General description
5,7-dimethoxycoumarin is isolated and identified from leaves and fruits of Pelea anisata H. Mann, a plant whose fruit are used in the construction of mohikana leis. It induces frameshift mutagenesis in bacteria. It also causes lethal photosensitization and the formation of sister chromatid exchanges in Chinese hamster cells.
Biochem/physiol Actions
5,7-Dimethoxycoumarin induces the processes of differentiation and melanogenesis in murine (B16) and human (A375).

In the present study we investigated the antiproliferative activity of 5,7-dimethoxycoumarin on the murine B16 and human A375 melanoma cell lines. The inhibitory concentration 50 (IC50) was estimated for each cell line by preliminary assay of tetrazolium salt reduction (MTT).

Malignant melanoma (melanoma malignum) is one of the most dangerous types of tumor. It is very difficult to cure. In recent years, a lot of attention has been given to chemoprevention. This method uses natural and synthetic compounds to interfere

Generally on the gas chromatogram of a volatile essential oil, terpenes, oxygenated compounds and sesquiterpenes appear. With temperature programming, it was shown that some non-volatiles are present with the volatiles. They are simple coumarin (2H-1-benzopyran-2-one) derivatives such as citropten (5,7-dimethoxycoumarin)

We have investigated the structure-activity relationship between 63 natural oxycoumarin derivatives and their effects on the expression of inducible-nitric oxide synthase (iNOS) induced by lipopolysaccharide. The protein expression of iNOS was screened by Western blot analysis, and four 5,7-dimethoxycoumarins were
