The present invention provides compounds that have antimalarial activity. More in particular, the present invention provides novel compounds that are analogues of pantothenamides. The pantothenamide analogues of this invention have particularly low IC.sub.50 values against the asexual blood stages and gametocytes of malaria parasites. Furthermore, the pantothenamide analogues of this invention are characterized by low hepatic metabolism. Therefore, pantothenamide analogues of the invention are particularly suitable for use in therapeutic and/or prophylactic treatment of protozoan infections in a human or animal subject in need thereof. The invention further provides pharmaceutical formulations comprising the pantothenamide analogues as well as the therapeutic and/or prophylactic uses of the pantothenamide analogues and pharmaceutical formulations comprising them.

An immunogen useful for treating malaria generally includes an immunogenic carrier and an antigenic malaria circumsporozoite protein (CSP) peptide that includes the peptide NANPNVDPNANPNVD (SEQ ID NO:2) linked to the immunogenic carrier. The immunogen may be administered to a subject having or at risk of having malaria. Alternatively, the immunogen may be administered to an individual having or at risk of having Plasmodium falciparum blood stage parasitemia. In some cases, the immunogen can be administered in combination with another therapeutic agent for treating malaria of Plasmodium falciparum blood stage parasitemia.

Disclosed herein are methods of treating conditions, which may be associated with elevated levels of eosinophils and/or basophils, with a therapeutically effective amount of dexpramipexole or pharmaceutical acceptable salt thereof.

Monomers and copolymers are provided that both target antigen presenting cells (APCs) and activate toll-like receptor (TLR) on the APCs. In some embodiments, compositions and methods involve a polymer that targets the mannose receptor on APCs, in addition to activating a TLR. These can then be conjugated to protein antigens to efficiently target antigens to DCs and simultaneously induce the up-regulation of co-stimulatory molecules that are essential for effective T cell activation. This copolymer is a more efficient activator of DCs, as measured by the surface expression of co-stimulatory molecules and the release of proinflammatory cytokines, than the monomeric form the TLR agonist used in the polymer formulation. Aspects of the disclosure relate to novel compounds, methods, and compositions for treating diseases using the compounds, copolymers, and compositions described herein.
