We successfully radiolabelled a novel prospective cannabinoid type 2 receptor ligand with F-18 and tested its biodistribution in animal models by positron emission tomography (PET)/computed tomography (CT) imaging. The radiolabelling process was conducted on an alkyl mesylate fragment of the main naphthyridine core, using highly efficient microfluidic technology. No preliminary protection was needed, and the product was purified by semi-prep HPLC and SPE formulation, allowing the desired diastereomeric mixture to be obtained in 29% radiochemical yield and >95% radiochemically pure. SOD1(G93A) mice were used as model of overexpression of CB2 receptors; PET imaging revealed a significant increase of the tracer distribution volume in the brain of symptomatic subjects compared with the asymptomatic ones.

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.

Two types of dicarbonykuthenium(II) complexes bearing the unsymmetrical bidentate ligand 2-(2-pyridy1)-1,8-naphthyridine were prepared. The complexes undergo irreversible ligand-localized one-electron reduction to form redox-induced metal-lacyclization between the bidentate naphthyridyl ligand and the terminal CO ligand located nearby. Chemical reductions using NaBH4 were also performed to isolate the reaction products; the formation of both a metal hydride (Ru-H) and an organo hydride (C-H) species was confirmed.

In this study, we developed a donor-pi-acceptor-pi-donor-type thermally activated delayed fluorescence (TADF) emitter (NyDPAc) using 1,5-naphthyridine as a core moiety. NyDPAc exhibited a high horizontal dipole ratio and thus a high external quantum efficiency (20.9%) even at a relatively low photoluminescence quantum yield (57%). 1,5-naphthyridine as an electron acceptor represents a promising core moiety for efficient TADF materials.

The continuous need for the development of new small molecule anti-cancer drugs calls for easily accessible sensor systems for measuring the effect of vast numbers of new drugs on their potential cellular targets. Here we demonstrate the use of an optical DNA biosensor to unravel the inhibitory mechanism of a member of a new family of small molecule human topoisomerase I inhibitors, the so-called indeno-1,5-naphthyridines. By analysing human topoisomerase I catalysis on the biosensor in the absence or presence of added drug complemented with a few traditional assays, we demonstrate that the investigated member of the indeno-1,5-naphthyridine family inhibited human topoisomerase I activity by blocking enzyme-DNA dissociation. To our knowledge, this represents the first characterized example of a small molecule drug that inhibits a post-ligation step of catalysis. The elucidation of a completely new and rather surprising drug mechanism-of-action using an optical real time sensor highlights the value of this assay system in the search for new topoisomerase I targeting small molecule drugs.

The dynamic chemical diversity of the numerous elements, ions and molecules that constitute the basis of life provides wide challenges and opportunities for research. In my other articles, you can also check out more blogs about 96-49-1. Recommanded Product: Ethylene carbonate.

The 2-Aminonicotinonitrile derivative was reacted with different bi-functional reagents such as formamide, thiourea, acetic anhydride, and phthalic anhydride under optimized conditions to give pyrimidine, thiourea, acetamide, and isoindoline derivatives, respectively, When it was treated with active methylene reagents as malononitrile, phenacyl bromide, and ethyl bromoacetate under varied experimental modulation, it afforded 1, 8-naphthyridine, ethyl, and methylamino nicotinonitrile derivatives, respectively. Also, it was reacted with p-toluene sulfonyl chloride, chloroacetyl chloride, and benzoyl chloride to give sulfonamide, 2-chloro-N-acetamide, and benzamide derivatives, respectively. Likewise, it was reacted with diethyl malonate, ethyl cyanoacetate, and cyano acetic acid to give ethylpropanoate, naphthyridine, and cyano acetamide derivatives, respectively. However, treatment of ethylpropanoate and cyano acetamide derivatives with hydrazine hydrate gave pyrazole and 5-amino-pyrazole nicotinonitrile derivatives, respectively. In addition, it was reacted with p-anisaldehyde, phenyl isocyanate, and triethyl orthoformate to give benzylamino nicotinonitrile, phenyl urea, and N-formamide derivatives, respectively. Furthermore, it was reacted with nitrous acid then coupled with aniline; it was also reacted with isatine and 1,3- dibromo propane to give oxoindoline derivative, and the dimer. Elemental analyses, together with spectroscopic data including IR, H-1-NMR in addition to C-13-NMR and mass spectra submit proofs for the chemical structures for all compounds. [GRAPHICS]
