derivatives of camptothecin substituted norcantharimide was designed by mimic strategy. These compounds were synthesized in moderate yields by directly coupling CPT with N-amino acid norcantharimides. Their cytotoxicity to four human tumour cell lines (HepG2, BGC-803, SW480 and PANC-1) and normal human cell lines L-O2 and HIEC was evaluated. The synthesized CPT substituted norcantharimide analogs (3g

A series of phosphonodipeptide derivatives of norcantharidin (exo-7-oxabicyclo[2.2.1] heptane-2,3-dicarboxylic anhydride) were synthesized and their structures were confirmed by H-1 NMR, P-31 NMR, IR, MS and elemental analysis.
