Abstract:
A novel design strategy for cocrystals of a sulfonamide drug with pyridine carboxamides and cyclic amides is developed based on synthon identification as well as size and shape match of coformers. Binary adducts of acetazolamide (ACZ) with lactams (valerolactam and caprolactam, VLM, CPR), cyclic amides (2-pyridone, labeled as 2HP and its derivatives MeHP, OMeHP) and pyridine amides (nicotinamide and picolinamide, NAM, PAM) were obtained by manual grinding, and their single crystals by solution crystallization. The heterosynthons in the binary cocrystals of ACZ with these coformers suggested a

Abstract:
A series of new spiro 1,2,4-triazoles V-IXa-j were synthesized by the reaction of appropriate amidrazones IV with cyclic ketones in the presence of p-toluene sulfonic acid as a catalyst. The structures of the synthesized compounds have been confirmed by the elemental analysis and spectroscopic data (IR, 1H NMR, 13C NMR and MS). The microbial features of the synthesized compounds were studied using well-established methods from the literature.

Abstract:
The polarographic and cyclic voltammetric behaviour of (2-hydroxyphenylazo)-4-benzenesulfonamide and some of its derivatives have been studied in Britton-Robinson buffer series containing 30 vol.% of DMF. Over the entire pH range (2-12), the reduction pathway occurs through an irreversible 4-electron step corresponding to the reduction of N=N center to the amine stage. The voltammograms recorded in acidic and alkaline solution at different scan rates exhibit one or two cathodic peaks depending on the substituent and the pH of the medium. The electrode reaction mechanism was suggested, also the

Abstract:
Although a monoclonal antibody targeting the multifunctional ectoenzyme CD38 is an FDA-approved drug, few small molecule inhibitors exist for this enzyme that catalyzes inter alia the formation and metabolism of the N1-ribosylated, Ca2+-mobilizing, second messenger cyclic adenosine 5′-diphosphoribose (cADPR). N1-Inosine 5′-monophosphate (N1-IMP) is a fragment directly related to cADPR. 8-Substituted-N1-IMP derivatives, prepared by degradation of cyclic parent compounds, inhibit CD38-mediated cADPR hydrolysis more efficiently than related cyclic analogues, making them attractive for inhibitor d

<strong>Abstract </strong>A Density Functional Theory study was carried out to find relationships between the elctronic structure and the SARS-CoV-2 virus inhibition by a group of cyclic sulfonamide derivatives. The molecular geometries were fully optimized at the B3LYP/6-31g(d,p) level. The electronic structure was calculatedat the same level of theory. From the results, the numerical values of several local atomic reactivity indices belonging to a molecular skeleton common to all molecules were calculated. These values were employed with a formal equation developed by Klopman, Peradejodi and

Ce travail consiste en l'étude de la réaction de métallation en série diazinique. Dans une première partie, nous avons pu mettre en évidence pour la première fois en série diazinique, un mécanisme d'halogen-dance avec migration de l'iode. De plus, nous avons pu observer pour la première fois dans cette série, un exceptionnel échange iode-métal avec les alkylamidures de lithium. Cette réaction a été appliquée à la synthèse de leshmaniacides. Dans une seconde partie, nous avons mis au point l'amination électrophile par métallation en série diazinique.
