Chlorfluazuron
Based on 1 Customer Validation
Chlorfluazuron (IKI-7899) is a benzoylurea chitin synthesis inhibitor and a PPARγ agonist ligand that blocks the polymerization of UDP-N-acetylglucosamine by inhibiting chitin synthase, disrupting cuticle formation, molting, and embryonic development, thereby exerting ovicidal, larvicidal, and fecundity-reducing effects in insects. Chlorfluazuron is used in hepatotoxicity research.

Description
In Vitro
Chlorfluazuron (IKI-7899) (0.166 ppm) treatment of Spodoptera littoralis 4th instar larvae results in histological abnormalities in female ovaries, including shrunken oocytes with peripheral spaces, semi-absorbed oocytes, and thin and slightly vacuolated follicular epithelium[2].
Chlorfluazuron (0.166 ppm; 48 h) treatment of Spodoptera littoralis 4th instar larvae decreases total protein (23.6 mg/g), carbohydrate (46.2 mg/g), and lipid (88.3 mg/g) contents in the ovarioles[2].
Chlorfluazuron (72 h) is highly toxic to 4th-instar Bradysia odoriphaga larvae, with an LC50 of 0.1593 mg/L at 72 h[3].
Chlorfluazuron (0.0255-0.1593 mg/L) suppresses Bradysia odoriphaga population growth under sublethal LC50 treatment by reducing the intrinsic rate of increase and finite rate of increase, net reproductive rate, survival rate, and fecundity, whereas sublethal LC10 treatment stimulates population growth by enhancing fecundity and shortening developmental time[3].
Chlorfluazuron (0.0255-0.1593 mg/L; administered daily from day 11 to day 16 after oviposition) inhibits the feeding of last-instar larvae of Bradysia odoriphaga in the short term, and this inhibitory effect is temporary and reversible[3].
Chlorfluazuron (0.0255-0.1593 mg/L; 24-72 h) initially decreases total protein levels at LC10 and LC50 concentrations but subsequently increases them, and significantly enhances GST and MFO activities in 4th-instar larvae of Bradysia odoriphaga after 48 and 72 h of treatment[3].
Chlorfluazuron exhibits high activity against third-instar larvae of Choristoneura fumiferana, first-instar larvae of Platynota stultana, and first- to second-instar larvae of Spodoptera exigua, with LC50 values of 0.27, 1.36, and 0.23 ppm, respectively[4].
Chlorfluazuron (25-0.3906 ppm; 6 days) is highly toxic to newly hatched Pectinophora gossypiella larvae, with an LC50 of 17.47 ppm and an LC90 of 253.360 ppm[5].
Chlorfluazuron (17.47 ppm; 10 days) significantly decreases total soluble protein and increases total lipid in 10-day-old Pectinophora gossypiella larvae, and increases the activities of invertase, trehalase, and amylase in 10-day-old Pectinophora gossypiella larvae[5].
Chlorfluazuron (17.47 ppm; 10 days) decreases AST activity and increases ALT activity in 10-day-old Pectinophora gossypiella larvae[5].
Chlorfluazuron (17.47 ppm; 10 days) causes histopathological alterations in the cuticle of 10-day-old Pectinophora gossypiella larvae, including thickening of the epicuticle and thinning of the endocuticle[5].

Chlorfluazuron (500-2500 ppm; 7 days) is toxic to Eobania vermiculata through contact, with an LC50 of 1528.0 ppm after 7 days[7].
Chlorfluazuron (500-2500 ppm; 7 days) is toxic to Eobania vermiculata via bait, with an LC50 of 1992.5 ppm after 7 days, but its toxicity is lower than that of the contact technique[7].
Chlorfluazuron (LC50 value; 7 days) causes severe malformations in the reproductive system of Eobania vermiculata, including swelling of the penis, vagina, and albumen gland, as well as loss of eggs from the ovotestis[7].
Chlorfluazuron (10 mg/L; 2 h) degrades under visible light irradiation in the presence of a C3N4 nanofilm, with a half-life of 1.73 h[8].
Chlorfluazuron (0.2-100 mg/L; 72 h) concentration-dependently affects the growth of Scenedesmus obliquus, with 5.0 mg/L resulting in cell viability exceeding 70%[8].
Chlorfluazuron (0.5-5.0 mg/L; 72 h) exposure significantly alters chlorophyll content in Scenedesmus obliquus in a concentration-dependent manner[8].
Chlorfluazuron (1 nM-10 μM; 24 h) acts as a PPARγ agonist in HepG2 cells, with an REC20 of 4.81 × 10-7 M and an RLA of 27.2%, exhibiting the second-highest relative agonistic potency among the five active CSIs[6].
Chlorfluazuron (below 10 μM; 24 h) does not induce significant cytotoxicity in HepG2 cells[6].
Chlorfluazuron (0.5-5.0 mg/L; 72 h) exposure induces severe oxidative stress in Scenedesmus obliquus, leading to increased Superoxide dismutase, Porcine erythrocytes (SOD) (HY-129064) activity and decreased CAT content within 72 h[8].
Chlorfluazuron (28.75-460 mg/L; mycelial growth for 14 days, conidial germination for 48 h) maintains high compatibility with Metarhizium rileyi, and does not inhibit mycelial growth, sporulation, or conidial germination within the tested dose range[9].

Chlorfluazuron (0.166 ppm; dietary exposure via treated castor leaves) is the most toxic IGR against S. littoralis 4th instar larvae, with an LC50 of 0.166 ppm, and it significantly reduces adult emergence, fecundity, fertility, and ovarian protein, carbohydrate, and lipid contents, while causing ovarian histological abnormalities[2].
Chlorfluazuron (25-0.3906 ppm; diet feeding; 1 hr) is highly toxic to neonate P. gossypiella larvae (LC50 = 17.47 ppm) and induces pronounced biochemical disturbances (decreased protein, increased lipid, elevated carbohydrate hydrolases and ALT, decreased AST), accompanied by severe cuticular histopathological and ultrastructural damage[5].
Chlorfluazuron (500-2500 ppm; topical film contact exposure; single exposure; 7 days) is effective against Eobania vermiculata, with LC50 values of 1528.0 ppm (contact) and 1992.5 ppm (bait) after 7 days of treatment[7].
