Dendrimers are interesting candidates for various applications because of the high level of control over their architecture, the presence of internal cavities, and the possibility for multivalent interactions. More specifically, zwitterionic dendrimers modified with an equal number of oppositely charged groups have found use in in vivo biomedical applications. However, the design and control over the synthesis of these dendrimers remains challenging, in particular with respect to achieving full modification of the dendrimer. In this work, we show the design and subsequent synthesis of dendrimers that are highly charged while having zero net charge, that is zwitterionic dendrimers that are potential candidates for biomedical applications. First, we designed and fully optimized the synthesis of charge-neutral carboxybetaine and sulfobetaine zwitterionic dendrimers. Following their synthesis, the various zwitterionic dendrimers were extensively characterized. In this study, we also report for the first time the use of XPS as an easy-to-use and quant. tool for the compositional anal. of this type of macromols. that can complement techniques such as NMR and gel permeation chromatog. Finally, we designed and synthesized zwitterionic dendrimers that contain a variable number of alkyne and azide groups that allow straightforward (bio)functionalization via click chem.

Garcia Suarez, Eduardo J. published the artcileNew alkyl derivatives phosphine sulfonate (P-O) ligands. Catalytic activity in Pd-catalysed Suzuki-Miyaura reactions in water, Name: Sodium 3-bromopropane-1-sulfonate, the publication is Dalton Transactions (2007), 2859-2861, database is CAplus and MEDLINE.

Novel phosphine-alkanesulfonate P-O-chelate ligands and their palladium complexes were prepared; the complexes exhibit excellent catalytic activity in Suzuki-Miyaura coupling of aryl bromides and moderate activity in coupling of aryl chlorides with arylboronic acids. Reaction of (2-MeOC₆H₄)₂PLi with Br(CH₂)_nSO₃Na gave bidentate phosphinosulfonates (2-MeOC₆H₄)₂P(CH₂)_nSO₃H (1, 2; n = 2, 3). Complexation of 1 with [Pd₂(μ-Cl)₂(η¹,η²-C₈H₁₃OMe)₂] gave the palladium(II) complex, [Pd(η¹,η²-C₈H₁₃OMe)[(2-MeOC₆H₄)₂P(CH₂)_nSO₃-κO,κP]] (1a, C₈H₁₃OMe = 6-methoxy-1-cycloocten-5-yl), which structure was confirmed by x-ray diffraction anal. Suzuki-Miyaura coupling of R¹Br with R²B(OH)₂ catalyzed by Pd(OAc)₂/L (L = 1, 2) gave the corresponding biaryls R¹R² (R¹ = 4MeCOC₆H₄, Ph, 4-MeOC₆H₄; R² = Ph, 1-naphthyl, 4-FC₆H₄, 4-MeOC₆H₄) with >99% yields. The ligands 1 and 2 are air-stable as well as water soluble; the coupling reactions were run in neat water and under microwave heating as well.

Ellermann, Joachim published the artcileMethyl-coenzyme-M reductase from Methanobacterium thermoautotrophicum (strain Marburg). Purity, activity and novel inhibitors, Category: bromides-buliding-blocks, the publication is European Journal of Biochemistry (1989), 184(1), 63-8, database is CAplus and MEDLINE.

Methyl-coenzyme-M reductase from M. thermoautotrophicum (strain Marburg) was purified to a stage where, besides the α, β and γ subunits, no addnl. polypeptides were detectable in the preparation Under appropriate conditions the enzyme was found to catalyze the reduction of methyl-CoM with 7-mercaptoheptanoylthreonine phosphate (H-S-HTP) to CH₄ at a specific rate of 2.5 μmol min^-1 mg protein^-1. This finding contradicts a recent report that methyl-CoM reductase is only active when some contaminating proteins are present. The 2 polypeptides encoded by the open reading frames ORF₁ and ORF₂ of the methyl-CoM reductase transcription unit did not copurify with the α, β and γ subunits. They were neither required nor did they stimulate the activity under the assay conditions. 3-Bromopropanesulfonate (apparent K_i = 0.05 μM) and 2-azidoethanesulfonate (apparent K_i = 1 μM) were found to be 2 new competitive inhibitors of methyl-CoM reductase. Both inhibitors were considerably more effective than the classical 2-bromoethanesulfonate (apparent K_i = 4 μM).

Gunsalus, Robert P. published the artcilePreparation of coenzyme M analogs and their activity in the methyl coenzyme M reductase system of Methanobacterium thermoautotrophicum, Category: bromides-buliding-blocks, the publication is Biochemistry (1978), 17(12), 2374-7, database is CAplus and MEDLINE.

