Genus Anthemis of Family Asteraceae contains mainly flavonoids, sesquiterpene lactones belonging to germacranolides, eudesmanolides, guaianolides, sterols and essential oils. The Plants of genus Anthemis have been known to have anti-inflammatory, hepatoprotective and antioxidant activities due to their rich contents of important physiological and biological compounds. They are referred to as nature's biological response modifier's and are involved in energy transfer, photosensitization and morphogenesis. Several clinical studies have shown that people who take diets rich in flavonoids and sesquiterpenes have reduced risk of developing cancer and cardiovascular diseases. This article covers most of constituents of plants of genus Anthemis reported from 2002 up to 2018. Furthermore, the biological activities of plants of genus Anthemis will be presented.

“…However, at the outset of our studies the allylation method outlined in Scheme to give such systems containing diverse β-hydroxymethyl substitution 5 had not been examined, aside from the work of Liu and co-workers to additionally γ-substituted adducts involving alkyne-derived molybdenum– or tungsten−π-allyl intermediates ( 4 , M = MoL n or WL n , X = alkyl). , This substitution pattern is present in several sesquiterpene lactones (e.g., Figure ), and the method could be of direct utility in syntheses of anthepseudolide ( 1 ) and the antibacterial hydroxyanthecotulide ( 2 ) and analogues . We also viewed alcohols 5 as potentially versatile substrates for conjugate addition and isomerization chemistry, which could lead to other bioactive natural product classes (see later).…”

Stereoselective Synthesis of β-(Hydroxymethylaryl/alkyl)-α-methylene-γ-butyrolactones

2011

View full text Add to dashboard Cite

Zinc or a chromium(II) source with 3-(bromomethyl)furan-2(5H)-one (3) and an aldehyde gives β-(hydroxymethylaryl/alkyl)-α-methylene-γ-butyrolactones 5 in good yields and high diastereoselectivities. The methodology is demonstrated in concise syntheses of (±)-hydroxymatairesinol (8) and (±)-methylenolactocin (10) by subsequent arylboronate conjugate addition and translactonization, respectively.

“…In Serbia nine species are known . Three main classes of compounds of chemosystematic interest, such as polyacetylenes, flavonoids, and sesquiterpene lactones, typical for Anthemidae, have been detected in the genus Anthemis . , Among the sesquiterpene lactones, only three types, that is, germacranolides (and seco -germacranolides), − eudesmanolides, , and guaianolides, ,,, have been isolated from the genus. The exception is an allergenic lactone with unusual structure (anthecotuloide), the constituent of A. cotula . , Continuing our chemotaxonomic examinations of the Yugoslavian flora belonging to Asteraceae and our search for new compounds of pharmacological interest, we now report the investigation of the aerial parts of Anthemis carpatica Willd, a species usually occurring at elevated, shady and grassy, sandy terrains of the Balkan Penninsula, eastern Alps, and east Carpathian Mountains…”
