In contrast, the comparable tansines (DM1 or DM4), theirinotecans and their metabolites ADC developed with Illudins, Syn-illudins, or Acylfulvenes (SN38), the calicheamicins (17-DMAG), the pyrrolobenzo will deliver a dose of the associated toxin that is 40% of a diazepines (SJG-136), the duocarmycins (CC-1065), the known non-toxic dose (estimated at 28% of a toxic dose and acylfulvene compounds do not require a linker and can be only 12% of a lethal dose). Thus, ADCS developed with directly attached to a steroid or a peptide that will subse Illudins, Syn-illudins, and Acylfulvenes will have minimal quently function as an AM and direct the associated complex systemic toxicity as compared to current agents. Thirdly, to specific tumor cells. An acylfulvene is attached to either a these agents are stable down to a pH of 2.0.