A number of 2-(methylthio)ethanesulfonate (Me-coenzyme M, I) analogs were synthesized and investigated as substrates for I reductase, an enzyme system found in extracts of M. thermoautotrophicum. Replacement of the Me moiety by an Et group yielded an analog which served as a precursor for C₂H₆ formation. Pr-coenzyme M, however, was not converted to C₃H₈. Analogs which contained addnl. methylene C atoms, such as 3-(methylthio)propanesulfonate or 4-(methylthio)butanesulfonate or analogs modified at the sulfide or sulfonate position, N-methyltaurine and 2-(methylthio)ethanol, were inactive. These analogs, in addition to a number of com. available compounds, also were tested for their ability to inhibit the reduction of I to CH₄. Bromoethanesulfonate and chloroethanesulonate proved to be potent inhibitors of the reductase, resulting in 50% inhibition at 7.9 × 10^-6 M and 7.5 × 10^-5 M, resp. Analogs of coenzyme M which contained modifications to other regions were also evaluated and found to be weak inhibitors of CH₄ biosynthesis.

Rao, Suma published the artcileHigh resolution protein separations using affinity ultrafiltration with small charged ligands, Safety of Sodium 3-bromopropane-1-sulfonate, the publication is Journal of Membrane Science (2006), 280(1+2), 781-789, database is CAplus.

Although the feasibility of affinity ultrafiltration was demonstrated more than 20 years ago, com. applications have not developed due to the high cost and practical limitations of the large macroligands needed for highly selective separations The objective of this study was to examine the use of small charged affinity ligands for protein purification by exploiting electrostatic interactions between the charged complex and an elec.-charged membrane. Experiments were performed using bovine serum albumin and ovalbumin with Cibacron Blue as the affinity ligand. Neg. charged versions of a composite regenerated cellulose membrane were generated by covalent attachment of a sulfonic acid functionality. Binding experiments were used to identify appropriate conditions for protein separations The selectivity for the separation of BSA and ovalbumin was a function of the solution conditions, Cibacron Blue concentration, and membrane charge, with the addition of Cibacron Blue causing a 30-fold increase in selectivity. A diafiltration process was performed at the optimal conditions, giving a BSA product with a purification factor of more than 90-fold and a yield greater than 90%. These results clearly demonstrate the potential of using a small charged affinity ligand for high resolution protein separations

Shao, Jiahui published the artcileHumic acid rejection and flux decline with negatively charged membranes of different spacer arm lengths and charge groups, Formula: C3H6BrNaO3S, the publication is Journal of Membrane Science (2013), 38-45, database is CAplus.

A series of novel charged ultrafiltration membranes that differed in spacer arm length and charge group were generated by covalent attachment of neg. charged group to a com. available regenerated cellulose membrane. Rejection of humic acid and flux decline were compared with essentially neutral and neg. charged versions of regenerated cellulose membranes of different spacer arm lengths and charge groups. Effects of membrane mol. weight cut-off and solution pH on humic acid removal and flux decline on neutral and neg. charged membranes of different spacer arm lengths were also compared. The membrane with larger spacer arm length has better rejection of humic acid and less membrane fouling compared to that with smaller spacer arm length. The modified neg. charged membrane with a strongly acidic (sulfonic acid) functional group has better rejection of humic acid and less membrane fouling than that with a weakly acidic (carboxylic acid) functional group. These exptl. results are consistent with the larger charge of the membranes having larger spacer arm length and sulfonic acid group. This study confirms that the appropriate design of membrane charge functionality could be an effective way for better removal of humic acid and reduction of membrane fouling due to the electrostatic interactions with the combination effect of membrane pore size.

Natrajan, Anand published the artcileA green synthesis of chemiluminescent N-sulfopropyl acridinium esters in ionic liquids without using the carcinogen 1,3-propane sultone, Formula: C3H6BrNaO3S, the publication is Green Chemistry Letters and Reviews (2013), 6(3), 237-248, database is CAplus.

Chemiluminescent acridinium dimethylphenyl esters containing hydrophilic N-sulfopropyl groups in the acridinium ring are used as labels in automated immunoassays for clin. diagnostics. Introduction of the N-sulfopropyl group in these labels is normally accomplished by N-alkylation of the corresponding, nonchemiluminescent acridine ester precursors with the toxic carcinogen 1,3-propane sultone. In the current study, we report that sodium 3-bromopropane sulfonate in ionic liquids (ILs) is a benign alternative to 1,3-propane sultone for introducing the N-sulfopropyl group in chemiluminescent acridinium ester labels. The sultone reagent can be eliminated in the synthesis of N-sulfopropyl acridinium dimethylphenyl ester labels by taking advantage of the increased reactivity of acridan esters toward nontoxic sodium 3-bromopropane sulfonate in [BMIM][BF₄]. Sodium 3-bromopropane sulfonate in ILs is also potentially a nontoxic alternative to 1,3-propane sultone for introducing the water-soluble, three-carbon sulfobetaine moiety in other mols. as well.
