Investigation of the printability of ethyl 2‐[4‐(1,3,4‐oxadiazol‐2(3H)‐thion‐5‐yl)phenylhydrazono]‐3‐oxobutyrate on coated and uncoated papers

Coloration Technology, EarlyView.
Abstract There is a growing demand in the printing industry for pigment‐based inks with excellent lightfastness and rub resistance qualities. In this work, a novel ink with the formulation ethyl 2‐[4‐(1,3,4‐oxadiazole‐2(3H)‐thione‐5‐yl)phenylhydrazono]‐3‐oxobutyrate (OXKT) was prepared as a pigment and its printability was investigated for use in ...

Synthesis of Alpha‐Acyloxy‐(1,2,5‐Oxadiazole‐2‐Oxide) Carboxamides via Passerini Multicomponent Reaction. Evaluation of Nitric Oxide‐Releasing and Anti‐Proliferative Properties

Journal of Heterocyclic Chemistry, Volume 62, Issue 10, Page 1285-1292, October 2025.
The Passerini multicomponent reaction was used to synthesize α‐acyloxy‐(1,2,5‐oxadiazole‐2‐oxide)carboxamides in good to excellent yields (67‐97%) under microwave heating. All compounds were able to release NO in solution, within the concentration range of 0.8–7.4 μM. Antiproliferative activity was investigated against LNCaP, MCF‐7, and SK‐MEL‐28 tumor
