Isoxazole-containing neonicotinoids: Design, synthesis, and insecticidal evaluation

A series of novel isoxazole-containing neonicotinoids were synthesized from nitromethylene analogues and aromatic aldehydes in the presence of L-proline/K2CO3. Bioassays indicated that several synthesized compounds showed 40-70% mortality against brown planthopper (Nilaparvata lugens) under the concentration of 4 mg L-1, higher than that of imidacloprid (20%). Against cowpea aphid (Aphis craccivora), the best activity of title compounds reached 90% at the concentration of 20 mg L-1. (C) 2017 Published by Elsevier Ltd.

Synthesis of fluorinated triazole and isoxazole derivatives by electrochemical fluorination

Partially fluorinated triazole derivatives were synthesized through anodic fluorination of allcynes having arylthio group and following Cu(I)-catalyzed azide-alkyne cycloaddition (CuAAC) with benzyl azide. The other route toward the fluorinated triazoles, namely the anodic fluorination of triazole derivatives once prepared by advanced CuAAC of the alkyne and azide above was also investigated. It was shown that these two routes are mutually complementary methodology for the synthesis of new mono- and difluoromethyltriazole derivatives. Furthermore, Cu(I)-catalyzed isoxazole synthesis from fluorinated alkynes and imidoyl chloride was demonstrated. (C) 2016 Elsevier Ltd. All rights reserved.

Tuning Behaviors of Methane Inclusion in Isoxazole Clathrate Hydrates

In this study, the inclusion of methane (CH4) gas in isoxazole (C3H3NO) clathrate hydrates was investigated through spectroscopic observations, such as powder X-ray diffraction (PXRD) and Raman spectroscopy. PXRD patterns of isoxazole clathrate hydrates having two different mole fractions of water were analyzed, and Raman spectroscopy was used to understand the CH4 inclusion behaviors in the hydrate cavities. Raman spectra indicated that CH4 can be captured in both small and large cavities of structure II hydrate in the C3H3NO with 34H(2)O system, while CH4 can be entrapped in only small cavities of structure II hydrate in the C3H3NO with 17H(2)O system. The PXRD result showed both clathrate hydrate samples exhibit the same cubic Fd3m structure II hydrate as expected. However, the structure II hydrate in the C3H3NO with 34H(2)O system includes a small amount of hexagonal ice and structure I CH4 hydrate. The phase equilibrium conditions of the binary (isoxazole + CH4) clathrate hydrate were also identified through high-pressure micro differential scanning calorimetry (MicroDSC), and the equilibrium temperatures of the binary (isoxazole + CH4) clathrate hydrate at given pressures are higher than those of the structure I CH4 hydrate.

Novel isoxazole carboxamides as growth hormone secretagogue receptor (GHS-R) antagonists

Novel isoxazole carboxamides have been identified as growth hormone secretagogue receptor (GHS-R) antagonists. Substituent modification off the 5-position of the isoxazole ring led to analogues with potent binding affinity and functional antagonism of GHS-R. A potent analogue (32) with high aqueous solubility and good GPCR selectivity was also identified as a potential pharmacological tool for in vivo studies. (C) 2004 Elsevier Ltd. All rights reserved.

Synthesis and anti-nociceptive potential of isoxazole carboxamide derivatives

Background: Isoxazole is an important pharmacophore in medicinal chemistry with a wide range of pharmacological activities. The present study deals with the synthesis and evaluation of antinociceptive potential of nine novel 3-substituted-isoxazole-4-carboxamide derivatives. Synthesis: In the first step, respective oxime was prepared and further treated with ethylacetoacetate and anhydrous zinc chloride followed by hydrolysis of ester to furnish 3-substituted isoxazole-4-carboxylic acid. The respective carboxylic acids were converted to acid chlorides and condensed with aromatic amines to get the target carboxamide derivatives (A1-A5 and B1-B5). These compounds were characterized by FTIR, (HNMR)-H-1, (CNMR)-C-13 and elemental analysis data and screened for their analgesic activity using acetic acid-induced writhing assay and hot plat test in mice and compared with the standard centrally acting analgesic, tramadol. Results: All the synthesized carboxamide derivatives showed low to moderate analgesic activity. Among the synthesized derivatives B2 having methoxy (OCH3) showed high analgesic activity as compared to tramadol both in acetic acid-induced writhing assay and hot plate assay at dose of 6 mg/kg. To examine the involvement of opioidergic mechanism in the mediation of analgesic effects of isoxazole derivatives animals were further treated with nonselective opioid analgesic, naloxone (0.5 mg/kg). The results showed that compounds A3 and B2 follow a non-opioid receptor pathway in the mediation of analgesic effects. Synthesized compounds A3 and B2 were docked against non-opioid receptors COX-1 (3N8X), COX-2 (1 PXX) and human capsaicin receptor (HCR, 3J9J) to analyze their binding interactions. They showed binding energies in the range of – 7.5 to -9.7 kcal/mol. Conclusions: The results indicated that isoxazole carboxamide derivatives possess moderate analgesic potential especially compounds A3 and B2 can be considered as lead molecules and explored further for pain management with fewer side effects.
