Background: Antibody-directed enzyme prodrug therapy (ADEPT) is a promising new approach to deliver anticancer drugs selectively to tumor cells. In this approach, an enzyme is conjugated to a tumor-specific antibody. The antibody selectively localizes the enzyme to the tumor cell surface. Subsequent administration of a prodrug substrate of the enzyme leads(More)
Glucuronide derivatives of CBI-bearing CC-1065 analogues have been synthesized, and their cytotoxicities tested against U937 leukemia cells. The new compounds show potent antitumor activity in vitro. Compounds 1 and 2, and their corresponding glucuronides 3 and 4 have IC(50) values of 0.6, 0.1, 1.4 and 0.6 nM, respectively. Glucuronide 3 is approximately(More)
Background: The use of pretargeting technology for cancer imaging and treatment has made significant progress in the last few years. This approach takes advantage of the fact that biotin binds strongly to proteins avidin and streptavidin. Thus, a non-toxic tumor cell specific antibody is conjugated with avidin/streptavidin, and is administered to patients.(More)
