Abstract:
:A natural avermectin complex, aversectin C, was shown to be capable of exerting selective cytostatic and neurotoxic effects on mammalian cells. Specifically, it killed proliferating neuroblastoma B103 cells but was non-toxic for differentiated cells of this culture. The antiproliferation action of aversectin C was not inhibited by bicuculline or picrotoxin, antagonists of the GABAalpha receptors, and was partly due to the action of avermectin A1, a component of aversectin C. Aversectin C irreversibly suppressed activity of 60% neurons in medial septal slices of the rat brain. More than 55% of them were the GABAalpha- and B1-sensitive neurons whereas the rest, about 45% neurons, were the GABAalpha-insensitive and the neurotoxic effect of aversectin C was caused mainly by the B2 component.
