Two widely studied parasite protein families are considered attractive targets for developing a fully effective antimalarial vaccine: the erythrocyte binding antigen (EBA) family defining a sialic acid-dependent invasion pathway, and reticulocyte-binding homologue (RH) proteins associated with sialic acid-independent red blood

Plasmodium falciparum merozoite surface proteins (MSP-1 to -11) have been involved in merozoite interaction with the red blood cell (RBC) surface. Peptides covering complete MSP-4 and MSP-7 amino acid sequences were synthesized and tested in RBC binding assays. One MSP-4

Aminomethylation of 9b,10-dihydro-1H-indolo[1,7:4,5,6]pyrrolo[3,4:2,3][1,4]diazepino-[1,7-a]indole-1,3(2H)-diones or 1H-indolo[1,7:4,5,6]pyrrolo[3,4:2,3][1,4]diazepino[1,7-a]indole-1,3(2H)-diones resulted in dialkylaminomethyl derivatives. Alkylation of the nitrogen atom of maleimide moiety of polyannelated diazepines with 1,3-dibromopropane and subsequent reaction with thiourea or its N-alkyl derivatives gave isothiourea-carrying compounds. The compounds containing isothiourea moiety were

Detergent resistant membranes (DRMs) of Plasmodium falciparum merozoites contain a large number of glycosylphosphatidylinositol (GPI)-anchored proteins that have been implicated in interactions between merozoites and red blood cells (RBCs). In this study, two cysteine-rich proteins anchored by GPI to merozoite
