The new pyrrolo[3,4-c]pyridines and 2,7-naphthyridine derivatives have been synthesized. 4-Hydroxy-8-methyl-l-oxo-6-phenyl-1,2-dihydro-2,7-naphthyridine-3-carboxylic acid hydrazide (4) was the key intermediate for the synthesis of the novel derivatives of various chemical structures: Schiff bases, 1,3,4-oxadiazoles, pyrazoles, carbohydrazides, semi- and thiosemicarbazides. The structures of these new compounds were confirmed by elemental analysis and IR, NMR and MS spectra. The antitumor activities of the obtained derivatives were examined. Eight of the twenty one newly synthesized compounds were qualified by the NCI (Bethesda, MD, USA) for in vitro screening against 60 different human tumor cell lines. The most active proved to be the Schiff bases.

We describe the synthesis of eight novel putative mono- and bis-DNA intercalators from a common precursor, 6-bromoindolo[1,2-b][2,7]naphthyridine-5,12-dione. Of these new indoloquinones, our data indicate that two are most likely DNA mono-intercalators, but weaker than ethidium bromide, and two others are DNA bis-intercalators. Our indoloquinones are inactive against mammalian topoisomerase II. [GRAPHICS] .

Acetic anhydride behaves as a traceless activating agent allowing thermal intramolecular condensation of 2-(benzimidazol-1-ylmethyl) benzoic and nicotinic acids. Autoxidation gives benzimidazo[1,2-b]isoquinoline-6,11-diones (intermediates characterized) and benzimidazo[2,1-g]-1,7-naphthyridine-5,12-diones in a facile, one-pot transformation. The 1,4-dimethoxy analogue of the former is converted into benzimidazo[1,2-b]isoquinoline-1,4,6,11-tetrone using cerium ammonium nitrate (CAN). The 1,7-naphthyridine-5,12-dione system readily ring-opens, and an X-ray crystal structure of the methanol adduct was obtained.

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. 1631-25-0, Name is N-Cyclohexylmaleimide, SMILES is O=C(C=C1)N(C2CCCCC2)C1=O, belongs to naphthyridine compound. In a document, author is Yu, Shasha, introduce the new discover, Recommanded Product: N-Cyclohexylmaleimide.

Zirconocene-mediated multicomponent reactions of 1,3-butadiynes with ylidenemalononitriles in the absence or presence of CuCl have been developed. In the absence of CuCl, 1,3-butadiyne couples with three molecules of ylidenemalononitriles to yield azazirconacycles bearing a hexahydro-1,8-naphthyridine skeleton with high stereoselectivity. In the presence of CuCl, cyclopenta[b]pyridine or cyclopenta[b] quinolin-1-one derivatives are obtained via transmetalation of Zr-C bond to Cu-C bond as the key reaction step. These domino-type reactions proceed with high chemo-, regio- and/or stereoselectivities, and allowing the formation of multiple C-N and C-C bonds in a single operation.

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 1631-25-0. Recommanded Product: N-Cyclohexylmaleimide.

Structurally diverse inhibitors of the protein kinase CK2 are required for regulation of this ubiquitous protein to establish biological roles of the enzyme which catalyzes the phosphorylation of a vast number of substrate proteins. In this article we disclose a series of new bisubstrate inhibitors of CK2 that are structurally represented by the oligo(L-Asp) peptide conjugates of benzo[c][2,6]naphthyridine-8-carboxylic acid. This fragment originated from CX-4945, the first in class inhibitor taken to clinical trials. The most potent conjugates possessed two-digit picomolar affinity and clear selectivity for CK2 alpha in a panel of 140 protein kinases. Labeling of the inhibitors with a fluorescent dye yielded probes for a fluorescence anisotropy-based binding/displacement assay which can be used for analysis of CK2 and precise determination of affinity of the highly potent (tight-binding) CK2-targeting inhibitors.

In an article, author is Mahalakshmi, G., once mentioned the application of 63503-60-6, Name is 3-Chlorophenylboronic acid. Now introduce a scientific discovery about this category, Reference of 63503-60-6.

Two new 10-methoxydibenzo[b,h][1,6]naphthyridine-2-carboxamide derivatives (R1 and R2) have been synthesized and characterized using different spectral techniques. The binding of these probes with DNA was investigated using spectral (Electronic, fluorescence, H-1 NMR and circular dichroism) and molecular docking studies. These probes exhibited a strong fluorescence around 440 nm upon excitation around 380 nm. Electronic and competitive fluorescence titration studies, in HEPES [(4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid)] buffer/dimethyl sulfoxide (pH 7.4) medium, suggest that these probes bind strongly to DNA, which is substantiated by H-1 NMR study. The binding constants are calculated to be 5.3 x 10(7) and 6.8 x 10(6) M–(1) for R1 and R2, respectively. From the results of spectral studies, it is proposed that the mechanism of binding of these probes with DNA is through minor groove binding mode, which is further confirmed by circular dichroism and molecular docking studies. Initial cell viability screening using MTT (3-[4,5-methylthiazol-2-yl]-2,5-diphenyl-tetrazolium bromide) assay shows that normal Vero cells are viable towards these probes at nano molar concentration, which is the concentration range employed in the present study for DNA staining (IC50 in the order of 0.023 mM). The enhancement in fluorescence intensity of these probes upon binding with DNA enables the staining of DNA in agarose gel in gel electrophoresis experiment. The sensitivity of these probes is comparable with that of ethidium bromide and DNA amounts as low as 4 nano gram are detectable. Communicated by Ramaswamy H. Sarma
