Synthesis of Polyaminoalkyl Substituted Conjugates of Pyrrolo[2,1-c][1,4]benzodiazepine Involving SNAr Reaction of 2-Nitro-5-fluorobenzoate Precursors
摘要:
A synthetic procedure is described for conjugating polyaminoalkyl groups to the pyrrolo[2, 1-c][1,4]benzodiazepine pharmacophore in order to alter its characteristic DNA sequence binding preference. To this end SNAr reactions of 2-nitro-5-fluorobenzoate esters with different polyaminoalkyl side chains were examined and incorporated in the synthetic scheme.
