Abstract: | The water-soluble duocarmycin B1 prodrugs such as glycoside 3, phosphate 4 and carbamate 5 were synthesized for improving biological and pharmaceutical profiles of duocarmycin. Among these prodrugs, N-methylpiperazinylcarbamoyl derivative 5 exhibited potent antitumor activity against several human tumors in vivo. |
