- Coumarin is a
chemical compound (benzopyrone); a toxin found in many plants, notably
in high concentration in the tonka bean, vanilla grass, woodruff,
mullein, and bison grass.
- Coumarin has
blood-thinning, anti-fungicidal and anti-tumor activities.
- The biosynthesis of
coumarin in plants is via hydroxylation, glycolysis and cyclization of
cinnamic acid.
- Coumarin can
be prepared in a laboratory in a Perkin reaction between salicylaldehyde
and acetic anhydride.
- The air-dried stem
and root barks of Galipea trifololiata contain a third previously
unreported coumarin identified as 7-isopentenyloxy.
- coumarin-4-acetic
acids 1-3 using method common for peptide synthesis6 .
- Reaction of
coumarin-4-acetic acid with -hydroxy succinimide in the presence
of di cyclo hexyl carbo diimide gave NHS ester, which was coupled
with linker moiety to give protected product in yield 57-75% after
chromatography.
- Coumarin derivatives
(dicumarol, ethyl biscoumacetate, and warfarin) are oral anticoagulants,
as are the indandione derivatives.
- Use of any of these
agents during pregnancy may result in significant problems for the fetus
and newborn.
- Micelles formed by
an amphiphilic diblock copolymer composed of PEO and PCMA are electro
chemically active in aqueous electrolyte solution, displaying an
irreversible oxidation process of coumarin at a potential of about 1.75
V.
- The host–guest
complex of C-methyl resorcin arene with coumarin and thiocoumarin has
been characterized by single crystal X-ray diffraction
technique.
- Coumarin-3-carboxylic acid and CA anions in free
space produce broad emissions centered at 438 nm when excited by
337.1-nm UV light.
- Ultra fast photo
induced electron transfer in coumarin 343 sensitized TiO2-colloidal
solution.
- New orange
fluorescent dyes based on coumarin, which has high fluorescence yield
and chemical stability, have been synthesized.
- It has a sweet
scent, readily recognised as the scent of newly-mown hay, and has been
used in perfumes.
- It has clinical
medical value as the precursor for several anticoagulants, notably
warfarin, and is used as a gain medium in some dye lasers.
- Coumarin has been
used in the treatment of lymphedema.
- This medication is a
blood thinner used to keep blood flowing smoothly and prevent the
formation of blood clots.
- Coumarin is also
used formedicinal purposes to treat oedemas.
