Hayashi, Kumiko; Miyamoto, Miki G.; Niwa, Shinsuke published the artcile< Effects of dynein inhibitor on the number of motor proteins transporting synaptic cargos>, Application In Synthesis of 2222768-84-3, the main research area is dynein inhibitor motor protein synaptic cargo.

Synaptic cargo transport by kinesin and dynein in hippocampal neurons was investigated by noninvasively measuring the transport force based on nonequilibrium statistical mechanics. Although direct phys. measurements such as force measurement using optical tweezers are difficult in an intracellular environment, the noninvasive estimations enabled enumerating force-producing units (FPUs) carrying a cargo comprising the motor proteins generating force. The number of FPUs served as a barometer for stable and long-distance transport by multiple motors, which was then used to quantify the extent of damage to axonal transport by dynarrestin, a dynein inhibitor. We found that dynarrestin decreased the FPU for retrograde transport more than for anterograde transport. This result indicates the applicability of the noninvasive force measurements. In the future, these measurements may be used to quantify damage to axonal transport resulting from neuronal diseases, including Alzheimer’s, Parkinson’s, and Huntington’s diseases.

Sun, Hua; Mu, Zifeng; Yang, Canglei; Zhang, Kai; Ji, Xingyu; Zhang, Tianshu; Ding, Huanda; Wang, Shifan; Dong, Liming; Zhang, Jing; Zhang, Qichun published the artcile< Facile Azabenz-Annulations through UV-induced Photocyclization: A Promising Method for Perylenediimide-Based Organic Semiconductors>, Quality Control of 1003-32-3, the main research area is bis azabenz annulated perylenediimide preparation optical electrochem semiconducting property; azabenz-annulations; perylenediimides; photocyclization; semiconductors; ultraviolet-induced.

Herein, four bis-azabenz-annulated PDIs (bis-AzaBPDIs) I (Ar = Ph, thiophen-2-yl, 2-cyanothiophen-5-yl, thiazol-5-yl) are concisely synthesized in high yields through UV-induced photocyclization, where the reaction processes including aldimine condensation, cyclization, and oxidative re-aromatization are investigated. The optical characterizations and theor. simulation reveal that the unique properties of the four bis-AzaBPDIs are comparable to their parent PDI. Organic field effect transistors with compounds I (Ar = thiophen-2-yl, 2-cyanothiophen-5-yl, thiazol-5-yl) as active layers indicated that all compounds showed unipolar electron transport properties with the mobilities of 1.1×10-3, 5.8×10-4, and 8.5×10-6 cm2 V-1 s-1, resp. These results suggest the great potential of bis-AzaBPDIs as organic semiconductors. The easy preparation approach reported in this work would renew research interest in developing bis-AzaBPDI-based optoelectronic mols.

Takakura, Hideo published the artcile< Molecular design of D-luciferin-based bioluminescence and 1,2-dioxetane-based chemiluminescence substrates for altered output wavelength and detecting various molecules>, Recommanded Product: (S)-2-(6-Hydroxybenzo[d]thiazol-2-yl)-4,5-dihydrothiazole-4-carboxylic acid, the main research area is review luciferin bioluminescence chemiluminescence substrate imaging reagent mol design; bioluminescence; chemiluminescence; design strategy; imaging; molecular probes; near infrared.

A review. Optical imaging including fluorescence and luminescence is the most popular method for the in vivo imaging in mice. Luminescence imaging is considered to be superior to fluorescence imaging due to the lack of both autofluorescence and the scattering of excitation light. To date, various luciferin analogs and bioluminescence probes have been developed for deep tissue and mol. imaging. Recently, chemiluminescence probes have been developed based on a 1,2- dioxetane scaffold. In this , the accumulated findings of numerous studies and the design strategies of bioluminescence and chemiluminescence imaging reagents are summarized.

Kadota, Ayano; Moriguchi, Misato; Watanabe, Tadashi; Sekine, Yuichi; Nakamura, Shigeo; Yasuno, Takumi; Ohe, Tomoyuki; Mashino, Tadahiko; Fujimuro, Masahiro published the artcile< A pyridinium-type fullerene derivative suppresses primary effusion lymphoma cell viability via the downregulation of the Wnt signaling pathway through the destabilization of β-catenin>, Product Details of C11H8N2O3S2, the main research area is Wnt beta catenin pyridinium fullerene suppression primary effusion lymphoma; Kaposi’s sarcoma‑associated herpesvirus; Wnt signaling; fullerene; primary effusion lymphoma; pyridinium fullerene; β‑catenin.

