Hidayani, W. A. published the artcileDetermination of the effect of EDTA and PCMB on purified bromelain activity from pineapple core and in vitro antiplatelet activity, Computed Properties of 104-01-8, the main research area is bromelain antiplatelet activity pineapple core enzyme.

Bromelain is an enzyme belongs to the cysteine protease. In this study, bromelain isolated from pineapple core (Ananascomosus [L.] Merr) was purified by fractionation using ammonium sulfate followed by dialysis and then ion exchange chromatog. The fraction of bromelain obtained from each purification step showed an increase in specific activity. The highest specific activity of protease was found in 20-50% ammonium sulfate fraction of 104.018 U/mg with a purity level 3.2-fold compared to crude extract Further purification by ion exchange chromatog. using DEAE-Cellulose, the fraction of bromelain showed an increase in specific activity to 278.333 U/mg with a purity level 8.8-fold compared to crude extract The determination of kinetics parameter of purified bromelain using Lineweaver-Burk plot gives Km value of 0.15% (w/v) and Vmax of 0.056 U/min. This bromelain can be strongly inhibited by EDTA and PCMB. The addition of EDTA and PCMB at a concentration of 0.5 mM can decrease the activity of the enzyme up to 88.50% by showing the competitive and mix-inhibition types of inhibition, resp. The antiplatelet activity of the bromelain fraction was tested in-vitro based on the Born method, by using plasma (PRP), acetosal as a pos. control and ADP as an aggregator. The purified bromelain showed the ability of an antiplatelet agent with percentage of aggregation 29.51% and percentage of inhibition 68.91%.

Guo, Jing published the artcileVisible-Light Catalyzed [1+2+2] Cycloaddition Reactions Enabled by the Formation of Methylene Nitrones, Safety of 4-Methoxyphenylacetic acid, the main research area is isoxazolidine preparation photochem; nitroarene alkene dimethylaniline cycloaddition iridium photocatalyst; aryl glycine alkene nitroarene cycloaddition iridium photocatalyst.

Herein, the first photo-redox synthesis of methylene nitrone intermediates from nitroarenes and arylamines were reported. The highly reactive methylene nitrones were in situ trapped by alkenes to afford various isoxazolidines. This three-component reaction features the use of N,N-dimethylanilines or N-aryl glycines as C1 building blocks, which allow for the one-pot formal [1+2+2] cycloaddition from simple starting materials. A wide range of useful isoxazolidines can be obtained under mild conditions with moderate to good yields. Mechanistic investigations supported the formation of methylene nitrone via selective N-CH3 bond cleavage and methylene transfer.

Cai, Chen-Yan published the artcileTailored cobalt-salen complexes enable electrocatalytic intramolecular allylic C-H functionalizations, Related Products of isoquinoline, the main research area is allylic carbamate ester intramol oxidative amination alkylation diastereoselective cobalt.

Oxidative allylic C-H functionalization is a powerful tool to streamline organic synthesis as it minimizes the need for functional group activation and generates alkenyl-substituted products amenable to further chem. modifications. The intramol. variants can be used to construct functionalized ring structures but remain limited in scope and by their frequent requirement for noble metal catalysts and stoichiometric chem. oxidants. Here authors report an oxidant-free, electrocatalytic approach to achieve intramol. oxidative allylic C-H amination and alkylation by employing tailored cobalt-salen complexes as catalysts. These reactions proceed through a radical mechanism and display broad tolerance of functional groups and alkene substitution patterns, allowing efficient coupling of di-, tri- and even tetrasubstituted alkenes with N- and C-nucleophiles to furnish high-value heterocyclic and carbocyclic structures.

Cheng, Wei-Chieh published the artcileRapid Synthesis of a Natural Product-Inspired Uridine Containing Library, COA of Formula: C9H10O3, the main research area is antibacterial morphol bacterial Bacillus subtilis nucleoside uridine preparation; click alkyne azide triazole cycloaddition catalyst preparation Bacillus subtilis; nucleoside uridine combinatorial library urea amide click preparation; chemical space; combinatorial chemistry; natural product-inspired nucleosides; semiautomated synthesis; uridine-containing library.

The preparation of natural product-inspired nucleoside analogs, e.g. I, using solution-phase parallel synthesis is described. The key intermediates containing alkyne and N-protected amino moieties were developed to allow for further skeleton and substituent diversity using click chem. and urea or amide bond formation. Rapid purification was accomplished using solid-phase extraction The obtained library comprised 80 mols. incorporating two diversity positions and one chiral center, each of which was efficiently prepared in good purity and acceptable overall yield. A bacterial morphol. study was also performed. None of the synthesized compounds were found to exhibit antibacterial activity against Gram-neg. bacterial strains such as A. baumannii at a concentration of 100μm, presumably because they could not penetrate the bacterial membranes (data not shown).

Arsene, Sobinson published the artcileImidazo[2,1-a]isoindole scaffold as an uncharted structure active on Leishmania donovani, SDS of cas: 104-01-8, the main research area is imidazoisoindoles leishmanicidal Leishmania infection energy metabolism; Antileishmanial activity; Energy metabolism; Imidazoisoindolols.

The human protozoan parasites Leishmania donovani and L. infantum are the causative agents of visceral leishmaniasis, as such, responsible for approx. 30,000 deaths annually. The available chemotherapeutic treatments are reduced to a few drugs whose effectiveness is limited by rising drug resistance/therapeutic failure, and noxious side-effects. Therefore, new therapeutic hits are needed. Compounds displaying the imidazo[2,1-a]isoindole skeleton have shown antichagasic, anti-HIV, antimalarial and anorectic activities. Here, we report the leishmanicidal activity of thirty one imidazo[2,1-a]isoindol-5-ol derivatives on promastigotes and intracellular amastigotes of L. donovani. Eight out of thirty one assayed compounds showed EC50 values ranging between 1 and 2 μM with selectivity indexes from 29 to 69 on infected THP-1 cells. Six compounds were selected for further elucidation of their leishmanicidal mechanism. In this regard, compound 29, the imidazoisoindolol with the highest activity on intracellular amastigotes, induced an early decrease of intracellular ATP levels, as well as mitochondrial depolarization, together with a partial plasma membrane destructuration, as assessed by TEM. Consequently, the inhibition of the energy metabolism of Leishmania plays an important role in the leishmanicidal mechanism of this compound, even when other addnl. targets cannot be ruled out. In all, the results supported the inclusion of the imidazoisoindole scaffold for the development of new leishmanicidal drugs.
