Dinotefuran
Based on 4 publication(s) in Google Scholar
Dinotefuran is an orally active and competitive inhibitor and insecticide targeting insect nicotinic acetylcholine receptors (nAChRs). Dinotefuran blocks neural signaling and induces neural dysfunction in insects. Dinotefuran binds to [3H]epibatidine in the neural cord membrane of American cockroach with an IC50 of 890 nM and to [3H]α-bungarotoxin with an IC50 of 36.1 μM. Dinotefuran exhibits knockdown activity (KD50=0.351 nmol/g) and lethal activity (LD50=0.173 nmol/g) against German cockroach. Dinotefuran is mainly used for agricultural pest control, such as field control of piercing-sucking and chewing insects (e.g., aphids, planthoppers), while its environmental toxicological effects (e.g., oxidative stress and reproductive neurotoxicity on earthworms) are also a research focus to assess ecological risks.

Biological Activity
Dinotefuran (1 μM; 120 min) competitively inhibits the binding of [3H]EPI to nicotinic acetylcholine receptors (nAChRs) in the neuronal cord membrane of American cockroaches[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
-
Cell Line:Periplaneta americana nerve cord membrane preparations
-
Concentration:IC50: 890 nM ((±)-Dinotefuran); 856 nM ((+)-Dinotefuran); 1890 nM ((-)-Dinotefuran)
-
Incubation Time:120 minutes
-
Result:Inhibited [3H]EPI binding with an IC50 of 890 nM, with (+)-enantiomer being ~2-fold more potent than (-)-enantiomer.
Dinotefuran (0.015%-0.06%; mixed in feed; daily intake) leads to prolonged movement time of F0 males, decreased fertility of females, increases birth weight and imbalanced sex ratio of F1 pups, delayes olfactory orientation of female offspring, decreases movement distance and speed of male offspring, and increased urination frequency[2].

-
Animal Model:Toxicity model in CD-1 mouse (4-week-old)[2]
-
Dosage:0% (control), 0.015%, 0.03%, and 0.06%
-
Administration:Oral, given in the basal diets (CE-2); 5 weeks of age of the F0 generation to 11 weeks of age of the F1 generation in mice.
-
Result:In F0 adult males, movement time during exploratory behavior significantly increased with dose-related trends), while rearing time and average rearing time decreased.
In F1 offspring, litter size and weight at birth increased in dose-related trends), but sex ratio (male/female) decreased significantly.
On postnatal day (PND) 21, offspring body weight increased in both sexes for males, for females).
Female offspring showed delayed olfactory orientation time on PND 14, while male offspring exhibited reduced total distance, average speed, and increased defecation frequency and urination.
