4-[(2,4-Dihydroxy-benzyl-idene)ammonio]benzene-sulfonate trihydrate.

Project description:The title Schiff base compound, C(13)H(11)NO(5)S·3H(2)O, formed from sulfanilic acid and 2,4-dihydroxy-benzaldehyde, crystallized out as a zwitterion with the N atom protonated. The asymmetric unit consists of one 4-[(2,4-dihydroxy-benzyl-idene)ammonio]benzene-sulfonate and three water mol-ecules. The zwitterion exists in an E configuration with respect to the central C=N double bond. The two benzene rings of the mol-ecule are oriented at a dihedral angle of 27.33?(8)°. An intra-molecular N-H?O hydrogen bond stabilizes the mol-ecular structure. In the crystal, the zwitterions are linked into chains along [101] by inter-molecular O-H?O and N-H?O hydrogen bonds. The three water mol-ecules link these chains into a three-dimensional framework by additional inter-molecular O-H?O hydrogen bonds. A ??? inter-action [3.5485?(9)?Å] further stabilizes the crystal structure.

Sodium (1R)-d-glucit-1-yl-sulfonate monohydrate.

Project description:The title salt, Na(+)·C(6)H(13)O(9)S(-)·H(2)O, crystallizes with three independent cations, molecular anions and solvent water molecules in the asymmetric unit. This crystalline monohydrate addition product, formed by reaction of d-glucose and sodium hydrogen sulfite in water, forms a three-dimensional network through complex cation coordination and extensive inter-molecular hydrogen bonding. Each of the independent mol-ecules has an open-chain structure with the carbon chains adopting a sickle-like conformation, similar to that found in the potassium salt [Cole et al. (2001 ?). Carbohydr. Res.335, 1-10], but there are significant differences in the patterns of complexation.

Interaction behavior of polyion-counterion for sodium polystyrene sulfonate.

Project description:The specific conductances are measured for sodium polystyrene sulfonate in water and methanol-water mixture. The equivalent conductivity data against concentration are evaluated by scaling concept. The effects of the solvent composition and the polyelectrolyte concentration on the fractions of uncondensed counterions (f) , the polyion conductivities λp , the standard state free energies of counterion association ΔGAo , and the polyion transference number TP are calculated. The charge density (ξ) of sodium polystyrene sulfonate was used for the research article [1] to see the variation of the critical aggregation concentration of cetyltrimethyl ammonium bromide in sodium polystyrene sulfonate against the charge density of sodium polystyrene sulfonate.

Sodium tanshinone IIA sulfonate stimulated Cl- secretion in mouse trachea.

Project description:Sodium tanshinone IIA sulfonate (STS) is a derivate of tanshinone IIA, a lipophilic compound in Salvia miltiorrhiza. This study aimed to investigate the effect of STS on ion transport in mouse tracheal epithelium and the mechanisms underlying it. Short-circuit current (Isc) was measured to evaluate the effect of STS on transepithelial ion transport. Intracellular Ca2+ imaging was performed to observe intracellular Ca2+ concentration ([Ca2+]i) changes induced by STS in primary cultured mouse tracheal epithelial cells. Results showed that the apical application of STS at mouse trachea elicited an increase of Isc, which was abrogated by atropine, an antagonist of muscarinic acetylcholine receptor (mAChR). By removing ambient Cl- or applying blockers of Ca2+-activated Cl- channel (CaCC), the response of STS-induced Isc was suppressed. Moreover, STS elevated the [Ca2+]i in mouse tracheal epithelial cells. As a result, STS stimulated Cl- secretion in mouse tracheal epithelium via CaCC in an mAChR-dependent way. Due to the critical role of Cl- secretion in airway hydration, our findings suggested that STS may be used to ameliorate the airway dehydration symptom in cystic fibrosis (CF) and chronic obstructive pulmonary disease (COPD).

Crystal structure of sodium (1S)-d-lyxit-1-yl-sulfonate.

Project description:The title compound, Na(+)·C5H11O8S(-) [systematic name: sodium (1S,2S,3S,4R)-1,2,3,4,5-penta-hydroxy-pentane-1-sulfonate], is formed by reaction of d-lyxose with sodium bis-ulfite (sodium hydrogen sulfite) in water. The anion has an open-chain structure in which one of the oxygen atoms of the sulfonate residue, the S atom, the C atoms of the sugar chain and the O atom of the hy-droxy-methyl group form an essentially planar zigzag chain with the corresponding torsion angles lying between 179.80?(11) and 167.74?(14)°. A three-dimensional bonding network exists in the crystal structure involving hexa-coordination of sodium ions by O atoms, three of which are provided by a single d-lyxose-sulfonate unit and the other three by two sulfonate groups and one hy-droxy-methyl group, each from separate units of the adduct. Extensive inter-molecular O-H?O hydrogen bonding supplements this bonding network.

