Secoisolariciresinol

1,4-Butanediol, 2,3-bis((4-hydroxy-3-methoxyphenyl)methyl)-, (R-(R*,R*))-

C20H26O6 (362.1729)


Secoisolariciresinol, also known as knotolan or secoisolariciresinol, (r*,s*)-isomer, is a member of the class of compounds known as dibenzylbutanediol lignans. Dibenzylbutanediol lignans are lignan compounds containing a 2,3-dibenzylbutane-1,4-diol moiety. Secoisolariciresinol is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Secoisolariciresinol can be found in a number of food items such as grape, saskatoon berry, asparagus, and sweet potato, which makes secoisolariciresinol a potential biomarker for the consumption of these food products. Secoisolariciresinol can be found primarily in urine. Secoisolariciresinol is a lignan, a type of phenylpropanoid. It is present in the water extract of silver fir wood, where its content is more than 5 \\\\% . (-)-secoisolariciresinol is an enantiomer of secoisolariciresinol having (-)-(2R,3R)-configuration. It has a role as an antidepressant, a plant metabolite and a phytoestrogen. It is an enantiomer of a (+)-secoisolariciresinol. Secoisolariciresinol has been used in trials studying the prevention of Breast Cancer. Secoisolariciresinol is a natural product found in Fitzroya cupressoides, Crossosoma bigelovii, and other organisms with data available.

Matairesinol

(3R,4R)-Dihydro-3,4-bis[(4-hydroxy-3-methoxyphenyl)methyl]-2(3H)-furanone; (-)-Matairesinol; (8R,8R)-(-)-Matairesinol

C20H22O6 (358.1416)


Matairesinol belongs to the class of organic compounds known as dibenzylbutyrolactone lignans. These are lignan compounds containing a 3,4-dibenzyloxolan-2-one moiety. Matairesinol is an extremely weak basic (essentially neutral) compound (based on its pKa). Outside of the human body, matairesinol is found, on average, in the highest concentration in a few different foods such as sesame, burdocks, and flaxseeds, and in a lower concentration in oats, asparagus, and poppies. Matairesinol has also been detected, but not quantified in, several different foods, such as silver lindens, tamarinds, cherry tomato, skunk currants, and fireweeds. This could make matairesinol a potential biomarker for the consumption of these foods. Matairesinol is composed of gamma-butyrolactone in which the 3 and 4 positions are substituted by 4-hydroxy-3-methoxybenzyl groups (the 3R,4R-diastereomer). (-)-matairesinol is a lignan that is gamma-butyrolactone in which the 3 and 4 positions are substituted by 4-hydroxy-3-methoxybenzyl groups (the 3R,4R-diastereomer). It has a role as a phytoestrogen, a plant metabolite, an angiogenesis inhibitor and an anti-asthmatic agent. It is a polyphenol, a lignan and a gamma-lactone. Matairesinol is a natural product found in Crossosoma bigelovii, Brassica oleracea var. sabauda, and other organisms with data available. See also: Arctium lappa fruit (part of); Pumpkin Seed (part of). Matairesinol is a plant lignan. It occurs with secoisolariciresinol in numerous foods such as oil seeds, whole grains, vegetables, and fruits. (-)-Matairesinol is found in many foods, some of which are caraway, pecan nut, cereals and cereal products, and longan. A lignan that is gamma-butyrolactone in which the 3 and 4 positions are substituted by 4-hydroxy-3-methoxybenzyl groups (the 3R,4R-diastereomer). Matairesinol confers anti-allergic effects in an allergic dermatitis mouse model. DfE-induced changes in IL-4 and IFN-γ mRNA expression in the ears of NC/Nga mice were reversed by matairesinol application[1].
