HOP-17(21)-ENE, also known as 17(21)-dehydroprogesterone, is a naturally occurring steroid hormone that belongs to the pregnane family. It is a key intermediate in the biosynthesis of various steroid hormones, including progesterone, cortisol, and aldosterone. HOP-17(21)-ENE plays a crucial role in the regulation of various physiological processes, such as inflammation, immune response, and stress. The chemical structure of HOP-17(21)-ENE consists of a pregnane core with a double bond between carbons 17 and 21, which differentiates it from other pregnane derivatives. Due to its biological significance, HOP-17(21)-ENE has been a subject of interest in the field of endocrinology and pharmaceutical research, with potential applications in the development of drugs targeting steroid hormone-related disorders.

546-99-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 546-99-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,4 and 6 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 546-99:
(5*5)+(4*4)+(3*6)+(2*9)+(1*9)=86
86 % 10 = 6
So 546-99-6 is a valid CAS Registry Number.

Bromine, N-bromosuccinimide and sulphur induced isomerizations in the hopane series

Bisseret, Philippe,Rohmer, Michel

, p. 7445 - 7448 (2007/10/02)

When reacted with bromine, N-bromosuccinimide or molten sulphur, triterpenoids of the 17β(H),21β(H)-hopane series were converted into their 17α(H),21β(H) and 17β(H),21α(H) isomers of geochemical significance.

Acid-Induced Rearrangement of Triterpenoid Hydrocarbons Belonging to the Hopane and Migrated Hopane Series

Ageta, Hiroyuki,Shiojima, Kenji,Arai, Yoko

, p. 2705 - 2716 (2007/10/02)

The acid-catalyzed rearrangement of triterpenoid monoenes belonging to the hopane and migrated hopane series with sulfuric acid and boron trifluoride etherate was investigated.By selecting the reaction conditions, a variety of the monoenes of these series, including three new compounds, 9βH-fern-7-ene (3c), 8βH-fern-9(11)-ene (4b), and adian-5(10)-ene (5b), were obtained.For comparison, oleanenes and migrated oleanenes were also subjected to the same reaction.Keywords--acid-induced rearrangement; triterpenoid hydrocarbon; hopane, migrated hopane; 9βH-fern-7-ene; 8βH-fern-9(11)-ene; adian-5(10)-ene; sulfuric acid; boron trifluoride
