[CHARACTERISTICS OF PARASITIC PROTOZOA METABOLISM AND POSSIBILITIES OF ANTIPROTOZOA DRUG DEVELOPMENT (REVIEW)].

One of the most poorly studied areas of protozoology is metabolic processes of parasitic protozoa. Study of the biochemistry of parasites required for the development of effective chemotherapy of protozoal diseases. Some amitochondrial parasites of humans, such as Giardia intestinalis, Entamoeba histolytica, Trichomonas sp., living in an environment with low oxygen content, have specialized cellular organelles-hydrogenosomes (like mitochondria provide cells with simple energy). The study of the functioning of these organelles allows us to consider them as targets for the development of аntiprotozoal drugs. The target for chemotherapy in the treatment of trypanosomiasis can be processes related to the characteristics of the glycolytic pathway or a decrease in the level of energy substrate, such as glucose. This leads to a rapid decrease in ATP levels in the cell of the parasite, an overall loss of mobility and disappearance of trypanosomes from the bloodstream of the infected host. Also, glucose transporters located in the membrane of the parasite can be targets for drugs.
