Novel antineoplastic amine-containing derivatives and methods for synthesizing such derivatives of anthracycline antibiotics are disclosed. The derivatives are useful to anthracycline antibiotic conjugates which retain substantial immunospecificity of the unconjugated antibody molecule. Using the conjugates, targeted delivery of the attached antibiotics is achieved in vivo. Such conjugates are thus therapeutically effective against a variety of neoplastic cellular disorders when administered in vivo. Methods for preparing the antibody conjugates and for use of the conjugates in vivo are also disclosed.

Amine derivatives of anthracycline antibodies

Novel antineoplastic amine-containing derivatives and methods for synthesizing such derivatives of anthracycline antibiotics are disclosed. The derivatives are useful to prepare site-selectively attached therapeutic antibody-anthracyline antibiotic conjugates which retain substantial immunospecificity of the unconjugated antibody molecule. Using the conjugates, targeted delivery of the attached antineoplastic amine derivatives of anthracycline antibiotics is achieved in vivo. Such conjugates are thus therapeutically effective against a variety of neoplastic cellular disorders when administered in vivo. Methods for preparing the antibody conjugates and for use of the conjugates in vivo are also disclosed.
