Populin is a glucoside occurring in the bark, buds and leaves of certain species of poplar.

Z-N-desmethyldoxepin is an active metabolite of doxepin, a tricyclic antidepressant. Z-N-desmethyldoxepin appeared to be a terminal oxidative metabolite, in comparison with isomeric form E-N-desmethyl-doxepin, which is undergone further oxidation under the action of CYP2D6 activity.

ASARININ, (+)- ((+)-episesamin), an abundant lignan in sesame seed, has been identified as an active principle in an aqueous extract of Lindera obtusiloba (Japanese Spicebush) with a strong anti-inflammatory potential. (+)-episesamin (ES) is known to block the TNF-α-induced mitogenic VSMC response. Protective effect of (+)-episesamin against PDGF-BB-induced activation of vascular smooth muscle cells is mediated by induction of haem oxygenase-1 and inhibition of mitogenic signalling. ES interferes with inflammation-associated VSMC activation and subsequent decreased proliferation and migration due to anti-oxidative properties and impaired activation of NF-ĸB, known contributors to atherogenesis. These results suggest ES as a complemental treatment of VSMC specific vascular diseases such as atherosclerosis. (+)-Episesamin inhibits adipogenesis and exerts anti-inflammatory effects in 3T3-L1 (pre)adipocytes by sustained Wnt signaling, down-regulation of PPARγ and induction of iNOS. (+)-episesamin seems to be the active drug in the L. obtusiloba extract being responsible for the inhibition of adipogenesis and, thus, should be evaluated as a novel potential complementary treatment for obesity.

Ent-atorvastatin (3S,5S-atorvastatin) is impurity and inactive enantiomer of lipid-lowering agent Atorvastatin.

Fluvastatin Anti-Isomer is a metabolite of lipid-lowering agent Fluvastatin. Fluvastatin is very unstable during storage and anti-isomer as well as lactones are the main formed by-products.

Neochlorogenic acid is a natural polyphenolic compound which can be found in a variety of plant sources and especially some types of dried fruit. It is an epimer of chlorogenic acid. Neochlorogenic has been investigated as a chemopreventative dietary compound for breast cancer and collorectal cancer. It has in-vitro anti-inflammatory properties, and may be responsible for the laxative effect fo prunes. Research surrounding neochlorgenic acid has often involved various plant extracts, rather than pure preparations of the compound.

4-p-coumaroylquinic acid is one of the most abundant components of Turkish black tea Camellia sinensis L possesses antioxidant properties.

Cryptochlorogenic acid is a structural isomer of chlorogenic acid; it is a cinnamate ester formed by the condensation of the carboxy group of trans-caffeic acid with the 4-hydroxy group of quinic acid. It can be isolated from several plant sources including apples, coffee, sunflowers, potatoes, and Hibiscus sabdariffa. Cryptochlorogenic acid mixed with related compounds has demonstrated potential anti-oxidant and anti-inflammatory properties and shown inhibitory activity against HBV DNA replication.
