is a substituent represented by the following formula (II-1), (III-1), or (IV-1)
(wherein R
3
, R
4
, R
5
, n, and X
1
have the same definitions as those described in the specification), and R
2
is a pyridyl, indazolyl, phenyl, pyrazolopyridyl, benzisoxazolyl, pyrimidinyl, or quinolyl group, each of which optionally has at least one substituent.
The present disclosure relates generally to compounds which bind to the NR1H4 receptor (FXR) and act as agonists of FXR. The disclosure further relates to the use of the compounds for the preparation of a medicament for the treatment of diseases and/or conditions through binding of said nuclear receptor by said compounds and to a process for the synthesis of said compounds.

The retinoicacidreceptor-relatedorphan receptor-gamma-t (RORγt) is a promising therapeutic target for treatment of Th17 cell-mediated autoimmune diseases. Based on a scaffold hopping/conformational restriction strategy, a series of N-indanyl benzamides as novelRORγtinverseagonists was discovered.
