Bivalent Carbamates as Novel Control Agents of the Malaria Mosquito, Anopheles gambiae.

Widespread pyrethroid resistance has caused an urgent need to develop new insecticides for control of the malaria mosquito, Anopheles gambiae. Insecticide discovery efforts were directed towards the construction of bivalent inhibitors that occupy both the peripheral and catalytic sites of the mosquito acetylcholinesterase (AChE). It was hypothesized that this approach would yield a selective, high potency inhibitor that would also circumvent known catalytic site mutations (e.
