Synthesis of a mitomycin C-lexitropsin hybrid

摘要

We have constructed hybrid drugs where mitomycin C is linked to the N-methylpyrrole carboxamide framework present in lexitropsins. The coupling reactions leading to these products are efficient and the yields are very high. An interesting spectroscopic feature of these hybrids is the red shift observed in the UV-vis spectrum. Although DFT calculations indicate the possible existence of complexes formed during the coupling reactions, these complexes were not detected. The only species produced and isolated were the mitomycin C-mono- and bis-N-methyl pyrrole conjugates. Published by Elsevier Masson SAS on behalf of Academie des sciences.
