Combined computational-experimental analyses explain and quantify the spermine-vectorized F14512's boosted potency as a topoII poison. We found that an optimized polyamine moiety boosts drug binding to the topoII/DNA cleavage complex, rather than to the DNA alone. These results provide new structural bases and key reference data for designing new human topoII poisons.

Abstract
Combined computational-experimental analyses explain and quantify the spermine-vectorized F14512's boosted potency as a topoII poison. We found that an optimized polyamine moiety boosts drug binding to the topoII/DNA cleavage complex, rather than to the DNA alone. These results provide new structural bases and key reference data for designing new human topoII poisons.
