Synthesis and antifungal activities of 5/6-arylamino-4,7-dioxobenzothiazoles

Microwave-assisted preparation of graphene quantum dots immobilized nanosilica as an efficient heterogeneous nanocatalyst for the synthesis of xanthenes

“…Xanthenes are very important oxygen-containing heterocyclic compounds because of their wide applications in pharmacy as antiviral, anticancer, antibacterial and etc. 29,[34][35][36][37] Results showed that the products were efficiently prepared in the presence of the freshly prepared heterogeneous catalyst under green reaction conditions and the catalyst was separated very simply filtration. In addition, recyclability and reusability of the catalyst were studied.…”

Highly Active Small Aminated Quinolinequinones against Drug-Resistant Staphylococcus aureus and Candida albicans

“…A literature survey on the rational design of antimicrobial agents highlights the importance of the bicyclic heterocyclic quinones [25,42]. From earlier studies, the presence and position of the heteroatom such as nitrogen, sulfur, or oxygen in the ring system have been found to be very important for the activity [43][44][45]. Among a considerable number of those molecules in the literature, such as cribostatin I [46], streptonigrin [47,48], and lavendamycin [49], we have particularly focused on the most important 1,4-quinone fused with C3X ring system where X is a nitrogen atom, named quinolinequinones (QQs).…”

An Efficient Electrochemical Method for the Synthesis of Quinoxaline-dione Derivatives from Oxidation of Catechols in the Presence ofN1,N2-dibenzylethane-1,2-diamine

“…Heterocyclic quinones containing a nitrogen atom are known to possess antibacterial [11][12][13] antifungalous, [14][15][16] antioxidant, 17 anticarcinogenic 18,19 and cytotoxic activities. 20,21 Quinoxaline derivatives are nitrogen-containing heterocyclic compounds, and their importance has been reported in the literature.…”
