Glycosylated prodrugs, a preparation method therefor, and their use with tumor-specific immunoenzymatic conjugates for the treatment of cancer, are described. These anthracycline prodrugs have formula (I). ##STR1##
The invention relates to compound of the formula (I)
in which the substituents are as defined in the specification; in free base form or in acid addition salt form; to its preparation, to its use as medicament and to medicaments comprising it.
report a novel bioorthogonal reaction that hinges on a bridgehead alkene (BHA)-enabled inverse-electron-demand Diels–Alder (IEDDA) cycloaddition. Readilyaccessible from natural product β-caryophyllene, the strained BHA displays high reactivity toward the IEDDA reaction while maintaining excellent biocompatibility. The developed IEDDA reaction has been applied to in vitro protein labeling and pretargeted
