Membrane effects of dihydropyrimidine analogues with larvicidal activity
Colloids and Surfaces B: Biointerfaces, 2017 Two recently synthesized dihydropyrimidines (DHPMs) analogues have demonstrated larvicide and repellent activity against Anopheles arabiensis. DHPMs high lipophilicity suggests that these compounds may interact directly with the membrane and modify their biophysical properties.

Schistosoma mansoni larvicidal activity of murine bronchoalveolar lavage cells [PDF]
Infection and Immunity, 1990 We have investigated the ability of cells obtained from both normal and immune mice by bronchoalveolar lavage (BACs) to kill Schistosoma mansoni larvae in vitro. In cultures with mechanically derived schistosomules, high levels of larvicidal activity were displayed by BACs from both normal and irradiated cercaria-immunized C57BL/6 mice.
