New Advances in Chemical Research in 2021. In an article, author is Martin-Encinas, Endika, once mentioned the application of 1185-55-3, Name is Trimethoxy(methyl)silane, molecular formula is C4H12O3Si, molecular weight is 136.2218, category is naphthyridine.

The topoisomerase I enzymatic inhibition of hybrid quinolino [4,3-b] (Siegel et al., 2013; Antony et al., 2003) [1,5]naphthyridines and quinolino [4,3-b] (Siegel et al., 2013; Antony et al., 2003) [1,5]naphthyridin-6(5H)-ones was investigated. First, the synthesis of these fused compounds was performed by intramolecular [4 + 2]-cycloaddition reaction of functionalized aldimines obtained by the condensation of 3-aminopyridine and unsaturated aldehydes affording corresponding hybrid 5-tosylhexahydroquinolino [4,3-b] (Siegel et al., 2013; Antony et al., 2003) [1,5]naphthyridine and tetrahydroquinolino [4,3-b] (Siegel et al., 2013; Antony et al., 2003) [1,5]naphthyridin-6(5H)-one compounds with good to high general yields. Subsequent dehydrogenation led to the corresponding more unsaturated dihydro (Siegel et al., 2013; Antony et al., 2003) [1,5]naphthyridine and (Siegel et al., 2013; Antony et al., 2003) [1,5]naphthyridin-6(5H)-one derivatives in quantitative yields. The new polycyclic products show excellent-good activity as topoisomerase I (TopI) inhibitors that lead to Topl induced nicking of plasmids. This is consistent with the compounds acting as TopI poisons resulting in the accumulation of trapped cleavage complexes in the DNA. The cytotoxic effect on cell lines A549, SKOV3 and on non-cancerous MRCS was also screened. Tetrahydroquinolino [4,3-b] (Siegel et al., 2013; Antony et al., 2003) [1,5]naphthyridin-6(5H)-one 9 resulted the most cytotoxic compound with IC50 values of 3.25 +/- 0.91 mu M and 2.08 +/- 1.89 mu M against the A549 cell line and the SKOV3 cell line, respectively. Also, hexahydroquinolino [4,3-b] (Siegel et al., 2013; Antony et al., 2003) [1,5]naphthyridine 8a and dihydroquinolino [4,3-b] (Siegel et al., 2013; Antony et al., 2003) [1,5]naphthyridine 10a showed good cytotoxicity against these cell lines. None of the compounds presented cytotoxic effects against non-malignant pulmonary fibroblasts (MRC-5). (C) 2020 Elsevier Masson SAS. All rights reserved.

New Advances in Chemical Research, April 2021.The transformation of simple hydrocarbons into more complex and valuable products via catalytic C–H bond functionalisation has revolutionised modern synthetic chemistry. 1185-55-3, Name is Trimethoxy(methyl)silane, SMILES is C[Si](OC)(OC)OC, belongs to naphthyridine compound. In a document, author is Chen, Yong, introduce the new discover, Category: naphthyridines.

Tetranuclear copper(I) complexes containing N,N’-bis(5,7-dimethyl-1,8-naphthyridine-2-yl)amine and phosphine ligands with close intramolecular Cu(I)center dot center dot center dot Cu(I) contacts were found to precipitate as thermodynamically stable and crystalline quasi-2D sheet-like nanostructures. Kinetically stable, amorphous, spherical particles were also identified during the precipitation/crystallization processes of these copper(I) complexes in a dichloromethane/hexane mixture. The distinct phosphorescent properties of these two forms of nanostructures were studied and a crystallization-induced emission enhancement was observed during the morphological evolution from amorphous spherical particles to crystalline nanosheets. All of these photophysical properties were rationalized by density functional theory calculations.

The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis.Welcome to check out more blogs about 1185-55-3, in my other articles. Category: naphthyridines.

We have previously reported the discovery and initial SAR of the [1,7]naphthyridine-3-carbonitriles and quinoline-3-carbonitriles as Tumor Progression Loci-2 (Tp12) kinase inhibitors. In this paper, we report new SAR efforts which have led to the identification of 4-alkylamino-[1,7]naphthyridine-3-carbonitriles. These compounds show good in vitro and in vivo activity against Tp12 and improved pharmacokinetic properties. In addition they are highly selective for Tp12 kinase over other kinases, for example, EGFR, MEK, MK2, and p38. Lead compound 4-cycloheptylamino-6-[(pyridin-3-ylmethyl)-amino]-[1,7]naphthyridine-3-carbonit-rile (30) was efficacious in a rat model of LPS-induced TNF-alpha production. (C) 2007 Elsevier Ltd.
