23983-43-9 Usage
Originator
Prasterone,Schering
Uses
Prasterone Enanthate is used in preparation of DHEA enanthates for treating/improving adrenal hormonal balance, immune system function, adipose tissue reduction, skeletal muscle growth, bloating reduction, recovery from training, and increasing strength.
Manufacturing Process
A mixture of 10.0 g of dehydro-epi-androsterone, 40 ml of pyridine and 20 ml
of oenanthic acid anhydride was warmed for 2 h on a steam bath. About 10
ml of water were added and the mixture was warmed for a further 30 min.
The reaction mixture was then subjected to a steam distillation. The resulting
mixture was extracted with ether and the extract was successively washed
with dilute sodium hydroxide solution, sodium carbonate solution and water.The solution was dried over sodium sulfate and exaporated. 13.6 g of crude
dehydro-epiandrosterone-3-oenanthate were obtained, melting point 70°-72°C
(recrystallisation from methanol).
Therapeutic Function
Glucocorticoid
Check Digit Verification of cas no
The CAS Registry Mumber 23983-43-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,9,8 and 3 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 23983-43:
(7*2)+(6*3)+(5*9)+(4*8)+(3*3)+(2*4)+(1*3)=129
129 % 10 = 9
So 23983-43-9 is a valid CAS Registry Number.

Esters of dehydroepiandrosterone (DHEA) as probes for the active site of type 3 17β-hydroxysteroid dehydrogenase (17β-HSD3)

We report the use of steroid-based compounds as probes for the active site of 17β-hydroxysteroid dehydrogenase, in particular, type 3 (17β-HSD3). Results suggest that the compounds were good inhibitors of 17β-HSD3 - a number were extremely potent with respect to the standard compounds used.
