Sulfonamide-containing linkage systems for drug conjugates

摘要

Sulfonamide-containing linkage systems for release of payload compounds from an attached targeting moiety in drug conjugates. The conjugates have the formula of [(P)-(L)]m-(T), wherein (P) is a payload compound, (L) is a linker, (T) is a targeting moiety and m is an integer from 1- to 10. Also provided are pharmaceutical compositions comprising such conjugates and there use in treating cancer.
