Dendrobine is a sesquiterpenoid that has been found in D. nobile and has anticancer activity.1,2 It decreases viability of A549 cells when used at concentrations ranging from 2.5 to 15 ?g/ml.2 It induces apoptosis in A549 cells when used at concentrations ranging from 1 to 10 ?g/ml, as well as increases JNK phosphorylation and sensitizes A549 cells to cisplatin at 10 ?g/ml. Dendrobine (50 mg/kg per day) reduces tumor growth in an A549 mouse xenograft model with an additive effect when used in combination with cisplatin.
