254-60-4, Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 254-60-4, Name is 1,8-Diazanaphthalene

Translating a homogenous catalyst into a heterogeneous catalyst requires a fundamental understanding of how the catalyst ?fits? into the zeolite and how the reaction is influenced. Previous studies of bimetallic catalyst design identified a potent copper homobinuclear catalyst, [(L)Cu2(H)]+ for the selective decomposition of formic acid. Here, a close interplay between theory and experiment shows how to preserve this selective reactivity within zeolites. Gas-phase experiments and DFT calculations showed that switching from 1,1-bis(diphenylphosphino)-methane ligand to the 1,8-naphthyridine ligand produced an equally potent catalyst. DFT calculations show that this new catalyst neatly fits into a zeolite which does not perturb reactivity, thus providing a unique example on how ?heterogenization? of a homogenous catalyst for the selective catalysed extrusion of carbon dioxide from formic acid can be achieved, with important application in hydrogen storage and in situ generation of H2.

Drug-induced skin phototoxicity is a well recognised cause of abnormal skin photosensitivity. This chapter gives a general overview of the history, the range of drugs and the types of skin reactions associated with photoxicity. The fluoroquinolone antibiotics have become the most important group of pharmaceutical phototoxins of the last decade. The response of regulatory authorities to the finding that fluoroquinolones photosensitise skin carcinogenesis in mice has led to increased examination of phototoxic potential during drug development. The validation of simple in vitro screening methods and an increased knowledge of structure-phototoxic activity relationships may, in the future, lead to a reduced number of phototoxic drugs reaching the market.

Molecular architectures possessing the combination of heteroaromatic and saturated N-heterocycles are of great importance because of their higher solubility in the gastrointestinal tract due to weak crystal packing in the three-dimensional structure. Other biological activity like selectivity is also increased in a positive way. However, compared to fully aromatic fused heterocycles, synthesis of partially saturated fused heterocycles is much more difficult since the later needs greater control over the reaction conditions. In this context, 1,2,3,4-tetrahydronaphthyridines (THNADs) are essential part of pharmaceutically important natural products and drug molecules. However, the synthesis of THNAD is seldom reported in literature. To the best of our knowledge, this is the first report of metal-free one pot synthesis of 1,2,3,4-tetrahydro-1,6-naphthyridines without starting from any nitrogen heterocycles in water. Moreover, this study discloses the involvement of isocyanide in a chemical reaction whose net effect is only to reduce a C=C bond which is unusual in isocyanide literature.

A systematic study on the condensation reaction of 2,4-dichlorobenzo[. h]quinoline and naphth-1-ylamine in the presence of CuI as catalyst to functionalised mono- and di-substituted (naphthalen-1-yl)benzo[. h]quinoline amines was described. Subsequently these mono- and di-substituted amines on polyphosphoric acid catalysed cyclisation reaction with aromatic/heteroaromatic carboxylic acids led to the construction of angular and linear aromatic/heteroaromatic substituted dinaphthonaphthyridines in good yields.

Cannabis has long been known to limit or prevent nausea and vomiting, lack of appetite, and pain. For this reason, cannabinoids have been successfully used in the treatment of some of the unwanted side effects caused by cancer chemotherapy. Besides their palliative effects, research from the past two decades has demonstrated their promising potential as antitumor agents in a wide variety of tumors. Cannabinoids of endogenous, phytogenic, and synthetic nature have been shown to impact the proliferation of cancer through the modulation of different proteins involved in the endocannabinoid system such as the G protein?coupled receptors CB1, CB2, and GRP55, the ionotropic receptor TRPV1, or the fatty acid amide hydrolase (FAAH). In this article, we aim to structurally classify the antitumor cannabinoid chemotypes described so far according to their targets and types of cancer. In a drug discovery approach, their in silico pharmacokinetic profile has been evaluated in order to identify appropriate drug-like profiles, which should be taken into account for further progress toward the clinic. This analysis may provide structural insights into the selection of specific cannabinoid scaffolds for the development of antitumor drugs for the treatment of particular types of cancer.

Pressure-induced irreversible chemical reactions of naphthalene, 2,3-naphthyridine (2,3-Nap), and 1,5-naphthyridine (1,5-Nap) were observed after compression (>16?18 GPa) at room temperature. Regardless of the initial materials, amorphous products in which sp3 carbon was formed were obtained after the samples were recovered at ambient pressure. The X-ray photoelectron spectroscopy (XPS) of the product from naphthalene indicated that the carbon sp3/sp2 ratio was much lower than that of benzene nanothreads. Nitrogen remained in the amorphous products from 1,5-Nap and 2,3-Nap and bonded to both sp3 and sp2 carbons.
