Researchers are common within chemical engineering and are often tasked with creating and developing new chemical techniques, frequently combining other advanced and emerging scientific areas. 100-49-2, Name is Cyclohexanemethanol, SMILES is OCC1CCCCC1, belongs to naphthyridine compound. In a document, author is El-Naggar, Abeer M., introduce the new discover, HPLC of Formula: https://www.ambeed.com/products/100-49-2.html.

Background: One of the promising scaffolds in drug discovery is the fused pyrimidine derivatives. Objective and Method: Efficient synthesis of a novel series of 18 new 1,8-naphthyridine-3-carbonitrile, 2-amino pyrido[2,3-d] pyrimidine derivatives via multi-component reactions of aromatic aldehydes, active methylene, and an aromatic amine under microwave irradiation and evaluation of their anticancer activity and possible mechanisms. Results: Only compounds 5 (a-c)had a significant antiproliferative activity in hepatic HepG2 cells at submicromolar concentration (7.5-10 mu M). Similarly, only compound 11 (a-c) had a significant activity in breast MCF7 cells at (4-7 mu M). Derivatives with one methoxyphenyl substitution (5a and 11a) were not different from derivatives having dimethoxyphenyl substitution (5b and 11b). However, thiophene substitution (5c and 11c) enhanced the anticancer activity in both cells lines examined by 25% in HepG2 and by similar to 45% in MCF7 cells compared to a and b derivatives. All compounds were safe to both normal human lung cells (WI-38) and RBCs at concentrations up to 40 mM. The antiproliferative activity of compounds 5 (a-c) in HepG2 could be attributed to an induction of intrinsic apoptotic pathway as evidenced from the induction of initiator caspase 9 by similar to 4 folds. While, the activity of compounds 11 (a-c) could be attributed to their potential to inhibit tyrosine kinases (TK) by up to 85%. The IC50 of derivative 11c against TK was at 173 nM. Conclusion: The present study reported that derivatives 5 and 11 have merit for further investigation as anticancer and TK inhibitors.

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 100-49-2, in my other articles. HPLC of Formula: https://www.ambeed.com/products/100-49-2.html.

In a article, author is Li, Zhensheng, introduce new discover of the category.

Three boron fluorine complexes B1-B3 containing pyridine/1,8-naphthyridine were synthesized and structurally characterized. Compounds B1 and B2 exhibited strong fluorescence in solution and solid state. The solvent-dependent luminous properties and large Stokes shift in solution could be explained by intramolecular charge transfer, which is confirmed by time-dependent density functional theory calculation. The absolute quantum yield of B1 in powder form reached 0.48 because of inhibiting planar pi…pi stacking. Single-crystal X-ray diffraction analyses of B1 and B2 revealed that weak intermolecular C H…F and H…pi interactions hinder further stacking of pi…pi dimers, consequently preventing aggregation-induced quenching. Complex 113, composed of boron-dipyrromethene and 1,8-naphthyridine fluorophore, had potential applications as a pH ratiometric fluorescent sensor. (c) 2014 Elsevier Ltd. All rights reserved.

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.

The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing quantitative kinetic, spectroscopic, and theoretical assessments of solvent structures and their interactions with reaction intermediates. 94839-07-3, Name is Benzo[d][1,3]dioxol-5-ylboronic acid, SMILES is OB(C1=CC=C(OCO2)C2=C1)O, belongs to naphthyridine compound.

A selective receptor for sensing and discriminating of GMP is useful not only in the energy metabolism but also in the processes of DNA replication and transcription-related to GMP; such a receptor is presently rare especially in a pure water environment. Herein, a novel 1,8-naphthyridine-based tripodal imidazolium gripper-like molecular served as a turn-on fluorescent receptor (TINP) was designed and synthesized for selective sensing and discriminating GMP from structurally similar GNPs (N = D and T) and XMPs (X = U, T, A, and C) in 100% aqueous solution. TINP consists of 1,8-naphthyridines and imidazolium cations. 2-acetylamino-1,8-naphthyridine was chosen as fluorophore and tri-hydrogen bonds interactions sites for the nucleobase guanine. Imida-zolium cations were identified as the phosphate part receiving moieties and communicators, while the three imidazolium cations also served as indispensable water-soluble parts. GMP caused a remarkable fluorescence enhancement (ca. 6.5-fold) with a quantum yield (Phi(f)) of 0.26 at 399 nm, displaying an efficient turn on behavior. The sensing mechanisms and fluorescence response were explained by Job’s plot, NMR spectroscopic analysis, and theoretical calculations. The turn-on fluorescent property for GMP can be attributed to photoinduced electron transfer (PeT) transitions with some mixed intraligand charge-transfer (ILCT) transitions. Finally, the preliminary results of cell experiments show that the receptor can be applied for the imaging of GMP in living mammalian cells.

Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms. If you like, you can also browse other articles about this kind.

Two stereoisomers of cis-[Ru(bpy)(pynp)(CO)Cl]PF(6) (bpy = 2,2′-bipyridine, pynp 2-(2-pyridyl)-1,8-naphthyridine) were selectively prepared. The pyridyl rings of the pynp ligand in [Ru(bpy)(pynp)(CO) Cl](+) are situated trans and cis, respectively, to the CO ligand. The corresponding CH(3)CN complex ([Ru(bpy)(pynp)(CO) (CH(3)CN)](2+)) was also prepared by replacement reactions of the chlorido ligand in CH(3)CN. Using these complexes, ligand-centered redox behavior was studied by electrochemical and spectroelectrochemical techniques. The molecular structures of pynp-containing complexes (two stereoisomers of [Ru(bpy)(pynp) (CO)Cl]PF(6) and [Ru(pynp)(2)(CO)Cl]PF(6)) were determined by X-ray structure analyses.

In a patnet, author is Shaabani, Ahmad, once mentioned the new application about 13822-56-5.

The diversity-oriented synthesis of a naphthyridine scaffold has been demonstrated via a novel domino four-component reaction. The syntheses were achieved by reacting a diamine, 1,1-bis(methylthio)-2-nitroethylene, 2-aminoprop-1-ene-1,1,3-tricarbonitrile, and various carbonyl compounds using a deep eutectic solvent (DES), based on choline chloride/urea, thus providing a new class of poly-functionalized fused naphthyridine derivatives with the concomitant formation of three new rings and six sigma bonds. The reaction conditions were mild and did not require additional base catalysts. Given the inexpensive, nontoxic, and recyclable nature of the DES, these reaction conditions are simple and highly environmentally friendly. (C) 2015 Elsevier Ltd. All rights reserved.
