The enzymes that degrade proteins to peptides for presentation on MHC class II molecules are poorly understood. The cysteinal lysosomal proteases, cathepsin L (CL) and cathepsin S (CS), have been shown to process invariant chain, thereby facilitating MHC class II maturation. However, their role in Ag processing is not established. To examine this issue, we generated embryonic fibroblast lines t...

In the title compound, [ZnCl(2)(C(15)H(16)N(2))]·CH(2)Cl(2), the Zn(II) atom has a distorted tetra-hedral coordination by two Cl atoms and two N atoms from the organic ligand [the average Zn-N and Zn-Cl bond lengths are 2.060 (4) Å and Zn-Cl = 2.179 (16) Å, respectively]. The dihedral angle between the N-Zn-N and Cl-Zn-Cl planes is 89.9 (1)°. The phenyl ring forms a dihedral angle of 40.6 (5)° ...

A density functional theory study of the magnetic couplings in Sr2V3O9 type magnetic oxides suggests that whereas the intrachain coupling is always weakly ferromagnetic, the interchain coupling may be antiferromagnetic or even weakly ferromagnetic depending on the nature of the central tetrahedral atom (As/V) cations, and, to a lesser extent, structural details.

Seven Zn(II) coordination complexes with 5-halonicotinic acids (HL-X, X = F, Cl, or Br) have been synthesized with different synthetic approaches, including layer diffusion or stirring method in an ambient environment and solvothermal synthesis at 100 °C. Assembly of HL-F with Zn(II) under different conditions will yield the same 2D network of [Zn(L-F)2]n (1). Interestingly, three distinct comp...

Platelet-activating factor (PAF) is a phospholipid inter- and intracellular mediator implicated in intestinal injury primarily via induction of an inflammatory cascade. We find that PAF also has direct pathological effects on intestinal epithelial cells (IEC). PAF induces Cl(-) channel activation, which is associated with intracellular acidosis and apoptosis. Using the rat small IEC line IEC-6,...

The title compound, [CuCl(2)(C(18)H(18)N(8))]·2CH(3)OH·H(2)O, contains a penta-coordinated Cu(II) atom bonded to the tridentate 4,6-bis-[(E)-1-methyl-2-(pyridin-2-yl-methyl-idene)hydrazin-yl]pyrimidine ligand and two Cl atoms. The geometry around the Cu(II) atom is distorted square-pyramidal. The mol-ecules pack in the crystal structure via O-H⋯Cl, O-H⋯N, C-H⋯Cl and C-H⋯O hydrogen bonds, C-H⋯π ...

In the crystal structure of the title compound, [ZnCl(2)(C(5)H(4)ClN)(2)], discrete complex mol-ecules are found in which the Zn(II) cations are coordinated by two chloride anions and the N atoms of the two 3-chloro-pyridine ligands within a slightly distorted tetra-hedron. Moreover, inter-molecular C-Cl⋯Cl-C halogen inter-actions (Cl⋯Cl = 3.442 Å) are found between the building blocks.

In the polymeric title complex, [CdCl(2)(C(12)H(13)N(5))](n), the Cd(II) atom is five-coordinated by two N atoms from two bridging 1-[(2-ethyl-1H-imidazol-1-yl)meth-yl]-1H-benzotriazole (bmei) ligands, two bridging Cl atoms and one terminal Cl atom in a distorted trigonal-bipyramidal geometry. The Cd(II) atoms are connected alternately by the Cl atoms and bmei ligands, leading to a zigzag chain...

In the title compound, [PtCl2(C21H21O3P)2]·2C3H6O, the asymmetric unit contains a Pt(II) ion situated on an inversion center, one chloride anion, one tris-(4-meth-oxy-lphen-yl)phosphane (L) ligand and one acetone solvent mol-ecule. The Pt(II) ion is coordinated by two P atoms [Pt-P = 2.3196 (5) Å] from two L ligands and two chloride anions [Pt-Cl = 2.3075 (5) Å] in a distorted square-planar geo...

The cyanamides NCNR2 (R2 = Me2, Ph2, C5H10) react with ZnX2 (X = Cl, Br, I) in a 2 : 1 molar ratio at RT, giving a family of zinc(ii) complexes [ZnX2(NCNR2)2] (R2 = Me2, X = Cl , X = Br , X = I ; R2 = C5H10, X = Cl , X = Br ; X = I ; R2 = Ph2, X = Cl , X = Br , X = I ; 75-92% yields). Complexes and undergo ligand redistribution in wet CH2Cl2 solutions giving the [Zn(NCNPh2)4(H2O)2][Zn2(μ-X)2X4]...
