Atrasentan, also known as ABT-627, is a orally available ETA receptor antagonist with potential antineoplastic activity. As a selective antagonist of the endothelin-A (ETA) receptor, atrasentan binds selectively to the ETA receptor, which may result in inhibition of endothelin-induced angiogenesis and tumor cell proliferation.
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.
