In the crystal structure of the title compound, [Cu(C(18)H(16)N(6))(C(36)H(28)OP(2))]PF(6)·0.5CH(2)Cl(2) or [Cu(DPEPhos)(Bn-bta)]PF(6)·0.5CH(2)Cl(2) {DPEPhos = bis-[(diphenyl-phosphan-yl)phen-yl] ether and Bn-bta = 1,1'-dibenzyl-1H,1'H-4,4'-bi-1,2,3triazol-e}, the Cu atom is coordinated by two N and two P atoms of the ligands in a strongly distorted tetra-hedral environment. There are two cryst...

Immunotherapy using adoptive cell transfer is a promising approach that can result in the regression of bulky, invasive cancer in some patients. However, currently available therapies remain less successful than desired. To study the mechanisms of action and possible improvements in cell-transfer therapies, we use a murine model system with analogous components to the treatment of patients. T c...

A novel hybrid material (SBA-P1) is prepared through the functionalization of mesoporous silica (SBA-15) with a 1,8-naphthalimide-based dye by sol-gel reaction. The characterization results of elemental analysis (EA), X-ray powder diffractometer (XRD) and spectroscopic methods demonstrate the fluorescence dye P1 is successfully grafted onto the inner surface of SBA-15 and the organized structur...

In the title compound, [Mn(C(7)H(5)O(3))(2)(C(14)H(12)N(2))(H(2)O)]·C(14)H(12)N(2)·H(2)O, the Mn(II) ion is coordinated by a bidentate 2,9-dimethyl-1,10-phenanthroline (dmphen) ligand, two monodentate 3-hydroxy-benzoate anions (3-HBA) and one water mol-ecule in a distorted trigonal-bipyramidal environment. An uncoordinated dmphen and an uncoordinated water mol-ecule cocrystallized with each com...

Interleukin-15 (IL-15), a product of monocytes and other cells, has biological activities similar to those of IL-2, including growth stimulation of activated T cells, induction of cytolytic effector cells, and B-cell costimulation for proliferation and lg production. We report that IL-15 at optimal concentrations rapidly induced memory (CD45RO+) CD4+ and CD8+ T cells and naive (CD45RO-) CD8+ T ...

An inorganic-organic hybrid fluorescence chemosensor (DA/SBA-15) was prepared by covalent immobilization of a dansylamide derivative into the channels of mesoporous silica material SBA-15 via (3-aminopropyl)triethoxysilane (APTES) groups. The primary hexagonally ordered mesoporous structure of SBA-15 was preserved after the grafting procedure. Fluorescence characterization shows that the obtain...

A bioassay-guided fractionation and chemical investigation of the trunk of Berberis koreana led to the isolation and identification of three new triterpenoids, 2 α,3 α,19 α-trihydroxy-urs-12-en-24-formyl-28-oic acid (1), 2 α,3 β,21 α-trihydroxy-urs-12-en-28-oic acid ( 2), and 3 β-acetyloxy-1-oxo-olean-12-en-28-oic acid (3), along with seven known triterpenoids (4-10). The structures of these ne...
