Parallel synthesis of 9-aminoacridines and their evaluation against chloroquine-resistant Plasmodium falciparum
摘要:
A parallel synthetic strategy to the 9-aminoacridine scaffold of the classical anti-malarial drug quinacrine (2) is presented. The method features a new route to 9-chloroacridines that utilizes triflates of salicylic acid derivatives, which are commercially available in a variety of substitution patterns. The route allows ready variation of the two diversity elements present in this class of molecules: the tricyclic aromatic heterocyclic core, and the disubstituted diamine sidechain. In this study, a library of 175 compounds was designed, although only 93 of the final products had purities acceptable for screening. Impurity was generally due to incomplete removal of 9-acridones (18), a degradation product of the 9-chloroacridine synthetic intermediates. The library was screened against two strains of Plasmodium falciparum, including a model of the drug-resistant parasite, and six novel compounds were found to have IC50 values in the low nanomolar range.

The application provides macromolecule-supported compounds of Formula I or III comprising a macromolecular support linked by conjugation to one or more aminobenzazepine derivatives. The application also provides aminobenzazepine derivative intermediate compositions of Formula II comprising a reactive functional group. Such intermediate compositions are suitable substrates for formation of the macromolecule-supported compounds through a linker or linking moiety. The application further provides compositions comprising the macromolecule-supported compounds, as well as methods of treating cancer with the macromolecule-supported compounds.
