A cytostatic drug (taxol) which does not inhibit monocyte phagocytosis.

Taxol is a new cytotoxic agent which arrests cell division in the G2 and the M phases, due to its unique property of inhibiting microtubule function by stabilization. In contrast to other microtubule antagonists except griseofulvin, taxol did not inhibit monocyte phagocytosis. It is suggested that lack of interference with the function of mature leukocytes may reduce the immunosuppression induced by a cytotoxic agent.
