Bassianolide

Bassianolide is a cyclodepsipeptide insecticide synthesized by the fungal species B. bassiana and V. lecanii.{34745, 34746} In vivo, the oral administration of bassianolide induces atony in the silkworm B. mori at a concentration of 4 ppm and is lethal at doses exceeding 8 ppm. Atony is similarly induced in silkworm larvae at oral doses as low as 2 µg/larva. In isolated guinea pig smooth muscle tissue, bassianolide (0.01-1 µM) specifically inhibits the muscarinic, but not nicotinic, receptor-induced contractions in response to acetylcholine.{34747, 34748}Formal Name: Cyclo[(2R)-2-hydroxy-3-methylbutanoyl-N-methyl-L-leucyl-(2R)-2-hydroxy-3-methylbutanoyl-N-methyl-L-leucyl-(2R)-2-hydroxy-3-methylbutanoyl-N-methyl-L-leucyl-(2R)-2-hydroxy-3-methylbutanoyl-N-methyl-L-leucyl].
