Chemical compound and disease context of phenylbenzene

 

Biological context of phenylbenzene

  • In the substrate complexes, biphenyl rings of substrates are recognized by extensive hydrophobic interactions with the active site residues [22].
 

Anatomical context of phenylbenzene

  • The activity of Trp-P-2 N-hydroxylase in microsomes was increased by pretreating the animals with a polychlorinated biphenyl mixture [24].
  • Treatment of isolated adipose tissue in culture with TCDD and two biphenyl congeners produced a decrease in transport activity that matched the rank order of aryl hydrocarbon receptor affinity for the compounds [25].

  • Replacement of the P(1)' biphenyl substituent of CGS 26303 by a conformationally restricted 3-dibenzofuranyl group led to more potent and more selective ECE-1 inhibitors, such as the tetrazole 27 [32].
  • c-Src is the primary signaling mediator of polychlorinated biphenyl-induced interleukin-8 expression in a human microvascular endothelial cell line [33].
