3β,17,21-trihydroxy-5α,17βH-pregnanone-(20) is a complex steroidal compound belonging to the pregnane family, characterized by its unique molecular structure and functional groups. This chemical features three hydroxyl groups at the 3β, 17, and 21 positions, a 5α double bond, and a 17β hydrogen atom. The presence of these functional groups and the specific arrangement of atoms contribute to its distinct chemical properties and potential biological activities. While the exact applications and effects of 3β.17.21-trihydroxy-5α.17βH-pregnanone-(20) may vary, it is generally associated with the field of pharmaceuticals and could have implications in the development of drugs targeting hormonal or steroid-related conditions. Further research and analysis would be required to fully understand its specific uses and mechanisms of action.

7694-32-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7694-32-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,6,9 and 4 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 7694-32:
(6*7)+(5*6)+(4*9)+(3*4)+(2*3)+(1*2)=128
128 % 10 = 8
So 7694-32-8 is a valid CAS Registry Number.

A convenient synthesis of the side chain of loteprednol etabonate - An ocular soft corticosteroid from 20-oxopregnanes using metal-mediated halogenation as a key reaction

Chowdhury, Pritish,Borah, Juri Moni,Goswami, Papori,Das, Archana Moni

, p. 497 - 501 (2011)

A facile synthesis of the side chain of loteprednol etabonate, namely, chloromethyl-17α-[(ethoxycarbonyl))oxy]-11β-hydro of loteprednol etabonate, viz., chloromethyl-17α-[(ethoxycarbonyl))oxy]-11xy-3- oxoandrosta-1,4-diene-17β-carboxylate - an ocular soft corticosteroid, has been described starting from a 20-oxopregnane, namely, 3β-acetoxy-pregn- 5(6),16(17)-diene-20-one (16-dehydropregnenolone acetate, i.e., 16-DPA) using our recently developed metal-mediated halogenation as a key reaction.

Biotransformation of corticosteroids by Penicillium decumbens ATCC 10436

Holland, Herbert L.

, p. 646 - 649 (2007/10/02)

The biotransformation of a series of corticosteroids by the fungus Penicillium decumbens ATCC 10436 has been investigated. Conversion to the corresponding 5α-dihydroxteroid was observed for all the Δ4-3-ketosteroids studied with the exception of deoxycorticosterone, which was converted to a Δ14-diene. Deoxycorticosterone acetate was, however, converted to a 5α- dihydro product concomitant with ester hydrolysis. Other substrates carrying a C-21 acetoxy group were also hydrolyzed to the alcohol. In two cases (resulting from deoxycorticosterone acetate and 11-deoxycortisone) the 5α- 3-keto-product was further reduced to the 3β-alcohol. No reduction of δ14-dienes was observed.
