Lignans

Schisandrin C (Wuweizisu-C) is a phytochemical lignan isolated from Schizandra chinensis Baill; shows anticancer-effects in human leukemia U937 cells.

Oxygen-heterocyclic compound

(+)-Lariciresinol is a lignan, a type of polyphenolic compound, which is primarily derived from plant sources such as flaxseeds, sesame seeds, and whole grains. As a naturally occurring compound in these plants, it plays a role in their defense mechanisms against pathogens.

(-)-Arctigenin is a lignan compound, which is naturally derived from certain plant species, primarily found in the seeds of Arctium lappa, commonly known as burdock. The compound exhibits a diverse mode of action, primarily noted for its ability to inhibit the proliferation of cancer cells through apoptosis induction, cell cycle arrest, and modulation of various signaling pathways. Additionally, it exerts antiviral effects by targeting viral replication processes and exhibits anti-inflammatory properties by downregulating pro-inflammatory cytokines.

4'-Demethylepipodophyllotoxin is a semisynthetic lignan, derived from the toxin podophyllotoxin, which is extracted from the roots and rhizomes of Podophyllum species, such as Podophyllum peltatum. The compound acts primarily as a topoisomerase II inhibitor. By binding to and stabilizing the enzyme-DNA complex, it prevents the re-ligation of DNA strands, which ultimately leads to breaks in the DNA and triggers apoptosis in rapidly dividing cancer cells.

(+)-Pinoresinol is a chiral lignan compound, which is primarily found in various plant sources such as flaxseed, sesame seeds, and olive oil. It plays a significant role in the plant's defense mechanisms by contributing to the formation of the plant cell wall and acting as an antioxidant.

(+/-)-Syringaresinol is a type of lignan, which is a category of polyphenolic compounds. It is primarily sourced from various plant materials, including seeds, roots, and barks of certain tree species. These naturally occurring compounds are integral to the plant's defense mechanisms and provide various ecological benefits.

4-Deoxypodophyllotoxin is a natural lignan, which is a type of secondary metabolite. It is primarily sourced from the roots and rhizomes of several plants belonging to the Podophyllum species, such as Podophyllum hexandrum. This compound exhibits its mode of action by interfering with microtubule assembly, thus disrupting cell division and leading to apoptotic cell death. Its effectiveness at halting mitosis makes it a subject of interest in cancer research.

Fargesin is a naturally occurring compound that is a bioactive constituent of Magnolia flowers. It is derived from the dried buds of Magnolia fargesii, a plant traditionally used in herbal medicine. The compound exhibits a mode of action that involves anti-inflammatory and anti-allergic properties. It operates through the inhibition of the release of pro-inflammatory mediators, thereby reducing inflammation and allergic responses.
