The presented study comprises the synthesis of a new series of ethylated sulfonamides in which 1,4- benzodioxane moietyhas been incorporated. The reaction of 1,4-benzodioxane-6-amine (1) with ethane sulfonyl chloride (2) yielded N-(2,3-dihydrobenzo[1,4]dioxin-6-yl)ethanesulfonamide (3), which further on treatment with various alkyl/aralkyl halides, 4a-r, in N,N?-dimethylformamide (DMF) and in the presence of lithium hydride (LiH) acting as a weak base and catalyst;yielded derivativesofN-alkyl/aralkyl substituted N-(2,3-dihydrobenzo[1,4]dioxin-6- yl)ethanesulfonamides (5a-r). The characterization of these derivatives was carried out by different spectroscopic techniques like infra red, proton-NMR and mass spectrometry; then screened against various enzymes i.e. acetylcholinesterase, butyrylcholinesterase, lipoxygenase and alpha-glucosidase enzymes and five different bacterial strains. The synthesized compounds were found to be good inhibitors of lipoxygenase but moderate inhibitors of AChE, BChE and a-glucosidase; whereas compounds 3, 5a, 5f, 5n and 5r were found good antibacterial compounds. The interaction between inhibitors and target enzymes (cholinestrases and lipoxygenase) was computationally observed which correlated with the experimental results.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Safety of 2,3-Dihydrobenzo[b][1,4]dioxin-6-amine, you can also check out more blogs about22013-33-8

Thermochemical conversion processes such as supercritical fluid extraction are used for producing biofuels from biomass. Supercritical fluid extraction process is decomposition process of lignocellulose or other organic materials thermally under supercritical conditions at 250-400 C temperature range under high pressure (4-5 MPa). In this study, the supercritical fluid extraction was used to produce bio-oils from algae. Supercritical fluid extraction trials were performed in a cylindrical reactor (75 mL) in organic solvents (acetone, ethanol and isopropanol) under supercritical conditions with (ferric chloride, potassium hydroxide) and without catalyst at the temperatures of 255, 275 and 295 C. The effects of process variables including temperature and catalyst on product yields were investigated. The produced liquids at 295 C in supercritical liquefaction were analyzed and characterized by elemental, GC-MS and FT-IR. 160, 122 and 108 different types of compounds were identified by GC-MS obtained in acetone, ethanol and isopropanol respectively. Bio-oils from supercritical liquefaction were composed of various organics including aromatics, nitrogenated and oxygenated compounds. Bio-oils obtained from supercritical liquefaction were found to have higher calorific values and superior fuel properties compared to feedstock.

Staphylococcus aureus and Mycobacterium tuberculosis are major causative agents responsible for serious nosocomial and community-acquired infections impacting healthcare systems globally. Over several decades, these pathogens have developed resistance to multiple antibiotics significantly affecting morbidity and mortality. Thus, these recalcitrant pathogens are amongst the most formidable microbial pathogens for which international healthcare agencies have mandated active identification and development of new antibacterial agents for chemotherapeutic intervention. In our present work, a series of new quinazolin-4(3H)-one derivatives were designed, synthesized and evaluated for their antibacterial activity against ESKAP pathogens and pathogenic mycobacteria. The experiments revealed that 4’c, 4’e, 4’f and 4’h displayed selective and potent inhibitory activity against Staphylococcus aureus with MIC values ranging from 0.03-0.25 mug/mL. Furthermore, compounds 4’c and 4’e were found to be benign to Vero cells (CC50 = >5 mug/mL) and displayed promising selectivity index (SI) > 167 and > 83.4 respectively. Additionally, 4’c and 4’e demonstrated equipotent MIC against multiple drug-resistant strains of S. aureus including VRSA, concentration dependent bactericidal activity against S. aureus and synergized with FDA approved drugs. Moreover, compound 4?c exhibited more potent activity in reducing the biofilm and exhibited a PAE of ?2 h at 10X MIC which is comparable to levofloxacin and vancomycin. In vivo efficacy of 4’c in murine neutropenic thigh infection model revealed that 4’c caused a similar reduction in cfu as vancomycin. Gratifyingly, compounds 4d, 4e, 9a, 9b, 14a, 4’e and 4’f also exhibited anti-mycobacterial activity with MIC values in the range of 2-16 mug/mL. In addition, the compounds were found to be less toxic to Vero cells (CC50 = 12.5->100 mug/mL), thus displaying a favourable selectivity index. The interesting results obtained here suggest the potential utilization of these new quinazolin-4(3H)-one derivatives as promising antibacterial agents for treating MDR-Staphylococcal and mycobacterial infections.

A new metal-free procedure allowing Csp3?N bond formation through coupling of pyridotriazoles and weakly nucleophilic anilines has been developed. This sustainable reaction shows high tolerance towards functional groups (ketones, free alcohols) leading to 2-picolylamine derivatives. The key to our success is the use of a catalytic amount of TBAB and water as a co-solvent leading to the formation of pyridylalkylamine derivatives. As this coupling tolerates the presence of Csp2?Br bond on both partners of the reaction, we performed a sequential one-pot reaction between functionalized triazolopyridines and anilines followed by a second coupling with N-tosylhydrazones leading to the formation of Csp3?N and Csp2?Csp2 bonds.

The synthesis of new substituted dioxino[b]- and [c]phenothiazines or acridinones is reported. N-Arylation of [1,4]benzodioxin-6-amine with organolead or organobismuth reagents gave N-aryl-2,3-dihydro-1,4-benzodioxin-6-amine; subsequent Bernthsen thionation led to phenothiazine ring formation, followed by N-acylation. On the other hand [1,4]benzodioxin-6-amine was first N-alkylated and the resulting alkylamines were N-phenylated before Bernthsen thionation to provide the tetracyclic phenothiazines. Alternative arylation with chlorobenzoic acid followed by cyclization under acidic conditions afforded the dioxinoacridinones, which were successfully alkylated.