Primary effusion lymphoma (PEL) is defined as a rare subtype of non-Hodgkin′s B cell lymphoma, which is caused by Kaposi′s sarcoma-associated herpesvirus (KSHV) in immunosuppressed patients. PEL is an aggressive type of lymphoma and is frequently resistant to conventional chemo- therapeutics. Therefore, the discovery of novel drug candidates for the treatment of PEL is of utmost importance. In order to discover potential novel anti-tumor compounds against PEL, the authors previously developed a pyrrolidinium-type fullerene derivative, 1,1,1′,1′-tetramethyl [60]fullerenodi- pyrrolidinium diiodide (derivative #1), which induced the apoptosis of PEL cells via caspase-9 activation. In the present study, the growth inhibitory effects of pyrrolidinium-type (derivatives #1 and #2), pyridinium-type (derivatives #3 and #5 to #9) and anilinium-type fullerene derivatives (derivative #4) against PEL cells were evaluated. This anal. revealed a pyridinium-type derivative (derivative #5; 3-5′-(ethoxycarbonyl)-1′,5′-dihydro-2′H-[5,6]fullereno-C60-Ih-[1,9-c] pyrrol-2′-yl-1-methylpyridinium iodide), which exhibited antitumor activity against PEL cells via the downregulation of Wnt/β-catenin signaling. Derivative #5 suppressed the viability of KSHV-infected PEL cells compared with KSHV-uninfected B-lymphoma cells. Furthermore, derivative #5 induced the destabilization of β-catenin and suppressed β-catenin-TCF4 transcriptional activity in PEL cells. It is known that the constitutive activation of Wnt/β-catenin signaling is essential for the growth of KSHV-infected cells. The Wnt/β-catenin activation in KSHV-infected cells is mediated by KSHV latency-associated nuclear antigen (LANA). The data demonstrated that derivative #5 increased β-catenin phosphorylation, which resulted in β-catenin polyubiquitination and subsequent degradation Thus, derivative #5 overcame LANA-mediated β-catenin stabilization. Furthermore, the administration of derivative #5 suppressed the development of PEL cells in the ascites of SCID mice with tumor xenografts derived from PEL cells. On the whole, these findings provide evidence that the pyridinium-type fullerene derivative #5 exhibits antitumor activity against PEL cells in vitro and in vivo. Thus, derivative #5 may be utilized as a novel therapeutic agent for the treatment of PEL.

A binding ensemble profiling with (f)photoaffinity labeling (BEProFL) approach that utilizes photolabeling of HDAC8 with a probe containing a UV-activated aromatic azide, mapping of the covalent modifications by liquid chromatog.-tandem mass spectrometry, and a computational method to characterize the multiple binding poses of the probe is described. By use of the BEProFL approach, two distinct binding poses of the HDAC8 probe were identified. The data also suggest that an “”upside-down”” pose with the surface binding group of the probe bound in an alternative pocket near the catalytic site may contribute to the binding.

Choi, Sunju; Matta, Hittu; Gopalakrishnan, Ramakrishnan; Natarajan, Venkatesh; Gong, Songjie; Jeronimo, Alberto; Kuo, Wei-Ying; Bravo, Bryant; Chaudhary, Preet M. published the artcile< A novel thermostable beetle luciferase based cytotoxicity assay>, SDS of cas: 2591-17-5, the main research area is luciferase thermostability isolation beetle anticancer agent cytotoxicity.

Cytotoxicity assays are essential for the testing and development of novel immunotherapies for the treatment of cancer. We recently described a novel cytotoxicity assay, termed the Matador assay, which was based on marine luciferases and their engineered derivatives In this study, we describe the development of a new cytotoxicity assay termed ‘Matador-Glo assay’ which takes advantage of a thermostable variant of Click Beetle Luciferase (Luc146-1H2). Matador-Glo assay utilizes Luc146-1H2 and D-luciferin as the luciferase-substrate pair for luminescence detection. The assay involves ectopic over-expression of Luc146-1H2 in the cytosol of target cells of interest. Upon damage to the membrane integrity, the Luc146-1H2 is either released from the dead and dying cells or its activity is preferentially measured in dead and dying cells. We demonstrate that this assay is simple, fast, specific, sensitive, cost-efficient, and not labor-intensive. We further demonstrate that the Matador-Glo assay can be combined with the marine luciferase-based Matador assay to develop a dual luciferase assay for cell death detection. Finally, we demonstrate that the Luc146-1H2 expressing target cells can also be used for in vivo bioluminescence imaging applications.

Zielonka, Jacek; Podsiadly, Radoslaw; Zielonka, Monika; Hardy, Micael; Kalyanaraman, Balaraman published the artcile< On the use of peroxy-caged luciferin (PCL-1) probe for bioluminescent detection of inflammatory oxidants in vitro and in vivo - Identification of reaction intermediates and oxidant-specific minor products>, HPLC of Formula: 115144-35-9, the main research area is inflammatory oxidant bioluminescence probe peroxy caged luciferin; Bioluminescence; Boronate probes; Luciferin; Spin traps.

Peroxy-caged luciferin (PCL-1)(I) probe was first used to image hydrogen peroxide in living systems (Van de Bittner et al., 2010 [9]). Recently this probe was shown to react with peroxynitrite more potently than with hydrogen peroxide (Sieracki et al., 2013 [11]) and was suggested to be a more suitable probe for detecting peroxynitrite under in vivo conditions. In this work, we investigated in detail the products formed from the reaction between PCL-1 and hydrogen peroxide, hypochlorite, and peroxynitrite. HPLC anal. showed that hydrogen peroxide reacts slowly with PCL-1, forming luciferin as the only product. Hypochlorite reaction with PCL-1 yielded significantly less luciferin, as hypochlorite oxidized luciferin to form a chlorinated luciferin. Reaction between PCL-1 and peroxynitrite consists of a major and minor pathway. The major pathway results in luciferin and the minor pathway produces a radical-mediated nitrated luciferin. Radical intermediate was characterized by spin trapping. We conclude that monitoring of chlorinated and nitrated products in addition to bioluminescence in vivo will help identify the nature of oxidant responsible for bioluminescence derived from PCL-1.
