Description

General description

Antitumor and anti-leukemic agent isolated from the bark of the yew tree. Promotes assembly of microtubules and inhibits tubulin disassembly. An effective agent in blocking HeLa and B16 cells at the G₂/M stage. Inhibits DNA synthesis and stimulates the release of tumor necrosis factor-α. Induces apoptosis in murine mammary carcinoma MCA-4 and ovarian carcinoma OCA-1 tumors.
