Figure 1From: Selective cytotoxicity of Pancratistatin-related natural Amaryllidaceae alkaloids: evaluation of the activity of two new compoundsChemical structure of native Pancratistatin (A) and of Amaryllidaceae alkaloids AMD4 and AMD5 (B). The phenanthridone skeleton is a conserved feature in alkaloids of the Amaryllidaceae family. The Amaryllidaceae compounds have a methoxy group that varies in orientation between AMD4 (α) and AMD5 (β).Back to article page
