RESUMO

A number of 1'-substituted 9-anilinoacridines were evaluated for their activities against promastigote and amastigote forms of Leishmania major and for their toxicities to human Jurkat leukemia cells. Several compounds possessing 1'-NH-alkyl substituents produced more than 80% growth inhibition of macrophage-infected L. major amastigotes at or below a concentration of 1 microM. 1'-Hexylamino-9-anilinoacridine (compound 14) was the least toxic compound to human Jurkat cells, while it retained strong antileishmanial activity. There was a general trend for the more lipophilic compounds to show the greatest antileishmanial activity, whereas 3,6-di-NH2 substitution of the acridine nucleus reduced or eliminated activity. Some structure-activity relationships of the various compounds are discussed.
