Naphthyridine compounds are important, because they exhibit various biological activities including anticancer, antimicrobial, and anti-inflammatory activity. Some naphthyridines have antimitotic effects or demonstrate anticancer activity by inhibiting topoisomerase II. These compounds have been investigated as potential anticancer agents, and several compounds are now part of clinical trials. A series of naphthyridine derivatives were evaluated for their in vitro cytotoxic activities against human cervical cancer (HeLa), leukemia (HL-60), and prostate cancer (PC-3) cell lines using an MTT assay. Some compounds (14, 15, and 16) were more potent than colchicine against all three human cancer cell lines and compound (16) demonstrated potency with IC50 values of 0.7, 0.1, and 5.1 mu M, respectively. Comparative molecular field analysis (CoMFA) and comparative molecular similarity indices analysis (CoMSIA) were used for quantitative structure-activity relationship (QSAR) molecular modeling of these compounds. We obtained accurate and predictive three-dimensional QSAR (3D-QSAR) models as indicated by the high PLS parameters of the HeLa (q(2), 0.857; r(2), 0.984; r(pred)(2), 0.966), HL-60 (q(2), 0.777; r(2), 0.937; r(pred)(2), 0.913), and PC-3 (q(2), 0.702; r(2), 0.983; r(pred)(2), 0.974) cell lines. The 3D-QSAR contour maps suggested that the C-1 NH and C-4 carbonyl group of the naphthyridine ring and the C-2 naphthyl ring were important for cytotoxicity in all three human cancer cell lines.

Several studies demonstrated that cannabinoids reduce tumor growth, inhibit angiogenesis, and decrease cancer cell migration. As these molecules are well tolerated, it would be interesting to investigate the potential benefit of newly synthesized compounds, binding cannabinoid receptors (CBRs). In this study, we describe the synthesis and biological effect of 2-oxo-1,8-naphthyridine-3-carboxamide derivative LV50, a new compound with high CB2 receptor (CB2R) affinity. We demonstrated that it decreases viability of Jurkat leukemia cells, evaluated by Trypan Blue and 3-(4,5dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT), but mainly induces a proapoptotic effect. We observed an increase of a hypodiploid peak by propidium iodide staining and changes in nuclear morphology by Hoechst 33258. These data were confirmed by a significant increase of Annexin V staining, cleavage of the nuclear enzyme poly(ADP-ribose)-polymerase (PARP), and caspases activation. In addition, in order to exclude that LV50 non-specifically triggers death of all normal leukocytes, we tested the new compound on normal peripheral blood lymphocytes, excluding the idea of general cytotoxicity. To characterize the involvement of CB2R in the anti-proliferative and proapoptotic effect of LV50, cells were pretreated with a specific CB2R antagonist and the obtained data showed reverse results. Thus, we suggest a link between inhibition of cell survival and proapoptotic activity of the new compound that elicits this effect as selective CB2R agonist.

Future efforts will undeniably focus on the diversification of the new catalytic transformations. In my other articles, you can also check out more blogs about 94839-07-3. Quality Control of Benzo[d][1,3]dioxol-5-ylboronic acid.

The bacterial ribosomal decoding region of the aminoacyl-tRNA site (A-site) is one of the most validated target RNAs for antibiotic agents. Although natural aminoglycosides are well-characterized A-site binding ligands, high off-target effects and the growing emergence of bacterial resistance against aminoglycosides limit their clinical use. To circumvent these concerns with the aminoglycoside family, non-aminoglycoside A-site binding ligands have great potential as novel antibiotics against bacterial infections. This work describes a new class of small heterocyclic ligands based on the 2-amino-5,6,7-trimethyl-1,8-naphthyridine (ATMND) structure for the bacterial (Escherichia coli) A-site. ATMND possessing an aminoethyl side chain is found to strongly and selectively bind to the internal loop of the A-site (K-d=0.44m; pH7.0, I=0.06m, 5 degrees C). Significantly, this ligand shows the tightest binding reported to date among non-aminoglycoside ligands. The binding study based on the thermodynamics and molecular modelling reveals key molecular interactions of ATMND-C-2-NH2 for high affinity to the A-site. This ligand is also demonstrated to be applicable to the fluorescence indicator displacement assay for assessing ligand/A-site interactions.

