Fluoroquinolone resistance among Mycobacterium tuberculosis strains from Karachi, Pakistan: data from community-based field clinics.

abstract：:The endoperoxides are a new class of antimalarial agents, of which artemisinin (qinghaosu) is the prototype. We have previously shown that artemisinin is capable of alkylating proteins in model reactions. In the present study, we showed that when Plasmodium falciparum-infected erythrocytes are treated with a radiolabe...
