Deo, Namita published the artcileBiodegradation of some organic reagents from mineral process effluents, HPLC of Formula: 2016-56-0, the publication is Process Metallurgy (1999), 687-696, database is CAplus.

Bacillus polymyxa were studied for the removal of organics such as dodecylamine, ether diamine, iso-Pr xanthate and Na oleate from wastewater. Time-bound removal of these organics from an alk. solution was studied under different exptl. conditions during bacterial growth and in the presence of metabolites by frequent monitoring of residual concentrations as a function of time, reagent concentration and cell d. The stages and mechanisms in the biodegradation process were monitored through UV-visible and FTIR spectroscopy. Surface chem. of the bacterial cells as well as the biosorption tendency for various organics were established through electrokinetic and adsorption d. measurements. Cationic amines were biosorbed followed by their degradation through bacterial metabolism The presence of the organics promoted bacterial growth through effective bacterial utilization of N and C from the organics Under optimal conditions, complete degradation and bioremoval of all the organics could be achieved.

Deo, Namita published the artcileBiodegradation of some organic flotation reagents by Bacillus polymyxa, Formula: C14H31NO2, the publication is Bioremediation Journal (1998), 2(3-4), 205-214, database is CAplus.

The soil bacterium, Bacillus polymyxa, is shown to effectively remove organic flotation collectors such as dodecyl amine, diamine, sodium iso-Pr xanthate, and sodium oleate from alk. solutions Adsorption and bacterial growth studies indicated enhanced surface affinity of the amine collectors toward the bacterial cells. All the organic reagents were efficiently removed from alk. solutions through bacterial interaction. UV-visible and Fourier transform IR spectra during biodegradation of these reagents revealed the stages in biodegradation Possible mechanisms are outlined.

Meegan, Mary J. published the artcilePiperlongumine (piplartine) and analogues: Antiproliferative microtubule-destabilising agents, Safety of (E)-3-(2,4-Dimethoxyphenyl)acrylic acid, the publication is European Journal of Medicinal Chemistry (2017), 453-463, database is CAplus and MEDLINE.

Piperlongumine (piplartine, 1) is a small mol. alkaloid that is receiving intense interest due to its antiproliferative and anticancer activities. We investigated the effects of 1 on tubulin and microtubules. Using both an isolated tubulin assay, and a combination of sedimentation and western blotting, we demonstrated that 1 is a tubulin-destabilizing agent. This result was confirmed by immunofluorescence and confocal microscopy, which showed that microtubules in MCF-7 breast cancer cells were depolymerized when treated with 1. We synthesized a number of analogs of 1 to explore structure-activity relationships. Compound 13 had the best cytotoxic profile of this series, showing potent effects in human breast carcinoma MCF-7 cells while being relatively non-toxic to non-tumorigenic MCF-10a cells. These compounds will be further developed as potential clin. candidates for the treatment of breast cancer.

Panne, Patricia published the artcileCyanide initiated perfluoroorganylations with perfluoroorgano silicon compounds, Name: Trimethyl(perfluorophenyl)silane, the publication is Journal of Fluorine Chemistry (2001), 112(2), 283-286, database is CAplus.

Cyanophenylphosphines, Ph₂PCN or PhP(CN)₂, do not react with Me₃SiCF₃ or Me₃SiC₆F₅ in the absence of cyanide ions. Catalytic amounts of ionic cyanides such as [NEt₄]CN, [18-crown-6-K]CN or NaCN initiate perfluoroorganylation reactions. The trifluoromethylphosphines, Ph₂PCF₃ and PhP(CF₃)₂, as well as the pentafluorophenylphosphines, Ph₂PC₆F₅ and PhP(C₆F₅)₂, are isolated in 60-75% yield. In DMF or acetone solutions, side reactions are observed while reactions in CH₂Cl₂ and MeCN proceed selectively. Me₃SiCF₃ addition to the carbonyl groups of DMF and acetone occurs on treatment of Me₃SiCF₃ solutions of these solvents with catalytic amounts of cyanide, cyanate or thiocyanate salts even at low temperature The formation of the reactive silicate [Me₃Si(CN)CF₃]^– in reactions with an excess of [18-crown-6-K]CN is proved by low temperature NMR studies.

Tyrra, Wieland published the artcileOn the attempted synthesis of salts with the trimethyl[bis(pentafluorophenyl)]silicate ion, [Me₃Si(C₆F₅)₂]^–-A polyphenyl problem, Application of Trimethyl(perfluorophenyl)silane, the publication is Journal of Fluorine Chemistry (2005), 126(9-10), 1303-1306, database is CAplus.

Reactions of Me₃SiC₆F₅ and MF (M = Cs, [NMe₄]) in molar ratios varying from 1:1 to 2:1 in a temperature range between -70 ¡ãC and ambient proceed more or less selectively to form 1-H-perfluoro-4,4′-polyphenyls, 1-H(C₆F₄)_nF, independent of the solvent used (DME, THF). The silicates expected, M[Me₃Si(C₆F₅)F] and M[Me₃Si(C₆F₅)₂], were not detected even in low temperature NMR experiments The polymeric material formed was identified after aqueous working up as a mixture of 1-H(C₆F₄)_nF (n = 4-13) by elemental analyses and EI mass spectrometric studies.

Hassoon, Salah published the artcileElectron Transfer Photoreduction of 5,7-Diiodo-3-butoxy-6-fluorone with Tetrabutylammonium Triphenylbutylborate and N,N-Dimethyl-2,6-diisopropylaniline, Computed Properties of 2909-77-5, the publication is Journal of Physical Chemistry (1995), 99(23), 9416-24, database is CAplus.

The photoreduction of 5,7-diiodo-3-butoxy-6-fluorone (DIBF) in the presence of the electron donors, tetrabutylammonium triphenylbutylborate (BORATE), and N,N-dimethyl-2,6-diisopropylaniline (DIDMA) was studied in acetonitrile solution The transient phenomena examined using nanosecond laser flash photolysis confirm that the reduction is a one-electron transfer process from the electron donor to the excited triplet state of the dye. Triplet quenching rate constants were measured for BORATE and DIDMA as well as oxygen. The relative quenching rates for oxygen and DIDMA are ¡Ö20:1. The electron transfer rates calculated are 6.7 ¡Á 10⁷ and 1.2 ¡Á 10⁸ s^-1 in the BORATE and DIDMA systems, resp. The dye radical anion (DIBF^?, ¦Ë_max ¡Ö 420 nm) formed by the electron transfer reaction is the only product obtained in the BORATE case. However, with DIDMA the dye “neutral” radical (DIBF^?, ¦Ë_max ¡Ö 360 nm) was detected as the only product. DIBF^? formed after protonation of DIBF^?- by proton transfer from the amino cation radical. This implies that the proton transfer is too fast to measure on the nanosecond time scale. This is the first such observation in these systems. Singlet oxygen formed by oxygen quenching of the dye triplet was found to be quenched by the electron donors via an electron transfer process also. No quenching of DIBF triplet occurred in the presence of the electron acceptor (4-octyloxyphenyl)phenyliodonium hexafluoroantimonate (OPPI). The principal photobleached products detected by HPLC were reduced quinomethines in the DIDMA case and the ammonium salts of the reduced quinomethines in the BORATE case. Reoxygenation of these products regenerates the original dye in a reaction the rate of which depends on the polarity of the solution However, the reoxygenation of the quinomethines is faster than that of their ammonium salts under the same conditions.
