Crystal structure of 2-(adamantan-1-yl)-5-(4-bromophenyl)-1,3,4-oxadiazole [PDF]

, 2014
In the title molecule, C18H19BrN2O, the benzene ring is inclined to the oxadiazole ring by 10.44 (8) . In the crystal, C—H interactions link the molecules in a head-to-tail fashion, forming chains extending along the c-axis direction.

Multifunctional Oxadiazole‐Based Polycatenars: A Pathway to Polar Columnar Phases

Advanced Materials Interfaces, EarlyView.
Aromatic core fluorination directs oxadiazole‐based polycatenars into ferroelectric and antiferroelectric columnar phases with supergelation and photo‐responsiveness. ABSTRACT Polar columnar liquid crystals (LCs) offer a promising pathway to nanostructured architectures for next‐generation ferroelectric devices.

Poly(1,3,4-oxadiazoles) via aromatic nucleophilic displacement [PDF]

, 1992
Poly(1,3,4-oxadiazoles) (POX) are prepared by the aromatic nucleophilic displacement reaction of di(hydroxyphenyl) 1,3,4-oxadiazole monomers with activated aromatic dihalides or activated aromatic dinitro compounds. The polymerizations are carried out in

Synthesis, Characterization, and Biological Evaluation of Aliphatic‐Substituted Benzimidazole Derivatives: Induction of Apoptosis, Cell Cycle Arrest, and Molecular Docking in Breast Cancer Cells

Drug Development Research, Volume 87, Issue 2, April 2026.
ABSTRACT A new series of aliphatic‐substituted benzimidazole derivatives was synthesized and structurally characterized to evaluate their potential anticancer activity. Among the synthesized compounds, compound 4 exhibited the most potent cytotoxic effects against MCF‐7 and MDA‐MB‐231 breast cancer cell lines, with IC₅₀ values comparable to those of ...

A survey of liquid crystalline oxadiazoles

, 2008
We propose a survey of those oxadiazole compounds, which are mesogenic. We will see that they can have bend-shaped molecules, a biaxial nematic phase, or other interesting peculiarities in the nematic and smectic phase.

In Silico, In Vitro, and In Vivo Antinociceptive Potential of S‐Naproxen Derivatives

ChemistryOpen, Volume 15, Issue 4, April 2026.
Selected naproxen derivatives were investigated for their antinociceptive effects, using in vitro (COX‐I/COX‐II antagonistic effect), in vivo (acetic acid and hot plate assay), and in silico (molecular simulation studies) approaches. The COX inhibition studies revealed that the maximum percent effect exhibited by GMO‐I‐111a 96.01 and 92% against COX‐2 ...
