Synthesis, antibacterial activity and in silico study of new bis(1,3,4-oxadiazoles)

Synthetic Communications, 2022
In the current study, new bis(2,5-disubstituted 1,3,4-oxadiazoles) linked to aliphatic cores were efficiently prepared. For this purpose, the appropriate bis(aldehydes) and benzohydrazides were reacted to produce the corresponding bis(N-benzoylhydrazones)

Perfluoro-1,3,4-oxadiazoles

Journal of Fluorine Chemistry, 1992
Abstract Some new polyfluorinated 1,3,4-oxadiazoles have been obtained via a two-step method. The cycloadditions of the 1,3,4-oxadiazoles have been studied and an analysis of the energies of the frontier orbitals calculated by the MNDO method indicates a LUMO-dependent pathway for cycloaddition.

Banana-Shaped 1,2,4-Oxadiazole Analogues of 1,3,4-Oxadiazoles

Molecular Crystals and Liquid Crystals Science and Technology. Section A. Molecular Crystals and Liquid Crystals, 2001
Abstract In the last years bent banana-shaped mesomorphic molecules found an increasingly great interest among theoreticians and experimentalists due to the nature of this type of liquid crystals to exhibit a spontaneous polarization in the absence of any chiral group in the molecules.

Bioisosterism: 1,2,4‐Oxadiazole Rings

ChemMedChem, 2023
AbstractAlthough studies in drug discovery have gained momentum in recent years, the conversion of drugs in use today into less toxic derivatives with pharmacologically superior properties is still of great importance in drug research. Bioisosterism facilitates the conversion of drugs into derivatives that present more positive pharmacological and ...

Synthesis and In Vitro and In Vivo Biological Activity Evaluation and Quantitative Proteome Profiling of Oxadiazoles Bearing Flexible Heterocyclic Patterns.

Journal of Agricultural and Food Chemistry, 2019
A novel series of simple 1,3,4-oxadiazoles that bear flexible heterocyclic patterns was prepared, and their biological activities in plant pathogenic bacteria, fungi, oomycetes, and Meloidogyne incognita in vitro and in vivo were screened to explore low ...
