drimane

Drimane is a bicyclic sesquiterpene. It is the parent structure of many natural products with various biological activity.

Nanangenine G is a drimane sesquiterpene that has been found inAspergillus.1It is cytotoxic to NS-1 mouse myeloma cells (IC50= 47 μg/ml). 1.Lacey, H.J., Gilchrist, C.L.M., Crombie, A., et al.Nanangenines: Drimane sesquiterpenoids as the dominant metabolite cohort of a novel Australian fungus, Aspergillus nanangensisBeilstein J.

Nanangenine B is a drimane sesquiterpene that has been found inAspergillus.1It is active againstB. subtilis(IC50= 62 μg ml) and cytotoxic to NS-1 mouse myeloma cells (IC50= 38 μg ml). 1.Lacey, H.J., Gilchrist, C.L.M., Crombie, A., et al.Nanangenines: Drimane sesquiterpenoids as the dominant metabolite cohort of a novel Australian fungus, Aspergillus nanangensisBeilstein J.

Nanangenine F is a drimane sesquiterpene fungal metabolite that has been found inA. nanangensis.1It is active againstB. subtilis(IC50= 78 μg/ml) and cytotoxic to NS-1, DU145, and MCF-7 cancer and NFF non-cancerous cells (IC50s = 49, 95, 49, and 84 μg/ml, respectively). 1.Lacey, H.J., Gilchrist, C.L.M., Crombie, A., et al.Nanangenines: Drimane sesquiterpenoids as the dominant metabolite cohort of a novel Australian fungus, Aspergillus nanangensisBeilstein J.

Isonanangenine B is a drimane sesquiterpene lactone that has been found in Aspergillus. It decreases survivin mRNA expression in a reporter assay when used at concentrations of 13.6, 18.42, and 26.31 µM. Isonanagenine B (18.42 µM) inhibits STAT3 and NF-κB binding to the survivin promoter in chromatin immunoprecipitation (ChIP) assays. It also induces apoptosis in COLO 320DM cells.
