Quality Control of 4-(2-Phenylpropan-2-yl)phenolIn 2022, Nakazawa, Tomomi;Yamaguchi, Yuko;Fukunaga, Yachiyo;Tamura, Kazutoshi published 《A possible critical dosing period of p-cumylphenol for development of cystic kidneys in rat neonates》. 《Journal of Toxicologic Pathology》published the findings. The article contains the following contents:
In accordance with a previous report on cystic kidneys induced in rat neonates when dosed with p-cumylphenol (PCP) for 18 days from postnatal day (PND) 4, 3 rat neonates were dosed with PCP once a day for 14 days, either from PND 14, 21, 28, 35, or 42 as W2, W3, W4, W5, and W6 groups, resp., to investigate whether dosing periods in different PNDs influenced the development of cystic renal tubules. The lesion was striking in the W2 group and at a lesser magnitude in the W3 group, whereas either kidney was unaffected when dosing was initiated beyond PND 28. These findings, together with the results from the previous study, suggested that PND 14-28 is a critical dosing period for PCP to develop cystic kidneys in rat neonates. The lining epithelium of the cystic tubules was immunohistochem. pos. for AQP2. This finding and the anatomical location indicated that the cystic tubules were of collecting duct origin. Either obstruction, fluid accumulation, or reparative hyperplasia of the lining epithelium was unlikely to be involved in the formation of cystic tubules lined with a monolayer of cuboidal or columnar epithelium with a high nuclear d. Thus, the follow-up investigation on PCP suggested a critical dosing period of PND 14-28 in rat neonates for the development of cystic dilation of renal collecting ducts. This study further supports that additive hyperplasia of the lining epithelium is a fundamental basis of this unique lesion. To complete the study, the researchers used 4-(2-Phenylpropan-2-yl)phenol (cas: 599-64-4) .
4-(2-Phenylpropan-2-yl)phenol(cas:599-64-4) is a natural product found in Panax ginseng.Quality Control of 4-(2-Phenylpropan-2-yl)phenol 4-(2-Phenylpropan-2-yl)phenol is a useful reagent for preparing and characterizing aromatic polyphosphonates as high refractive index polymers.
