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 ...

2-Phenyl-5-(p-tolyl)-1,3,4-oxadiazole [PDF]

Acta Crystallographica Section E Structure Reports Online, 2011
The title compound, C(15)H(12)N(2)O, adopts the expected near-planar geometry, the phenyl and tolyl rings being inclined relative to the oxadiazole ring by 3.8 (3) and 8.3 (2)°, respectively. This allows adjacent mol-ecules to pack in a parallel fashion and form stacking along [010] via π-π inter-actions [centroid-centroid distances = 3.629 (2) and 3 ...

Radical Retrosynthesis of Natural Products Enabled by Iron‐Based Reductive Olefin Coupling

Angewandte Chemie Novit, Volume 2, Issue 1, March 2026.
This review highlights iron‐catalyzed reductive olefin coupling (ROC)—a strategy for C─C bond formation driven by metal‐hydride hydrogen atom transfer (MHAT)—as a key tool in natural products synthesis. This review surveys dozens of total syntheses employing ROC‐based strategies, highlighting its power to forge strained rings, quaternary centers, and ...
