Antimalarials V: aminobenzothiazoles.

ABSTRACT

Four mono- and dialkylated 4-aminobenzothiazoles (VII-X) were prepared as analogs of potent causal prophylactic drugs in the 8-aminoquinoline series. Compounds VII and VIII were toxic at 80 mg/kg in the chick; IX was inactive at 640 mg/kg. In a sporozoite-induced mouse test system, X was inactive at 30 mg/kg and toxic at 480 mg/kg. None of the compounds was active as a suppressive drug.
