Auristatins, synthetic analogues of the antineoplastic natural product Dolastatin10, are ultrapotent cytotoxic microtubule inhibitors that are clinically used as payloads in antibody–drug conjugates (ADCs). The design and synthesis of several new auristatin analogues with N-terminal modifications that include amino acids with α,α-disubstituted carbon atoms are described, including the discovery of

possible reason why B4 showed more potent inhibitory activities on sensitive tumor cells than lead A1. Western blotting analysis proved the target effects that B4 could suppress the expression of c-Myc and reduce H3K27 acetylation significantly. Liver microsomal metabolic stability assay and hERG channel inhibition evaluation illustrate compound B4 is metabolicstabilizable in human liver microsomes and
