The synthesis and antimicrobial activity of some 4-hydroxycoumarin derivatives.
Due to exceptional reactivity of 4-hydroxycoumarin, the synthesis of new coumarin derivatives of dimer and tetramer type has been carried out. The synthesis was carried out from 4-hydroxycoumarin and various aromatic aldehydes. In this way, compounds of the dimer 3,3'-(benzilidene)bis (4-hydroxycoumarin) type, as well as of the tetramer 3,3',3'',3'''-(1,4-dimethylenphenyl)tetra (4-hydroxycoumar...
متن کاملSynthesis and anti-cholinesterase activity of new 7-hydroxycoumarin derivatives.
A series of 7-hydroxycoumarin derivatives connected by an amidic linker to the different amines were designed and synthesized as cholinesterase inhibitors. Most compounds showed remarkable inhibitory activity against acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE). Among them, N-(1-benzylpiperidin-4-yl)acetamide derivative 4r with IC50 value of 1.6 μM was the most potent compound ...
متن کاملAntiviral activity of some hydroxycoumarin derivatives.
Esculetin (6,7-dihydroxycoumarin) and its diacetate exhibited a marked inhibitory effect on Newcastle disease virus replication in cell cultures at concentrations of 36 microM and 62 microM, respectively. These compounds were selected from ten hydroxycoumarin derivatives through an in vitro antiviral screen involving viruses of the picorna-, orthomyxo-, paramyxo-, and herpes virus families.
متن کاملAn efficient synthesis of α,α'-benzylidene bis(4-hydroxycoumarin) derivatives catalyzed by Tl2O3 nanoparticles
In this work, we attempted to synthesize thallium (III) oxide nano structures by direct thermal decomposition using thallium I phenylsuccinic acid coordination polymer [Tl(PsucH)]n as a precursor. Also, Tl2O3 nanoparticles have been characterized by scanning electron microscopy (SEM), X-Ray powder diffraction (XRD) and IR spectroscopy and then we report a simple and efficient method for the syn...
متن کاملSynthesis and Inhibiting Activity of Some 4-Hydroxycoumarin Derivatives on HIV-1 Protease
Six novel 4-hydroxycoumarin derivatives were rationally synthesized, verified, and characterized by molecular docking using crystal HIV-1 protease. Molecular docking studies predicted antiprotease activity of (7) and (10). The most significant functional groups, responsible for the interaction with HIV-1 protease by hydrogen bonds formation are pyran oxygen, atom, lactone carbonyl oxygen and on...