Mesna (2-mercaptoethane sodium sulfonate) functions as a regulator of myeloperoxidase.

Project description:Myeloperoxidase (MPO), an abundant protein in neutrophils, monocytes, and macrophages, is thought to play a critical role in the pathogenesis of various disorders ranging from cardiovascular diseases to cancer. We show that mesna (2-mercaptoethanesulfonic acid sodium salt), a detoxifying agent, which inhibits side effects of oxazaphosphorine chemotherapy, functions as a potent inhibitor of MPO; modulating its catalytic activity and function. Using rapid kinetic methods, we examined the interactions of mesna with MPO compounds I and II and ferric forms in the presence and absence of chloride (Cl-), the preferred substrate of MPO. Our results suggest that low mesna concentrations dramatically influenced the build-up, duration, and decay of steady-state levels of Compound I and Compound II, which is the rate-limiting intermediate in the classic peroxidase cycle. Whereas, higher mesna concentrations facilitate the porphyrin-to-adjacent amino acid electron transfer allowing the formation of an unstable transient intermediate, Compound I*, that displays a characteristic spectrum similar to Compound I. In the absence of plasma level of chloride, mesna not only accelerated the formation and decay of Compound II but also reduced its stability in a dose depend manner. Mesna competes with Cl-, inhibiting MPO's chlorinating activity with an IC50 of 5µM, and switches the reaction from a 2e- to a 1e- pathway allowing the enzyme to function only with catalase-like activity. A kinetic model which shows the dual regulation through which mesna interacts with MPO and regulates its downstream inflammatory pathways is presented further validating the repurposing of mesna as an anti-inflammatory drug.

Quercetin solubilisation in bile salts: A comparison with sodium dodecyl sulphate.

Project description:To understand the bioaccessibility of the flavonoid quercetin we studied its interaction with bile salt micelles. The environmental sensitivity of quercetin's UV-visible absorption spectrum gave information about quercetin partitioning. Two quercetin absorption peaks gave complementary information: Peak A (240-280nm) on the intermicellar phase and Peak B (340-440nm) on the micellar phase. Thus, by altering pH, we showed that only non-ionised quercetin partitions into micelles. We validated our interpretation by studying quercetin's interaction with SDS micelles. Pyrene fluorescence and the quercetin UV-visible spectra show that the adsorption site for pyrene and quercetin in bile salt micelles is more hydrophobic than that for SDS micelles. Also, both quercetin and pyrene reported a higher critical micelle concentration for bile salts than for SDS. Our method of using a flavonoid as an intrinsic probe, is generally applicable to other lipophilic bioactives, whenever they have observable environmental dependent properties.

Experimental Investigation on Mechanism of Latent Heat Reduction of Sodium Acetate Trihydrate Phase Change Materials.

Project description:Sodium acetate trihydrate (SAT) phase change material (PCM) has been well known for thermal energy storage due to its high latent heat and resource abundance. However, SAT suffers from severe latent heat reduction after heating and cooling cycles. Although a few of previous researches showed the reduction could be effectively inhibited by using thickeners, the mechanisms of the reduction process and thickeners' inhibition have not been deeply explored till now. In this work, SAT modified by 5 wt.% nucleating agent of disodium hydrogen phosphate dodecahydrate (SAT/5 wt.% DSP) was prepared and 200 thermal cycles were carried out. The differential scanning calorimeter, Rheometer, X-ray diffractometry, and scanning electron microscope were used to investigate the extent of latent heat reduction, viscosity, phase composition and microstructure, respectively, and the infrared thermal imaging method was used to evaluate heat storage capacity. It was found that the latent heat of SAT/5 wt.% DSP dropped dramatically and the relative decrease in latent heat was measured to be 22.44%. The lower layer of SAT/5 wt.% DSP contained 24.1 wt.% CH3COONa, which was quantitatively consistent with the reduction extent. Furthermore, the phase change endothermic time of the lower layer was only 44.1% of that of the upper. SAT/5 wt.% DSP was further modified by 3 wt.% thickener of carboxymethyl cellulose (SAT/5 wt.% DSP/3 wt.% CMC) and endured 200 thermal cycles. The extent of the latent heat reduction of SAT/5 wt.% DSP/3 wt.% CMC was only 9.29%, and phase compositions were more homogeneous. The 3 wt.% CMC increased viscosity by 14 times, which effectively prevented the Stokes sedimentation velocity of CH3COONa in melts and inhibited the final macroscopic phase separation.
