  Novel anthracycline-spacer-β-glucuronide, -β-glucoside, and -β-galactoside prodrugs for application in selective chemotherapy

  摘要：

  A series of anthracycline prodrugs containing an immolative spacer was synthesized for application in selective chemotherapy. The prodrugs having the general structure anthracycline-spacer-beta-glycoside were designed to be activated by beta-glucuronidase or beta-galactosidase. Prodrugs with -chloro, bromo or -n-hexyl substituents on the spacer were synthesized as well as prodrugs containing a -beta-glucuronyl, -beta-glucosyl or -beta-galactosyl carbamate specifier. The key step in the synthesis of all prodrugs is the highly beta-diastereoselective addition reaction of the anomeric hydroxyl of a glycosyl donor to a spacer isocyanate resulting in the respective beta-glycosyl carbamate pro-moieties. The resulting protected pro-moieties were coupled to an anthracycline. Prodrugs were evaluated with respect to activation rate by the appropriate enzyme and additionally, their IC50 values were determined. Optimal prodrugs in this study were at least 100- to 200-fold less toxic than their corresponding drug in vitro and were activated to the parent drug in a half-life time of approximately 2 h.

  1-β-O-Glycopyranosyl carbamates are prepared with practically 100% β-diastereoselectivity from anomerically unprotected glycopyranosides and isocyanates. The isocyanates are prepared in situ from carboxylic acids via acyl azides.

  1-β-O-Glycopyranosyl carbamates 是通过在几乎 100% β-对映选择性下，从无保护的α-糖苷和异氰酸酯制备的。异氰酸酯则是由羧酸通过酰基叠氮化物原位制备得来的。
