Performing a heterogeneous catalysis with proteins is still a challenge. Herein, we demonstrate the importance of cross‐linked crystals for sulfoxide oxidation by an artificial enzyme. The biohybrid consists of the insertion of an iron complex into a NikA protein crystal. The heterogeneous catalysts displays a better efficiency‐with higher reaction kinetics, a better stability and expand the substrate

A series of substituted3,4-dihydro-2H-1,4-thiazines inhibit 5-lipoxygenase from rat leukocytes and exhibit submicromolar IC50 values. A novel synthesis of these compounds was developed based on the formation of hydroxymethyleneamine 13 and its cyclization to the title compounds. The dihydrothiazines have low oxidation potentials, typically E1/2 is near 0.3 V, and a representative compound reduces
Extraction and coordination studies of the unexplored bifunctional ligand carbamoyl methyl sulfoxide (CMSO) with uranium(vi) and cerium(iii) nitrates. Synthesis and structures of [UO2(NO3)2(PhSOCH2CONiBu2)] and [Ce(NO3)3(PhSOCH2CONBu2)2]

PhSOCH2CONBu2 (L44), PhSOCH2CONiBu2 (L55) and PhSOCH2CON(C8H17)2 (L66) have been synthesized and characterized by spectroscopic methods. The selected coordination chemistry of L11, L33, L44 and L55 with [UO2(NO3)2] and [Ce(NO3)3] has been evaluated. The structures of the compounds [UO2(NO3)2(PhSOCH2CONiBu2)] (10) and [Ce(NO3)3(PhSOCH2CONBu2)2] (12) have been determined by single crystal X-ray diffraction
