4-Aza-2,3-dehydro-4-deoxypodophyllotoxin analogues 3a-n were synthesized through quinolines 2a-n. Comparison of their cytotoxicity against P-388 leukemia cells revealed that the steric effects of the ring B substituents on the activity are greater than the electronic effects, while the presence of a

The cytotoxic activity of methanol extracts of leaves collected from 39 seashore plants in Iriomote Island, subtropical Japan was examined on human leukaemia cells (K562 cells) using a flow cytometer with two fluorescent probes, ethidium bromide and annexin V-FITC. Five extracts (10 microg/mL) from

BACKGROUND
The demand for podophyllotoxin and deoxypodophyllotoxin is still increasing and commercially exploitable sources are few and one of them, Podophyllum hexandrum Royle (Berberidaceae), is a "critically endangered" species.
OBJECTIVE
The first aim was to quantify the amount of
Isolation of apoptosis- and differentiation-inducing substances toward human promyelocytic leukemia HL-60 cells from leaves of Juniperus taxifolia.

A chloroform extract of the leaves of Juniperas taxifolia exhibited a marked antiproliferative effect on human promyelocytic leukemia HL-60 cells at a concentration of 2.5 microg/ml. Deoxypodophyllotoxin (4) was identified in the extract as an outstanding antiproliferative compound, and five

28 cyclolignans, most of them derived from podophyllotoxin, have been evaluated for their antineoplastic and antiviral activities. They were subjected to screening against P-388 murine leukemia, A-549 human lung carcinoma, and HT-29 colon carcinoma, while antiviral assays were performed on herpes

Nineteen cyclolignans of varied structures, most of them isolated from Juniperus sabina leaves, were evaluated for their antineoplastic and antiviral activities. They were subjected to screening against P-388 murine leukemia, A-549 human lung carcinoma, and HT-29 colon carcinoma, while the antiviral

The antitumour activity of a foliage extract of a New Zealand gymnosperm, Libocedrus plumosa, against P388 leukaemia cells was due to β-peltatin 3. Deoxypodophyllotoxin 1 and β-peltatin A-methyl ether 2, P388-active lignans previously reported in L. bidwillii, were found at lower levels. High levels
