Deoxyviolacein is a bacterial metabolite and byproduct in the biosynthesis of the bisindole alkaloid violacein that has anticancer, antibacterial, and antifungal properties. It inhibits proliferation of hepatocellular carcinoma cells when used at concentrations ranging from 0.1 to 1 μM. Deoxyviolacein (125 μg/ml) has antibacterial activity against Gram-positive bacteria, including S. aureus, B. subtilis, and B. megaterium. It also has antifungal activity against R. solani when used at a concentration of 2 mg/ml. |

Australine is a pyrrolizidine alkaloid originally isolated fromC. australethat has enzyme inhibitory activities.1,2,3It is an inhibitor of glucoamylase (IC50= 5.8 μM) that also inhibits glucosidase I, sucrase, maltase, andA. nigerα-glucosidase (IC50s = 20, 28, 35, and 28 μM, respectively).2,3Australine is selective for these enzymes over glucosidase II, α- and β-mannosidase, and α- and β-galactosidase up to 500 μM, β-glucosidase, with only 5% inhibition at 66 μM, as well as isomaltase and trehalase (IC50= 97 and 160 μM, respectively). Australine (500 μg/ml) inhibits glycoprotein processing of viral glycoproteins in influenza virus-infected MDCK cells and induces the accumulation of glycoproteins.2
