Thiazolidin-2-cyanamides derivatives as novel potent Escherichia coli β-glucuronidase inhibitors and their structure–inhibitory activity relationships

Journal of Enzyme Inhibition and Medicinal Chemistry, 2020
Gut microbial β-glucuronidases have the ability to deconjugate glucuronides of some drugs, thus have been considered as an important drug target to alleviate the drug metabolites-induced gastrointestinal toxicity.

Recent Synthetic Advances in C–H/N–H Functionalization of 1H‐Pyrazoles: Diverse Strategies Across Variously Substituted Scaffolds

The Chemical Record, EarlyView.
Systematic overview of pyrazole functionalization reactions from C‐5 to N−H. It covers different strategies, from traditional cross‐coupling of prefunctionalized pyrazoles to more efficient direct functionalizations. This review briefly and systematically overviews C–H and N–H functionalization reactions of pyrazoles, aimed at creating new CC and C ...

Characterizing Gallium Dinitridocarbonates: A Focus on LiGa(CN2)2, Li13.6Ga2.8(CN2)10I2, and SrGa2(CN2)4

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
Three ternary gallium carbodiimides were synthesized via solid‐state metathesis reaction. The stable compound SrGa2(CN2)4 is showing a band gap in the order of 3 eV, LiGa(CN2)2 represents a carbodiimide‐cyanamide and Li13.6Ga2.8(CN2)10I2 contains disordered lithium ions.

Synthesis of 4H-Benzo[e][1,3]oxazin-4-ones by a Carbonylation–Cyclization Domino Reaction of ortho-Halophenols and Cyanamide [PDF]

, 2017
A mild and convenient one-step preparation of 4H-1,3-benzoxazin-4-ones by a domino carbonylation–cyclization process is developed. Readily available ortho-iodophenols are subjected to palladium-catalyzed carbonylative coupling with Mo(CO)6 and cyanamide,

Synthesis and Characterization of the Ternary Carbodiimide Na2Hf(NCN)3

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
The ternary carbodiimide Na2Hf(NCN)3, synthesized through solid‐state metathesis, crystallizes in a low‐symmetry variant of the [NiAs]‐type structure, featuring alternating layers of bent carbodiimide units and metal cations. As experimentally observed and due to electrostatic considerations, the R3¯c space group was found to be favored over the Pnna ...

Mystery and misery of locally‐delivered drug therapy in periodontics. Historical concepts and current state

Periodontology 2000, EarlyView.
Abstract The primary objective is to critically analyze approaches to local therapy for periodontal disease, particularly in light of its well‐established systemic implications. We specifically address common misconceptions and overestimations regarding the potential of local treatments in contrast to their actual clinical effectiveness.
