Background and Purpose
Efficacy of current antimalarial treatments is declining as a result of increasing antimalarial drug resistance, so new and potent antimalarial drugs are urgently needed. Azithromycin, an azalide antibiotic, was found useful in malaria therapy, but its efficacy in humans is low.
Experimental Approach
Four compounds belonging to structurally different azalide classes were...
Designed, synthetic heterocyclic diamidines have excellent activity against eukaryotic parasites that cause diseases such as sleeping sickness and leishmania and adversely affect millions of people each year. The most active compounds bind specifically and strongly in the DNA minor groove at AT sequences. The compounds enter parasite cells rapidly and appear first in the kinetoplast that contains...
Purpose. The purpose of this work was to develop and validate a method that can be used to quantify drugs associated with intracellular compartments. Methods. The human leukemic cell line U-937 was used to evaluate the distribution of model compounds with known and different subcellular distribution profiles. Lysotracker Red is a lysosomal vital stain and doxorubicin is an anticancer agent with...
