spdb-dm4

SPDB-DM4 is a drug-linker conjugate designed for antibody-drug conjugate (ADC) applications, employing the maytansine-based payload DM4 (a tubulin inhibitor) connected through a SPDB linker. This compound demonstrates significant anti-tumor efficacy.

Lys-Nε-SPDB-DM4 is a drug-linker conjugate that integrates the tubulin inhibitor DM4 with the linker Lys-Nε-SPDB, enabling the formation of an antibody-drug conjugate (ADC).

Sulfo-SPDB-DM4 is a drug-linker conjugate designed for antibody-drug conjugates (ADCs) that employs the maytansine-based payload (DM4, an antitubulin agent) connected through the sulfo-SPDB linker.

SPDB-DM4 is a part of the ADC. It is composed of DM1 (a microtubule inhibitor, also an antibody-encodable aristolochic acid alkaloid, used to overcome the systemic toxicity associated with aristolochic acid and enhance tumor-specific delivery) and SPDB, and exhibits highly efficient anti-tumor activity.

SPDB is a degradable ADC linker that can be used to synthesize antibody-drug conjugates. SPDB is a small fragment attached to the DM4 conjugate and conjugated to the antibody using a disulfide bond.
