SMILES: C[C@@]1([C@@]2([H])[C@@](C)(O)CCCC(C)C)[C@](CC2)([H])[C@@](CC=C3[C@@]4(CC[C@H](O)C3)C)([H])[C@]4([H])CC1
Biological Activity: 20(S)-Hydroxycholesterol (20α-Hydroxycholesterol) is an allosteric activator that selectively targets the Smoothened (Smo) of the Hedgehog pathway with an EC50 of ~30 μM (Hedgehog). 20(S)-Hydroxycholesterol binds to the extracellular cysteine-rich domain (CRD) of Smo in a stereoselective manner, activating downstream Gli transcription factors (without inducing transcription of receptor genes in the Wnt pathway). 20(S)-Hydroxycholesterol enhances osteogenic differentiation of bone marrow stromal cells and synergistically activates the Raf/MEK/ERK pathway with Simvastatin (HY-17502) to promote bone regeneration. 20(S)-Hydroxycholesterol can be used to study the mechanisms of developmental biology, oncology, bone, and angiogenesis[1][2][3].
