Malaria remains a significant infectious disease with even artemisinin-based therapies now facing resistance in the field. Development of new therapies is urgently needed, either by finding new compounds with unique modes of action, or by reversing resistance towards known drugs with 'chemosensitizers' or 'chemoreversal' agents (CRA). Concerning the latter, we have focused on the resistance mechanisms developed against chloroquine (CQ). We have synthesized a series of compounds related to previously identified CRAs, and found promising novel compounds. These compounds show encouraging results in a coumarin labeled chloroquine uptake assay, exhibiting a dose response in resensitising parasites to the antimalarial effects of chloroquine. Selected compounds show consistent potency across a panel of chloroquine and artemisinin sensitive and resistant parasites, and a wide therapeutic window. This data supports further study of CRAs in the treatment of malaria and, ultimately, their use in chloroquine-based combination therapies.

The invention provides compounds of Formula I: 1wherein m1 is 0 or 1; m2 is 1 or 2; R1 is —H, alkyl, halogenated alkyl, substituted alkyl, cycloalkyl, or phenyl; R2 is —H, alkyl, halogenated alkyl, substituted alkyl, cycloalkyl, or phenyl, provided that when m1 is 1 at least one of R1 and R2 is —H; or a pharmaceutically acceptable salt, pharmaceutical composition, a pure enantiomer or racemic mixture thereof. The invention also provides a method for treating a disease or condition in a mammal, wherein the α7 nicotinic acetylcholine receptor is implicated and for treating diseases where there is a sensory-gating deficit in a mammal comprising administering to a mammal a therapeutically effective amount of a compound of Formula I. These compounds may be in the form of pharmaceutical salts or compositions, and may be in pure enantiomeric form or may be racemic mixtures.
