(197) Specifically, the court found that, although five of eighteen disclosed androstanes
were claimed, the specification did not identify which androstanes
were useful or what biological properties they possessed:

Homology modelling of the nuclear receptors: Human oestrogen receptorbeta (hERbeta), the human pregnane-X-receptor (PXR), the Ah receptor (AhR) and the constitutive androstane
receptor (CAR) ligand binding domains from the human oestrogen receptor alpha (hERalpha) crystal structure, and the human peroxisome proliferator activated receptor alpha (PPARalpha) ligand binding domain from the human PPARgamma crystal structure.

Induction of CYP3A4, CYP2C19, and CYP2C9 by the prenyloxycinnamic acids is most likely mediated via the pregnane x receptor (PXR), which regulates the expression of many CYPs and which is the major nuclear receptor in LS180 cells lacking the constitutive androstane
receptor (CAR) (Gupta et al.
There are two groups of families of neurosteroids: the inhibitory neurotransmitter receptor families of pregnane neurosteroids that include allopregnanolone and aIlotetrahydrodeoxycorticosterone, and the excitatory neurotransmitter receptor families of androstane
neurosteroids, such as androstanediol and etiocholanone.
Some PBDEs have been shown to cause pregnane X receptor (PXR)--and constitutive androstane
receptor (CAR)-mediated induction of liver enzymes responsible for thyroid hormone clearance, which might compromise brain development by causing thyroid hormone insufficiency (EFSA 2011; Costa and Giordano 2011).
