Novel Sulfonylamido Benzoxazole Derivatives: Synthesis, Characterisation, Molecular Docking, DFT, and Antimicrobial Activity Investigations.

In this work, numerous novel 2-(p-ethyl/fluorophenyl)-5-[(p-substitutedphenyl)sulfonylamido]benzoxazole derivatives were designed, synthesized, and structurally characterized using H-NMR, C-NMR, mass spectroscopy, and elemental analysis approaches. The antimicrobial activity against several Gram (+) bacteria, Gram (-) bacteria, and fungal species was determined using the in vitro microdilution technique. A molecular docking analysis was performed on all produced compounds utilizing the S.

Design, synthesis, molecular docking, density functional theory and antimicrobial studies of some novel benzoxazole derivatives as structural bioisosteres of nucleotides.

A series of some novel 2-(-tert-butylphenyl)-5-(3-substituted-propionamido)benzoxazole derivatives have been designed, synthesized, evaluated for antimicrobial activity and have performed molecular docking studies against penicillin-binding protein 4 (PBP4) and active and allosteric site of PBP2a; were calculated some theoretical quantum parameters and absorption, distribution, metabolism and excretion (ADME) descriptors. acted at minimum inhibitory concentration (MIC) = 8 µg/mL against and their drug-resistant isolates and also formed with GLU145 (1.74 Å) and ILE144 (1.

Biological evaluation and docking studies of some benzoxazole derivatives as inhibitors of acetylcholinesterase and butyrylcholinesterase.

A series of 2,5-disubstituted-benzoxazole derivatives (1-13) were evaluated as possible inhibitors of acetylcholinesterase (AChE) and butyrylcholinesterase (BChE). The results demonstrated that the compounds exhibited a broad spectrum of AChE and BChE inhibitory activity ranging between 6.80% and 90.

Synthesis and antimicrobial evaluation of some novel sulfonylamido-benzoxazoles.

A series of 2-(p-substituted phenyl)-5-[(4-substituted phenyl) sulfonylamido]-benzoxazoles were synthesized and tested for their antimicrobial activities. The structures of the new derivatives were elucidated by spectral techniques. The minimum inhibitory concentrations (MIC) of the new benzoxazoles were determined against standard bacterial and fungal strains and drug-resistant isolates and compared to those of several reference drugs.

Synthesis and antimicrobial evaluation of 2-(p-substituted phenyl)-5-[(4-substituted piperazin-l-yl)acetamido]-benzoxazoles.

A series of 2-(p-substituted phenyl)-5-(2-{4-[(p-chloro-fluorophenyl)/phenyl] piperazin-1-yl}acetamido)-benzoxazoles were synthesized and tested for their antimicrobial activities. The structures of the new derivatives were elucidated by spectral techniques. The minimum inhibitory concentrations (MIC) of the new benzoxazoles, along with those of previously synthesized analogues, were determined against standard bacterial and fungal strains and drug-resistant isolates, and compared with those of several reference drugs.
