The present invention is directed to novel cytotoxic tubulysin analogs and derivatives, to antibody drug conjugates thereof, and to methods for using the same to treat medical conditions including cancer.
The current disclosure provides binding polypeptides (e.g., antibodies), and targeting moiety conjugates thereof, comprising a site-specifically engineered glycan linkage within native or engineered glycans of the binding polypeptide. The current disclosure also provides nucleic acids encoding the antigen-binding polypeptides, recombinant expression vectors and host cells for making such antigen-binding polypeptides. Methods of using the antigen-binding polypeptides disclosed herein to treat disease are also provided.

Dolastatin10, a potent tubulin-targeting marine anticancer natural product, provided the basis for the development of six FDA-approved antibody–drug conjugates. Through the screening of cyanobacterial Caldora penicillata environmental DNA libraries and metagenome sequencing, we identified its biosynthetic gene cluster. Functional prediction of 10 enzymes encoded in the 39 kb cluster supports the dolastatin
