Abstract

The present invention provides novel cryptophycin compounds having the following structure: ##STR1## The present invention also provides methods for producing cryptophycins from the Nostoc sp. of blue-green algae (cyanobacteria). Pharmaceutical compositions comprising novel cryptophycins are also provided by the present invention, as are methods for using cryptophycins to inhibit the proliferation of hyperproliferative cells. The present invention further provides methods for using cryptophycins to inhibit the proliferation of hyperproliferative cells with drug resistant phenotypes, and to treat pathological conditions, such as neoplasia.
