Beveridge, Elizabeth published the artcileActivity of phenanthridine compounds against Babesia rodhaini in mice, Recommanded Product: Dimidium bromide, the publication is Annals of Tropical Medicine & Parasitology (1956), 85-91, database is CAplus.
A series of phenanthridine compounds previously reported to have trypanocidal activity (C.A. 44, 8545e) was tested against B. rodhaini in mice. General requirements for babesicidal activity are the same as for trypanocidal activity. For high potency against B. rodhaini there must be: (1) a 10-quaternary group; (2) at least one free amino or easily hydrolyzed acylamino group in the 2, 3, 6, or 7 position of the phenanthrene nucleus; (3) an alkyl, phenyl, or p-aminophenyl group in position 9. Urethan derivatives have little activity; and acylation of amino groups does not greatly diminish babesicidal potency, in contrast to the effect on trypanocidal action.
Annals of Tropical Medicine & Parasitology published new progress about 518-67-2. 518-67-2 belongs to bromides-buliding-blocks, auxiliary class Other Aromatic Heterocyclic,Salt,Amine,Benzene, name is Dimidium bromide, and the molecular formula is C20H18BrN3, Recommanded Product: Dimidium bromide.
