Temozolomide (TMZ) is a new cytotoxic triazene compound of clinical interest that is able to generate methyl adducts at the O(6)-guanine of DNA, which can be repaired by O(6)-alkylguanine-DNA alkyltransferase (OGAT). It was previously found that triazene compounds are highly immunosuppressive in mice. In the present study, we investigate whether TMZ could affect immune functions of human compet...

a facile and highly efficient method have been developed for the preconcentration of the mercury content in crude oil and gasoline samples after digestion with microwave-assisted digestion. octadecyl silica membrane disk has been modified by the recently synthesized triazene ligand, (e)-1-(2-ethoxyphenyl)-3-(4-nitrophenyl) triaz-1-ene (ent), then the modified membrane was used for the preconcen...

More than 40 years ago, we discovered that novel transplantation antigens can be induced in vivo or in vitro by treating murine leukemia with dacarbazine. Years later, this phenomenon that we called "Chemical Xenogenization" (CX) and more recently, "Drug-Induced Xenogenization" (DIX), was reproduced by Thierry Boon with a mutagenic/carcinogenic compound (i.e. N-methyl-N'-nitro-N-nitrosoguanidin...

The crystal structure of the title compound, (C(6)F(5))(2)N(3)H, is stabilized by N-H⋯N hydrogen bonding, forming centrosymmetric dimers organized in a herringbone motif. Important geometrical parameters are N-N = 1.272 (2) and 1.330 (2) Å and N-N-N = 112.56 (15)°. The dihedral angle between C(6)F(5) groups is 21.22 (9)°. The room temperature structure was reported by Leman et al. (1993). Inorg...

In the title compound, [Cd(C(14)H(14)N(3)O(2))(2)(CH(3)OH)(2)], each cadmium(II) center is six-coordinated by an N atom and an O atom of two 1,3-bis-(2-methoxy-phen-yl)triazene ligands and by the O atoms of two methanol mol-ecules. The distorted octa-hedral coordination geometry of the Cd atom has two N and two O atoms in the equatorial plane, and two O atoms in axial positions. The complex is ...

This work presents the recovery of biosorption supports as an alternative source of benign production of heterogeneous catalysts for oxidation reactions in mild conditions. Cr-containing FAU zeolite, in sodium form (NaY) and in proton form (HY), was recovered from biosorption studies and reused as support for the preparation of heterogeneous catalysts by the flexible ligand method, using 1,3-di...
