Second hyperpolarizability of diffuse-electron compounds M-NH3, M-NLi3 and M-NLi3-M of alkaline earth metals: Effect of lithiation

Present investigation demonstrates that push electron effect of nitrogen in M center dot center dot center dot NH3 is reduced rather than enhanced upon lithiation which has been explained by natural bond orbital analysis showing that nitrogen atom in NLi3 changes it’s state of hybridization from sp(3) to sp(2) leaving the 2p(z), orbital partially occupied. This makes NLi3 a weak acceptor of electrons from alkaline earth metals. When the second alkaline earth metal is introduced the 2p(z), orbital of nitrogen attains the maximum occupation as a result of cumulative charge transfer from two metal atoms. However, the push electron effect still operates resulting in the diffuse electron localized over the metals. Large enhancement of second hyperpolarizability (10(6) au) in M center dot center dot center dot NLi3 has been rationalized by its low lying intense transitions. Effect of basis set on the second hyperpolarizability has been studied at the CCSD level which showed that Sadlej’s pol and 6-311++G(3df,3pd) basis sets give comparable results that are obtained for the aug-cc-pVTZ basis set. The results of second hyperpolarizability calculated by using different OFT functionals are found to be consistent with the CCSD results obtained for the aug-cc-pVTZ basis set. (C) 2019 Elsevier Inc.

Novel sulfenamides and sulfonamides based on pyridazinone and pyridazine scaffolds as CB1 receptor ligand antagonists

A series of sulfenamide and sulfonamide derivatives was synthesized and evaluated for the affinity at CB1 and CB2 receptors. The N-bornyl-S-(5,6-di-p-tolylpyridazin-3-yl)-sulfenamide, compound 11, displayed good affinity and high selectivity for CB1 receptors (K-i values of 44.6 nM for CB1 receptors and > 40 mu M for CB2 receptors, respectively). The N-isopinocampheyl-sulfenamide 12 and its sulfonamide analogue 22 showed similar selectivity for CB1 receptors with K-i values of 75.5 and 73.2 nM, respectively. These novel compounds behave as antagonists/inverse agonists at CB1 receptor in the [S-35]-GTP gamma S binding assays, and none showed adequate predictive blood-brain barrier permeation, exhibiting low estimated LD50. However, testing compound 12 in a supraspinal analgesic test (hot-plate) revealed that it was as effective as the classic CB1 receptor antagonist rimonabant, in reversing the analgesic effect of a cannabinoid agonist.

Intramolecular Reaction of tert-Butyl-NNO-Azoxy and Cyano Groups – Novel Synthesis of Pyridazine, 1,2,3-Triazepine, and Furan Rings

A reaction of (tert-butyl-NNO-azoxy)acetonitrile with N,N-dimethylacetamide dimethylacetal afforded 2,4-bis(tert-butyl-NNO-azoxy)-3-methylpent-2-enedinitrile 9 as a main product. This compound cyclized on silica gel surface with the loss of isobutylene to give 6-amino-5-(tert-butyl-NNO-azoxy)-4-methylpyridazine-3-carbonitrile 2-oxide 10. On the contrary, the cyclization of dinitrile 9 in protic solvents resulted in quite different products: furan, 1,2,3-triazepine, and pyridazine derivatives were among them. These reactions are the first examples of intramolecular reactions of (tert-butyl-NNO-azoxy) and cyano groups.

Strategies to Mitigate the Bioactivation of Aryl Amines

The bioactivation of xenobiotics to yield reactive metabolites can lead to tolerability and toxicity concerns within a drug discovery program. Development of strategies for mitigating the metabolic liability of commonly encountered toxicophores, such as anilines, relies on an understanding of the relative tendency of these functionalities to undergo bioactivation. In this report, we present the first systematic study of the structure-activity relationships of the bioactivation of aryl amine fragments (molecular weight < 250 Da) using a glutathione (GSH) trapping assay in the presence of human liver microsomes and the reduced form of nicotinamide adenine dinucleotide phosphate. This study demonstrates that conversion of anilines to nitrogen-containing heteroarylamines results in a lower abundance of GSH conjugates in the order phenyl > pyrimidine approximate to pyridine > pyridazine. Introduction of electron-withdrawing functionality on the aromatic ring had a less pronounced effect on the extent of GSH conjugation. Examination of more drug-like compounds sourced from in-house drug discovery programs revealed similar trends in bioactivation between matched pairs containing (hetero)aryl amines. This study provides medicinal chemists with insights and qualitative guidance for the minimization of risks related to aryl amine metabolism.

