The combination of Pd(TFA)2 and an N,N’-disulfonyl bisimidazoline ligand shows high catalytic activity and excellent asym. induction in the addition of arylboronic acids to cyclic N-sulfonyl ketimines including benzo[d]isothiazole-1,1-dioxides, benzo[e][1,2,3]oxathiazine-2,2-dioxides, and 1,2,5-thiadiazole-1,1-dioxides, by which three types of chiral quaternary carbon-containing sultams with substantial substitution diversity were synthesized with high yields and excellent enantioselectivities (up to >99% ee). The current catalysis demonstrated a remarkable tolerance to oxygen and thus provided an operationally simple approach for constructing enantioenriched cyclic quaternary stereocenters.

The article was titled 《Pd-Catalyzed Direct Diversification of Natural Anti-Alzheimer’s Disease Drug: Synthesis and Biological Evaluation of N-Aryl Huperzine A Analogues》.SDS of cas: 2398-37-0 The article contains the following contents:

The first systematic direct diversification of a complex natural product by metal-catalyzed N-H functionalization was carried out. A new series of N-(hetero)aryl analogs I (Ar = Ph, 2-naphthyl, 4-methylpyridin-2-yl, etc.) of the natural anti-Alzheimer’s disease drug huperzine A (HPA) was prepared via palladium-catalyzed Buchwald-Hartwig cross-coupling reactions of HPA with various aryl bromides ArBr in good yields. Most of the N-aryl-huperzine A (N-aryl-HPA) analogs showed good acetylcholinesterase (AChE) inhibitory activity in in vitro experiments Three arylated huperzine A analogs I (Ar = 4-FC6H4, 4-methoxy-2,6-dimethylphenyl, 5-methoxypyridin-2-yl) exhibited stronger anti-AChE activity than HPA. The 5-methoxy-2-pyridyl analog I (Ar = 5-methoxypyridin-2-yl) displayed the most potent AChE inhibition activity, with an IC50 value of 1.5μM, which was 7.6-fold more active than HPA. Compound I (Ar = 5-methoxypyridin-2-yl) also exhibited better neuroprotective activity for H2O2-induced damage in SH-SY5Y cells than HPA. Structure-activity relationship anal. suggested that the electron d. of the installed aromatic ring or heteroaromatic ring played a significant role in inducing the AChE inhibition activity. Overall, compound I (Ar = 5-methoxypyridin-2-yl) showed the advantages of easy synthesis, high potency and selectivity, and improved neuroprotection, making it a potential huperzine-type lead compound for Alzheimer’s disease drug development.

The article was titled 《Synthesis of Enantioenriched 3,4-Disubstituted Chromans Through Lewis-Base Catalyzed Carbosulfenylation》.COA of Formula: C7H8O2 The article contains the following contents:

A method for the catalytic, enantioselective, carbosulfenylation of alkenes to construct 3,4-disubstituted chromans was described. Alkene activation proceeded through the intermediacy of enantioenriched, configurationally stable, thiiranium ions generated from catalytic Lewis-base activation of an electrophilic sulfenylating agent. The transformation affords difficult to generate enantioenriched 3,4-disubstituted chromans in moderate to high yields and excellent enantioselectivities. A variety of substituents are compatible including electronically diverse functional groups as well as several functional handles such as aryl halides, esters, anilines, and phenols. The resulting thioether moiety was amenable to a number of functional group manipulations and transformations. Notably, the pendant sulfide was successfully cleaved to furnish a free thiol which readily provides access to most sulfur-containing functional groups which are present in natural products and pharmaceuticals. The experimental part of the paper was very detailed, including the reaction process of m-Methoxyphenol(cas: 150-19-6COA of Formula: C7H8O2)

Calculated data are in good accordance with the exptl. studies. The in vitro biol. activities of the synthesized ligands and their copper(II) complexes were evaluated against Staphylococcus aureus and Escherichia coli. The activity data showed that the metal complexes have a promising biol. potential comparable with the parent Schiff base ligands against bacterial species.

The article was titled 《CD271+CD51+PALLADIN- Human Mesenchymal Stromal Cells Possess Enhanced Ossicle-Forming Potential》, and you may find the article in Stem Cells and Development.Product Details of 106685-40-9 The information in the text is summarized as follows:

Human mesenchymal stem/stromal cells (hMSCs), when engrafted into immunodeficient mice, can form ectopic bone organs with hematopoietic stem cell (HSC) supportive functions. However, the ability to do so, through a cartilage intermediate, appears limited to 30% of donor bone marrow samples. In this study, we characterize the heterogeneous nature of hMSCs and their ability to efficiently form humanized ossicles observed in “”good donors”” to correlate with the frequency and functionality of chondrocyte progenitors. Flow cytometry of putative hMSC markers was enriched in the CD271+CD51+ stromal cell subset, which also possessed enhanced hMSC activity as assessed by single-cell colony-forming unit fibroblast (CFU-F) and undifferentiated mesensphere formation. Transcriptome anal. of CD271+ cells presented upregulation of chondrogenesis-/osteogenesis-related genes and HSC/niche maintenance factors such as C-X-C motif chemokine 12 (CXCL12) and ANGIOPOIETIN 1. Among the candidate genes selected to enrich for subsets with greater chondrogenic ability, cells neg. for the actin cross-linker PALLADIN displayed the greatest CFU-F potential. Our study contributes to a better characterization of ossicle-forming hMSCs and their efficient isolation for the optimized engineering of human bone organs.

In this work, new sulfonylhydrazone compounds with alkyl derivatives (SH1- SH4 series) were synthesized via a green chem. method, and their inhibition effects on acetylcholinesterase and butyrylcholinesterase (AChE, BChE) were determined in vitro. This work was designed in two stages; in the first stage, using compounds that contain both sulfonamide and hydrazine groups which have important pharmacol. properties, a series of sulfonyl hydrazone with alkyl derivatives (SH1- SH4) were synthesized with a method that is less time-consuming and more environmentalist that was by using different substitute groups containing aldehyde and ketone compounds The structures of the synthesized compounds were characterized by elemental analyses, 1H NMR, 13C NMR, FT-IR methods. In the second stage, the effects of the synthesized sulfonyl hydrazones with alkyl derivatives on acetylcholinesterase and butyrylcholinesterase enzymes were examined According to the results, all the synthesized compounds inhibited AChE and BChE enzymes. When the IC50 values were compared, SH2-3 (IC50 = 5.27 ± 0.05 μM) and SH3-3 (IC50 = 12.29 ± 1.47 μM) compounds which are containing the Bu group have the best inhibition effect on the AChE enzyme and BChE enzyme, resp. In addition, the predictive properties of all compounds in terms of drug similarity were scanned using five Lipinski rules and ADME estimations In silico ADME studies play an important role in improving and predicting drug compounds In the ADME study; The absorption, distribution, metabolism, elimination, and properties of the mols. given below were theor. calculated Also, to evaluate the binding interactions between the sulfonylhydrazone compounds and enzymes, mol. docking studies were performed and the compounds with the best inhibition effect SH2-3 (for AChE enzyme) and SH3-3 (for BChE enzyme) were tested. Both in vitro and silico the results showed that two compounds could act as potent inhibitors of AChE, BChE. The results came from multiple reactions, including the reaction of 2-Hydroxy-4-methoxybenzaldehyde(cas: 673-22-3Reference of 2-Hydroxy-4-methoxybenzaldehyde)
