Examples of the macrocyclic lactone compounds useful in the present invention include, but are not limited to, the LL-F28249.alpha.-.lambda. series of compounds, the 23-oxo or 23-imino derivative thereof, the avermectins, the 22,23-dihydro derivatives thereof and the milbemycins. Compositions comprising the macrocyclic lactone compounds and the chemotherapeutic agents are also described herein.
