IUPAC Name: (S)-5-((R)-2-((1R,3aS,7aR,E)-4-((Z)-2-((3S,5R)-3,5-dihydroxy-2-methylenecyclohexylidene)ethylidene)-7a-methyloctahydro-1H-inden-1-yl)propyl)-3-methylenedihydrofuran-2(3H)-one
InChIKey: SAODSJHDCZTVAT-CZADFQNYSA-N
SMILES: O=C1O[C@@H](C[C@H]([C@H]2CC[C@@]3([H])/C(CCC[C@]23C)=C/C=C4C([C@@H](O)C[C@H](O)C\4)=C)C)CC1=C
Biological Activity: 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[1][2][3].
