Coumarins, Xanthones and Related Compounds.
It has long been known that coumarins (α-pyrones) and xanthones (γ-pyrones) together form a large class of naturally occurring compounds exhibiting a wide range of biological activities. However, the interest of the scientific community for these secondary metabolites, as well as for their structural analogues, has never decreased since these “old compounds” are constantly generating promising—...

متن کاملStudies on coumarins and coumarin-related compounds to determine their therapeutic role in the treatment of cancer.
The Benzopyrones are a group of compounds whose members include coumarins and flavonoids. Dietary exposure to benzopyrones is quite significant, as these compounds are found in vegetables, fruit, seeds, nuts, coffee, tea and wine. It is estimated that the average western diet contains approximately 1 g/day of mixed benzopyrones. It is, therefore, not difficult to see why extensive research into...
متن کاملPromoted Preparation of Aminophosphonate and Functionalized Coumarins Derivatives as Key Constituent of Many Pharmaceutical Compounds
The reaction between trialkyl phosphites with dialkyl actylenedicarboxylates in the presence of 2-hydroxyquinoline (2-quinolinol) leads to β-aminophsphonates derivatives which they have many applications in medicinal chemistry. When the reaction was performed by triphenylphosphite, a new pyrano quinoline compounds were obtained in fairly good yields. These compounds also ...
متن کاملPolyprenylated Phloroglucinols and Xanthones
Guttiferae (Clusiaceae) is a family of plants that includes more than 37 genera and 1600 species [1].
