Sulfamates and sulfamides are most often synthesized from alcohols and amines with sulfamoylchloride, which is an unstable reagent. We have identified hexafluoroisopropyl sulfamate (HFIPS) as a bench-stable solid that reacts readily with a wide variety of alcohols, amines, phenols, and anilines under mild reaction conditions. The sole byproduct of the reaction is hexafluoroisopropanol (HFIP) and reaction

coordinate to the activesitezinc and form key hydrogen bonds with adjacent CA activesite residues. Both NPs were good to moderate CA inhibitors, with compound 2 a 20–50-fold stronger CA inhibitor (Ki values 65–234 nM) than compound 1. The protein X-ray crystalstructures of 1 and 2 in complex with CA II show that it is not the halogen-hydrophobic interactions that give compound 2 a greater binding energy

An object of the present invention is to provide a novel compound having antimalarial acitivity and an antimalarial agent containing the novel compound as an active component. An antimalarial agent containing 12-hidroxy-2-(1-methoxycarbonylethyl)-5-oxo-10,11,13-trioxatricyclo[7.2.0.01,6]tridecane represented by a following formula (II) as an active agent is prepared.
The present invention is to provide an antimalarial agent having excellent antimalarial activity with little side effects, in particular, having remarkable antimalarial activity against drug-resistant malaria parasites, and being capable of increasing solubility not only to organic solvent including olive oil, but also to water, and therefore, being usable not only as oral drugs but also as injectable solutions. The antimalarial agent of the present invention contains a compound represented by the following general formula (I) [wherein Z represents an unsubstituted or optionally substituted alicyclic hydrocarbon group, R
