Incorporation of a nitrogen functionality into a tripodal N-heterocyclic carbene ligand system affords the first N-anchored tetradentate tris-carbene ligands TIMEN(R) (R = Me (5a), t-Bu (5b), Bz (5c)). Treatment of the methyl derivatized [H(3)TIMEN(Me)](PF(6))(3) imidazolium salt (H(3)5a) with silver oxide yields the silver complex [(TIMEN(Me))(2)Ag(3)](PF(6))(3) (9), which, in a ligand transfe...
The human mitochondrial cytochrome P450 enzymes CYP11A1, CYP11B1, and CYP11B2 are involved in the biosynthesis of steroid hormones.CYP11A1 catalyzes the side-chain cleavageof cholesterol, and CYP11B1 and CYP11B2 catalyze the final steps in the biosynthesis of glucoand mineralocorticoids, respectively. This study reveals their additional capability tometabolize the xenobiotic steroid oral turina...
A 6.29-Mb genome sequence of Cyclobacterium qasimii strain M12-11B(T), isolated from an Arctic marine sediment sample, is reported.
The subcellular distribution of microtubules containing acetylated alpha-tubulin in mammalian cells in culture was analyzed with 6-11B-1, a monoclonal antibody specific for acetylated alpha-tubulin. Cultures of 3T3, HeLa, and PtK2 cells were grown on coverslips and observed by immunofluorescence microscopy after double-staining by 6-11B-1 and B-5-1-2, a monoclonal antibody specific for all alph...
The title compound, C(13)H(10)N(4)O(2)S, was prepared through a cyclization reaction of 1,10-phenanthroline-5,6-dione and thio-urea. The dihedral angle between the pyridine rings is 8.22 (2)°. In the crystal, mol-ecules are connected by N-H⋯O, O-H⋯N, N-H⋯S and O-H⋯S hydrogen bonds, forming a three-dimensional network.
