Abstract
In search for a novel chemotype to develop topoisomerase I (Top1) inhibitors, the pyrazolo[1,5-a]quinazoline nucleus, structurally related to the indenoisoquinoline system precursor of well-known Top1 poisons, was variously decorated (i.e., a substituted phenyl ring at 2- or 3-position, a protonable side chain at 4- or 5-position), affording a number of Top1 inhibitors with cleavage patterns common to CPT and MJ-III-65. SARs data were rationalized by means of an advanced docking protocol.Entities:
