Synthesis, characterisation, conformational preferences, dynamic NMR studies and antimicrobial evaluation of N-nitroso- and N-formyl-c-3,t-3-dimethyl-r-2,c-7-diphenyl-1,4-diazepan-5-ones

The stereochemical preferences of N-nitroso- and N-formyl-c-3,t-3-dimethyl-r-2,c-7-diphenyl-1,4-diazepan-5-ones 3 & 4, respectively, have been determined using 1D and 2D NMR spectral techniques. Interestingly, the N-nitroso compound 3 is found to prefer a

Design, synthesis, molecular docking and antimicrobial evaluation of some tosyl carbamate derivatives

A series of tosyl carbamates have been synthesized and screened for their antibacterial and antifungal activities. All the synthesized compounds were characterized by spectral techniques (IR, 1H, 13C NMR and mass) and elemental analysis. in silico Molecular docking method was performed to study their antimicrobial activity against the target protein 1T9U. Compound 27 showed good antibacterial activity against Gram-positive and Gram-negative bacterial strains and compound 19 showed good antifungal activity. Molecular docking results revealed that the compound 19 exhibits minimum CDOCKER energy. Tosyl carbamate derivatives having good antimicrobial activities compared to that standard and all the synthesized compounds exhibits moderate CDOCKER scores.

Synthesis, stereochemical and biological studies of some N-cyclohexylcarbamoyl -2,6-diarylpiperidin-4-ones

A series of N-cyclohexylcarbamoylpiperidin-4-ones were synthesized by the addition reaction of corresponding piperidin-4-ones with cyclohexylisocyanate in benzene. The structure and stereochemistry of the synthesized N-cyclohexylcarbamoyl -2, 6-diarylpiperidin-4-ones, were established on the basis of their analytical and spectral data (IR, 1H and 13C NMR). 2D NMR spectra (HOMOCOSY, HSQC, HMBC and NOESY) were also recorded to analyze the stereochemistry. In the IR spectra of synthesized compounds, the characteristic absorptions due to ring and amide carbonyl functionalities were observed which evidences the formation of N-cyclohexylcarbamoyl-2, 6-diarylpiperidin-4-ones. NMR spectral results are in line with the proposed structure of the compounds synthesized. Conformational analysis was carried out from the extracted coupling constants and NOESY spectral results. The synthesized compounds were evaluated for their antibacterial and antifungal activities.

Stereoselective synthesis and spectral studies of some benzotriazolylacetyl hydrazones of 3–alkyl–2,6–diarylpiperidin–4–ones

An effort to include biologically potent benzotriazole nucleus into piperidine ring is achieved through hydrazone formation. The characterization of the synthesized compounds was carried out using FT-IR, 1H &13C NMR, 1H–1H COSY, 1H–13C COSY, NOESY spectral techniques and GC-Mass spectrum. The spectral assignments were done without ambiguity using 2D-NMR techniques. The conformational preference of the piperidine ring deduced from the spectral studies is ‘chair’. The diastereotopic nature of the methylene protons/methyl groups present in the molecules is revealed clearly in their spectral pattern observed.

Synthesis, spectral characterization, crystal structure and molecular docking study of 2,7-diaryl-1,4-diazepan-5-ones

In this study, a series of variously substituted r-2,c-7-diaryl-1,4-diazepan-5-ones 9-16 have been synthesized using Schmidt rearrangement and are characterized by IR, mass and 1D & 2D NMR spectral data. The proton NMR coupling constant and estimated dihedral angles reveal that the compounds 9-16 prefer a chair conformation with equatorial orientation of alkyl and aryl groups. Single crystal X-ray structure has been solved for compounds 9 and 11 which also indicates the preference for distorted chair conformation with equatorial orientation of substituents. The compounds 9-16 have been docked with the structure of Methicillin-resistant Staphylococcus aureus (MRSA) and the results demonstrate that compound 10 is having better docking score and glide energy than others and it is comparable to co-crystal ligand. Furthermore, all the compounds have been evaluated for their antibacterial and antioxidant activities. All the compounds show moderate antibacterial activity and only 11 exhibits better activity against S. aures and Escherichia coli. The compounds 11, 13 and 14 exhibit half of the antioxidant power when compared to the BHT and the remaining compounds show moderate activity.
