In the present study various substituted bisazo disperse dyes 2-(1′-substituted Ph azo)-4-(3′-nitrophenyl)-5-(2”,4”-dinitro Ph azo)thiazole derivatives have been synthesized using substituted 3°-amine, 2-amino-4-(3′-nitrophenyl)thiazole and 2,4-dinitroaniline. These were characterized using elemental anal., 1H NMR (NMR) and IR spectra. Their dyeing performance on polyester fiber was assessed and fastness properties of these dyes were evaluated by applying them to polyester fiber. These dyes exhibited moderate to good anti-bacterial and anti-fungal activities.

Majstrowicz, Katarzyna; Honnert, Ulrike; Nikolaus, Petra; Schwarz, Vera; Oeding, Stefanie J.; Hemkemeyer, Sandra A.; Baehler, Martin published the artcile< Coordination of mitochondrial and cellular dynamics by the actin-based motor Myo19>, Application of C22H23F2N3O2S, the main research area is actin motor myosin mitochondrial cellular dynamic coordination; Cell adhesion; Mitochondria; Mitosis; Myosin.

Myosin XIX (Myo19) is an actin-based motor that competes with adaptors of microtubule-based motors for binding to the outer mitochondrial transmembrane proteins Miro1 and Miro2 (collectively Miro, also known as RhoT1 and RhoT2, resp.). Here, we investigate which mitochondrial and cellular processes depend on the coordination of Myo19 and microtubule-based motor activities. To this end, we created Myo19-deficient HEK293T cells. Mitochondria in these cells were not properly fragmented at mitosis and were partitioned asym. to daughter cells. Respiratory functions of mitochondria were impaired and ROS generation was enhanced. On a cellular level, cell proliferation, cytokinesis and cell-matrix adhesion were neg. affected. On a mol. level, Myo19 regulates focal adhesions in interphase, and mitochondrial fusion and mitochondrially associated levels of fission protein Drp1 and adaptor proteins dynactin and TRAK1 at prometaphase. These alterations were due to a disturbed coordination of Myo19 and microtubulebased motor activities by Miro.

Huang, David S.; Wong, Henry L.; Georg, Gunda I. published the artcile< Synthesis and evaluation of C2 functionalized analogs of the α-tubulin-binding natural product pironetin>, Reference of 171877-39-7, the main research area is pironetin analog preparation anticancer structure activity ovarian cancer; Cytotoxicity; Pironetin; Structure-activity; Synthesis; Tubulin.

Pironetin is an α-tubulin-binding natural product with potent antiproliferative activity against several cancer cell lines that inhibits cell division by forming a covalent adduct with α-tubulin via a Michael addition into the natural product’s α,β-unsaturated lactone. We designed and prepared analogs carrying electron-withdrawing groups at the α-position (C2) of the α,β-unsaturated lactone with the goal to generate potent and selective binding analogs. We prepared derivatives I (R = F, Me, Cl, Br, Ph) containing halogens, a Ph, and a Me group at the C2 position to evaluate the structure-activity relationship at this position. Testing of the analogs in ovarian cancer cell lines demonstrated 100-1000-fold decreased antiproliferative activity.

Love, Anna C.; Prescher, Jennifer A. published the artcile< Seeing (and Using) the Light: Recent Developments in Bioluminescence Technology>, Quality Control of 2591-17-5, the main research area is review luciferase luciferin bioluminescence optical imaging; bioluminescence; imaging; luciferase; luciferin; optogenetics.

A review. Bioluminescence has long been used to image biol. processes in vivo. This technol. features luciferase enzymes and luciferin small mols. that produce visible light. Bioluminescent photons can be detected in tissues and live organisms, enabling sensitive and noninvasive readouts on physiol. function. Traditional applications have focused on tracking cells and gene expression patterns, but new probes are pushing the frontiers of what can be visualized. The past few years have also seen the merger of bioluminescence with optogenetic platforms. Luciferase-luciferin reactions can drive light-activatable proteins, ultimately triggering signal transduction and other downstream events. This review highlights these and other recent advances in bioluminescence technol., with an emphasis on tool development. We showcase how new luciferins and engineered luciferases are expanding the scope of optical imaging. We also highlight how bioluminescent systems are being leveraged not just for sensing-but also controlling-biol. processes.

