Branching is an important mechanism of plant shape establishment and the direct consequence of axillary bud outgrowth. Recently, hydrogen peroxide (H2O2) metabolism, known to be involved in plant growth and development, has been proposed to contribute to axillary bud outgrowth. However, the involvement of H2O2 in this process remains unclear. ? Methods We analyzed the content of H2O2 during bud outgrowth and characterized its catabolism, both at the transcriptional level and in terms of its enzymic activities, using RT-qPCR and spectrophotometric methods, resp. In addition, we used in vitro culture to characterize the effects of H2O2 application and the reduced glutathione (GSH) synthesis inhibitor L-buthionine sulfoximine (BSO) on bud outgrowth in relation to known mol. markers involved in this process. ? Key Results Quiescent buds displayed a high content of H2O2 that declined when bud outgrowth was initiated, as the consequence of an increase in the scavenging activity that is associated with glutathione pathways (ascorbate-glutathione cycle and glutathione biosynthesis); catalase did not appear to be implicated. Modification of bud redox state after the application of H2O2 or BSO prevented axillary bud outgrowth by repressing organogenesis and newly formed axis elongation. Hydrogen peroxide also repressed bud outgrowth-associated marker gene expression. ? Conclusions These results show that high levels of H2O2 in buds that are in a quiescent state prevents bud outgrowth. Induction of ascorbate-glutathione pathway scavenging activities results in a strong decrease in H2O2 content in buds, which finally allows bud outgrowth.

Ascorbate glutathione-dependent H2O2 scavenging is an important process in axillary bud outgrowth in rosebush. Recommended basis is Sulfoximine, Bioisosteric. Products is: https://www.ambeed.com/products/50578-18-2.html, 145026-07-9

In this work, the chem. composition of Thymus zygis subsp. gracilis collected from Ifrane, Morocco, along with the evaluation of the antibacterial, anti-biofilm of Listeria monocytogenes activities, larvicidal effect against L3 larvae of Anisakis, and antioxidant properties of its essential oil (TZG-EO), are reported. GC-MS and GC-FID analyses highlighted the presence of 84 volatile components and strong bactericidal and anti-biofilm activities against L. monocytogenes at a concentration of 0.02 % were demonstrated. Also, larvicidal effect against Anisakis larvae at concentrations of 0.01 and 0.005 % was attained leading to the death of all tested larvae within 4 h. The in situ antibacterial activity of TZG-EO (0.01 and 0.005 %) in smoked fish showed high efficiency against L. monocytogenes growth. TZG-EO could be used as potential antibacterial and larvicidal agents for fighting against foodborne pathogens and extending shelf life of food products.

This study reports antidiabetic activity of leaf essential oil (EO) of Cinnamomum travancoricum from the Western Ghats, India via in vitro , in vivo and in silico methods. EO was characterized by GC-MS and GC-FID. Essential oil nanoemulsions (EN) were prepared and characterized. Antidiabetic potential was evaluated through in vitro assays namely, ¦Á-amylase and ¦Á-glucosidase inhibition, glucose uptake and insulin secretion assays. In vivo study was conducted on STZ-induced diabetic Wistar rats. Mol. docking was conducted to find the lead antidiabetic compounds Of the 42 compounds identified in the EO, ¦Á-phellandrene (5.9%), ¦Â-phellandrene (12.6%), linalool (23.6%), safrole (6.8%) and shyobunol (5.1%) were major constituents. Of the two ENs formulated, 1:2 ratio (EO to surfactants) was better in zeta size (51.4 nm) and potential (-30.9). In vitro results were impressive. EN lowered elevated blood glucose level to normal (p < 0.01) and improved the insulin secretion (p < 0.01) in diabetic rats. Further, serum AST, ALT, ALP, triglyceride and pancreatic ¦Â-cell damage were seen reduced (p < 0.05). Mol. docking studies showed minor constituents of EO, namely, ¦Ä-cadinene, elemol, spathulenol and ¦Á-copaen-11-ol playing active role in antidiabetic activity through ¦Á-amylase, ¦Á-glucosidase, insulin receptor, and insulin secretion proteins.

A new system for NH transfer is developed for the preparation of sulfoximines, which are emerging as valuable motifs for drug discovery. The protocol employs readily available sources of nitrogen without the requirement for either preactivation or for metal catalysts. Mixing ammonium salts with diacetoxyiodobenzene directly converts sulfoxides into sulfoximines. This report describes the first example of using of ammonia sources with diacetoxyiodobenzene to generate an electrophilic nitrogen center. Control and mechanistic studies suggest a short-lived electrophilic intermediate, which is likely to be PhINH or PhIN+.

Dichloro-isoproterenol (I) is known to prevent both adrenaline (II)-induced increase of contractile force and activation of phosphorylase in the dog heart in situ. The present study demonstrates that I almost completely abolishes the increase in blood sugar and free fatty acids induced by II, noradrenaline (III), and isoproterenol in the dog. The hyperlactic-acidemic effect of II is partly blocked. I does not block II-induced hyperglycemia in mice. In contrast to I, phenoxybenzamine (IV) does not affect the hyperglycemia or increase in blood lactic acid induced by II in the dog. Ergotamine antagonizes the hyperglycemia but not the increase in lactic acid. IV effectively blocks the vasopressor response to II and III, and ergotamine produces maximal reversal of II. None of these drugs in the doses used antagonized the pos. inotropic effect of adrenergic stimuli. Both I and IV increase blood glucose and lactic acid. High doses of I appear to antagonize the hyperglycemic action of low doses. The hyperglycemia and lactic acid increase produced by IV are antagonized by I. I also produces a marked and sustained increase in free fatty acids even with doses which do not block the action of II. Possible mechanisms of action are discussed.

An efficient copper-TBAF-catalyzed C-N bond formation of sulfoximines with aryltrialkoxysilanes in dichloromethane at room temperature, affording the desired N-aryl sulfoximines in good to excellent yields under an oxygen atm., is reported. E.g., in presence of CuI-TBAF, N-arylation of sulfoximine derivative (I) with PhSi(OMe)3 gave 80% II. This method complements the existing synthetic approaches due to some advantageous properties of aryltrialkoxysilanes such as availability, low toxicity, ease of handling, high stability, and environmental benignity under mild reaction conditions, thus opening a new approach to practical C-N bond formation.
