Sparkes, Emily I. published the artcileBiocatalytic Silylation: The Condensation of Phenols and Alcohols with Triethylsilanol, Category: alcohols-buliding-blocks, the publication is Catalysts (2021), 11(8), 879, database is CAplus.

Silicatein-α (Silα), a hydrolytic enzyme derived from siliceous marine sponges, is one of the few enzymes in nature capable of catalyzing the metathesis of silicon-oxygen bonds. It is therefore of interest as a possible biocatalyst for the synthesis of organosiloxanes. To further investigate the substrate scope of this enzyme, a series of condensation reactions with a variety of phenols and aliphatic alcs. were carried out. In general, it was observed that Silα demonstrated a preference for phenols, though the conversions were relatively modest in most cases. In the two pairs of chiral alcs. that were investigated, it was found that the enzyme displayed a preference for the silylation of the S-enantiomers. Addnl., the enzyme′s tolerance to a range of solvents was tested. Silα had the highest level of substrate conversion in the nonpolar solvents n-octane and toluene, although the inclusion of up to 20% of 1,4-dioxane was tolerated. These results suggest that Silα is a potential candidate for directed evolution toward future application as a robust and selective biocatalyst for organosiloxane chem.

Takeda, Kazuo published the artcileFe(II)/Cu(I)-dependent P-type ATPase activity in the liver of Long-Evans cinnamon rats, Quality Control of 85618-21-9, the publication is Life Sciences (2005), 76(19), 2203-2209, database is CAplus and MEDLINE.

This study examined Fe(II)-dependent ATPase activity in OTG (octylthioglucoside)-treated microsomes isolated from Wistar and LEC rats. The ATPase activity of the liver OTG-microsomes from Wistar rats increased sharply in the 5-150 μM range of Fe(II) with a K_0.5 value of 23.9 ± 3.6 μM, while the activity of LEC rat liver microsomes increased with increasing Fe(II) up to 500 μM with a K_0.5 value of 64.4 ± 8.1 μM. The K_0.5 values for Fe(II)-dependent ATPase activity of spleen OTG-microsomes were nearly identical at 59.3 μM in the Wistar rat and 63.7 μM in the LEC rats with a similar level of activity at each Fe(II) concentration in both strains of animals. These results indicated that there are two types of Fe(II)-dependent ATPase with different Fe(II) sensitivity, a high sensitive (H) and a low sensitive (L) type, and that the H-type activity was specific to the liver. The H-type activity was, however, deficient in the liver of LEC rats that accumulate copper and iron in hepatocytes as a result of mutations in the Wilson’s disease protein (WNDP). On the basis of these results, together with the similarity in optimal conditions required for full activity of the enzyme, we conclude that the Fe(II)-dependent ATPase (H-type) and WNDP may be identical.

Rosen, G. M. published the artcileNeuromuscular blocking activity of a series of β-haloethylamines, Synthetic Route of 101-98-4, the publication is Archives Internationales de Pharmacodynamie et de Therapie (1973), 204(2), 242-51, database is CAplus and MEDLINE.

The degree of irreversible neuromuscular blockade caused by 6 β-haloethylamines that exist in equilibrium between the linear from RNMeCH2CH2Cl and the aziridinium chloride form I, depends on the stability of the aziridinium ion. Thus when the aziridinium ion is either conjugated with the aromatic ring, such as in 2-chloroethylmethylphenylamine [1669-85-8], or separated from it by methylene groups to minimize interaction with the aromatic/ring the compounds act as reversible blocking agents. Irreversible blockade is produced by compounds, such as benzyl(2-chloroethyl)methoxyethylamine [50283-06-2] in which the aziridinium ion is stabilized by interaction with the non-bonding electrons, the ether O, or with the π-electrons of the aromatic ring.

Font, Bernard published the artcileInteraction of creatine kinase and hexokinase with the mitochondrial membranes, and self-association of creatine kinase: crosslinking studies, Related Products of alcohols-buliding-blocks, the publication is Molecular and Cellular Biochemistry (1987), 78(2), 131-40, database is CAplus and MEDLINE.

