Abstract
A folate receptor targeted camptothecin prodrug was synthesized using a hydrophilic peptide spacer linked to folate via a releasable disulfide carbonate linker. The conjugate was found to possess high affinity for folate receptor-expressing cells and inhibited cell proliferation in human KB cells with an IC50 of 10 nM. Activity of the prodrug was completely blocked by excess folic acid, demonstrating receptor-mediated uptake.
