Abstract

The invention belongs to the technical field of chemical medicines and relates to a biaryl urea carboxylic acid derivative or a salt of the compound of formula I, as well as a preparation method, a medicinal composition and application of the compound in preparing medicines for treating diseases related to RORgamma t. Study results show that the compound can effectively inhibit RORgamma t protein receptors, so that differentiation of Th17 cells can be regulated and controlled, generation of IL-17 can be inhibited, treatment medicines for inflammation related diseases mediated by RORgamma t can be further prepared, and inflammation related diseases such as disseminated sclerosis, rheumatoid arthritis, collagen-induced arthritis, psoriasis, inflammatory bowel diseases, encephalomyelitis, clone diseases, asthma and cancer can be treated. The formula I is as shown in the specification.

Description

technical field [0001] The invention belongs to the technical field of chemical medicine, relates to a biaryl urea carboxylic acid derivative with general formula I and a RORγt inhibitory activity and a preparation method thereof, and also relates to the use of the biaryl urea carboxylic acid compound in the preparation of therapeutic Use of a drug for a disease associated with RORyt. Background technique [0002] Retinoic acid receptor-related orphan receptors (retinoic acid receptor-related orphan receptors, RORs), also known as NF1R, is a member of the nuclear receptor superfamily of ligand-dependent transcription factors. The RORs subfamily mainly includes three members: RORα, RORβ and RORγ. There are two different subtypes of RORγ: RORγ1 and RORγt (also known as RORγ2), in which RORγ1 is distributed in skeletal muscle, thymus, testis, pancreas, prostate, heart and liver, etc., while RORγt is only expressed in certain immune cells . [0003] Littman et al. first repor...
