Synthesis of some tetrazole fused pyrido[2,3-c]coumarin derivatives from a one-pot three-component reaction via intramolecular 1,3-dipolar cycloaddition reaction of azide to nitriles

Synthesis and Characterization of Some New Coumarins with in Vitro Antitumor and Antioxidant Activity and High Protective Effects against DNA Damage

“…Coumarins are an important class of compounds of both natural and synthetic origin. Many compounds which contain the coumarin moiety exhibit useful and diverse pharmaceutical and biological activities, often depending on the substituents they bear in the parent benzopyran moiety [1,2] and, there has been a growing interest in their synthesis [3]. Some of these coumarin derivatives have been found useful in photochemotherapy, antitumor [4], anti-HIV therapy [5,6], as CNS-stimulants [7], antibacterial [8,9,10], anticoagulants [11,12,13], antifungal [14,15], antioxidant [16] agents and as dyes [17].…”

Synthesis of some novel quinazolin‐4(3H)‐one hybrid molecules as potent urease inhibitors

“…In 1820, coumarin was first obtained as a natural product and nearby 150 species of coumarin were found in 30 diverse plant families like Umbelliferae, Oleaceae, Clusiaceae, Guttiferae, Rutaceae. Coumarin is widely used as a pharmacophore in medicinal chemistry . Moreover, coumarin and its derivatives show rare side effects on human body .…”
