O-methyltransferases of furanocoumarin biosynthesis

Archives of Biochemistry and Biophysics, 1978
Extracts of the furanocoumarin-synthesizing plants, Ruta graveolens L. and Heracleum lanatum Michx., contain a soluble O-methyltransferase system mediating the methylation of the 5- and 8-hydroxyls of linear furanocoumarins by S-adenosyl- l -methionine.

Three types of enzymes complete the furanocoumarins core skeleton biosynthesis in Angelica sinensis.

Phytochemistry
Furanocoumarins (FCs) are widely distributed secondary metabolites found in higher plants, including Apiaceae, Rutaceae, Moraceae, and Fabaceae. They play a crucial role in the physiological functions of plants and are well-known for their diverse ...

Furanocoumarins promote proteasomal degradation of viral HBx protein and down-regulate cccDNA transcription and replication of hepatitis B virus.

Virology
Nucleot(s)ide analogues, the current antiviral treatments against chronic hepatitis B (CHB) infection, are non-curative due to their inability to eliminate covalently closed circular DNA (cccDNA) from the infected hepatocytes.

An efficient synthesis of furanocoumarins

Tetrahedron, 1992
Abstract An efficient synthesis of linear and angular furanocoumarins has been carried out starting from iodoumbelliferone derivatives. First synthesis of 6-iodoumbelliferone is described. The average yields are higher than those reported before.

Inhibitory potential of furanocoumarins against cyclin dependent kinase 4 using integrated docking, molecular dynamics and ONIOM methods

Journal of Biomolecular Structure and Dynamics
Cyclin Dependent Kinase 4 (CDK4) is vital in the process of cell-cycle and serves as a G1 phase checkpoint in cell division. Selective antagonists of CDK4 which are in use as clinical chemotherapeutics cause various side-effects in patients ...
