Transcription factor that mediates the action of vitamin D3 by controlling the expression of hormone sensitive genes. Regulates transcription of hormone sensitive genes via its association with the WINAC complex, a chromatin-remodeling complex. Recruited to promoters via its interaction with the WINAC complex subunit BAZ1B/WSTF, which mediates the interaction with acetylated histones, an essential step for VDR-promoter association. Plays a central role in calcium homeostasis. Publication Abstract from PubMed Nonsecosteroidal vitamin D receptor (VDR) ligands are promising drug candidates for multiple diseases, including osteoporosis, psoriasis, and certain cancers. We report here the design, synthesis, biological evaluation and crystallographic analysis of a series of 1,7-diphenyl-m-carborane derivatives as novel nonsecosteroidal VDR ligands. We found that the 1,7-diphenyl-m-carborane framework is a promising hydrophobic core of VDR ligands, and developed a series of potent compounds such as 12b and 13a. Interestingly, compounds with different chain length exhibited similar potencies. X-Ray co-crystal structure analysis revealed that the developed compounds exhibited various different interaction patterns depending on the structure of the carboxyalkyl chain, indicating that the ligand-binding pocket of the VDR possesses sufficient conformational plasticity to accommodate a wide variety of ligands without compromising activity. The developed carborane derivatives are promising leads for further structural development, and the findings on the diversity of binding modes will be helpful in the design of other VDR ligands.
