Drimane Homochiral Semisynthesis: Pereniporin a,9-EPI-Warburganal and C-9 Nitrogenated Drimanes
Natural Product Letters, 1998Abstract Starting with 12-acetoxy-7,9(11)-drimadiene, prepared from methyl zamoranate, a major Halimium viscosum component, pereniporin A, 9-epi-warburganal and a precursor of C-9 nitrogenated drimanes were synthesized.

Cytotoxic Drimane Sesquiterpenoids Isolated from Perenniporia maackiae
Journal of Natural Products, 2018A chemical investigation of a basidiomycetes fungus, Perenniporia maackiae, led to the discovery of 12 drimane sesquiterpenoids, including seven new constituents (1-7). The elucidation of the structures was performed via interpreting extensive spectroscopic methods, including ECD calculations.

Synthesis of biologically active drimanes from (−)-sclareol
Tetrahedron Letters, 1994Abstract The enantiospecific synthesis of drimenyl acetate (8), a key intermediate in the synthesis of biologically active drimanes, and albicanyl acetate (14), potent fish antifeedant, from sclareol (1), are described. Also a short and efficient synthesis of polygodial (22), from albicanyl acetate (14), is shown.

9-Deoxy drimane sesquiterpenes from Canella winterana
Phytochemistry, 1990Abstract The stem bark of Canella winterana collected in Florida yielded three new drimane sesquiterpenes. Their structures were elucidated from their spectral data as: 9-deoxymuzigadial, 9-deoxyisomuzigadial and 3β-acetoxypolygodial. The first two compounds, which are double bond isomers, could only be separated from each other on silver nitrate ...

Anti-inflammatory drimane sesquiterpene lactones from an Aspergillus species
Bioorganic & Medicinal Chemistry, 2014IFN-γ inducible protein 10 (IP-10, CXCL10) is a 10 kDa chemokine, which is secreted from various cell types after exposure to pro-inflammatory stimuli. This chemokine is a ligand for the CXCR3 receptor and regulates immune responses by activating and recruiting leukocytes such as T cells, eosinophils, monocytes, and NK cells to sites of inflammation ...
