Based on 2 publication(s) in Google Scholar
TEI-9647, a Vitamin D3 Lactone analogue, is a potent and specific vitamin D receptor (VDR) antagonist. TEI-9647 inhibits VDR/VDRE-mediated genomic actions of 1α,25(OH)2D3. TEI-9647 inhibits bone resorption and HL-60 cell differentiation induced by of 1α,25(OH)2D3. TEI-9647 has the potential for suppressing the excessive bone resorption and osteoclast formation in Paget's disease.

TEI-9647 (100 nM; 24 hours) treatment clearly suppresses p21WAF1,CIP1 gene expression induced by 1α,25(OH)2D3[1].
TEI-9647 (10-1000 nM; 96 hours) dose-dependently blocks the reciprocal changes of CD11b and CD71 expression associated with HL-60 cell differentiation induced by 1α,25(OH)2D3. TEI-9647 completely blocks the increase in CD11b and the decrease in CD71 expression at 100 nM[1].
TEI-9647 blocks both 1α,25(OH)2D3-mediated HL-60 cell differentiation and also activation of the luciferase reporter in COS-7 cells that has been transfected with the cDNA containing the DRE of the rat 25(OH)D3-24-hydroxylase gene and cDNA of the human vitamin D nuclear receptor[1].
TEI-9647 can not induce cell differentiation even after treatment at 1 μM in HL-60 cell. TEI-9647 alone can not induce activation of NBT-reducing activity or α-NB esterase activity. In contrast, TEI-9647 markedly suppresses the up-regulation induced by 1α,25(OH)2D3 (0.1 nM) in HL-60 cells[1].
TEI-9647 (0.001-1 μM; for 10 days) dose-dependently inhibits bone resorption induced by of 1α,25(OH)2D3 (1 nM). TEI-9647 alone never induces bone resorption even at 1 μM[2].
TEI-9647 (10 nM; 12 h) markedly inhibits TAFII-17 and 25-OH-D3-24-hydroxylase gene expression induced by 1α,25(OH)2D3 (0.1 nM) in bone marrow cells[2].

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