The potential utility of systematic synthetic strategy will be applicable to efficient generations of chemical libraries of compounds to find ‘hit’ molecules. I hope my blog about 94839-07-3 is helpful to your research. COA of Formula: https://www.ambeed.com/products/94839-07-3.html.

Bacillus sp. are well-known biocontrol agents against various fungal plant pathogens. The present work was conducted for characterization of antagonistic Bacillus sp., isolated from tomato rhizosphere, and its control mechanisms against Fusarium oxysporum f. sp. lycopersici. A collection of 49 Bacillus isolates was obtained from the rhizosphere of tomato plants from infested field. Dual culture antagonism assay was carried out to assess the potential role of the strains against the pathogen. The evaluation of the strains was done for their antifungal ability and plant growth promoting properties including beta-1,3-glucanase, protease, chitinase, ammonia, siderophore, hydrogen cyanide, IAA and biofilm formation. Strain B44, identified as Bacillus sp. based on ribotyping (Accession no. MG779639), which exhibited maximum number of antifungal properties tested, was selected for further study. The strain was capable of producing hydrolytic enzymes such as beta-1,3-glucanase (15.61 U ml(-1) min(-1)), protease (1608.15 U ml(-1) min(-1)), and chitinase (129 U ml(-1) min(-1)), volatiles and non-volatile metabolites. Volatiles were extracted by solid phase micro extraction (SPME) technique. The major compounds identified by GC-MS analysis were 1,2-benzenedicarboxylic acid (23.99%), 6-undecylamine (6.61%), 2-methyloctacosane (5.91%), 9-octadecenoic acid (5.13%) and 1-tetradecanamine, N,N-dimethyl (5.05%). The prominent compounds identified by UPLC-MS were tert-butyl difluorophosphine (31.45%), 5-(4,4,5,5-tetramethyl-1, 3, 2-dioxaborolan-2-yl)-3,6-dihydro-2H-pyran (14.76%), 6-bromo-4-tert-butyl-1,1-dimethyl-1,2-dihydronaphthalene (8.35%), 2-amino-N-butyl-1,8-naphthyridine-3-carboxamide (6%), N,N-diethyl-2-[(ethylamino)methyl]-3-phenyloxirane-2-sulfonamide (5.12%). The isolate showed approx. 36% reduction in disease incidence in tomato plant under green house conditions and could serve as an efficient agent for biocontrol of wilt disease in tomato.

Defective metal string complex with one nickel(II) metal absent in center [Ni-8(mu(8)-N-9-2pz)(4)Cl-2](PF6)(2) (2) was obtained on the basis a pyrazine and naphthyridine-containing triamino ligand N-2-(pyrazin-2-yl)-N-7-(7-(pyrazin-2-ylamino)-1, 8-naphthyridin-2-yl)-1, 8-naphthyridine-2, 7-diamine (H3N9-2pz) (1). The small J value (J = -2.96 cm(-1)) suggests quite a weak magnetic interaction throughout the molecule of complex 2. The weak magnetic interaction in defective complex indicates that the spin exchange in metal string occurs through the metal core rather than the bridging ligands.

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.

A linear quantitative structure activity relationship (QSAR) model is presented for modeling and predicting the inhibition of HIV-1 integrase. The model was produced by using the stepwise multiple linear regression technique on a database that consists of 67 recently discovered 1,3,4-oxadiazole substituted naphthyridine derivatives. The developed QSAR model was evaluated for statistical significance and predictive power. The key conclusion of this study is that valence connectivity index order 1, lowest unoccupied molecular orbital and dielectric energy significantly affect the inhibition of HIV-1 integrase activity by 1,3,4-oxadiazole substituted naphthyridine derivatives. The selected physicochemical descriptors serve as a first guideline for the design of novel and potent antagonists of HIV-1 integrase. (C) 2010 Elsevier Masson SAS. All rights reserved.
