De‐Saturation of Single‐Atom Copper Catalysts for Accelerating Propargylic Substitution Reactions
Advanced Materials, EarlyView.De‐saturation of copper‐based single‐atom catalysts (De‐sat SACs) are realized by a KOH‐mediated Joule thermal shock strategy. Benefiting from the under‐saturation coordination environment of single‐atom Cu center, De‐sat Cu SACs exhibit remarkable catalytic activity in propargylic substitution reactions, tolerating a broad range of nucleophiles (N–, C–

Toxicokinetic and mass balance of morpholine in rats
Xenobiotica, 2023 Morpholine (MOR) has a broad spectrum of use and represents high risk of human exposure. Ingested MOR can undergo endogenous N-nitrosation in the presence of nitrosating agents forming N-nitrosomorpholine (NMOR), classified as possible human carcinogen by the International Agency for Research on Cancer.In this study, we evaluated the MOR toxicokinetics

Synthesis of Morpholine Containing Sulfonamides: Introduction of Morpholine Moiety on Amine Functional Group [PDF]
Journal of Chemistry, 2004 Sulfonamides have been the center of drug structures as this group is quite stable & well tolerated in human beings. The synthesis of these structures was started in search of new pharmacological active reagents. These compounds are being tested for the desired activity (ICAM‐1/LFA‐1 Interaction inhibitors as anti‐adhesion therapeutic agents), the ...

Potassium morpholine-4-carbodithioate monohydrate [PDF]
Acta Crystallographica Section E Structure Reports Online, 2012 In the ionic title compound, K+·C5H8NOS2−·H2O, the morpholine ring of the morpholine-4-carbodithioate anion has a chair conformation. The potassium cation is coordinated by four S and four O atoms in a bipyramidal reversed geometry. In the crystal, the three components are linked, generating infinite two-dimensional networks that lie parallel to ...

Vacuolar H+-Pyrophosphatase AVP1 is Involved in Amine Fungicide Tolerance in Arabidopsis thaliana and Provides Tridemorph Resistance in Yeast [PDF]
, 2016 Amine fungicides are widely used as crop protectants. Their success is believed to be related to their ability to inhibit postlanosterol sterol biosynthesis in fungi, in particular sterol-Δ8,Δ7-isomerases and sterol-Δ14-reductases, with a concomitant ...
