Rearranged (4 -> 2)-abeo-clerodane and clerodane diterpenes from Aristolochia chamissonis
(Elsevier B.V., 1999-02-01)
From stems of Aristolochia chamissonis Duch., five new diterpenes, one rearranged (4 --> 2)-abeo-clerodane and four ent-clerodanes, were isolated. Their structures were determined to be (+)-(4 --> 2)-abeo-kolavelool-3-oic ...

Clerodane diterpenes from leaves of Casearia sylvestris swartz
(2007-09-01)
Ethanolic extracts of the leaves of Casearia sylvestris yielded a novel clerodane diterpene, 15-hydroxy-3-cleroden-2-one, together with the known diterpenes (-)-hardwickiic acid, reported for the first time from this ...

Synergism between Terbinafine and a Neo-clerodane Dimer or a Monomer Isolated from Baccharis flabellata against Trichophyton rubrum
(Natural Products, 2019-01)
The new neo-clerodane dimer (DACD) likely formed by a [4+2] photo-cycloaddition between two molecules of ent-15,16-epoxy-19-hydroxy-1,3,13(16),14-clerodatetraen-18-oic acid (DAC), both isolated from Baccharis flabellata ...
Acetylated DNA-damaging clerodane diterpenes from Casearia sylvestris
(Elsevier B.V., 1998-11-01)
In addition to the known diterpene casearin G (1), two new clerodane diterpene casearins type, casearin S (2) and casearin T (3), were isolated from an acetylated bioactive CH2Cl2/MeOH extract from leaves of Casealia ...
Clerodane diterpenes from Aristolochia species
(1987-12-01)
The investigation of Aristolochia brasiliensis and A. esperanzae afforded 12 clerodane derivatives, including the following six novel ones: rel (5S, 8R, 9S, 10R)-2-oxo-ent-3-cleroden-15-oic acid, rel (5S, 8R, 9S, ...
