Synthesis, molecular modeling and SAR. study of novel pyrazolo[5,1-f] [1,6]naphthyridines as CB2 receptor antagonists/inverse agonists

Pyrazolo[5,1-f][1,6]naphthyridine-carboxamide derivatives were synthesized and evaluated for the affinity at CB1 and CB2 receptors. Based on the AgOTf and proline-cocatalyzed multicomponent methodology, the ethyl 5-(p-tolyl)pyrazolo[5,1-f][1,6]naphthyridine-2-carboxylate (12) and ethyl 5-(2,4-dichlorophenyl)pyrazolo[5,1-f][1,6]naphthyridine-2-carboxylate (13) intermediates were synthesized from the appropriate o-alkynylaldehydes, p-toluenesulfonyl hydrazide and ethyl pyruvate. Most of the novel compounds feature a p-tolyl (8a-i) or a 2,4-dichlorophenyl (8j) motif at the C-5-position of the tricyclic pyrazolo[5,1-f][1,6]naphthyridine scaffold. Structural variation on the carboxamide moiety at the C-2-position includes basic monocyclic, terpenoid and adamantine-based amines. Among these derivatives, compound 8h (N-adamant-1-yl-5-(p-tolyl)pyrazolo[5,1-f][1,6]naphthyridine-2-carboxamide) exhibited the highest CB2 receptor affinity (K-i= 33 nM) and a high degree of selectivity (KiCB1/KiCB2= 173:1), whereas a similar trend in the near nM range was seen for the bornyl analogue (compound 8f, K-i; = 53 nM) and the myrtanyl derivative 8j (K-i = 67 nM). Effects of 8h, 8f and 8j on forskolin-stimulated cAMP levels were determined, showing antagonist/inverse agonist properties for such compounds. Docking studies conducted for these derivatives and the reference antagonist/inverse agonist compound 4 (SR144528) disclosed the specific pattern of interactions probably related to the pyrazolo[5,1-f][1,6]naphthyridine scaffold as CB2 inverse agonists.

Development of a sensitive and selective fluorescent probe for Zn2+ based on naphthyridine Schiff base

In this study, bearing 4-methyl-7-acetamide-1,8-naphthyridyl group as the fluorophore and the receptor, we designed and synthesized a new-type Schiff-base ligand 1 which was identified as a Zn2+ fluorescent probe. The excellent selectivity and high sensitivity of this as-synthesized fluorescent probe 1 towards Zn2+ over other various biogenic metal ions were observed, for that only Zn2+ induced a drastic enhancement by about 63-fold in intensity of fluorescence emission at 504 nm, and the limit of detection (LOD) could reach 7.52 nM. Moreover, the formation of a 2:1 complex between this probe 1 and Zn2+ was determined, and the perfect invertibility and renewability of this probe 1 for sensing Zn2+ were also demonstrated. As a result, the practical applications of 1 were broadened for sensing and monitoring Zn2+ environmentally and biologically.

Catalytic activity in transfer hydrogenation using ruthenium (II) carbonyl complexes containing two 1,8-naphthyridine as N-monodentate ligands

A new series of novel complexes of type cis-[Ru(CO)(2)Cl-2(L)(2)], L = 2-phenyl-1,8-naphthyridine, 2-(4′-nitrophenyl)-1,8-naphthyridine, 2-(4′-bromophenyl)-1,8-naphthyridine, 2-(4′-methylphenyl)-1,8-naphthyridine, 2-(3′-methoxyphenyl)-1,8-naphthyridine, 2-(2′-methoxyphenyl)-1,8-naphthyridine and 2-(4′-methoxyphenyl)-1,8-naphthyridine have been successfully synthesized and characterized. We found that the complexes can be directly synthesized from [RuCl2(CO)(2)](2) with high yield. The crystallographic structures of complex cis-[RuCl2(CO)(2)(2-(4′-methoxyphenyl)-1,8-naphthyridine-kappa N8)(2)] and cis-[RuCl2(CO)(2)(2-(2′-methoxyphenyl)-1,8-naphthyridine-kappa N8)(2)] have been established by X-ray single crystal diffraction studies, which indicate an octahedral geometry with two 1,8-naphthyridine ligands coordinated to the metal in a N-monodentate fashion. The ruthenium(II) complexes have been studied as catalysts in the transfer hydrogenation of acetophenone. We found that complexes show moderate activities and a 100% selectivity. The best turnover frequency (390 h(-1)) is found for cis-[RuCl2(CO)(2)(2-(4′-methoxyphenyl)-1,8-naphthyridine-kappa N8)(2)] when the substrate/catalysis ratio was 1000/1. The catalytic conditions were optimized using different substrate/catalyst and base/catalyst ratios.

1,8-Naphthyridine and 8-hydroxyquinoline modified Rhodamine B derivatives: Turn-on fluorescent and colorimetric sensors for Al3+ and Cu2+

Based on Rhodamine B, two Al3+/Cu2+-selective chemosensors were synthesized, which display a high selectivity for Al3+ and Cu2+ among environmentally and biologically relevant metal ions. A 1,8-Naphthyridine modified rhodamine derivative can detect Al3+ in ethanol with off-on fluorescence behavior, and detect Cu2+ in aqueous solution with colorimetric method. The 8-Hydroxyquinoline-based rhodamine sensor can detect Al3+ in ethanol with both off-on fluorescence and colorimetric methods. The detection mechanism involves a ring-opening process as a consequence of metal complex formation. Job’s plots and a time-of-flight mass spectral study indicated that each chemosensor chelated Al3+/Cu2+ with 1:1 stoichiometry. The binding of the chemosensors and Al3+/Cu2+ is chemically reversible by the addition of F-/EDTA solution, respectively. (C) 2013 Elsevier Ltd. All rights reserved.

A novel OFF-ON-OFF fluorescence chemosensor for hypersensitive detection and bioimaging of Al(III) in living organisms and natural water environment

High-selectivity detection of trace Al3+ ions in water and biological systems by a fluorescence imaging method is not yet mature. Herein, we synthesized a novel reversible Al3+ -specific fluorescent probe named RBLF by linking Rhodamine B and pyridine-3-sulfonyl chloride through o-phenylenediamine in several reactions. RBLF exhibited an ultra-high sensitive and excellent selective response towards Al3+ by fluorescence and UV-vis spectra in aqueous solutions. What is more worth mentioning is that its response is fast, dual changes in color and fluorescence of the probe solution that can occur instantaneously after adding with Al3+. Its detection limit for Al3+ ions in aqueous system solutions is 14.23 nM, which is far below the maximum allowable amount of Al3+ in drinking water. Moreover, the probe provided an effective method for detecting low concentrations of Al3+ in natural water, living cells, zebrafish and plant tissues.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 61-19-8 help many people in the next few years. COA of Formula: C10H14N5O7P.
