25819-77-6 Usage

Uses

6β-Methoxy-3α,5-cyclo-5α-pregnane-20α-carboxaldehyde is an intermediate in the synthesis of Campesterol (C155360), a phytosterol, which may inhibit the intestinal absorption of cholesterol.

Check Digit Verification of cas no

The CAS Registry Mumber 25819-77-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,8,1 and 9 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 25819-77:
(7*2)+(6*5)+(5*8)+(4*1)+(3*9)+(2*7)+(1*7)=136
136 % 10 = 6
So 25819-77-6 is a valid CAS Registry Number.

Stereocontrolled synthesis of dafachronic acid A, the ligand for the DAF-12 nuclear receptor of Caenorhabditis elegans

Giroux, Simon,Corey

, p. 9866 - 9867 (2007)

An efficient synthetic route to the DAF-12 nuclear receptor ligand of C. elegans, dafachronic acid, is described that starts with the abundant plant sterol β-stigmasterol and proceeds in 37% overall yield. The synthesis establishes the structure of this r

Probing the mechanism of action of amphotericin B

James, Phillip R.,Rawlings, Bernard J.

, p. 505 - 508 (1996)

Transmembrane spanning dimers of cholesterol were unable to form ion channels with amphotericin B: We suggest that the two 'half pores' as proposed by De Kruijff may be aligned unsymmetrically.

Formal Semisynthesis of Demethylgorgosterol Utilizing a Stereoselective Intermolecular Cyclopropanation Reaction

Rosenbaum, Nicolai,Schmidt, Lisa,Mohr, Florian,Fuhr, Olaf,Nieger, Martin,Br?se, Stefan

supporting information, p. 1568 - 1574 (2021/02/26)

In this study, we report a convenient and high yielding formal semisynthesis of demethylgorgosterol, a marine steroid with an intriguing sidechain containing a cyclopropane unit. This was achieved through the synthesis of an advanced ketone intermediate.