Why lithiation results large enhancement of second hyperpolarizability of delta shaped complexes M-C2H2 (M = Be, Mg and Ca)?

Lithiation of M-C2H2 results significant enhancement of second-hyperpolarizability. The negatively polarized pi-surface of C2Li2 raises the molecular orbital energies which strongly favours both metal-HOMO to ligand-LUMO and ligand-HOMO to metal-LUMO charge transfer interactions. Due to the push electron effect by C2Li2 , the outermost ‘ns’ orbital of alkaline earth metal cannot induce charge transfer instead forms the excess diffuse electron density localized over the alkaline earth metal. Calculated vertical ionization energy of M-C2Li2 complexes are smaller than the corresponding isolated metals. CCSD calculated static and dynamic second-hyperpolarizabilities of M-C2Li2 complexes are many times larger than that of the corresponding M-C2H2 complexes.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 5469-69-2, you can contact me at any time and look forward to more communication. SDS of cas: 5469-69-2.

Removal of chloridazon pesticide from waters by Fenton and photo-Fenton processes

Chloridazon (CLZ), also named as Pyrazon and classified as organochlorine pesticides, is widely used during sugar beets cultivation. CLZ being a pesticide with high solubility in water is likely to end up in surface and groundwater bodies because of its high mobility in soil. Due to its toxic properties, it may cause serious problems in human health and ecological cycle. In the present study, the removal of CLZ pesticide by Fenton and photo-Fenton processes was investigated. The effects of parameters such as H2O2, Fe(II), initial CLZ concentration, pH, and temperature were studied. It was observed that CLZ completely disappeared within 1 h and 20 min by the Fenton and photo-Fenton process, respectively, under optimal conditions. The optimal conditions for each processes were attained as 7.5 mg/L Fe(II), 50 mg/L H2O2, 40 mg/L initial CLZ, pH, and 20 degrees C for Fenton process, and 5 mg/L Fe2+, 50 mg/L H2O2, 60 mg/L initial CLZ, pH 3 and 20 degrees C for photo-Fenton process. The reaction kinetics of CLZ followed Behnajady-Modirdhahla-Ghanbery kinetic model. Desphenyl CLZ, pyridazine-3,4,5-trione, oxaluric acid, and 5-hydroxyhydantion were identified as CLZ degradation by-products. Accordingly, the degradation pathway was proposed.

Synthesis of New Isoxazole-, Pyridazine-, Pyrimidopyrazines and their Anti-Inflammatory and Analgesic Activity

Background: Isoxazoles, pyridazines, and pyrimidopyrazines have recently attracted attention due to their potent pharmacological activities. They exhibited anticancer, neuroprotective, analgesic and anti-inflammatory effects. Objective: The study aimed to synthesize novel isoxazoles, pyridazines, and pyrimidopyrazines through efficient high yield protocol for evaluating their analgesics and anti-inflammatory activities. Method: A series of novel isoxazole-, pyridazine-, pyrimidopyrazine derivatives was prepared from 5,8-alkyl-1,3-dimethyl-5,6-dihydropynmido[5,6-e]pyrazine-2,4,7-trione (1a,b) as the starting material. Results: The prepared derivatives were synthesized in moderate to good yields (60-75%) in a stepwise efficient protocol under mild condition. These new compounds have been proven by several spectroscopic techniques as IR, 1D and 2D NMR techniques and mass analysis. The in vivo anti-inflammatory was assessed for the synthesized compounds using carrageenan-induced rat hind paw edema model. Also, the in vivo analgesic activity for these products was examined utilizing hot-plate and acetic acid-induced writhing response assays. Conclusion: The isoxazole derivatives (3a-f) showed the most forceful anti-inflammatory and analgesic activities. Pyrimidopyrazines (4a-f) demonstrated weaker but comparable antiinflammatory and analgesic activities to the positive controls.
