Most N,N-disubstituted 5-amino-N,N-diethyl-9-isopropyl [1,2,4]triazolo[4,3-alpha] [1,8]naphthyridine-6-carboxamides 9 (compounds 9a, c-i) and the N-monosubstituted one 8c were obtained by treating with excess amine the corresponding 5-chloroderivative 7a, which was in turn prepared by cyclocondensation of the 2,4-dichloro-N,N-diethyl-1,8-naphthyridine-3-carboxamide (4a) with isobutyrohydrazide. Compounds 8a,b and 9b,j-m were obtained according with the methods shown in Scheme 1. The above now synthesized compounds, along with the previously described 8d and 8e, were tested for their anti-inflammatory, analgesic and antipyretic properties, and most compounds also for their effect on spontaneous mice locomotor activity and their acute gastrolesivity in rats. Several compounds showed potent anti-inflammatory and/or analgesic activities, and all the compounds tested proved to be completely lacking in acute gastrolesivity. In many cases compounds 8 and 9 produced hypothermic effect, usually at high doses. On the whole, the N-monosubstituted 5-aminoderivatives 8 appeared to be more potent anti-inflammatory agents than the corresponding N,N-disubstituted 9, whereas these latter compounds exhibited higher analgesic activity.

In an article, author is Lin, Zhihao, once mentioned the application of 13922-41-3, Name is Naphthalen-1-ylboronic acid. Now introduce a scientific discovery about this category, Safety of Naphthalen-1-ylboronic acid.

Cocrystallization of the aromatic bronsted bases with a series of mineral acids gave a total of ten hybrid salts with the compositions: (2-methylquinoline)2: (hydrochloride acid): 3H(2)O [(HL1)(+)center dot(L1)..(Cl-)center dot(H2O)(3)] (1), (6-bromobenzo[d]thiazol-2-amine): (hydrochloride acid) [(HL2)(+)center dot(Cl-)] (2), (6-bromobenzo[d]thiazol-2amine): (nitric acid) [(HL2)(+)center dot(NO3-)] (3), (6-bromobenzo[d]thiazol-2-amine): (sulfuric acid) [(HL2)(+)center dot (HSO4)(-)] (4), (6-bromobenzo[d]thiazol-2-amine): (phosphoric acid) [(HL2)(+)center dot(H2PO4)(-)] (5), (5,7-dimethy11,8-naphthyridine-2-amine): (hydrochloride acid): 3H(2)O[(HL3)(+)center dot(Cl-) (H2O)(3)] (6), (5,7-dimethyl-1,8naphthyridine-2-amine): (hydrobromic acid): CH3OH [(HL3)(+)center dot(Br)(-)center dot CH3OH] (7), (5,7-dimethyl-1,8naphthyridine-2-amine): (sulfuric acid): H2O [(HL3)(+)center dot(HSO4)(-)center dot H2O] (8), (2-aminophenol): (phosphoric acid) [(HLA)(+)center dot(H2PO4)(-)] (9), and (2-amino-4-chlorophenol): (phosphoric acid) [(HL5)(+)center dot(H2PO4)(-)] (10). The ten salts have been characterized by X-ray diffraction analysis, IR, and elemental analysis, and the melting points of all the salts were also reported. And their structural and supramolecular aspects are fully analyzed. The result reveals that among the ten investigated crystals the ring N of the heterocycle or the NH2 in the aminophenol are protonated when the acids are deprotonated, and the crystal packing is interpreted in terms of the strong charge-assisted classical hydrogen bonds between the NH+/NH3+ and deprotonated acidic groups. Further analysis of the crystal packing of the salts indicated that a different family of additional CH-O, CH-Cl, CH3-N, CH3-O, CH-Br, CH3-Br, Br-CI, Cl-S, O-S, O-O, Br-S, H-H, and pi-pi associations contribute to the stabilization and expansion of the total high-dimensional frameworks. For the coexistence of the various weak nonbonding interactions these structures adopted homo or hetero supramolecular synthons or both. Some classical supramolecular synthons, such as R-2(2)(8), R-4(2)(8), R-4(3)(10) and R-4(4)(12), usually observed in the organic solids, were again shown to be involved in constructing most of these H-bonding networks.

Newly synthesised 1,8-naphthyridine-based molecular probes, NAP-1 and NAP-2, exhibit highly selective fluorescence responses towards the toxic cadmium over coordinatively competing Zn2+ and several other metal ions examined. On the one hand, NAP-1 (MeOH:H2O, v/v 80:20, pH 7.4) exhibits ca. 1.5 order of magnitude higher stability constant for Cd2+ over Zn2+; on the other hand, NAP-2 in MeOH offers unique selectivity only towards Cd2+, exhibiting both absorbance and emission red shifts as well as fluorescence enhancement. By 1H NMR analysis, the tetra-coordinated binding is indicated at least for the NAP-1+Cd2+ complex and theoretical calculations reveal relatively stronger binding of Cd2+ over Zn2+. [image omitted].

A new asymmetrical photochromic diarylethene has been synthesized by using 1,8-naphthyridine as a functional group and perfluorodiarylethene as photoswitching unit via a peptide bond linkage, and its molecular structure was characterized by single crystal X-ray diffraction analysis. The compound exhibited favorable photochromism upon irradiation with UV/vis light, and its fluorescent behaviour could be efficiently modulated by light, base/acid, and metal ion in THF. The deprotonated derivative of the diarylethene also showed good photochromism, and displayed remarkable turn-on fluorescence response during photocyclization process. Furthermore, the diarylethene was highly selective toward Cd2+ with an obvious fluorescent color change from dark to bright green in THF. Finally, a logic circuit was fabricated with four inputs of the combinational stimuli of UV/vis and Cd2+/EDTA, and one output of fluorescence intensity. (C) 2016 Elsevier Ltd. All rights reserved.
