Deoxypodophyllotoxin (DPT) is a flavolignan that has been found in J. sabina and has diverse biological activities.1,2,3,4,5 It inhibits tubulin polymerization in a cell-free assay when used at a concentration of 50 nM.1 DPT in also inhibits COX-2 and 5-lipoxygenase (5-LO) in isolated mouse bone marrow-derived mast cells stimulated with KL, IL-10, and LPS (IC50s = 1.89 and 0.37 ?M, respectively).2 It reduces viral yield in the supernatant of MRC-5 cells infected with herpes simplex virus 1 (HSV-1) or HSV-2 when used at a concentration of 0.02 ?g/ml.3 DPT inhibits aggregation of rabbit platelets induced by platelet-activating factor (PAF), collagen, or arachidonic acid in a concentration-dependent manner.4 It induces mortality in P. rapae fifth instar larvae (LC50 = 0.02 g/L).5 DPT (70 ?g/kg) reduces tumor growth in a CT26 murine colon cancer model.1
