General description

Sodium tetraborate decahydrate is a naturally occurring material used as a catalyst or additive for many organic transformations such as Nef reaction, Knoevenagel condensation, substitution, addition, selective methylation of vicinal diols, and desilylation of trimethylsilyl alkynones.

Application

Sodium tetraborate decahydrate can be used as a catalyst in the:

Regioselective thiolysis of 1,2-epoxides by using thiols to synthesize β-hydroxy sulfides.
Hetero-Michael addition of thiols with electron-deficient olefins to synthesize corresponding β-adducts.
Solvent-free Biginelli reaction to synthesize 3,4-dihydropyrimidin-2(1H)-ones.

It can also be used as an additive to prepare polypyrrole-borax composites with high dielectric properties.

Observing protein interaction dynamics to chemically defined chromatin fibers by colocalization single-molecule fluorescence microscopy.

Maxime Mivelaz et al.

Methods (San Diego, Calif.), 184, 112-124 (2020-02-01)

In eukaryotic cells, the genome is packaged into chromatin and exists in different states, ranging from open euchromatic regions to highly condensed heterochromatic regions. Chromatin states are highly dynamic and are organized by an interplay of histone post-translational modifications and

N-terminal syndecan-2 domain selectively enhances 6-O heparan sulfate chains sulfation and promotes VEGFA165-dependent neovascularization.

Federico Corti et al.

Nature communications, 10(1), 1562-1562 (2019-04-07)

The proteoglycan Syndecan-2 (Sdc2) has been implicated in regulation of cytoskeleton organization, integrin signaling and developmental angiogenesis in zebrafish. Here we report that mice with global and inducible endothelial-specific deletion of Sdc2 display marked angiogenic and arteriogenic defects and impaired

Effects of boric acid and borax on titanium dioxide genotoxicity.

Journal of applied toxicology : JAT, 28(5), 658-664 (2007-11-21)

Titanium dioxide (TiO(2)) is a potential carcinogenic/mutagenic agent although it is used in many areas including medical industries and cosmetics. Boron (as boric acid and borax) has also well-described biological effects and therapeutic benefits. In a previous study, sister-chromatid exchanges

Polysaccharide-based hydrogels: preparation, characterization, and drug interaction behaviour.

Oxidized alginate (ADA) and oxidized alginate blended with chitosan (ADA-Chit) were prepared in the presence of borax and CaCl 2, and their interactions with an antifolate drug, pyrimethamine (PYR), have been investigated. Tablets with a mean diameter of 1.2 +/-

Determination of fumaric and maleic acids with stacking analytes by transient moving chemical reaction boundary method in capillary electrophoresis.

Jian-Feng He et al.

Journal of chromatography. A, 1218(24), 3816-3821 (2011-05-14)

The paper presents an on-line transient moving chemical reaction boundary (MCRB) method for simply but efficiently stacking analytes in capillary electrophoresis (CE). The CE technique was developed for a rapid determination of fumaric and maleic acid. Based on the theory
