Mogroside IV 是一种从罗汉果提取物中分离得到的三萜糖苷。它是非糖类甜味剂，甜度比蔗糖高。它具有抗氧化，抗糖尿病和抗癌作用。

CKD-711 是一种具备口服活性的氨基寡糖 α-葡萄糖苷酶 (α-glucosidase) 抑制剂，其IC50值为78 μg/mL。它对猪肠道的麦芽糖酶和蔗糖酶也表现出抑制作用，IC50值分别为2.5 μg/mL和0.5 μg/mL。CKD-711 对土生丛毛单胞菌 (Comamonas terrigena) 展示出选择性抗菌活性，可用于糖尿病等感染和代谢疾病的研究。

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 1.Molyneux, R.J., Benson, M., Wong, R.Y., et al.Australine, a novel pyrrolizidine alkaloid glucosidase inhibitor from Castanospermum australJ.
