In general, there are 2 options to overcome this problem: one is linkage of water-soluble groups to the BODIPY core [12] and the other is linkage of the BODIPY dyes to a water-soluble compound [13,14].. According to the literature, phosphazene compounds generally have good solubility in organic solvents. There are several examples of water-soluble phosphazenes in the literature, but to the best of our knowledge, most of them are.

We tried to solve this problem in the present work using some water-soluble polymers and tried several PVPs with different molecular weights as polymeric additives.. PVP is a water-soluble polymer made from the monomer N-vinylpyrrolidone. synthetic blood plasma substitute and in the cosmetic, drug, and food-processing industries. The dependences of current efficiency of chromium deposition versus PVP content in the bath are shown in Figure 2..

Abstract: In the present study, the antioxidant properties of peripherally and nonperipherally water-soluble tetra (quinoline 5-sulfonic acid) substituted metal-free (1, 2), Zn(II) (3, 4), Co(II) (5, 6), and Mn(III)Cl (7, 8) phthalocyanine (Pc) derivatives were reported.

The reducing activities of the different water-soluble polysaccharides were positively correlated with concen- trations. At the highest concentration (10 mg/mL), the % inhibitions ob- served of the PoP, PeP and TP samples were and respectively. Functional properties of extracted polysaccharides are exhibited in Fig. Water holding capacities of the PoP, PeP and TP samples (Fig. These results were less than what was reported for galactomannans (15.20 g water/g sample) (Sciarini et al., 2009).

To the best of our knowledge, even though there are some studies in the literature in which phthalocyanines are evaluated as carbonic anhydrase and α‐glucosidase enzyme inhibitors [19–22], carbonic anhydrase and paraoxonase inhibition activity of anionic water-soluble phthalocyanines has not been reported.

Among organic additives, special attention has been paid to water-soluble polymers, and their beneficial effects on the electrodeposition processes of various metals were recently established in a number of works. In this paper, we aim to understand, in particular, the effect of a water-soluble polymer on the iron deposition process from the electrolyte on the basis of Fe(III) salts..

Binding of water soluble cationic zinc (II) phthalocyanine complexes with BSA The binding properties of the samples (6–9) to BSA were studied by spectrofluorometry at room temperature. A PBS solution of water (fixed concentration) was titrated with varying concentrations of the respective samples (6–9) solutions in water.

Moreover, although there are many studies about the effects of vitamins on GR, such as the effects in vivo of folate deficiency on GR, GPX, and GST [16] and mice fed with niacin and nicotinamide [17], the effects of some soluble-water vitamins on GR in vitro were researched for the first time in this article.

There has been much interest devoted to the use of water-soluble catalysts, since water is nontoxic, nonflammable, and relatively inexpensive when compared to organic solvents. Furthermore, simplifying the separation of the water-soluble catalyst and inorganic salts, which occurred during the reaction, from the product enables simple purification.

As summarized above, the bulk of the recent wide-area radiologi- cal decontamination literature has focused on the removal of mobile water-soluble species. This leaves open the question of the best meth- ods to remediate insoluble particulate contamination. Many of the technologies for water soluble contaminants rely on physical re- moval, so, in principle, may also be applicable to physical removal of in- soluble particles.

Recently, a great deal of attention has been paid to the search for water-soluble metal complexes because, in principle, the advantages of homogeneous and heterogeneous catalysts can be combined. 7,8 This concept has been successfully extended to the NHC ligands by introducing polar functionalities such as -SO − 3 , -COO. 9 In this context, we have, very recently, reported the synthesis and catalytic activity of water-soluble complexes A and B obtained by cleavage of the dimer [(NHC)PdBr 2 ] 2 with

They have presented a spectroscopic investigation of the binding of the water-soluble quaternized ionic and zwitterionic gallium (III) and indium (III) Pc complexes to BSA. The synthesis of novel tetra aminopropylamid substituted phthalocyanines, which can stimulate new discussions about their biochemical role in the organism, is exhibited in this work.

Annatto may be water soluble or oil soluble.. Water soluble annatto contains bixin, a carotenoid and the main colourant which may be interconverted by hydrolysis to norbixin.. Water soluble annatto contains sodium or potassium salts of norbixin as the major colourant.. Oil- and Water-Soluble Annatto Extracts. Oil-soluble Annatto Extracts diluted with acetone exhibit absorbance maxima at 439, 470, and 501 nm.

Some of the neutral (that is non-ionic) ligands are water-soluble due to their ability of forming several strong hydrogen bonds to the surrounding water molecules. Most of the ligands in AOC, however, are derived from water- insoluble tertiary phosphines by attaching onto them ionic or polar groups,.

Finally, expansion of the IR family could be linked with prey detection as well as pheromone detection of water-soluble hydrophilic acids and amines, many of which are common chemosensory signals for aquatic species [84, 85].. Water striders can be exposed to various toxic com- pounds found in the water, including those generated by pesticides, insecticides, and from other human activities as well as those found in their prey.
