In last few decades, nitrogen‐containing heterocycles have maintained their status as an
important core of FDA‐approved drugs and medicinally active compounds. Quinoxaline is …

BACKGROUND Continuous use of synthetic bactericides and fungicides is causing
pathogens to develop resistance, resulting in increased use of pesticides and affecting food …

A series of novel chalcone derivatives containing pyrazole oxime ethers were designed and
synthesized. The structures of all the target compounds were determined by NMR and …

An efficient and environmentally friendly method was established for designing novel 3-
amino-1, 4-dihydroquinoxaline-2-carbonitrile (1) via the reaction of bromomalononitrile and …

In this study, 24 chalcone derivatives containing benzoxazole were designed and
synthesized, and the structures of all target compounds were confirmed by NMR and HRMS …

In this study, 24 chalcone derivatives containing indole were designed and synthesized.
Some of the target compounds exhibited significant antiviral and antibacterial effects. The …

Functionalized polysubstituted quinoxalines have been widely reported to possess
appealing biological activities of great pharmaceutical importance, which drew researchers …

A series of myricetin derivatives containing isoxazole were designed and synthesized. All
the synthesized compounds were characterized by NMR and HRMS. In terms of antifungal …

In this paper, a series of derivatives were synthesized by introducing the pharmacophore
pyrazole ring and piperazine ring into the structure of the natural product myricetin through …

A series of chalcone derivatives containing 1, 2, 4-triazolo-[3, 4-b]-1, 3, 4-thiadiazole was
designed and synthesized. Structures of all compounds were characterized by 1H NMR …
