3WWR - PubMed Abstract: 
We synthesized and evaluated novel vitamin D3 derivatives with cyanoalkyl side chain at C-2 position on the basis of our previous research for 2α side chain which bears nitrogen atom-containing functional group. Through a study of X-ray co-crystal structures of human VDR and compound 3, we demonstrated that the 2α alkyl side chain in compound 3 shows a novel interaction in the complex of hVDR-LBD and ligand. This article is part of a Special Issue entitled '17th Vitamin D Workshop'.
