Chemically Defined Antibody- and Small Molecule-Drug Conjugates for in Vivo Tumor Targeting Applications: A Comparative Analysis

J Am Chem Soc. 2018 Feb 7;140(5):1617-1621. doi: 10.1021/jacs.7b13361. Epub 2018 Jan 27.

Abstract

We present the first direct comparative evaluation of an antibody-drug conjugate and of a small molecule-drug conjugate for cancer therapy, using chemically defined products which bind with high-affinity to carbonic anhydrase IX, a marker of tumor hypoxia and of renal cell carcinoma.
