Malaria is a ife-threatening disease caused by Plasmodium protozoa and the RBCs are functioned as the main target molecule for their survival inside human body where they transform heme into hemozoin, termed as malarial pigment, to reduce the toxicity towards the parasites. It is well established that inhibition of heme to hemozoin transformation can lead us to the recovery of the diseases and many of the available drugs are believed to be working via that pathway. However, the emerging drug resistance power of the malarial protozoa lead us to explore new approaches to inhibit the hemozoin inhibition. Using an invitro assay we have shown that some physiological ions (phosphate, chloride) significantly inhibit the hemozoin formation. We further developed an effective assay for heme to hemozoin transformation at higher pH (~4.5) mimicking the physiological condition and investigated the role of lipid membrane. We established that lipid component of vesicle greatly modulates the hemozoin formation.