Covalent coupling of protein by crosslinking reagents has been used to study the interaction of mitochondrial creatine kinase (CKm) and hexokinase (HK) with the mitochondrial membranes. The effects of crosslinkers were studied either by following the inhibition of solubilization of enzymic activities or by modification of the electrophoretic patterns of proteins solubilized from mitochondria after treatment with different crosslinkers. Dimethylsuberimidate (DMS) efficiently reduced the amount of HK activity solubilized by various agents but it did not modify solubilization of CKm from mitochondria. The effect of DMS on HK solubilization did not result from nonspecific crosslinking since it did not impede the solubilization of adenylate kinase. The bissuccinimidyl class of crosslinkers was also tested. Ethyleneglycolbis(succinimidylsuccinate) (EGS) efficiently reduced HK solubilization, but it addnl. induced osmotic stabilization of mitochondria and thus impeded release of soluble or solubilized proteins from the intermembrane space. Furthermore, this agent drastically inhibited CKm activity and thus, in a second set of experiments the effect of crosslinkers were studied by the disappearance of protein bands in the electrophoretic pattern of soluble fractions obtained from mitochondria, the outer membranes of which have been ruptured to allow free release of soluble proteins. Results of these experiments showed that succinimidyl reagents and Cu²⁺-phenanthroline substantially reduced the amount of CKm released from mitochondria and confirmed that bisimidates were ineffective in inhibiting CKm solubilization. In addition, crosslinking reagents were used to study subunit interactions in purified CKm. The results showed, in contrast with control experiments with a monomeric protein (ovalbumin) which did not give rise to polymers, that under the same conditions, electrophoresis of crosslinked CKm resolved a set of species with mol. weights roughly equal to integral multiples of the protomer. These results prove that the polymeric form of CKm is an octamer.

Freichel, Tanja published the artcileToward orthogonal preparation of sequence-defined monodisperse hetero-multivalent glyco-macromolecules on solid support using Staudinger ligation and copper-catalyzed click reactions, Category: alcohols-buliding-blocks, the publication is Journal of Organic Chemistry (2017), 82(18), 9400-9409, database is CAplus and MEDLINE.

The investigation of hetero-multivalent interactions of complex glyco-ligands and proteins is critical for understanding important biol. processes and developing carbohydrate-based pharmaceutics. Synthetic glycomimetics, derived by mimicking complex glyco-ligands on a variety of scaffolds, have become important tools for studying the role of carbohydrates in chem. and biol. In this paper, we report on a new synthetic strategy for the preparation of mono-disperse, sequence-defined glyco-oligomers or so-called precision glyco-macromols. based on solid phase oligomer synthesis and the Staudinger ligation. This strategy employs a solid-supported synthetic approach using a novel carboxy-functionalized building block which bears a functional handle required for Staudinger ligation on solid support. Furthermore, we combined Staudinger ligation and copper catalyzed azide alkyne cycloaddition (CuAAC) reactions to synthesize hetero-multivalent glyco-oligomers on solid support for the first time, demonstrating the utility of this approach for the synthesis of hetero-functional glyco-macromols.

Mengozzi, Luca published the artcilePhenoxyaluminum(salophen) Scaffolds: Synthesis, Electrochemical Properties, and Self-Assembly at Surfaces of Multifunctional Systems, Recommanded Product: 4-(1H-Pyrrol-1-yl)phenol, the publication is Chemistry – A European Journal (2018), 24(46), 11954-11960, database is CAplus and MEDLINE.

Salophens and Salens are Schiff bases generated through the condensation of two equivalent of salicylaldehyde with either 1,2-phenylenediamines or aliphatic diamines, resp. Both ligands have been extensively exploited as key building blocks in coordination chem. and catalysis. In particular, their metal complexes have been widely used for various catalytic transformations with high yield and selectivity. Through the modification of the phenol unit it is possible to tune the steric hindrance and electronic properties of Salophen and Salen. The introduction of long aliphatic chains in salicylaldehydes can be used to promote their self-assembly into ordered supramol. structures on solid surfaces. Herein, the authors report a novel method towards the facile synthesis of robust and air-stable [Al(Salophen)] derivatives capable of undergoing spontaneous self-assembly at the graphite/solution interface forming highly-ordered nanopatterns. The new synthetic approach relies on the use of [MeAl^III(Salophen)] as a building unit to introduce, via a simple acid/base reaction with functionalized acidic phenol derivatives, selected frameworks integrating multiple functions for efficient surface decoration. STM imaging at the solid/liquid interface made it possible to monitor the formation of ordered supramol. structures. In addition, the redox properties of the Salophen derivatives functionalized with ferrocene units in solution and on surface were unraveled by cyclic voltammetry. The use of a five-coordinate aluminum alkyl Salophen precursor enables the tailoring of new Salophen mols. capable of undergoing controlled self-assembly on HOPG, and thereby it can be exploited to introduce multiple functionalities with subnanometer precision at surfaces, ultimately forming ordered functional patterns.
