Some examples of the diverse research done by chemistry experts include discovery of new medicines and vaccines, improving understanding of environmental issues, and development of new chemical products and materials. 1185-55-3, Name is Trimethoxy(methyl)silane, molecular formula is C4H12O3Si, Electric Literature of 1185-55-3, belongs to naphthyridine compound, is a common compound. In a patnet, author is Yang, Ming-Cong, once mentioned the new application about 1185-55-3.

Calamitic liquid crystalline organic semiconductors based on an electron-deficient dibenzo[c,h][2,6]naphthyridine (DBN) core were designed for electron transport materials and synthesized from 6-bromoisatin to form a key intermediate without tedious purification by means of a one-pot reaction including 4 steps, and then the target products were obtained in an additional 3 steps in a total yield of 13%. Two dialkylated DBN derivatives, 2,8-didecyl DBN (C10-DBN-C10) and 2,8-didodecyl DBN (C12-DBN-C12), exhibited a low ordered mesophase of smectic C (SmC) only. Their phase transitions, photophysical properties, and charge carrier transport properties were investigated and compared with their carbon analogs, i.e., chrysene and the DBN isomers of isoquino[8,7-h]isoquinoline derivatives. In the SmC phase, transient photocurrents had well-defined transits, which allowed us to evaluate their exact mobilities. The mobility for negative and positive carriers in the SmC phase depended on both electric field and temperature, which suggested that the conduction mechanism is via electronic hopping transport for both holes and electrons. It was unexpectedly found that C10-DBN-C10 in the SmC phase exhibited quite low mobility on the order of 10(-5) cm(2) V-1 s(-1), which is two orders of magnitude smaller than that for dialkylated chrysenes, and is comparable to the typical mobility in liquid crystalline semiconductors with large dipole moments, even though the DBN core has no dipole moment; this is also true for holes. This new phenomenon has not been reported before, and may provide new insight into how mobility in liquid-crystal phases is determined.

Fluoroquinolones are synthetic antibacterial agents that stabilize the ternary complex of prokaryotic topoisomerase II enzymes (gyrase and Topo IV), leading to extensive DNA fragmentation and bacteria death. Despite the similar structural folds within the critical regions of prokaryotic and eukaryotic topoisomerases, clinically relevant fluoroquinolones display a remarkable selectivity for prokaryotic topoisomerase II, with excellent safety records in humans. Typical agents that target human topoisomerases (such as etoposide, doxorubicin and mitoxantrone) are associated with significant toxicities and secondary malignancies, whereas clinically relevant fluoroquinolones are not known to exhibit such propensities. Although many fluoroquinolones have been shown to display topoisomerase-independent antiproliferative effects against various human cancer cells, those that are significantly active against eukaryotic topoisomerase show the same DNA damaging properties as other topoisomerase poisons. Empirical models also show that fluoroquinolones mediate some unique immunomodulatory activities of suppressing pro-inflammatory cytokines and super-inducing interleukin-2. This article reviews the extended roles of fluoroquinolones and their prospects as lead for the unmet needs of small and safe multimodal-targeting drug scaffolds.

The molecular geometries of four 2,4-dimethyl-7-amino-1,8-naphthyridine derivatives were optimized with B3LYP/6-31G(d) method. The energies of their frontier molecular orbitals and the molecular structures were investigated theoretically. The theoretical electronic spectra were calculated with TD-DFT in gas phase, PCM-TD-B3LYP/6-31+G(d) and semiempirical ZINDO in CH2Cl2 Solution. The influences of solvent model and calculation methods on the electronic absorption spectra were also probed. The calculated results show that delocalized pi bonds exist in the four 1 8-naphthyridine derivatives, and their energy gaps (Delta E) between HOMO and LUMO are relatively small. The variation in their Delta E values gives a consistent trend with that of their electronic absorption with lambda(max). Theoretical spectra achieved prove that their absorptions are red-shifted when the delocalization of pi electrons is enhanced or the capability to donate electron by a substituted group is increased. The maximum absorption peaks of the four derivatives originate from pi(HOMO)->pi* (LUMO) transition. The spectra calculated at the PCM-B3LYP/6-31+G(d) level have little difference from experimental results: the differences in wavelength are 2. 6, 10. 3, 5. 3 and 6. 9 nm, whereas those in energies are 0. 03, 0. 09, 0. 04 and 0. 08 eV, respectively. The obtained results suggest that electronic spectra calculated by TD-DFT on the bases of geometries optimized with B3LYP/6-31(d) are in agreement with experimental ones, and can account for the different spectroscopic properties of the four 1, 8-naphthyridine derivatives.

In targeted cancer therapy the search for novel molecules led to the discovery of a plethora of small organic molecules inhibiting cancer cell proliferation. Among these, quinazoline and derivatives, such as quinolines and naphthyridines, have been considered as of particular interest. One of these, the naphthyridine derivative 4-phenyl-2,7-di(piperazin-1-yl)-1,8-naphthyridine, has been analyzed in detail in the present work. We found that this compound elicited a powerful anti-proliferative activity on carcinoma cells, with IC50 values comparable with paradigmatic microtubule-deranging drugs. The mechanisms underlying this effect were seemingly due to a framework of cellular alterations that include peculiar alterations of mitochondria, i.e. an increase of mitochondrial membrane potential (MMP), followed by the typical MMP loss leading to the release of apoptogenic factors, and cell death by apoptosis. Furthermore, the analysis of cell cycle revealed that a significant percentage of treated cells was in G2/M phase. This block was seemingly due to a target effect of the naphthyridine derivative on microtubular network dynamic instability, which impaired mitotic spindle formation, possibly leading to mitotic catastrophy. Since the dual effects of naphthyridine derivative on cell cycle and mitotic spindle were obtained at very low concentrations, i.e. micromolar concentrations, we hypothesize that this compound could represent a new promising tool in the control of cancer cell proliferation.

We report that a polyhedral oligomeric silsesquioxane (POSS) core in a dendrimer can enhance the affinity of the molecular recognition via hydrogen bonds between 1,8-naphthyridine and guanosine nucleotides. The complexation of the naphthyridine ligands with a series of guanosine nucleotides was investigated, and it is shown that the POSS core should play a significant role in the stabilization of the complexes via hydrogen bonds. Finally, we demonstrate that the 1,8-naphthyridine ligand can selectively recognize guanosine triphosphate by assisting with the POSS-core dendrimer.

In a document, author is Paffen, Tim F. E., introduce the new discover, Reference of 1066-54-2.

A supramolecular system in which the concentration of a molecule is buffered over several orders of magnitude is presented. Molecular buffering is achieved as a result of competition in a ring-chain equilibrium of multivalent ureidopyrimidinone monomers and a monovalent naphthyridine molecule which acts as an end-capper. While we previously only considered divalent ureidopyrimidinone monomers we now present a model-driven engineering approach to improve molecular buffering using multivalent ring-chain systems. Our theoretical models reveal an odd-even effect where even-valent molecules show superior buffering capabilities. Furthermore, we predict that supramolecular buffering can be significantly improved using a tetravalent instead of a divalent molecule, since the tetravalent molecule can form two intramolecular rings with different stabilities due to statistical effects. Our model predictions are validated against experimental H-1 NMR data, demonstrating that model-driven engineering has considerable potential in supramolecular chemistry.
