Aminoalkyl glucosamine phosphate compounds that are adjuvants and immunoeffectors are described and claimed. The compounds have a 2-deoxy-2-amino glucose in glycosidic linkage with an aminoalkyl (aglycon) group. Compounds are phosphorylated at the 4 or 6 carbon on the glucosamine ring and comprise three 3-alkanoyloxyalkanoyl residues. The compounds augment antibody production in immunized animals as well as stimulate cytokine production and activate macrophages. Methods for using the compounds as adjuvants and immunoeffectors are also disclosed.

Human African trypanosomiasis (HAT), caused by the protozoan parasite Trypanosoma brucei spp., is a major health problem in sub-Saharan Africa. New drugs are urgently required for the disease. Selective uptake of toxic compounds into trypanosomes has been achieved by exploiting plasma membrane transporters. For example, the P2 aminopurine transporter, along with other transporters, selectively concentrates melamine and benzamidine moieties into trypanosomes. We have previously reported the use of the melamine motif to selectively target nitrofuran to the trypanosome. In this paper we report the further investigation of the structure activity relationships and the effect of the introduction of different functionalized substituents onto the melamine unit. Most of the compounds tested in vitro for their trypanocidal activity showed activities in the submicromolar range against T. b. rhodesiense.

inhibitors of the enzyme can be designed and synthesised with the aim of being developed into novel anti-parasitic drugs. Analogue based design was used to target the PlasmodiumfalciparumdUTPase (PfdUTPase). The structures of previously discovered selective inhibitors of the PfdUTPase were modified by insertion of an amide bond. A series of tritylated uracil acetamide derivatives were synthesised
