upregulates ADCC activity by potentiating granules-mediated cell killing. Our study revealed a novel mechanism underlying obinutuzumab-induced ADCC resistance and indicated that ADCC resistance could be overcome by combining obinutuzumab with prednisolone or bendamustine. This study provides a scientific rationale for obinutuzumab-retreatment in combination with clin. available chemotherapeutic agents for obinutuzumab resistant follicular lymphoma.

The 2HEAA IL is almost 10 times more viscous than the (HMIM)HSO4 IL. The anodes developed were electrochem. characterized by cyclic voltammetry, morphol. factor, electrochem. impedance spectroscopy and accelerated service lifetime tests. The electrodes synthesized using the 2HEAA IL have superior electrocatalytic properties and electrochem. stability than those made using the (HMIM)HSO4 IL. In addition, the anodes made using the 2HEAA IL as solvent have more homogenous surfaces and higher crystallinity degree than those made using the (HMIM)HSO4 IL. Among the studied calcination temperatures, combining 550 °C and the 2HEAA IL results in more compact and rough electrode surfaces with the highest electroactive areas and electrochem. stability. Thus, the temperature of 550 °C is suitable for the synthesis of mixed metal oxide (MMO) anodes. The electrodes synthesized using the 2HEAA IL are more efficient in the electrochem. oxidation of the Reactive Yellow 186 dye than those made using the (HMIM)HSO4 IL. Consequently, the viscosity of the IL used has great influence on the performance of the synthesized anodes. In addition, the high viscosity of the 2HEAA IL results in a lower number of calcinations steps to produce the anodes and, hence, lower production cost. Viscous ionic liquids are therefore promising for the production of MMO anodes via thermal decomposition methods. This study involved multiple reactions and reactants, such as 1-Hexyl-3-methyl-1H-imidazol-3-ium hydrogensulfate (cas: 478935-29-4Formula: C10H20N2O4S).

1-Hexyl-3-methyl-1H-imidazol-3-ium hydrogensulfate (cas: 478935-29-4) belongs to imidazole derivatives. Among the different heterocyclic compounds, imidazole is better known due to its broad range of chemical and biological properties. Imidazole has become an important synthon in the development of new drugs. Imidazole also acts as a microtubule destabilizing agents and inhibits topoisomerase and Cytochrome P450 Family 26 Subfamily A Member 1 (CYP26A1) enzymes.Formula: C10H20N2O4S

Chronic lymphoblastic leukemia (CLL) is the most common adult leukemia and mainly affects the elderly. Chemoimmunotherapy still has a role in the standard frontline therapy for specific population. However, the clin. activity of bendamustine has not been investigated in unfit Chinese patients with CLL. To compare the efficacy and safety of bendamustine vs. chlorambucil for untreated Chinese patients with Binet stage B/C CLL. Methods. In this multi-center, randomized, open-label, parallel-controlled, phase III trial, patients with previously untreated CLL were enrolled and randomly assigned (1:1) to receive bendamustine or chlorambucil. The primary endpoint was the objective response rate. Secondary endpoints included progression-free survival, the duration of response, and overall survival. Adverse events were recorded to evaluate safety. Of 158 screened patients, 147 were enrolled and randomly allocated to receive bendamustine (n = 72) or chlorambucil (n = 75). After a median follow-up of 25.6 mo (IQR 12.5-27.7), 69.0% (95% CI, 56.9-79.5) of bendamustine-treated patients achieved objective response and 37.0% (95% CI, 26.0-49.1) of chlorambucil with a difference of 32.0% (95%CI: 16.6-47.5), demonstrating the superiority of bendamustine to chlorambucil (p < 0.001). The median progression-free survival was longer for bendamustine (16.5 mo; 95% CI, 11.3-24.7) vs. chlorambucil (9.6 mo; 95% CI, 8.7-11.8; p < 0.001). A longer median duration of response was seen in those receiving bendamustine (19.2 mo; 95% CI, 11.8-29.1) than chlorambucil (10.7 mo; 95% CI, 5.6-13.6; p = 0.0018). Median overall survival was not reached in either group. Overall survival at 18 mo was 88% for bendamustine vs. 85% for chlorambucil. Most common adverse events in both groups were neutropenia and thrombocytopenia. In untreated Chinese patients with Binet stage B/C CLL, bendamustine induced the better objective response and resulted in longer progression-free survival than chlorambucil. Overall, these results validate the role of bendamustine as an effective and safe first-line therapy in this population.

Despite impressive progress, a significant portion of patients still experience primary or secondary resistance to chimeric antigen receptor (CAR) T-cell immunotherapy for relapsed/refractory diffuse large B-cell lymphoma (r/r DLBCL). The mechanism of primary resistance involves T-cell extrinsic and intrinsic dysfunction. In the present study, a total of 135 patients of DLBCL treated with murine CD19/CD22 cocktail CAR T-therapy were assessed retrospectively. Based on four criteria (maximal expansion of the transgene/CAR-pos. T-cell levels post-infusion [Cmax], initial persistence of the transgene by the CAR transgene level at +3 mo [Tlast], CD19+ B-cell levels [B-cell recovery], and the initial response to CAR T-cell therapy), 48 patients were included in the research and divided into two groups (a T-normal group [n = 22] and a T-defect [n = 26] group). According to univariate and multivariate regression analyses, higher lactate dehydrogenase (LDH) levels before leukapheresis (hazard ratio (HR) = 1.922; p = 0.045) and lower cytokine release syndrome (CRS) grade after CAR T-cell infusion (HR = 0.150; p = 0.026) were independent risk factors of T-cell dysfunction. Moreover, using whole-exon sequencing, we found that germline variants in 47 genes were significantly enriched in the T-defect group compared to the T-normal group (96% vs. 41%; p<0.0001), these genes consisted of CAR structure genes (n = 3), T-cell signal 1 to signal 3 genes (n = 13), T cell immune regulation- and checkpoint-related genes (n = 9), cytokine- and chemokine-related genes (n = 13), and T-cell metabolism-related genes (n = 9). Heterozygous germline UNC13D mutations had the highest intergroup differences (26.9% vs. 0%; p = 0.008). Compound heterozygous CX3CR1I249/M280 variants, referred to as pathogenic and risk factors according to the ClinVar database, were enriched in the T-defect group (3 of 26). In summary, the clin. characteristics and T-cell immunodeficiency genetic features may help explain the underlying mechanism of treatment primary resistance and provide novel insights into CAR T-cell immunotherapy.
