Development of human antimouse antibody (HAMA) is a major limiting factor in the application of murine mAb for clinical use. A novel immunomodulatory drug, deoxyspergualin (DSG), has shown potential to suppress antimouse antibody response in preclinical model systems. We conducted a Phase I trial to determine the effect of DSG on HAMA response to murine mAb L6 administered to patients with adva...

The title compound, [Pd(NH3)4]Cl2·4NH3, was crystallized in liquid ammonia from the salt Pd(en)Cl2 (en is ethylenediamine) and is isotypic with [Pt(NH3)4]Cl2·4NH3 [Grassl & Korber (2014 ▶). Acta Cryst. E70, i31]. The Pd(2+) cation is coordinated by four ammonia mol-ecules, exhibiting a square-planar geometry. The chloride anions are surrounded by nine ammonia mol-ecules. These are either bound ...

The title compound, K(2)Sm(MoO(4))(PO(4)), has been prepared under atmospheric conditions using a high temperature solution growth (HTSG) method. The structure of K(2)Sm(MoO(4))(PO(4)) is isotypic with other A(2)M(MoO(4))(PO(4)) compounds, where A = Na or K, and M = trivalent rare earth cation. It can be described as being built up from two-dimensional anionic layers with composition [Sm(MoO(4)...

The title compound, (CH(6)N)(2)[WS(4)], was synthesized by the reaction of ammonium tetra-sulfidotungstate(VI) with aqueous methyl-amine. The title compound is isotypic with the corresponding Mo analogue (CH(6)N)(2)[MoS(4)], and its structure consists of a slightly distorted tetra-hedral [WS(4)](2-) dianion and two crystallographically independent methyl-ammonium (MeNH(3)) cations, all of which...

Reaction of cobalt(II) nitrate with potassium seleno-cyanate and pyridazine leads to single crystals of the title compound, [Co(NCSe)(2)(C(4)H(4)N(2))(4)]·2C(4)H(4)N(2), which is isotypic with its nickel(II) thio-cyanate analogue. The Co(2+) cations are coordinated by two N-bonded seleno-cyanate ligands and four N atoms from four pyridazine ligands into discrete complexes. The complexes are arr...

In comparison with the original determination based on Weissenberg film data [Khan et al. (1970 ▶). Acta Cryst. B26, 1889-1892], the current redetermination of diammonium hydrogenarsenate(V) reveals all atoms with anisotropic displacement parameters and all H atoms localized. This allowed an unambiguous assignment of the hydrogen-bonding pattern, which is similar to that of the isotypic phospha...

Colorless transparent single crystals of trilanthanum hexa-silicon undeca-nitro-gen, La3Si6N11, were prepared at 0.85 MPa of N2 and 2273 K. The title compound is isotypic with Sm3Si6N11. Silicon-centered nitro-gen tetra-hedra form a three-dimensional network structure by sharing their corners. Layers of one type of SiN4 tetra-hedra and slabs composed of the two different La(3+) cations and the ...

In the mol-ecules of the two isotypic title compounds, C18H11Br2N3O4 (I) and C18H11Cl2N3O4 (II), the tri-phenyl-amine N atoms show no sign of pyramidalization, with marginal displacements of the N atoms from the mean plane of the three connecting C atoms: 0.0058 (13) Å for the Br compound (I) and 0.0074 (9) Å for the Cl compound (II). In the crystals, mol-ecules are linked through C-H⋯O hydroge...

In the centrosymmetric binuclear title complex, [Pr(2)(C(9)H(9)O(3))(6)(C(12)H(8)N(2))(2)], the two Pr(III) ions are linked by four 2-phen-oxy-propionate (L) groups through their bi- and tridentate bridging modes. Each Pr(III) ion is nine-coordinated by one 1,10-phenanthroline mol-ecule, one bidentate carboxyl-ate group and four bridging carboxyl-ate groups in a distorted PrN(2)O(7) monocapped ...
