Semisynthesis and biological evaluation of abietane-type diterpenes. Revision of the structure of rosmaquinone.

30 Jul 2009 The new aromatic diterpenes 7beta-O-benzylrosmanol (3), 7beta-O-benzyl-11,12-di-O-methylrosmanol (4), and 7alpha-thiophenylcarnosic acid (5) have been obtained by partial synthesis from carnosol (1), an abundant natural diterpene present in Salvia ... Read more...

Antitermitic activities of abietane-type diterpenes from Taxodium distichum cones.

27 May 2009 Eight known abietane-type diterpenes were isolated from the weak acidic fraction of the n-hexane extract from cones of Taxodium distichum, one of the extant, living fossil conifers. They were identified as 6,7-dehydroroyleanone (1), taxodal (2), ... Read more...

[Synthesis of dihydroquinopymaric acid conjugates with amino acids]

29 Apr 2009 Synthesis of dihydroquinopymaric acid amides and their 2beta-succinyl and 2beta-phthalyl derivatives containing residues of amino acids was carried out for the first time. Antiviral properties of the compounds synthesized were ... Read more...
