Label-free and highly sensitive fluorescence detection of lead(ii) based on DNAzyme and exonuclease III-assisted cascade signal amplification

Routine detection of trace amounts of Pb2+ is of significant importance because it poses severe risks to human health and the environment. In this paper, a novel label-free fluorescence platform for the sensitive detection of Pb2+ has been successfully constructed by using Pb2+-specific 8-17 DNAzyme as the molecular recognition element, 2-amino-5,6,7-trimethyl-1,8-naphthyridine (ATMND) as the signal reporter, and exonuclease III (Exo III) as the signal amplifier. A good linearity between the fluorescence intensity and the logarithm of Pb2+ concentration was obtained in the range from 100 pM to 10 M with a correlation coefficient (R-2) of 0.99. The sensing system exhibited ultrasensitivity towards Pb2+ at low concentration (50 pM) without any labeling, modification, immobilization, or washing procedure. Besides, the proposed method was also highly selective for Pb2+ against other metal ions. This biosensor was robust and can be applied for the determination of Pb2+ in complex samples with desired recovery and good accuracy. With the successful demonstration of Pb2+ detection, the label-free biosensor can be readily expanded to monitor other targets in a simple, cost-effective, and ultrasensitive way by replacing the target-specific molecular recognition elements.

Novel annulated products from aminonaphthyridinones

2-(4-Methoxyphenyl)-1-oxo-1,2-dihydro-1,6-naphthyridine-4-carboxamide (4c) underwent Hofmann rearrangement with iodobenzene diacetate in methanol to give the corresponding 4-amino compound (6c). This, when reacted with 2,4-pentanedione and then hot phosphoryl chloride (attempted Combes synthesis) gave a new heterocyclic system, 6-(4-methoxyphenyl)-2-methylpyrido[3,2-c]pyrrolo[2,3-e]azocin-7(6H)-one (9c). This showed typical pyrrole-type reactivity at the 3-position. Alternatively, an attempt to convert the 4-NH2 in 6c to 4-OH by diazotization gave, instead, a [1,2,3]triazolo[1,5-a]pyridine-3-carboxaldehyde (16c). The same series of reactions on a benzo analog, 2-methyl-1-oxo-1,2-dihydrobenzo[b][1,6]naphthyridine-4-carboxamide (4a), gave the same results. (c) 2005 Elsevier Ltd. All rights reserved.

Palladium complexes with an annellated mesoionic carbene (MIC) ligand: catalytic sequential Sonogashira coupling/cyclization reaction for one-pot synthesis of benzofuran, indole, isocoumarin and isoquinolone derivatives

Two Pd(II) complexes (1 and 2) featuring a fused pi-conjugated imidazo[1,2-a][1,8]naphthyridine-based mesoionic carbene ligand have been synthesized and structurally characterized. Both complexes effectively catalyze the one-pot synthesis of benzofuran starting from phenylacetylene and 2-iodophenol under mild conditions. Complex 1 is found to be an excellent catalyst for the straightforward access to a library of benzofuran, indole, isocoumarin and isoquinolone derivatives by the reaction of terminal alkynes with 2-iodo derivates of phenol, N-methyl aniline, benzoic acid and N-methyl benzamide, respectively. The general utility of the catalytic method is demonstrated using a variety of diversely substituted terminal alkynes and the corresponding desired products are obtained in good to excellent yields. On the basis of control experiments, a two-cycle mechanism is proposed which involves the Sonogashira coupling of 2-iodo derivatives with alkynes and the subsequent cyclization of the corresponding 2-alkynyl compounds.

Application of 100-49-2, Because enzymes can increase reaction rates by enormous factors and tend to be very specific, typically producing only a single product in quantitative yield, they are the focus of active research.you can also check out more blogs about 100-49-2.

