General Description

"(S)-2-((1R,3aS,7aR,E)-4-((E)-2-((S)-5-((tert-butyldiMethylsilyl)oxy)-2-Methylene-cyclohexylidene)ethylidene)-7a-Methyloctahydro-1H-inden-1-yl)propanal" is a complex, multi-functional organic compound. The tert-butyldimethylsilyl group indicates that it likely undergoes or facilitates certain types of organic synthesis, likely acting as a protecting group for a sensitive hydroxyl group during a reaction. The compound also contains a cyclohexylidene unit and an octahydro-1H-inden-1-yl unit, both of which suggest a highly structured three-dimensional molecular geometry. The 'E' in the IUPAC name suggests presence of geometrical isomerism. The whole molecule also consists a methylene group, a functional group with a carbon atom bonded to two hydrogen atoms. The “propanal” part of this name further implies an aldehyde function present in the molecule. As a whole, this chemical likely participates in specific, fine-tuned organic reactions.

Check Digit Verification of cas no

The CAS Registry Mumber 112828-12-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,2,8,2 and 8 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 112828-12:
(8*1)+(7*1)+(6*2)+(5*8)+(4*2)+(3*8)+(2*1)+(1*2)=103
103 % 10 = 3
So 112828-12-3 is a valid CAS Registry Number.

Affinity-based protein profiling identifies vitamin D3 as a heat shock protein 70 antagonist that regulates hedgehog transduction in murine basal cell carcinoma

Hadden, M. Kyle,Wen, Jiachen

, (2021/11/30)

Vitamin D3 (VD3) is a seco-steroid that inhibits the Hedgehog (Hh) signaling pathway. Initial studies suggested its anti-Hh activity results from direct inhibition of Smoothened, a seven-transmembrane cell surface receptor that is a key regulator of the Hh signaling cascade. More recently, a role for the Vitamin D Receptor in mediating inhibition of Hh-signaling by seco-steroid has been suggested. Herein, an affinity-based protein profiling study was carried out to better understand the cellular proteins that govern VD3-mediated anti-Hh activity. We synthesized a novel biotinylated VD3 analogue (8) for use as a chemical probe to explore cellular binding targets of the seco-steroidal scaffold. Through a series of pull-down experiments and follow up mass spectrum analyses, heat shock protein 70 (Hsp70) was identified as a primary binding protein of VD3. Hsp70 was validated as a binding target of VD3 through a series of biochemical and cellular assays. VD3 bound with micromolar affinity to Hsp70. In addition, both selective knockdown of Hsp70 expression and pharmacological inhibition of its activity with known Hsp70 inhibitors suppressed Hh-signaling transduction in murine basal cell carcinoma cells, suggesting that Hsp70 regulates proper Hh-signaling. Additional cellular assays suggest that VD3 and its seco-steroidal metabolites inhibit Hh-signaling through different mechanisms.
