anti-insect

Isoasatone A, a natural product isolated from the plant [Heterotropa takaoi M.], exhibits anti-insect activity.

Itch-Targeting Compound 1 is an anti-itch agent effective in preventing or treating reactions from insect bites, environmental allergens, skin infections, external vermination, or itching in renal dialysis patients.

Thiacloprid is a neonicotinoid insecticide that acts as a selective agonist at insect nicotinic acetylcholine receptors (nAChRs) with IC50values of 2.7 and 860 nM forDrosophilanAChRs and M10 mouse fibroblast cells expressing α4β2 subunit-containing nAChRs, respectively.1It is active against aphids, whiteflies, various species of beetle, andLepidopteraspecies when used at concentrations ranging from 48 to 180 g AI/hectare.2It has anti-estrogenic activity in a yeast estrogen screen and is toxic to adult female houseflies and mice (LD50s = 0.03 and 28 mg/kg, respectively).1,3Formulations containing thiacloprid have been used in the control of insects in agriculture. 1.Tomizawa, M., and Casida, J.E.Selective toxicity of neonicotinoids attributable to specificity of insect and mammalian nicotinic receptorsAnnu.

Nerolidol acetate is a natural sesquiterpene with anti-cancer, anti-inflammatory, antibacterial and anti-insect activities. Nerolidol acetate can inhibit parasite activity and inhibit schistosomiasis, nematodes, malaria, etc. Nerolidol acetate protects cells from oxidative damage to lipids, proteins and DNA, and has a protective effect on mouse hippocampal nerve cells.

Janthitrem A is a mycotoxin that has been found inP. janthinellum.1It induces tremors in mice and decreases the time to fall from the rotarod when administered at a dose of 4 mg/kg.2Janthitrem A (20 μg/g) also reducesW. cervinatalarvae weight gain and food consumption. 1.Gallagher, R.T., Latch, G.C., and Keogh, R.G.The janthitrems: Fluorescent tremorgenic toxins produced by Penicillium janthinellum isolates from ryegrass pasturesAppl.

7(Z)-Tricosene is an insect pheromone and endogenous metabolite for mating and interspecific recognition.

ω-Hydroxy-DEET, a significant metabolite of the insect repellent N-N-diethyl-meta-toluamide (DEET), exhibits anti-proliferative properties. DEET, renowned for being a spatial repellent and irritant, is frequently employed to deter mosquito contact.

Juvenile hormone B 3 (Juvenile hormone III bisepoxide) (mixture of diastereomers) is a sesquiterpenoid hormone. It can be isolated from the corpora allata (CA) of higher dipteran insects such as fruit flies and Drosophila melanogaster. This hormone exhibits anti-metamorphic activity and induces the expression of Kr-h1 by directly interacting with juvenile hormone (JH) receptors (Met and Gce). Juvenile hormone B 3 (mixture of diastereomers) is applicable in insect lethality studies.

Arjunetin, a natural product isolated from Terminalia arjuna, exhibits binding affinity for SARS-CoV-2 and demonstrates potential antiviral activity.

Lactupicrin is a natural product discovered in chicory, exhibiting analgesic, sedative, antimalarial, and anti-atherosclerotic effects. It inhibits NF-κB activation and LDLR1 production, and demonstrates inhibitory activity against yeast alpha-glucosidase (IC50 = 14.71 µM).

Nimbin is an anti-pyretic, can be used to treat arthritis, hypoglycaemia, peptic ulcers, anti-secretory activity, and it can also be used as an antibiotic. Nimbin requires to elicit a 50% inhibition of this steroid hydroxylase activity in the three insect

Piperenone is an insect antifeeding substance. It has anti-platelet-activating factor(PAF) activities, is a PAF-acether antagonist.

Rubrosterone is a steroid and C19 steroid found in certain plants and insects, exhibiting anti-diabetic activity.

Vestitol is a phytoalexin with insect feeding-deterrent activity, it has antioxidant, anti-inflammatory and antimicrobial activities, it can inhibit neutrophil migration at a dose of 10 mg/kg, and shows MICs ranging from 25-50 to 50-100 ug/mL and MBCs ranging from 25-50 to 50-100 ug/mL.Vestitol exerts a limited inhibitory effect on S. hermonthica germination, it can significantly inhibit seedling growth, it also contributes, at least in part, to the host's defence mechanism and acts as a chemical barrier against the intrusion of the parasite.
