SUMMARY Dimethyl sulfoxide is a convenient solvent of 7,12-dimethylbenz(a)anthracene and related polycycic aromatic hydrocarbons for i.v. injection. As judged by its ability to induce both adrenal necrosis and mammary tumors, this solu tion is at least as active as fatty emulsions of 7,12-dimethyl benz(a)anthracene now in general use. While the preparation of emulsions is timeconsuming andrequi...

291 The Effects of Ferrous Ion and Dithioerythritol on Inhibition by Hydroxyurea of Ribonucleotide Re ductase. 349 Influence of Estrogens and Endocrine Ablation on Duration of Remission Produced by Ovariectomy or Androgen Treatment of 7,12-Dimethylbenz[a@ anthra cene-induced Rat Mammary Tumors. 353 Inhibitory Effect of D-Glucosamine and Other Sugar Analogs on the Viability and Transplantability...

Literature survey reveal that a good number of Anthracene and substituted Anthracene are potential lasing organic compounds. As per mit suo meada66 9,10-dimethyl and 9,10-diphenyl Anthracenes exhibit lasing properties, around 435-450 nm (ethanol). In continuation of our studies in this lab, our objective is to synthesize new lasing organic dyes, in particular, new Anthracene derivatives and stu...

The title compound, C25H20N2, (I), was synthesized from the condensation reaction of anthracene-9-carbaldehyde and tryptamine in dry ethanol. The indole ring system (r.m.s. deviation = 0.016 Å) makes a dihedral angle of 63.56 (8)° with the anthracene ring (r.m.s. deviation = 0.023 Å). There is a short intra-molecular C-H⋯N inter-action present, and a C-H⋯π inter-action involving the two ring sy...

Radially oriented anthracene nanowires and their self-assembled concentric ring arrays were prepared through a facial solvent-evaporation method. The successful growth of anthracene nanowires can be attributed to a combined mechanism of molecular self-assembly facilitated by strong π-π intermolecular interactions together with evaporation-induced capillary flow and fingering instability. Their ...

Extended azaborine heterocycles are promising biomedical and electronic materials. Herein we report the synthesis of a novel family of azaborine anthracene derivatives and their structural, electrochemical and spectroscopic characterization. We observe that the properties of these materials are remarkably similar to the parent hydrocarbons, suggesting the innocence of the CC to BN bond substitu...

A line of C3H mouse embryo cells (C3H/10T1/2 clone 8) sensitive to postconfluence inhibition of cell division was used for a variety of quantitative and qualitative studies of chemical oncogenesis in culture. The polycyclic hydro carbons (PH), 3-methylcholanthrene, dibenz[a,h]anthracene, and 7,12-dimethylbenz[a]anthracene, caused varying degrees of cytotoxicity and produced morphologically and ...

In the title centrosymmetric compound, C(28)H(32)N(4)O(2) (2+) 2I(-), the two midazole rings are approximately perpendicular to the central anthracene ring system [dihedral angle = 86.6 (2)°]. The ionic units are linked into a two-dimensional network parallel to (01) by C-H⋯I hydrogen bonds and π-π inter-actions involving the anthracene ring system and imidazole rings [centroid-centroid distanc...

Hybrid functional theory is applied for calculation of band gaps in the molecular crystals anthracene, pentaerythritol (PE), pentaerythritol tetranitrate (PETN), and cyclotrimethylene trinitramine (RDX). The B3LYP hybrid functional is observed to produce band gap estimates in reasonable agreement with experiment for anthracene and RDX. This approach, which has been successfully used recently fo...
