Permethrin exhibits a wide spectrum of bioactivities with significant parasiticidal, insecticidal, and antifeedant properties. It demonstrates potent parasiticidal activity against Rhipicephalus sanguineus with an LD50 of 0.14 µg per tick and shows strong insecticidal effects against various insect species such as Periplaneta americana, Ascia monuste orseis, Sitophilus zeamais, and Acanthoscelides obtectus, with mortality rates ranging from 17.5% to 100%. The compound also inhibits feeding in Tineola bisselliella and Anthrenocerus australis larvae at a concentration of 0.01% w/w, leading to substantial wool weight loss. In assays, it exhibits mosquito larvicidal activity against Culex quinquefasciatus with LC50 values of 0.005 ppm and 0.16 ppm for susceptible and resistant strains, respectively.
Permethrin shows a high lipophilicity with a log P value of 7.38, indicating a strong affinity for lipid environments. It also has a high octanol-water partition coefficient (log KOW = 6.1), suggesting potential for bioaccumulation in aquatic environments. The compound is active in a variety of receptor and enzyme interactions, displaying both agonist and antagonist activities and interacting with receptors such as HRH2, BDKRB2, GHSR, and AGTR1.
It is also effective against first-instar larvae of Cheumatopsyche brevilineata and Daphnia magna, with higher toxicity toward the former. However, it exhibits no bioactivity related to liver injury or hepatic side effects based on DILIps assessments, with HepSE scores reported as 0.0. While strong contact toxicity is observed against adult Tetragonisca angustula, adult Solenopsis saevissima, and second-instar larvae of Tuta absoluta, the compound demonstrates high selectivity for particular pest control strategies.
In therapeutic contexts, Permethrin shows promise in various biochemical pathways, indicating potential as a treatment for conditions such as Ataxia-Telangiectasia. Its potency ranges from 1.4 nM to above 420,000 nM in diverse bioassays, including those targeting Lamin A splicing, TDP1, histone lysine methyltransferases, and others. It also impacts liver enzyme activity, increasing levels of composite activity markers like SGOT, SGPT, and LDH. Overall, Permethrin is a versatile agent with significant bioactivity across multiple domains..
