Methoprene (Synonyms: 烯蟲酯; ZR-515)
Methoprene 是一種昆蟲幼年生長ji素的模擬物，是一種生長調(diào)節(jié)殺蟲劑，通過作為幼年ji素 (juvenile hormone) 激動劑來顯示其對靶生物的毒性。
生物活性
Methoprene, an insect juvenile growth hormone mimic, is a growth-regulating insecticide that manifests its toxicity to target organisms by acting as a juvenile hormone agonist[1][2].
體外研究(In Vitro)
Methoprene reduces the growth rate of daphnids with evidence of only a single concentration-response line, having a threshold of 12.6 nM. Molt frequency is reduced by methoprene in a concentration-dependent manner, with a response curve corresponding to a 2-segmented line and thresholds at 4.2 and 0.21 nM. An endpoint related to reproductive maturation, the time of first brood deposition, is also affected by methoprene, with a clear concentration-dependent response and a NOEC of 32 nM. Methoprene reduces fecundity according to a 2-segmented line, with thresholds of 24 and < or =0.18 nM. Methoprene elicits significant toxicity to endocrine-related processes in the 5-50 nM concentration range[1].
