Antiproliferative activity of the non-myelotoxic antitumour agent of plant origin, Thaliblastine, on two human glioma cell lines.

The antiproliferative activity of the non-myelotoxic antitumour agent of plant origin, Thaliblastine, on two human glioma cell lines is described. Thaliblastine was added once one day following start of culture; proliferation was monitored over 7 days. The antiproliferative activity of Thaliblastine was strongly dependent on concentration and time of incubation. The ID50 of Thaliblastine in T406 and GW27 glioma lines was 5.1 micrograms/ml and 8.2 micrograms/ml (7.0 microM and 11.2 microM), respectively.
