Yasunaga, Katsuaki; Kiyonari, Akiko; Nakagawa, Munehiro; Yoshikawa, Kunie published the artcile< Investigation into the ability of the Salmonella umu test to detect DNA damage using antitumor drugs>, Safety of 2-(Bis(2-chloroethyl)amino)-1,3,2-oxazaphosphinane 2-oxide hydrate, the main research area is antitumor genotoxicity Salmonella umu gene.

In order to examine the ability of the umu test detecting system, 18 antitumor drugs were tested using the Salmonella umu test. The tested antitumor drugs were selected so as to produce different biochem. actions, and they were classified into three categories; five agents of group I (antimetabolites), eight agents of group II (alkylating agents), and five agents of group III (antibiotics). The results showed that all antimetabolites, all alkylating agents, and three of the antibiotics had pos. responses, but the antibiotics aclarubicin (ACR) and chromomycin A3 (CHR) had neg. responses. Both antibiotics that gave neg. responses were anthracyclines, but daunomycin (DNR), which was one of the anthracyclines, had a pos. result in the umu test. These results suggest that it is possible for the umu test to detect genotoxicity of chems. regardless of the types of DNA damage (inhibition of DNA synthesis relative enzyme, DNA base alkylating, DNA strand-break, and DNA adduct), but difficult for it to detect genotoxicity of any anthracyclines.

Ageberg, Malin; Rydstroem, Karin; Linden, Ola; Linderoth, Johan; Jerkeman, Mats; Drott, Kristina published the artcile< Inhibition of geranylgeranylation mediates sensitivity to CHOP-induced cell death of DLBCL cell lines>, HPLC of Formula: 6055-19-2, the main research area is anticancer geranylgeranyl transferase inhibitor chemosensitivity apoptosis B cell lymphoma.

Prenylation is a post-translational hydrophobic modification of proteins, important for their membrane localization and biol. function. The use of inhibitors of prenylation has proven to be a useful tool in the activation of apoptotic pathways in tumor cell lines. Rab geranylgeranyl transferase (Rab GGT) is responsible for the prenylation of the Rab family. Overexpression of Rab GGTbeta has been identified in CHOP refractory diffuse large B cell lymphoma (DLBCL). Using a cell line-based model for CHOP resistant DLBCL, we show that treatment with simvastatin, which inhibits protein farnesylation and geranylgeranylation, sensitizes DLBCL cells to cytotoxic treatment. Treatment with the farnesyl transferase inhibitor FTI-277 or the geranylgeranyl transferase I inhibitor GGTI-298 indicates that the reduction in cell viability was restricted to inhibition of geranylgeranylation. In addition, treatment with BMS1, a combined inhibitor of farnesyl transferase and Rab GGT, resulted in a high cytostatic effect in WSU-NHL cells, demonstrated by reduced cell viability and decreased proliferation. Co-treatment of BMS1 or GGTI-298 with CHOP showed synergistic effects with regard to markers of apoptosis. We propose that inhibition of protein geranylgeranylation together with conventional cytostatic therapy is a potential novel strategy for treating patients with CHOP refractory DLBCL.

A solid-phase extraction (SPE) LC-MS/MS method for 18 com. drugs in secondary wastewater and product water from water recycling plants using microfiltration (MF) and reverse osmosis (RO) has been developed, optimized and validated. The method incorporates a range of multi-class pharmaceuticals including lipid lowering agents, analgesics, antipyretics, non-steroidal anti-inflammatory drugs, antidepressants, anticoagulants, tranquilizers, cytostatic agents, and antiepileptics. Method limits of quantitation (MLQs) in secondary wastewater were 15-250 ng/L, while MLQs in post-RO water were 1-25 ng/L. Results from anal. of secondary wastewater from Western Australia are presented, and represent the largest survey of non-antibiotic pharmaceuticals within Australia to date. Anal. of post-RO water from 2 MF/RO water recycling facilities also demonstrate that MF/RO treatment removes most pharmaceuticals to below the anal. limits of detection, and more importantly, ≤7 orders of magnitude below health-based guideline values.

