We previously developed a dithienylcyclopentene dopant that bears two methylenedioxy-bridged binaphthyl moieties. Herein, we report our new findings on related compounds that entail different bridge lengths in their binaphthyl units. Three new compounds were synthesized. It was found that variations of the bridge length resulted in significantly different photoresponsive properties in LC media.

Qiang, Wen published the artcileImpact of the gut microbiota on heat stroke rat mediated by Xuebijing metabolism, SDS of cas: 637-07-0, the publication is Microbial Pathogenesis (2021), 104861, database is CAplus and MEDLINE.

The goal of the present study was to evaluate the fecal microbiome and serum metabolites in Xuebijing (XBJ)-injected rats after heat stroke using 16S rRNA gene sequencing and gas chromatog.-mass spectrometry (GC-MS) metabolomics. Eighteen rats were divided into the control group (CON), heat stroke group (HS), and XBJ group. The 16S rRNA gene sequencing results revealed that the abundance of Bacteroidetes was overrepresented in the XBJ group compared to the HS group, while Actinobacteria was underrepresented. Metabolomic profiling showed that the pyrimidine metabolism pathway, pentose phosphate pathway, and glycerophospholipid metabolism pathway were upregulated in the XBJ group compared to the HS group. Taken together, these results demonstrated that heat stroke not only altered the gut microbiome community structure of rats but also greatly affected metabolic functions, leading to gut microbiome toxicity.

Barrios-Rivera, Jonathan published the artcileAsymmetric Transfer Hydrogenation of Unhindered and Non-Electron-Rich 1-Aryl Dihydroisoquinolines with High Enantioselectivity, Quality Control of 620-20-2, the publication is Organic Letters (2020), 22(16), 6283-6287, database is CAplus and MEDLINE.

The use of arene/Ru/TsDPEN catalysts bearing a heterocyclic group on the TsDPEN in the asym. transfer hydrogenation (ATH) of dihydroisoquinolines (DHIQs) containing meta- or para-substituted aromatic groups at the 1-position results in the formation of products of high enantiomeric excess. Previously, only 1-(ortho-substituted)aryl DHIQs, or with an electron-rich fused ring gave products with high enantioselectivity; therefore, this approach solves a long-standing challenge for imine ATH.

A series of (S)-tryptamine derivatives containing an allyl group and an aryl sulfonamide unit, I (R = Ph, 3-Cl-4-FC₆H₃, 4-Br-2-ClC₆H₄, etc.) and II [R = Ph, 2,4,6-(Me₂CH)₃C₆H₂], were designed, synthesized and evaluated for their potential application as anticancer agents. The structures of the synthesized compounds were characterized by ¹H NMR, ¹³C NMR and ESI-MS spectral analyses. The target compounds were evaluated for their in vitro cytotoxicity against HepG2, HeLa, CNE1 and A549 human cancer cell lines. Some of the synthesized compounds showed moderate to good anticancer activities against four selected cancer cell lines, among of which I [R = 2,4,6-(Me₂CH)C₆H₂] (III) was found to be the most active analog possessing IC₅₀ values 16.5-18.7 μM. Further mechanism studies revealed that compound III could significantly induce HepG2 cell cycle arrest at G1 phase, promote cell apoptosis, and inhibit the colony formation as well.
