ABSTRACT:
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, R0represents a water-soluble functional group, m represents any one of integers of from 0 to 6, n represents any one of integers of from 0 to 10.].
