"3β,5,14β,21-Tetrahydroxy-24-nor-5β-chol-20(22)-ene-19,23-dioic acid γ-lactone" is a complex steroidal compound characterized by its unique molecular structure. It features four hydroxyl groups at the 3β, 5, 14β, and 21 positions, indicating the presence of oxygen atoms bonded to carbon atoms in these locations. The term "24-nor" suggests that the molecule lacks a carbon atom at the 24th position compared to a standard cholesterol structure, making it a nor-cholesterol derivative. The "5β-chol" part of the name indicates that the molecule has a 5β configuration, which refers to the orientation of the hydroxyl group at the 5th carbon. The "20(22)-ene" signifies the presence of a double bond between the 20th and 22nd carbon atoms, and the "19,23-dioic acid" part indicates that there are two carboxylic acid groups at the 19th and 23rd carbons. Lastly, the "γ-lactone" ending implies the presence of a lactone ring, which is a cyclic ester formed by the intramolecular esterification of a hydroxyl group with a carboxylic acid group. 3β,5,14β,21-Tetrahydroxy-24-nor-5β-chol-20(22)-ene-19,23-dioic acid γ-lactone is a specific type of steroid with potential applications in pharmaceuticals and chemical research due to its unique structural features and biological activities.

508-64-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 508-64-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,0 and 8 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 508-64:
(5*5)+(4*0)+(3*8)+(2*6)+(1*4)=65
65 % 10 = 5
So 508-64-5 is a valid CAS Registry Number.

Cardiotonic steroids with additional lactone rings

Makarevich,Kovalenko,Ulesov

experimental part, p. 742 - 745 (2011/02/25)

Stereochemical structural transformations of cardiosteroids to create in them additional lactone rings were studied. Creation of β-lactones by reaction of a 3β-OH group and a 19-carboxylic group to give the corresponding A/B-trans cardiosteroids and creation of β-lactones by reaction of a 5β-OH group and a 19-COOH to give the corresponding A/B-cis steroids were studied. The new biologically active compounds 8(14)-dehydrobovogenin-19-carboxylic acid 3β-O-19-lactone, strophanthidine-19-carboxylic acid 5β-O- 19-lactone, cymarin-19-carboxylic acid 5β-O-19-lactone, convallatoxin-19-carboxylic acid 5β-O-19- lactone, and strophalloside-19-carboxylic acid 5β-O-19-lactone were prepared.

19-NORCARDENOLIDES

Makarevich, I. F.,Dikan', L. N.

, p. 67 - 71 (2007/10/02)

The products of the autooxidation of the cardenolides strophanthidin and erysimin in solutions have been studied.It has been established that the autooxidation of 19-oxocardenolides forms, together with 19-carboxylic acids, a complex mixture of 19-norcardenolides.The bulk of them consists of 10β-OH compounds and a smaller proportion of 10β-H compounds.Autooxidation affects both the functional group at C-10 and its transformation and also other groupings and bonds in ring A and, to some extent, in ring B, including the oxidation of the 3β-OH group, degradation of the 5β-OH group, and cleavage of the C5-C10 bond with the formation of 5,10-seco-19-norcardenolides.A possible mechanism of the formation of 19-norcardenolides is discussed.
