A method for producing an alkylamine derivative having a urea bond represented by formula (I), or a salt thereof, comprises the following steps (a) and (b), step (a):
and
step (b): deprotecting as necessary the reaction product obtained in step (a). The production method suitable for industrialization of the alkylamine derivative having a urea bond represented by formula (I), which is a compound highly useful as an agent having CaSR agonist effects is provided.
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 IC50 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.

The present invention is directed to compounds of formula I-V and tautomers thereof or pharmaceutically acceptable salts, esters, and prodrugs thereof which are inhibitors of syk kinase. The present invention is also directed to intermediates used in making such compounds, the preparation of such a compound, pharmaceutical compositions containing such a compound, methods of inhibition syk kinase activity, methods of inhibition the platelet aggregation, and methods to prevent or treat a number of conditions mediated at least in part by syk kinase activity, such as undesired thrombosis and Non Hodgkin's Lymphoma.
