title: Plasmodium cynomolgi: gametocytocidal activity of the anti-malarial compound CDRI 80/53 (elubaquine) in rhesus monkeys.
abstract: The gametocytocidal action of a new enamine analogue of primaquine, elubaquine (compound CDRI 80/53, bulaquine), has been evaluated against Plasmodium cynomolgi B in rhesus monkeys. Colony bred Anopheles stephensi mosquitoes were fed on gametocyte carrying rhesus monkeys prior to and at varying intervals after oral administration of a single dose of elubaquine at doses ranging between 0.63 and 5.00 mg/kg. Complete loss of oocyst development and mosquito infectivity was observed within 24 h after administering a single 1.25 mg/kg dose, while higher dose of 3.75 mg/kg inhibited oocyst development within 5 h, indicating gametocytocidal action of the compound. Elubaquine did not show any action against developing oocysts in the vector.
