4-Amino-3-[2-(9H-carbazol-9-yl)ethyl]-1H-1,2,4-triazole-5(4H)-thione dimethyl sulfoxide monosolvate

IUCrData, 2016
In the crystal of the title compound, C16H15N5S·C2H6OS, both the 1,2,4-triazole derivative molecules and the disordered [refined occupancy ratio = 0.604 (1):0.396 (1)] dimethyl sulfoxide solvent molecules form centrosymmetric dimers, by way of pairwise N—

Toward Chromoselective Transformations in Biological Systems: Perspectives and Challenges

Angewandte Chemie International Edition, EarlyView.
Controlling biological systems with small‐molecule chromophores has evolved into a powerful strategy and is applied from chemical biology to medicine. However, the complexity of in vivo systems cannot be matched by a single wavelength of light. Developing methods to combine and individually control multiple chromophores is crucial.

1,3,6-Tribromo-9-ethyl-9H-carbazole

IUCrData, 2016
In the title compound, C14H10Br3N, the carbazole ring system is almost planar, with an r.m.s. deviation of 0.023 Å from the best fit mean plane of the 13 non-H atoms of the three rings. The methyl C atom lies 1.232 (3) Å out of this plane.

Unlocking Catalyst Activation as a Critical Bottleneck in Cross‐Coupling Reactions: Room‐Temperature Couplings of Weak Nucleophiles Enabled by [Pd(1‐MeNAP)TFA]2 Precatalysts

Angewandte Chemie International Edition, EarlyView.
In many Pd‐catalyzed cross‐couplings, catalyst performance has been found to be limited by catalyst activation. Methylnaphthyl (MeNAP) palladium trifluoroacetate dimers are presented as easy‐to‐store and easy‐to‐handle precursors, which rapidly activate under reaction conditions, even when only weakly coordinating, non‐reducing nucleophiles are present.

Oxidation of Carbazole.

Journal of Synthetic Organic Chemistry, Japan, 1965
In the oxidation of carbazole, two isomers of dicarbazyl are formed as main reaction products. 3, 3'-Dicarbazyl is formed by bichromate or permanganate oxidation in acetic acid, whereas 9, 9'-dicarbazyl is formed by permanganate oxida tion in acetone.

Effects of Lycium barbarum Residue Substituting Dietary Maize on Fecal Microbiota and Growth Performance of Crossbred Simmental Cattle

Animal Research and One Health, EarlyView.
The bioactive substances we extracted from Lycium barbarum residue (LBR) have a typical polysaccharide structure. When 1.80% LBR was used to replace maize in the diet, the average daily gain of rossbred Simmental was significantly increased, and anti‐inflammatory ability was improved. In addition, LBR improved the fecal microbial composition, increased

Atomically precise metal cluster enzymes for pathological tissue regeneration

BMEMat, EarlyView.
Schematic illustration of atomically precise metal cluster enzymes (MCEs) for pathological tissue regeneration. Atomically precise MCEs can modulate biological processes, such as attenuation of inflammatory responses, eradication of bacterial pathogens, regulation of angiogenesis, and promotion of cell development.

Distinct Ligand‐ and Metal‐Centered Phosphorescence in a Terbium Carbazolyl Complex

Chemistry – A European Journal, EarlyView.
Terbium and lanthanum carbazolide complexes show two distinct modes of luminescence: Strongly temperature‐dependent narrow‐line terbium emission could be induced. In addition, both the terbium and the lanthanum complexes show broad‐line interligand emission processes with excited states of microsecond life‐time.