Pan, Jingwen; Guan, Zhongjie; Yang, Jianjun; Li, Qiuye published the artcile< Facile fabrication of ZnIn2S4/SnS2 3D heterostructure for efficient visible-light photocatalytic reduction of Cr(VI)>, Product Details of Cl3H8InO4, the main research area is tin zinc indium sulfide chromium heterostructure light photocatalytic reduction.

Photocatalytic method has been intensively explored for Cr(VI) reduction owing to its efficient and environmentally friendly natures. In order to obtain a high efficiency in practical application, efficient photocatalysts need to be developed. Here, ZnIn2S4/SnS2 with a three-dimensional (3D) heterostructure was prepared by a hydrothermal method and its photocatalytic performance in Cr(VI) reduction was investigated. When the mass ratio of SnS2 to ZnIn2S4 is 1:10, the ZnIn2S4/SnS2 composite exhibits the highest photocatalytic activity with 100% efficiency for Cr(VI) (50 mg/L) reduction within 70 min under visible-light irradiation, which is much higher than those of pure ZnIn2S4 and SnS2. The enhanced charge separation and the light absorption have been confirmed from the photoluminescence and UV-vis absorption spectra to be the two reasons for the increased activity towards photocatalytic Cr(VI) reduction In addition after three cycles of testing, no obvious degradation is observed with the 3D heterostructured ZnIn2S4/SnS2, which maintains a good photocatalytic stability.

Fischer, A.; Koeper, L. M.; Vohr, H.-W. published the artcile< Specific antibody responses of primary cells from different cell sources are able to predict immunotoxicity in vitro>, Quality Control of 6055-19-2, the main research area is immunotoxicity test antibody spleen PBMC cell.

Alternative methods for the prediction of immunotoxicity are highly desirable. However, until now no in vitro test for this purpose has been fully validated or accepted by regulatory authorities. MD cultures are in vitro equivalent to the widely used ex vivo primary T cell dependent antibody responses (TDAR), which has been identified in a regulatory context as a main functional test for immunotoxicol. investigations. The purpose of the present study was to use MD cultures of spleen and blood cells to compare data from three different chems. using SRBC as antigen in two different species. Using this approach we were able to show that cell sources from both rats and mice were able to correctly predict all tested compounds and to clearly distinguish immunosuppressants from control substances. Furthermore, animal studies can be refined by using MD cultures of PBMC. During a 28d benzo(a)pyrene treatment of rats we were able to follow the kinetic of an immune response by in vitro analyses. Addnl. evaluation of in vitro antibody responses of spleen cells and PBMC from rats treated with cyclophosphamide revealed similar results compared to the conventional ex vivo plaque forming cell assay (PFCA). In conclusion, investigation of in vitro antibody responses is a sensitive and reliable approach for detection of a compound induced specific effect on the immune system. MD cultures may not only replace the ex vivo TDAR in the future, but their implementation in routine toxicol. also enables refinement of existing in vivo studies by reducing the numbers of animals.

The construction of ZnIn2S4 based heterogeneous structure combined with in-situ relatively metal doping remains a great challenge. A direct Step-scheme (S-scheme) of in-situ Mo doped ZnIn2S4 wrapped MoO3 (MoO3@Mo-ZIS) was prepared in this work based on the thermal solubility properties of MoO3. The optimized photocatalyst of MoO3@Mo-ZIS exhibits superior H2 evolution rate of 5.5 mmol/g/h without co-catalysts, which is the 6.5 and 1.3 times of ZIS and 40 Mo doped ZIS (40 Mo-ZIS), resp. The excellent photocatalytic activity was attributed to the Mo doping and formation of Mo-S species. The d. functional theory (DFT) calculations demonstrate that the Mo-S species would form a new hybridized state near the Fermi level, reducing the ΔGH* to enhance photocatalytic hydrogen evolution reaction (HER). Furthermore, the direct S-scheme heterojunction of MoO3@Mo-ZIS confirmed by ESR (EPR) and Kelvin probe force microscopy (KPFM) promotes photogenerated carrier separation, thus enhancing the performance of photocatalytic HER.

