Description | Spinosad, a mixture of spinosyns A and D known as fermentation products of a soil actinomycete (Saccharopolyspora spinosa), is a biological neurotoxic insecticide with a broader action spectrum. Spinosad targets the nicotinic acetylcholine receptor (nAChRs) of the insect nervous system. Spinosad has an excellent environmental and mammalian toxicological profile. Larvicidal activity[1][2][3]. |

In Vitro | Spinosad acts as an allosteric agonist of acetylcholine (Ach) by binding to nicotinicacetylcholine receptors (nAChRs), prototypicalunits that function as neurotransmitter ligand-gated ion channels[4]. |
In Vivo | Spinosad is a natural mixture of the pediculicidal tetracyclic macrolides spinosyn A and spinosyn D. Spinosad 0.9% mainly interferes with nicotinic acetylcholine receptors in insects, thereby producing neuronal excitation that results in paralysis of lice from neuromuscular fatigue after extended periods of hyperexcitation. Spinosad 0.9% kills both permethrin-susceptible and permethrin-resistant populations of lice. It is also ovicidal, killing both eggs (nits) and lice[5]. Spinosad causes in vivo oxidative effects in the brain of Oreochromis niloticus. Spinosad causes elevations in the contents of tGSH, GSH, GSSG, Hsp70, and reductions in the ratio of GSH/GSSG and GPx activity and an induction in the GR (glutathione reducta) activity. Spinosad has oxidative effects in the brain tissue by altering the parameters in GSH-related antioxidant system and Hsp70[6]. |
