Synthesis and antioxidant activity of 1,3,4-oxadiazoles and their diacylhydrazine precursors derived from phenolic acids [PDF]
Eight 1,3,4-oxadiazole derivatives containing phenolic acid moieties (7a-h) and eight of their diacylhydrazine precursors (6a-h) were synthesized, characterized using spectroscopic methods and examined by scavenging of stable DPPH (2,2-diphenyl-1 ...

Difluoromethyl-1,3,4-oxadiazoles Are Selective, Mechanism-Based, and Essentially Irreversible Inhibitors of Histone Deacetylase 6. [PDF]
Histone deacetylase 6 (HDAC6) is an important drug target in oncological and non-oncological diseases. Most available HDAC6 inhibitors (HDAC6i) utilize hydroxamic acids as a zinc-binding group, which limits therapeutic opportunities due to its genotoxic ...

Batch Versus Flow Lithiation-Substitution of 1,3,4-Oxadiazoles: Exploitation of Unstable Intermediates Using Flow Chemistry [PDF]
1,3,4‐Oxadiazoles are a common motif in pharmaceutical chemistry, but few convenient methods for their modification exist. A fast, convenient, high yielding and general α‐substitution of 1,3,4‐oxadiazoles has been developed using a metalation ...

Antimicrobial Activity of 1,3,4-Oxadiazole Derivatives [PDF]
The worldwide development of antimicrobial resistance forces scientists to search for new compounds to which microbes would be sensitive. Many new structures contain the 1,3,4-oxadiazole ring, which have shown various antimicrobial activity, e.g., antibacterial, antitubercular, antifungal, antiprotozoal and antiviral. In many publications, the activity

Synthesis of 2-Isobutyl, 2-Isobutyl-5-aryl and 2-Isobutyl-5-thiol-1,3,4-Oxadiazoles [PDF]
In this paper the synthesis of some substituted 1,3,4-oxadiazoles from isobutyric acid was studied. The isobutyric acid was converted into the corresponding ethyl ester, which then treated with hydrazine hydrate in ethanol to give the acid hydrazide. The