A novel arylation of sulfonamides RSO2N(R1)C(O)R2 (R = 4-methylphenyl, naphthalen-2-yl, 2,3-dihydro-1-benzofuran-6-yl, etc.; R1 = Ph, Me, Bn, etc.; R2 = Ph, Me, Bn, n-pentyl, 4-cyanophenyl) with boronic acids R3B(OH)2 [R3 = 4-(methoxycarbonyl)phenyl, 4-methylnaphthalen-1-yl, 1-benzofuran-2-yl, etc.] to afford numerous diaryl sulfones RS(O)2R3 via a visible light-mediated N-S bond cleavage, rather than the typical transition-metal-catalyzed C(O)-N bond activation, is described. This methodol., which represents the first catalyst-free protocol for the sulfonylation of boronic acids, is characterized by its simple reaction conditions, good functional group tolerance and high efficiency. Several successful examples for the late-stage functionalization of diverse sulfonamides indicate the high potential utility of this method in pharmaceutical science and organic synthesis.

The chem. composition, crystalline structure and optical properties of un-doped ZnO (UZO) and indium (6%)-doped ZnO (IZO) thin films grown on Si substrate were studied using XPS, X-ray diffraction (XRD) and photoluminescence (PL) techniques. The results are complementary and confirm each other. The surface is cleaned using checked ultra-high vacuum (UHV) treatment (argon ion sputtering followed by successive heating). For IZO, the XPS anal. displays that the indium incorporates in the ZnO matrix to form the In-O-Zn-type chem. bonds. The PL of UZO reveals structural defects, including oxygen interstitial (Oi), oxygen vacancies (VO), zinc vacancies (VZn) and interstitial zinc (Zni), and they decrease with the In doping and UHV treatment. For IZO, the PL measurements show the great interest of UHV treatment to stimulate the incorporation of indium into the ZnO matrix. There is an increase in the UV emission intensity and improvement of its phys. structure. The In (6%) doping of ZnO is convenient to compensate the zinc vacancies (VZn), eliminate Zni and VO, and ensure the structural homogeneity of IZO film. All the detected peaks of the XRD patterns are matched to the wurtzite crystalline structure for both UZO and IZO thin films grown mainly along the (002) orientation plane.

Jung, Hyun-Joo; Chen, Zheng; McCarty, Nami published the artcile< Stem-like tumor cells confer drug resistant properties to mantle cell lymphoma>, Recommanded Product: 2-(Bis(2-chloroethyl)amino)-1,3,2-oxazaphosphinane 2-oxide hydrate, the main research area is chemotherapy resistance mantle cell lymphoma cytotoxic.

We recently identified clonogenic malignant stem cell populations in human mantle cell lymphoma (MCL), a particularly deadly subtype of non-Hodgkin lymphoma (NHL). We discovered that CD45++CD19– MCL cells, which we termed MCL-initiating cells (MCL-ICs), are highly tumorigenic and display self-renewal capacity in vivo; in contrast, CD45++CD19++ MCL cells, which constitute the vast majority of cells within the tumors, show no self-renewal capacity and greatly reduced tumorigenicity. Given the newly appreciated role of cancer-initiating cells in the drug resistance of cancers, it is critical to investigate whether CD45++CD19– MCL-ICs play a role in the drug resistance of human MCL. We discovered that MCL-ICs were more resistant to clin. relevant chemotherapeutic agents, in combination or in a single regimen, compared to CD45++CD19++ cells, and that this drug resistance was largely due to quiescent properties with enriched ABC transporters. In conclusion, designing novel therapies to kill CD45++CD19– MCL-ICs may prevent relapse and increase patient survival.
