DNQ-PAC structure: 4-, 5- and 6- sulfonyl DNQ ester.

Hybrid Zeolitic Imidazolate Frameworks : Controlling Framework Porosity and Functionality by Mixed - Linker Synthesis

A positive-tone, aqueous base soluble, polynorbornene (PNB) dielectric formulation has been developed. The photolithographic solubility switching mechanism is based on diazonaphthoquinone (DNQ) inhibition of polynorbornene resin functionalized with pendent hexafluoroisopropanol and carboxylic acid substituents. The optical contrast (at 365 nm) was found to be 2.3. The maximum height-to-width as...

Chemistry and biology of deoxynyboquinone, a potent inducer of cancer cell death.

Deoxynyboquinone (DNQ) is a potent antineoplastic agent with an unknown mechanism of action. Here we describe a facile synthetic route to this anthraquinone, and we use this material to determine the mechanism by which DNQ induces death in cancer cells. DNQ was synthesized in seven linear steps through a route employing three palladium-mediated coupling reactions. Experiments performed on cance...

Crystal structure of methyl 4-(4-hy­droxy­phen­yl)-6-methyl-2-oxo-1,2,3,4-tetra­hydro­pyrimidine-5-carboxyl­ate monohydrate

The title hydrate, C13H14N2O4·H2O, crystallizes with two formula units in the asymmetric unit (Z' = 2). The dihedral angles between the planes of the tetra-hydro-pyrimidine ring and the 4-hy-droxy-phenyl ring and ester group are 86.78 (4) and 6.81 (6)°, respectively, for one mol-ecule and 89.35 (4) and 3.02 (4)° for the other. In the crystal, the organic mol-ecules form a dimer, linked by a pai...

Crystal structure of 5-(4-benzyl­oxyphen­yl)-3-(4-meth­oxy­phen­yl)-6-methyl­cyclo­hex-2-en-1-one

The title compound, C27H26O3, crystallized with two independent mol-ecules (A and B) in the asymmetric unit. In mol-ecule A, the plane of the central benzene ring forms dihedral angles of 75.78 (14) and 52.75 (16)° with that of the terminal benzene rings, and the dihedral angle between the planes of the terminal benzene rings is 51.49 (17)°. The corresponding values for mol-ecule B are 75.18 (1...
