6:2 Cl-PFAES
Based on 4 publication(s) in Google Scholar
6:2 Cl-PFAES is an orally effective alternative to Perfluorooctane sulfonate. 6:2 Cl-PFAES significantly inhibits the growth of zebrafish and induces reproductive toxicity. 6:2 Cl-PFAES reduces the relative weights of epididymis and testis in male BALB/c mice. 6:2 Cl-PFAES can be used in the chrome plating industry.

Biological Activity
6:2 Cl-PFAES (0.04-1.0 mg/kg/d; p.o.; daily; 56 days) reduces relative testis weight by 8% and absolute/relative epididymis weights by 14% and 16%, respectively, at the highest dose of 1.0 mg/kg/d, but does not alter reproductive hormones, histopathology, sperm quality, fertility, or testicular gene/protein expression in adult male BALB/c mice[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model:Tüebingen (5-month-old sexually mature adults, F0 generation; F1 and F2 generations derived from F0 fish)[1]
-
Dosage:5 μg/L; 50 μg/L; 500 μg/L
-
Administration:waterborne; continuous; 180 days (F0 generation); no direct exposure (F1 and F2 generations, maternal transfer)
-
Result:Significantly reduced body weight, body length, condition factor, and gonadosomatic index (GSI) in both sexes of F0 zebrafish at 5 and 50 μg/L.
Caused 85% mortality in male F0 zebrafish at 500 μg/L, with surviving fish unable to reproduce.
Reduced egg production per female F0 zebrafish at 5 and 50 μg/L.
Significantly increased serum testosterone, estradiol, and vitellogenin levels in male F0 zebrafish at 5 μg/L, and increased serum testosterone levels in female F0 zebrafish at 5 and 50 μg/L, altering T/E2 ratios.
Induced gonadal histological changes in F0 zebrafish at 5 and 50 μg/L: testes developed lacunae and reduced mature spermatocytes; ovaries had reduced mature oocytes.
Altered transcriptional levels of multiple hypothalamic-pituitary-gonadal (HPG) axis genes in F0 zebrafish at 5 and 50 μg/L, with down-regulation of brain genes (e.g., gnrh3, fshb, lhb) in most cases, and altered gonadal steroidogenic gene expression (e.g., increased cyp19a in testes, increased hmgra, star, cyp17 in ovaries).
Induced 1576 differentially expressed genes in testes of F0 zebrafish at 50 μg/L, enriched in pathways related to spermatogenesis (e.g., cytokine-cytokine receptor interaction, lysosome, focal adhesion).
Significantly reduced body weight, body length, and female GSI in F1 offspring from 5 μg/L exposed F0 parents; reduced serum testosterone levels in male F1 offspring.
Increased embryo malformation rate to 9.0% and 15.0% at 120 hpf, and increased mortality rates at 120 hpf in F1 offspring from 5 and 50 μg/L exposed F0 parents; F1 offspring from 50 μg/L exposed F0 parents died before 15 dpf.
Detected target reagent in adult blood (0.31 ng/mL males, 0.37 ng/mL females) and gonads (0.10 ng/mg males, 0.12 ng/mg females), and reduced mature oocytes in ovaries of F1 offspring from 5 μg/L exposed F0 parents.
Increased embryo malformation rate to 5.0% at 120 hpf and reduced survival rate in F2 offspring from 5 μg/L exposed F0 parents.

Reached testis 6:2 Cl-PFAES levels of 5.6 μg/g (0.04 mg/kg/d), 14.4 μg/g (0.2 mg/kg/d), and 49.93 μg/g (1.0 mg/kg/d), representing 5.9×103-, 1.5×104-, and 5.3×104-fold increases over control (0.95 ng/g).
Reached epididymis 6:2 Cl-PFAES levels of 1.69 μg/g (0.04 mg/kg/d), 2.68 μg/g (0.2 mg/kg/d), and 9.64 μg/g (1.0 mg/kg/d), representing 26.1-, 41.4-, and 149-fold increases over control (0.065 μg/g).
Showed no significant changes across all doses in serum or testicular testosterone, estradiol, follicle-stimulating hormone, or luteinizing hormone levels; testis/epididymis histopathology; sperm count; fertility metrics (mating index, litter size, pup birth/weaning weight, pup sex ratio); testicular gene expression profiles; or testicular levels of steroidogenic proteins (STAR, CYP11A1, CYP17A1, 3β-HSD) or cell junction proteins (occludin, β-catenin, connexin 43).
