A series of novel bivalent securinine mimetics incorporating different linkers between C-15 and C-15′ were synthesized and their topoisomerase I (Topo I) inhibitory activities evaluated. It was thus revealed that mimetic R2 incorporating a rigid m-substituted benzene linker exhibits Topo I inhibitory activity three times that of parent securinine. Comprehensive structure-activity relationship analyses in combination with docking studies were used to rationalize the potent activity of these bivalent mimetics. Mechanistic studies served to confirm the deductions arising from docking studies that the active bivalent mimetics not only inhibited complexation between Topo I and DNA but also stabilized the Topo I-DNA complex itself.

Remote Enzyme-Coupled Amine Release

A remote enzyme-coupled amine release system has been developed in which biochemical and chemical "demasking" processes are sequentially linked via an enforced 1,3-diaxial disposition.Thus, pig liver esterase hydrolyzes an ester to an acid, and the acid promotes a fast intramolecular cleavage of an amide to an amine.The sequence has potential pharmacokinetic relevance because it allows enzyme-specific discharge of amine-based drugs following their trans-membrane journey as uncharged amides.
