We describe the rational design and synthesis of B- and A, B-ring-modified camptothecins. The key alpha-hydroxy-delta-lactone pharmacophore in 7-tert-butyldimethylsilyl-10-hydroxycamptothecin (DB-67, 14) displays superior stability in human blood when compared with clinically relevant camptothecin analogues. In human blood 14 displayed a t(1/2) of 130 min(More)
IGF-binding protein-3 (IGFBP-3) has both antiproliferative and proapoptotic effects on the growth of human breast cancer cells in vitro. However, the mechanisms governing these effects are not well understood. IGFBP-3 has been shown to associate with the cell surface through carboxyl-terminal residues. This suggests that it may interact with a specific cell(More)
