A new synthesis of 2,7-dimethyl-1,8-naphthyridine (dmnap) from 2-methyl-1,8-naphthyridine (mnap) upon treatment with 3 equiv of methyllithium is described.Oxidation of dmnap with 8 equiv of N-chlorosuccinimide gave (98percent) 2,7-bis(trichloromethyl)-1,8-naphthyridine (2), while oxidation with 4 equiv gave (97percent) 2,7-bis(dichloromethyl)-1,8-naphthyridine (1).Hydrolysis of 2 phosphoric acid followed by esterification gave the corresponding diester 3 in 80percent overall yield.Reduction of 3 with NaBH(OMe)3 afforded (55percent) diol 4.Similar functionalization of mnap afforded 2-(trichloromethyl)-1,8-naphthyridine (6) in 85-94percent yield along with 6-chloro-2-(trichloromethyl)-1,8-naphthyridine (7).Methanolysis of 6 gave (78percent) 2-(methoxycarbonyl)-1,8-naphthyridine (8), which upon reduction with NaBH(OMe)3 afforded (59percent) the alcohol 9.Treatment of 6 with KOH caused a displacement of the trichloromethyl moiety, generating 1,8-naphthyridin-2-one (10) as the sole product.Similarly, 2 gave 7-(trichloromethyl)-1,8-naphthyridin-2-one (11) under mild conditions or 7-(ethoxycarbonyl)-1,8-naphthyridin-2-one (12) when refluxed.

A new kind of co-crystal of buprofezin (C16H24FN3OS) with hydrofluoric acid has been prepared through evaporation technique. It crystallizes in the triclinic space group P1, with alpha = 9.9733(8), b = 10.3460(9), c = 10.5739(12) A, alpha = 68.655(9), beta = 73.291(9), gamma= 66.738(8), V = 920.34(17) A3, Mr = 325.44, Dc = 1.174 g/cm3, Z = 2, F(000) = 348, mu= 0.190 mm-1, the final GOOF = 1.042, R = 0.0485 and wR = 0.1167. Single-crystal X-ray diffraction, XRPD, DSC, TGA, Hirshfeld surface analysis, Raman spectroscopy and FT-IR were used to characterize the co-crystal. It has a two-dimensional plane structure, and the intermolecular interactions of co-crystal are mainly H-F H, H-O H and H-O H. Thermology study further confirmed that co-crystal has stronger thermal stability and higher melting point than buprofezin, and it has stronger water solubility. The results show that this co-crystal is valuable for the study of residual activity and application effects of buprofezin.

Recently, four subtypes of the human phosphodiesterase type 4 (PDE4A-D) enzyme have been described. So far, only very few PDE4 subtype-selective inhibitors are known. Herein, we describe the synthesis of 6,8-disubstituted 1,7-naphthyridines and their characterization as potent and selective inhibitors of PDE4D which suppress the oxidative burst in human eosinophils with IC50 values as low as 0.7 nM. SAR development and the extended use of palladium-catalyzed cross-coupling reactions led to compound 11 which inhibited human PDE4D with an IC50 value of 1 nM. Thus, compound 11 was 55, 175, and 1000 times more potent in inhibiting PDE4D over PDE4B, PDE4A, and PDE4C. In a Brown Norway rat model of allergic asthma, compound 11 when given by the oral route (1 mg/kg) reduced by more than 50% the influx of eosinophils, T-cells, and neutrophils into bronchoalveolar lavage fluid (BALF) samples obtained from antigen-challenged animals. Thus, PDE4D- selective inhibitors of the 1,7-naphthyridine class have the potential as an oral therapy for treating asthma.

Pressure-induced irreversible chemical reactions of naphthalene, 2,3-naphthyridine (2,3-Nap), and 1,5-naphthyridine (1,5-Nap) were observed after compression (>16?18 GPa) at room temperature. Regardless of the initial materials, amorphous products in which sp3 carbon was formed were obtained after the samples were recovered at ambient pressure. The X-ray photoelectron spectroscopy (XPS) of the product from naphthalene indicated that the carbon sp3/sp2 ratio was much lower than that of benzene nanothreads. Nitrogen remained in the amorphous products from 1,5-Nap and 2,3-Nap and bonded to both sp3 and sp2 carbons.

Cannabis has long been known to limit or prevent nausea and vomiting, lack of appetite, and pain. For this reason, cannabinoids have been successfully used in the treatment of some of the unwanted side effects caused by cancer chemotherapy. Besides their palliative effects, research from the past two decades has demonstrated their promising potential as antitumor agents in a wide variety of tumors. Cannabinoids of endogenous, phytogenic, and synthetic nature have been shown to impact the proliferation of cancer through the modulation of different proteins involved in the endocannabinoid system such as the G protein?coupled receptors CB1, CB2, and GRP55, the ionotropic receptor TRPV1, or the fatty acid amide hydrolase (FAAH). In this article, we aim to structurally classify the antitumor cannabinoid chemotypes described so far according to their targets and types of cancer. In a drug discovery approach, their in silico pharmacokinetic profile has been evaluated in order to identify appropriate drug-like profiles, which should be taken into account for further progress toward the clinic. This analysis may provide structural insights into the selection of specific cannabinoid scaffolds for the development of antitumor drugs for the treatment of particular types of cancer.

A systematic study on the condensation reaction of 2,4-dichlorobenzo[. h]quinoline and naphth-1-ylamine in the presence of CuI as catalyst to functionalised mono- and di-substituted (naphthalen-1-yl)benzo[. h]quinoline amines was described. Subsequently these mono- and di-substituted amines on polyphosphoric acid catalysed cyclisation reaction with aromatic/heteroaromatic carboxylic acids led to the construction of angular and linear aromatic/heteroaromatic substituted dinaphthonaphthyridines in good yields.
