Spiroheptadiene Reagents to React with Maleimide to Modify Antibodies
N6-[(Spiro[2.4]hept-4,6-dien-1-ylmethoxy)carbonyl]-L-lysine (1) enables the site-specific modification of proteins, making it useful for the preparation of homogeneous antibody-drug conjugates (ADCs).1) The spiroheptadiene (SCp) moiety of 1, introduced into a specific site of the protein by genetic code expansion, reacts with the maleimide moiety at a rate of 1.8-5.4 M-1 s-1 with the Diels-Alder reaction to form a 6-membered ring.2) ADCs obtained by reacting 1-incorporated antibodies with drug-conjugated maleimides exhibit better stability and efficacy than cysteine-maleimide conjugates both in mouse serum and in vivo.
We also offer 4-nitrophenyl spiro[2.4]hepta-4,6-dien-1-ylmethyl carbonate (2) as a reagent to introduce SCp moiety.
