Abstract

HAL is a multi-disciplinary open access archive for the deposit and dissemination of scientific research documents, whether they are published or not. The documents may come from teaching and research institutions in France or abroad, or from public or private research centers. L'archive ouverte pluridisciplinaire HAL, est destinée au dépôt et à la diffusion de documents scientifiques de niveau recherche, publiés ou non, émanant des établissements d'enseignement et de recherche français ou étrangers, des laboratoires publics ou privés.

Synthesis, nanostructuring and in silico studies of a new imine bond containing a macroheterocycle as a promising PBP-2a non-β-lactam inhibitor

“…This way the minimum inhibitory concentration (MIC) is considered as the concentration after which the tested compounds do not inhibit this change in colour. 44–47…”

“…This way the minimum inhibitory concentration (MIC) is considered as the concentration after which the tested compounds do not inhibit this change in colour. [44][45][46][47] Computational studies. Quantum chemical calculations of MHC3 were performed using Gaussian software.…”

“…Quantum chemical calculations of MHC3 were performed using Gaussian software. [46][47][48][49] B3LYP, one of the DFT hybrid functions, was selected as the calculation method with a 6-31G basis set. All calculations were performed in the water phase and the C-PCM solvent method was used for this purpose.…”

Catalytic role in Biginelli reaction: Synthesis and biological property studies of 2‐oxo/thioxo‐1,2,3,4‐tetrahydropyrimidines

“…The antifungal activity of compounds 15 and 16 was determined against C. albicans and A. niger , and compounds 15 and 16 demonstrate pronounced antifungal activity. [ 94 ] Selvinthanuja et al examined the synthesis of azo‐coupled 3,4‐dihydropyrimidine‐2‐one derivatives from the reaction of 2‐oxo‐1,2,3,4‐tetrahydropyrimidines and p ‐nitroaniline diazonium salts. All of the synthesized compounds had modest antibacterial and antifungal activity against bacterial strains like S. aureus and E. coli , as well as fungal strains like C. albicans and A. niger .…”

Graphene Oxide-Modified Dihydropyrimidines

“…One-pot multicomponent reactions are a very effective synthetic technique and a flexible tool for building different classes of compounds with a broad range of applications. Because multicomponent reactions provide a synthetic chemist intrinsically substantial benefits over traditional linear-type synthesis, such as straightforward operation, simple starting ingredients, high product complexity, and enormous product variety, interest in them is rising [1][2][3][4]. A three-component one-pot Biginelli reaction is one of these kinds of reactions that was used in the synthesis of heterocycles.…”