The preclinical discovery of vosaroxin for the treatment of acute myeloid leukemia

Introduction: Acute myeloid leukemia (AML) represents a disease with a very poor outcome and remains an area of significant unmet need necessitating novel therapeutic strategies. Among novel therapeutic agents, vosaroxin is a first-in-class anticancer quinolone derivative that targets topoisomerase II and induces site-selective double-strand breaks in DNA, leading to tumor cell apoptosis. Areas covered: Herein, the authors provide a comprehensive review of the preclinical development of vosaroxin. This includes coverage of vosaroxin’s mechanism of action in addition to its pharmacology and of the main studies reported over the past few years with vosaroxin when used to treat adult AML. Expert opinion: Given that vosaroxin is associated with fewer potential side effects, it may be of benefit to elderly patients with relapsed/refractory AML and to those with additional comorbidities who have previously received an anthracycline and cytarabine combination. Furthermore, vosaroxin also was seen to be active in multidrug-resistant preclinical models. However, further studies have to be performed to better evaluate its place in the armamentarium against AML.

Lophocladines, bioactive alkaloids from the red alga Lophocladia sp.

Lophocladines A (1) and B (2), two 2,7-naphthyridine alkaloids, were isolated from the marine red alga Lophocladia sp. collected in the Fijian Islands. Their structures were deduced on the basis of high-resolution mass spectra and one- and two-dimensional NMR spectroscopy. Lophocladine A (1) displayed affinity for NMDA receptors and was found to be a delta-opioid receptor antagonist, whereas lophocladine B (2) exhibited cytotoxicity to NCI-H460 human lung tumor and MDA-MB-435 breast cancer cell lines. Immunofluorescence studies indicated that the cytotoxicity of lophocladine B (2) was correlated with microtubule inhibition. This is the first reported occurrence of alkaloids based on a 2,7-naphthyridine skeleton from red algae.

On the basis of the very interesting pharmacological properties shown by the 5-amino[1,2,4]triazolo[4,3-a][1,8]naphthyridine-6-carboxamide derivatives 1, previously described by us, we have now prepared the 5-aminoimidazo[1,2-a][1,8]naphthyridine-6-carboxamide derivatives 2a-o (a new structural class) whose tricyclic system is isosteric to that of compounds 1. Both compounds 2 and some new properly substituted compounds 1 (1f-k) now synthesized were tested in vivo for their analgesic and anti-inflammatory activities: on the whole, compounds 2 showed notable analgesic properties, whereas many compounds 1 exhibited a very potent anti-inflammatory activity, coupled to scarce analgesic activity. All the effective compounds proved to be completely devoid of acute gastrolesivity (gastric damage) in rats (at the 200 mg kg(-1) oral dose). (C) 2009 Elsevier Masson SAS. All rights reserved.

gamma-Fe2O3@Cu3Al-LDH-N-amidinoglycine: a new amphoteric and reusable magnetic nanocatalyst for the synthesis of new pyrimidonaphthyridine derivatives and their antioxidant and antifungal activity evaluation

The synthesis of a novel layered double hydroxide (LDH)-based N-amidinoglycine-functionalized magnetic nanocomposite, gamma-Fe2O3@Cu3Al-LDH-N-amidinoglycine, has been described. The structure of the synthesized nanoparticles was characterized by different physicochemical techniques such as X-ray diffraction (XRD), thermogravimetric analysis (TGA), Fourier transform infrared spectroscopy (FT-IR), energy dispersive X-ray spectroscopy (EDX), and scanning electron microscopy (SEM), and using a vibrating sample magnetometer (VSM). These newly developed magnetic nanoparticles have been explored as a magnetically separable amphoteric nanocatalyst for the synthesis of new pyrimido[4,5-b][1,8] naphthyridine-7-carbonitrile derivatives in excellent yields via one-pot three-component reaction between aldehydes, 3-cyano-6-hydroxy-4-methyl-pyridin-2(1H)-one, and N,N-dimethyl-6-aminouracil. In the subsequent part of the present research, these synthesized pyrimido[4,5-b][1,8]naphthyridines were evaluated for their antioxidant and antifungal activities in vitro by using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) method and PDA (potato dextrose agar) medium, respectively.
