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.

It is intended to provide novel amine compounds which are efficacious against diseases such as infection with HIV virus, rheumatism and cancer metastasis. Namely, amine compounds represented by the following general formula (1):In a typical case, A1 and A2 represent each an optionally substituted monocyclic or polycyclic aromatic heterocycle; W represents cyclic C3-10 alkylene, an optionally substituted monocyclic or polycyclic aromatic heterocycle, a monocyclic or polycyclic aromatic ring or a partly saturated polycyclic aromatic ring; X represents O, CH2, C(=O) or NR11; and D is a group represented by the following general formula (4) or (6).-Q-Y-BIn the formula (6), Q represents a single bond, S, O or NR12; and Y is a group represented by the following general formula (7). z represents an optionally substituted monocyclic or polycyclic aromatic ring. In the formula (6), B represents NR25R26. In the above formulae, R1 to R26 each represents hydrogen, alkyl, alkenyl or alkynyl.
