  • Patent number: 9173888
    Abstract: This invention provides new therapeutic potential of nandrolone or a derivative thereof, against protozoal diseases. More specifically, nandrolone or a derivative thereof exhibits anti-protozoal activity against Leishmania major. Anti-protozoal potential of nandrolone derivatives, such as compounds 1-8, can contribute in the development of effective therapies against protozoal diseases, such as leishmaniasis, trypanosomiasis, malaria, toxoplasmosis, babeosis, amoebic dysentery and lambliasis. Another aspect of the invention is a method of testing derivatives of nandrolone for anti-protozoal activity comprising growing Leishmania in the presence of the test derivative and determining the IC50 value.
