Background
ZK168281 is a 25-carboxylic ester 1α,25(OH)2D3 analog and a pure VDR antagonist with a Kd value of 0.1 nM. ZK168281 is an effective inhibitor of the coactivator (CoA) interaction of its receptor[1].
ZK168281 resembles more the mouse constitutive androstane receptor (CAR) inverse agonist Androstanol in its ability to recruit corepressor (CoR) proteins. A salt bridge between the CoR and a conserved lysine in helix 4 of the nuclear receptor (NR) is central to this interaction, but also helix 12 was stabilized by direct contacts with residues of the CoR. Fixation of helix 12 in the antagonistic/inverse agonistic conformation prevents an energetically unfavorable free floatation of the C terminus[1].
