简介内容:TEI-9648, an analogue of Vitamin D3 Lactone, acts as a potent and specific antagonist to the vitamin D receptor (VDR). This compound effectively blocks the genomic actions mediated by VDR and the Vitamin D responsive element (VDRE) of 1α,25(OH)2D3. Furthermore, TEI-9648 prevents the differentiation of HL-60 cells induced by 1α,25(OH)2D3, indicating its utility in bone metabolism studies[1][2].
