Method for preparing thioether conjugates

A method is provided for preparing thioether conjugates useful in treating neoplastic diseases and preferably formed of the BR96 immunoconjugate synthesized from a heterobifunctional linker of doxorubicin, wherein a purified and reduced form of BR96 MAb is conjugated with the 6-maleimidocaproyl hydr...

Zusammenfassung:A method is provided for preparing thioether conjugates useful in treating neoplastic diseases and preferably formed of the BR96 immunoconjugate synthesized from a heterobifunctional linker of doxorubicin, wherein a purified and reduced form of BR96 MAb is conjugated with the 6-maleimidocaproyl hydrazone of doxorubicin and the resulting crude conjugate is purified.