The two best aromatic-functionalized cyclofructan chiral stationary phases, R-naphthylethyl-carbamate cyclofructan 6 (RN-CF6) and dimethylphenyl-carbamate cyclofructan 7 (DMP-CF7), were synthesized and evaluated by injecting various classes of chiral analytes. They provided enantioselectivity toward a broad range of compounds, including chiral acids, amines, metal complexes, and neutral compounds It is interesting that they exhibited complementary selectivities and the combination of two columns provided enantiomeric separations for 43% of the test analytes. These extensive chromatog. results provided useful information about method development of specific analytes, and also gave some insight as to the enantioseparation mechanism.

With the aim to discover orally active small mols. that stimulate glucose uptake, high throughput screening of a library of 5000 drug-like compounds was conducted in differentiated skeletal muscle cells in presence of insulin. N-Substituted phthalazinone acetamide was identified as a potential glucose uptake modulator. Several novel derivatives were synthesized to establish structure activity relationships. Identified lead thiazolyl-phthalazinone acetamide (7114863; I) increased glucose uptake (EC50 of 0.07±0.02 μM) in differentiated skeletal muscle cells in presence of insulin. Furthermore, I was superior to rosiglitazone under similar exptl. conditions without inducing PPAR-γ agonist activity thus making it a very interesting scaffold.

Thakur, Nimisha; Patil, Rahul A.; Talebi, Mohsen; Readel, Elizabeth R.; Armstrong, Daniel W. published the artcile< Enantiomeric impurities in chiral catalysts, auxiliaries, and synthons used in enantioselective syntheses. Part 5>, Name: (S)-4-Benzylthiazolidine-2-thione, the main research area is chiral catalyst synthon enantioselective enantiomeric impurity; chiral separation; enantiomeric excess; enantiomeric impurity; enantioselective syntheses.

The enantiomeric excess of chiral starting materials is one of the important factors determining the enantiopurity of products in asym. synthesis. Fifty-one com. available chiral reagents used as building blocks, catalysts, and auxiliaries in various enantioselective syntheses were assayed for their enantiomeric purity. The test results were classified within five impurities level (ie, <0.01%, 0.01%-0.1%, 0.1%-1%, 1%-10%, >10%). Previously from 1998 to 2013, several reports have been published on the enantiomeric composition of more than 300 chiral reagents. This series of papers is necessitated by the fact that new reagents are forthcoming and that the enantiomeric purity of the same reagent can vary from batch to batch and/or from supplier to supplier. This report presents chiral liquid chromatog. (LC) and gas composition(GC) methods to sep. enantiomers of chiral compounds and evaluate their enantiomeric purities. The accurate and efficient LC anal. was done using newly introduced superficially porous particle (SPP 2.7μm) based chiral stationary phases (TeicoShell, VancoShell, LarihcShell-P, and NicoShell).

Schramm, Stefan; Al-Handawi, Marieh B.; Karothu, Durga Prasad; Kurlevskaya, Anastasiya; Commins, Patrick; Mitani, Yasuo; Wu, Chun; Ohmiya, Yoshihiro; Naumov, Pance published the artcile< Mechanically Assisted Bioluminescence with Natural Luciferase>, Computed Properties of 2591-17-5, the main research area is mechanic bioluminescence luciferase; Cypridina; bioluminescence; luciferase; mechanochemistry; solvent-assisted reactions.

Mechanochem. analogs have recently been established for several enzymic reactions, but they require periodic interruption of the reaction for sampling, dissolution, and (bio)chem. anal. to monitor their progress. By applying a mechanochem. procedure to induce bioluminescence analogous to that used by the marine ostracod Cypridina (Vargula) hilgendorfii, the light emitted by a bioluminescent reaction can be used to directly monitor the progress of a mechanoenzymic reaction without sampling. Mech. treatment of Cypridina luciferase with luciferin generates bright blue light which can be readily detected and analyzed spectroscopically. This mech. assisted bioluminescence proceeds through a mechanism identical to that of bioluminescence in solution, but has higher activation energy due to being diffusion-controlled in the viscous matrix. The results suggest that luciferases could be used as light-emissive reporters of mechanoenzymic reactions.
